DEPARTMENTS OF VETERANS AFFAIRS AND HOUSING AND URBAN DEVELOPMENT, AND
INDEPENDENT AGENCIES APPROPRIATIONS ACT, 1998
The PRESIDING OFFICER. Under the previous order, the hour of 3 p.m.
having arrived, the Senate will now proceed to the consideration of
Senate bill 1034, which the clerk will report.
The assistant legislative clerk read as follows:
A bill (S. 1034) making appropriations for the Departments
of Veterans Affairs and Housing and Urban Development, and
for sundry independent agencies, commissions, corporations,
and offices for fiscal year ending September 30, 1998, and
for other purposes.
The Senate proceeded to consider the bill.
Mr. BOND addressed the Chair.
The PRESIDING OFFICER. The Senator from Missouri.
Mr. BOND. Madam President, I thank the Chair.
Madam President, with my distinguished ranking member, I am pleased
to present to the Senate the fiscal year 1998 VA-HUD and Independent
agencies appropriations bill. This bill is not perfect, as is usually
the case with the measures that we present, and not everyone is fully
satisfied, but, nevertheless, every attempt was made to achieve a
balanced, fair bill which meets our highest priority.
While I am very grateful for the support of the appropriations
chairman in the allocation process, it should be recognized that the
allocation is slightly above the amount assumed in the budget
agreement. Our job was made extremely difficult once again this year by
an extraordinarily tight initial 602(b) allocation. I might add that we
are awaiting final Budget Committee action, which I expect will be
forthcoming shortly, to achieve the final allocation numbers.
The allocation represents a reduction of about $1.4 billion below the
President's request in outlays. Clearly, fulfilling the President's
request in many areas has been impossible under these numbers.
The bill totals approximately $69.4 billion in discretionary budget
authority, plus an additional $21.5 billion in mandatory spending.
Our highest priority was adequately funding VA medical programs,
which in the budget agreement took a $300 million cut. Protecting VA
medical care meant that fulfilling the President's full request for
EPA, for which a 12 percent or $850 million increase was requested,
simply was not possible.
In addition, the subcommittee did not apply cuts totaling $230
million to the National Aeronautics and Space Administration or the
National Science Foundation which were assumed in the budget agreement.
Finally, the budget agreement suggested that public housing,
community development block grants, the HOME Program for local
governments to assist in housing, and the McKinney
[[Page S7753]]
Homeless programs all be cut. Clearly, those cuts were unacceptable,
and we did not include them.
For the Veterans Administration the committee recommendation totals
$18.7 billion in discretionary funding, an increase of $92 million
above the President's request and almost $400 million above the amount
assumed in the budget agreement. Increases were provided to VA medical
care, research, and the State home construction grant program, the
latter of which demand far exceeds available Federal matching funds.
The recommendation for VA is predicated on enactment of
reconciliation legislation giving VA authority to retain collections
from third-party payers and copayments. Such collections are estimated
to total $600 million next year, and together with the medical care
appropriation will result in an increase over fiscal year 1997 of $617
million in available discretionary funding for VA medical care. The
amount recommended will enable VA fully to continue on the path of
improving the quality of health care services, increase the number of
veterans served, and increase the provision of care in ambulatory and
community-based settings.
The bill would also require VA to begin implementation of a number of
preliminary recommendations of the National Academy of Public
Administration report regarding the Veterans Benefits Administration.
These recommendations are intended to improve and expedite the
processing of veterans' claims for benefits. Addressing this problem is
long overdue.
For the Department of Housing and Urban Development, the committee
recommends $25.4 billion, including flat funding for most programs such
as CDBG, HOME, public housing, and homeless assistance. The budget
agreement assumes cuts in each of these programs. And as I indicated,
the committee did not accept that budget agreement recommendation.
In addition, the mark restores the President's budget cut of $365
million to elderly and disabled housing, with a total of $839 million
included in the recommendation for this program.
Furthermore, the bill provides $9.2 billion to fund section 8
contract renewals fully for which the budget resolution included a
special reserve account.
For the Environmental Protection Agency, the committee recommendation
totals almost $7 billion, an increase of $180 million over the fiscal
year 1997 level. While this recommendation is $680 million less than
the President's request, the reduction is attributable primarily to the
decision not to fund a requested 50 percent increase for Superfund.
Given that the Superfund Program is sorely in need of reform and
reauthorization, with the General Accounting Office designating it as a
high-risk program subject to fraud, waste and abuse, coupled with our
budget constraints previously described, a $700 million increase simply
could not be justified. Senators Chafee and Smith, chairman of the
authorizing committee and subcommittee respectively, have indicated
their opposition to a large boost in Superfund appropriations prior to
reauthorization and reform badly needed in that program. Finally, there
are serious questions as to whether EPA could even spend the full
amount being requested.
In terms of operating programs, which are up almost $100 million over
last year, the largest reduction--$122 million--below the request was
taken from a laboratory construction project in Research Triangle Park,
NC. Sufficient funds remain available to continue progress on the new
building at this time.
In addition, all major operating program accounts in the
Environmental Protection Agency will receive increases. Again, this
year the committee made as its highest priority EPA funding for States
for implementation of environmental requirements. A significant
increase is recommended for State revolving funds.
The committee recommendation restores the President's proposed $275
million cut to clean water State revolving funds and fully funds the
$175 million increase for drinking water State revolving funds, for a
total of $2.075 billion. These funds are vitally needed, Madam
President, with the EPA's estimate of drinking water and clean water
infrastructure requirements nationally exceeding $200 billion. I
believe every Member of this body, when she or he returns to their
State, will find that these priority needs are there. They are critical
and they are absolutely essential to maintaining the health of our
populace as well as the quality of our environment.
In addition, the committee recommends a $50 million boost to State
environmental assistance grants, in part for additional
responsibilities in the area of air quality standards, for a total of
$725 million. The leaking underground storage tank grants are increased
$5 million, for a total of $65 million. This program is vital in
protecting ground water resources.
To minimize controversy and expedite consideration of this bill,
there are no EPA legislative provisions included in the committee
recommendation. If Members wish to offer such amendments, we ask that
you bring them forward. We will deal with those in the full body. We
did not deal with them in committee.
For the National Aeronautics and Space Administration, the committee
recommends $13.5 billion for NASA, the same as the President's request.
The past few weeks in the news have exemplified NASA's situation, from
the heady excitement of seeing the American robot Sojourner cruising
the surface of Mars to the continued concerns over the safety of our
American astronaut and his Russian companions on the Mir space station.
We have supplied NASA with the President's request and will work with
the agency to allow them the flexibility to continue their exciting
research and development missions while at the same time working to
control their costs.
For the National Science Foundation, the recommendation includes
$3.377 billion for the National Science Foundation, $10 million above
the President's request and $60 million above the budget agreement
assumptions. This subcommittee believes that research and development
is essential to our Nation's future and wants to give the NSF the
necessary resources.
Included in the mark for NSF funding is the provision for a new plant
genome initiative. An interagency working group convened by the
President's science adviser has recently reported on the exciting
prospects in genome research. Their report recommends expanding current
studies of plant genomes to economically important crop species,
including corn. We have supplied NSF with the resources to jump-start
that effort and applaud the agency's interest and support in exploring
the broader applications of the research they fund.
For the Federal Emergency Management Agency, the recommendation
totals the President's request of $788 million exactly, including $320
million for disaster relief. A prohibition on spending is included in
the recommendation, consistent with legislation FEMA recently proposed
to reform the disaster relief account. This is an area I have long been
interested in addressing, as the costs of this program are completely
out of control. The limitation on spending included in this measure as
recommended by FEMA would prohibit disaster relief funds from being
spent on such projects as golf courses, stadiums, parks, and
recreational facilities, trees and shrubs. While the limitation on
spending is modest, it is at least a first step, long overdue, and an
important one that we should take. I anticipate the authorizing
committee will expedite its consideration of FEMA's proposed Stafford
Act amendments in September.
Also in FEMA, the newly authorized dam safety program is fully funded
at $2.9 million and State and local assistance grants are increased $3
million.
I might add that, as mentioned earlier, we are waiting final action
from the Budget Committee to revise the 602(a) allocation, which is
anticipated shortly, after which the subcommittee 602(b) allocation
will be revised so that we may be in conformance with that allocation.
The action is necessary owing to the budget resolution's special
treatment of the HUD section 8 contract renewal accounts.
Privilege Of The Floor
Mr. BOND. Madam President, I ask unanimous consent that Sarah
Horrigan, who has worked on space and science issues on this bill, be
allowed
[[Page S7754]]
the privilege of the floor during consideration on S. 1034, the VA-HUD
appropriations bill and any votes therein.
The PRESIDING OFFICER. Without objection, it is so ordered.
Mr. BOND. Madam President, it is now my pleasure to yield to my
partner in this effort, the distinguished Senator from Maryland.
I yield the floor.
Ms. MIKULSKI addressed the Chair.
The PRESIDING OFFICER. The Senator from Maryland is recognized.
Ms. MIKULSKI. Madam President, thank you very much.
Privilege Of The Floor
Ms. MIKULSKI. Madam President, I now ask unanimous consent that
during the consideration of S. 1034, the VA-HUD appropriations bill for
fiscal year 1998, Ms. Stacy Closson, a detailee from DOD serving with
the VA-HUD Subcommittee be provided floor privileges during the
consideration of this bill.
The PRESIDING OFFICER. Without objection, it is so ordered.
Ms. MIKULSKI. Thank you, very much, Madam President.
Today, I rise to join my distinguished colleague, the Senator from
Missouri, to offer for floor debate and the consideration of the Senate
the fiscal year 1998 appropriations bill for VA-HUD and independent
agencies.
This is an extraordinary bill because it deals with 7 Cabinet-level
Government agencies and 18 other agencies that are important to the
United States of America. These agencies range from Veterans, Housing,
the Environmental Protection Agency, the National Space Agency, the
National Science Foundation, Federal Emergency Management Agency, as
well as the National Corporation for Volunteer Services, and we go on
to Selective Service.
People would be surprised to know that Arlington Cemetery is also
funded in this bill. We stand sentry for consumers through the consumer
product safety legislation. Those little pamphlets that taxpayers send
for from Pueblo, CO, a big chunk of their funding comes out of this
bill. So when we say veterans, housing, and independent agencies, this
is probably, along with defense and the Labor-HHS bill, the most
complex bill. Therefore, when we bring it to the Senate, sometimes our
funding sounds like it is significant in terms of its dollar amount,
but we really have worked very hard to get a dollar's worth of services
for a dollar of taxes.
The bill before the Senate is a $90 billion bill that includes $21.5
billion in mandatory spending which is primarily directed at veterans,
and appropriates a total of $69.4 billion in discretionary budget
authority. This is almost equal to the House in total funding, and more
than $90 million below what President Clinton requested. However, the
allocation for the Senate, which is the total amount given to us to
spend, was almost $800 million below that of the House.
Given the tight allocation, the chairman and I did the best we could
to balance the needs of diverse groups of agencies funded within this
subcommittee. With a better allocation, we could have funded all the
agencies in this bill at higher levels. But we were ready to make tough
choices and set priorities.
On the majority of the aspects of the bill, I want to say
unequivocally I support Senator Bond, the chairman of the committee,
the Republican, on his priorities. There are some yellow flashing
lights related to President Clinton's agenda that I will address in my
remarks, but we are very much in sync and in alignment with what we
want to do. I am particularly grateful for Chairman Bond's efforts
reflected in this bill to continue many of the initiatives voted by the
subcommittee over the past several years when I chaired it.
As I said, I wholeheartedly agree with Chairman Bond's attempt also
to avoid controversial riders this year and to keep out significant new
legislative provisions not dealt with by this subcommittee. We have
essentially said to Democrats and Republicans alike, don't play pin the
tail on the donkey with this bill, adding controversial riders, and
also, if you have new ideas for new initiatives, hey, why not try the
authorizing committee for a change and see if we can move legislation
that way.
There are several things, though, that I really approve of in this
bill. Both Chairman Bond and myself consider veterans to be a very high
priority and veterans medical programs to be of special priority. This
bill restores $300 million worth of cuts assumed in the budget
agreement and puts them in veterans medical care and also in veterans
medical research. Veterans funding remains a key concern of mine, and I
will continue to fight to ensure that promises made are promises kept.
I will also stand sentry to make sure that the Veterans Administration
meets its projections in third-party insurance collections that are
designed to help increase medical care spending.
This bill also restores several cuts made to key programs at the
Department of Housing and Urban Development. This was restored as the
community development block grant funds so important to mayors and
local communities, the project HOME, public housing and homeless
assistance.
Also, something I am particularly pleased to work with Chairman Bond
on is we restored the cuts in elderly and disabled housing. When the
budget agreement was first proposed, there was a suggestion that this
particular area of funding receive $400 million. Senator Bond and I
agreed we should fully fund it at last year's level and have $839
million that will go to being able to build housing for the elderly and
for the disabled.
The Senate bill has also added a modest increase to the Hope 6
revitalization program. This is a program that is very important
because, hopefully, it ends public housing in the way we know it and
says that public housing should not be a way of life, but be a way to a
better life. Always where there is compelling need there is often
sometimes sloppy administration. I concur with the report language
offered by Senator Bond directing the Government Accounting Office to
continue its analysis of Hope 6 to make sure that the effectiveness of
the program is being monitored to ensure that for those receiving Hope
6 benefits in public housing, which was designed to community build and
have work force readiness, the GAO will make sure that the work force
readiness aspect is really doing what it should.
Then we move on to our very important science programs as well as
Federal Emergency Management. Thanks to the efforts of this
subcommittee, the national space agency, the National Science
Foundation, and Federal Emergency Management are all funded at the
President's request level. We, on this side of the aisle, say thank
you, thank you to Chairman Bond for working with us to make sure that
core science programs are funded and Federal Emergency Management
continues to be fit for duty should other people around the United
States have to dial 911. I think all of us who watched Hurricane Danny
were glad it was downgraded to a tropical storm, but when it hits
Alabama with over 25 inches of rain in a very short time and you see
people carrying out their children and their most precious possessions,
we know why FEMA exists.
Despite the tight allocation, I am pleased we were able to meet the
President's request for these key agencies while protecting the funding
in veterans medical care, disaster relief, critical science and space.
I think America has to be incredibly thrilled with the breakthroughs
NASA has made as Sojourner continues to roll across Mars. Scientific
developments, such as the Sojourner, the Hubble telescope, Mission to
Planet Earth, are truly special American projects, and show that we are
No. 1 in space. FEMA is another agency that is doing a very good job,
and this critical agency has shown steady improvement in recent years
in responding to America's natural disasters.
Madam President, I also want to call to your attention the fact that
the administration does have some serious concerns with the reductions
in this bill. I call these yellow flashing lights. Given the tight
allocation, I understand that not all the programs could be funded at
the President's request. Measures had to be taken, protective measures,
for several key programs. That meant that other important initiatives
could not be adequately addressed. So, in looking out for veterans'
medical care, that meant fulfilling the President's full request for an
$850 million increase to the EPA budget
[[Page S7755]]
simply was not possible. As a result, the request for a 50-percent
increase in the Superfund was not yet met.
As you know, the President is a strong advocate of the Superfund.
This will be a key issue to resolve during the upcoming weeks while the
House and Senate are in conference on this bill. I really encourage the
authorizers, while we are in conference, to try to pass the authorizing
bill so that the authorizing bill could match, perhaps, what we were
able to do in conference.
Another yellow flashing light is the $146 million reduction to the
President's request for the Corporation for National and Community
Service. This request was to be used for the President's program called
the America Reads Challenge. It is to be a national literacy campaign
to ensure that every child can read, and read well and independently,
by the third grade. The budget agreement called for funding in this
program. However, it was not funded in either the House or the Senate
bill.
Illiteracy in this country is of great concern for all, and all ages,
but, really, if we could make sure every child was immunized by the
time they were 2, could read by the time they were in third grade, had
access and knew how to use a computer by the time they were 12, we
would do a lot about empowering our children. I support the restoration
of that funding.
A third flashing light to the administration is the elimination of
funding for the community development financial institutions, something
called CDFI, another program that was protected in the budget
agreement, which helps to spur business activity and traditionally
underserved communities, and is particularly focused on microenterprise
endeavors that enable women of modest means to be able to move in terms
of economic development in business. The House bill funded this at $125
million, and we hope this will be a restoration where there is some
type of agreement. This is a high priority of mine during the
conference.
It will be my intent to offer an amendment or perhaps work with
Senator Bond as we go through the other amendments to see if we could
not address the issues of empowerment zones, America Reads, and Federal
emergency mitigation efforts to see if we could find some funds to be
able to have a placemarker in this budget going to conference for these
very important programs.
I do appreciate Chairman Bond's willingness to fund the EPA
brownfields request and the inclusion of the report language allowing
the HUD-CDBG money to be used for brownfield activities. A concern for
the administration is the absence of the request of increase for the
HUD brownfields program. The brownfields initiative can play a critical
role in restoring urban areas. In my own home State of Maryland, in the
Baltimore metropolitan area alone, we estimate that there are over
3,000 acres of brownfields in and around our port area which, if we
could clean them up, would offer kind of a second version of an
empowerment zoning.
Madam President, given these concerns, I will be offering an
amendment, as I said, that will restore funding, some funding, modest
funding, for the America Reads Program under the Corporation for
National Service, empowerment zoning in the HUD budget and predisaster
mitigation for FEMA. I will in no way make an effort to restore full
funding for those programs, because it just is not fair. But I will be
looking to see what we could do to have a placemarker to go to
conference.
Madam President, there is mixed news in this bill for the
administration. Like you, I am interested in producing a final bill
that is agreeable and signable. I believe the bill that we have
produced is a very good start. In fact, it is an excellent start to
ensuring funding for many of this Nation's vital programs. I will work
with my colleagues now on the floor to see how we could accommodate
them. I will work with my chairman during conference and continue to
try to address the administration's concern.
In closing, I want to thank Senator Bond again for his hard work and
his willingness to listen to my side of the aisle's concerns and to
honor many of the requests made by President Bill Clinton. I am
pleased, when it came to funding like NASA, like the National Science
Foundation, the funding for Federal Emergency Management, it knew no
party, because when we are up there on Sojourner, when we might have to
be part of the rescue operation for Mir, when we are doing so many very
important things at the National Science Foundation and helping rescue
Americans who have been hit by national disasters, this is not about
party. I commend the cooperative nature in which this bill has been
crafted. I believe we have produced a bill that can be signed into law
with some of the appropriate amendments in conference consideration.
Madam President, before I yield the floor, I say to all of my
colleagues from my side of the aisle, if you have amendments, please
let us know them. We know that between now and 5:15 when we start
voting on Treasury, Post Office, it would be enormously useful to
Senator Bond and myself to know what any amendments are so that we
could either work with you to accommodate you or be able to set the
stage on how we can proceed with this bill. I believe it is Senator
Bond's intention, and I will do my best to cooperate with him, that we
will conclude this bill tomorrow at the earliest possible time.
Having said that, I look forward to the debate, as always, on this
bill and, as always, have enjoyed working with my colleague, Senator
Bond. I yield the floor.
Mr. BOND. Madam President, when major measures like this are
considered on the floor, it is usually boilerplate for each side to say
nice things about the counterpart. In the case of the VA-HUD bill--this
is a very difficult bill--I say without reservation, and not as a
matter of mere formality, that one of the great benefits I have in
working through a very, very difficult bill is that I have the
distinguished Senator from Maryland as my ranking member. She has
helped me a great deal learn and understand many of the great
challenges in this bill from her position as having chaired this
committee. She has presented to us, in very workable fashion, a number
of the concerns we have been able to meet in this bill, and I really
could not be here with this difficult a bill in as good a shape as I
believe it is without her support. It has been absolutely invaluable to
me to have her assistance and that of her able staff.
She mentioned a modest amendment that I look forward to working with
her to include.
I guess my whole concern over this bill--it was with a slight tear in
my eye that I read the statement of administration policy from Budget
Director Raines. He said some nice things about working with the
committee. On the first page of his letter, he said, ``We urge the
committee to reduce funding for lower priority programs or for programs
that would be adequately funded at the requested level and to redirect
funding of programs of higher priority.''
Unfortunately, we have looked at the programs. We have not funded the
lower priority programs to the best of our ability. The priority
funding that we have included in this bill does reflect the priorities
of what I hope will be a bipartisan majority of this body. We do have
the option when we go to conference, we hope, of increasing the overall
allocation, so that there will be more funds available, and that we
will be able to put some more money in the higher priority programs.
But given the nature of the allocation and the many pressing needs, as
my ranking member has outlined and as I have outlined, there are not
low-priority programs funded in this bill.
I note that on the America Reads Program, it has not been authorized.
We don't really have any details on it yet. So we were reluctant to go
forward with the President's full request. When I first heard about it,
I thought it would be a program that would be funded in Labor-HHS if it
is a reading program. But I am certainly willing to work with my
minority colleagues in trying to make some accommodation of the
President's interests there.
With respect to the brownfields HUD program, I have said on this
floor many times that HUD is a very troubled agency that is having a
great deal of difficulty running the programs it is supposed to run.
That is why I am reluctant to give it a new responsibility in the
environmental area. EPA is handling that program. We have included
[[Page S7756]]
money for the EPA for the brownfields program. We made brownfields
clean up an eligible activity for the community development block
grants, so that communities without an undue benefit, Federal
bureaucratic interference, might be able to clean up some of them
themselves. So we feel that the brownfields program is not one that
ought to be added to HUD's already too-full plate.
After speaking briefly with my ranking member, I join with her in
urging our colleagues to bring forward the amendments. We hope to know
by 10 o'clock tomorrow what amendments are pending. We want to be
accommodating. We want to accommodate our colleagues if they do have
amendments and, if possible, we would try to accommodate them. If we
simply do not see the resources available, we would like to move
expeditiously to a vote on it, if that is required. I am most
encouraged by the optimistic thought that we could finish this very
important bill by not too late tomorrow. I am from Missouri and it is
the ``show me'' State. I will believe it when we have final passage.
But I commit to working with the ranking member and all of my
colleagues.
In the past, we have been swamped at the end with a large number of
colloquies and senses of the Senate. I have found, through very painful
experiences, that I need to read those and make sure that we have time
to consider them fully on both sides. So if colloquies or other
noncontroversial items are to be inserted, it would be of great help to
me and I would appreciate it, as my ranking member would, if we could
see those colloquies as soon as possible, so we will be able to give
them full consideration.
Now, Madam President, I had hopes that one of our very distinguished
colleagues would be able to be over this afternoon. We heard that
Senator Glenn might wish to come and talk about the space station. We
are open and we are ready to do business. We will be more than happy to
entertain any measures. If any colleagues have an amendment that may
need to go to a voice vote, we would like very much to lay it down
today. We have both the time from now until 5:15 and then after the
votes to do it. It is the request, I believe, of the leaders that we
move forward. If there is an amendment that we can debate and set for a
vote tomorrow morning, we would like very much to do so.
Madam President, I yield the floor.
Ms. MIKULSKI. Madam President, I, too, am looking forward to the
statement on the space program of our distinguished colleague from
Ohio. I have been advised by his staff that the distinguished Senator
from Ohio is in a meeting and hopes to join us perhaps around 4. In the
meantime, if any other Senators have statements they wish to make, they
could do that, and this might be a good time to offer an amendment.
Madam President, I yield the floor.
Mr. BOND. Madam President, I suggest the absence of a quorum.
The PRESIDING OFFICER. The clerk will call the roll.
The assistant legislative clerk proceeded to call the roll.
Mr. GLENN. Mr. President, I ask unanimous consent that the order for
the quorum call be rescinded.
The PRESIDING OFFICER (Mr. Hagel). Without objection, it is so
ordered.
Mr. GLENN. Mr. President, if there is anything that sets this country
apart from other nations around the world, it seems to me it would be
our, almost our innate curiosity, our questing spirit that led people
not only to explore geographically, but led them to explore in the
laboratories of our Nation and express our curiosity in learning new
things. That is at the heart of science, learning the new and putting
it to use. We could run through a whole gamut of things in history. We
could talk all night tonight about different things that have
revolutionized our way of doing things on Earth.
The Wright brothers were curious about whether we could fly or not,
whether you could get the air to react enough off an airfoil so you
could fly--and they were ridiculed for it. Some people said, ``If God
wanted us to fly, why, he would have made feathers on us so we could
fly.'' Their curiosity led to airplanes and the aviation industry and
changed the nature of the whole world. You can say the same thing about
curiosity about the internal combustion engine and automobiles and
communications and how we transmit sounds from one place to another--
the telephone, the Bells--computers and plastics and TV and nuclear
energy and agricultural research.
We never think of agriculture in this country as being such an
example of basic research, yet, just in my own lifetime, the corn
production in Ohio has gone from about 48 bushels per acre to something
like 137 on the average and, in some places, going close to 240 bushels
an acre in certain selected spots. That is just enormous. That did not
occur because people are working three or four times as hard. It
occurred because of basic, fundamental research, people curious about
soil and about fertilizer and seeds and hybrids and so on. We can go on
with antibiotics and anatomy and physiology and all the things we know
in medicine these days. We could talk for many hours about where this
questing, curious nature that we have in this country has led us.
Part of the bill before us here involves the NASA budget. An area
where we, as a nation, are expressing our curious, questing nature, is
in the area of space and space research. Every year we are asked why do
we invest billions of taxpayer dollars for space exploration and
research. There is one very short answer to it. In my view, we do it is
to benefit people right here on Earth. This has been true for the whole
program. It was true ever since I was involved in the space program
many years ago, during Project Mercury and our first orbital flights.
There are a number of examples of research connected just with the
space program, and particularly with the space shuttle experiments,
that I think everyone can relate to.
We will have applied science and scientific research going on through
the years with the international space station project. Every year we
debate this on the floor. Fortunately, to my way of thinking, we have
continued to fund the space station. It is one of the greatest
scientific engineering cooperative efforts in the history of this
world. We have a number of things that are being looked into now on the
shuttle that could be done better and longer term on the international
space station when it comes along. Parts of it will start being put up
at the end of next year. But a lot of things that have come out of the
shuttle program so far are of very, very practical use right here on
Earth.
One experiment that I find most intriguing is protein crystal growth.
It is fascinating. It brings a whole new input to medicine, to the
thousands of different proteins and combinations that make up our
bodies and literally stands to transform the way medicine looks at
itself and the way we treat disease and what we can do with regard to
immunities.
Let me give just one example. We have a chart here I would like to
have put up that shows what is going on with treating flu. A flu remedy
is being developed with space-grown crystals, where you can better find
out how the flu bug itself reacts. The loss of productivity due to flu
is staggering. Its costs range as much as $20 billion a year. There are
high-mutation rates of the flu virus. New data from the protein
crystals grown in space and on Earth have unlocked the secret of the
flu bug and revealed its Achilles heel. The secret lies in a small
molecule which is attached to the host cell's surface and each flu
virus, no matter what strain, must remove this small molecule to escape
the host cell to spread infection.
But using data from space and Earth-grown crystals, researchers from
the Center of Macromolecular Crystallography are designing drugs to
bind with this protein's active site, in other words, the lock on this
site. This lock-and-key reduces the spread of flu in the body by
blocking its escape route.
In collaboration with its corporate partner, the CMC, the Center of
Macromolecular Crystallography, has refined drug structure in
preparation for clinical trials, and those clinical trials are
starting. When tested and approved, relief is expected from flu
epidemics by the year 2004. I give some detail on that because I think
it is an example of the kinds of things that are underway that we can
directly relate to the space program. We have some 20 to 40 million
people every year that get
[[Page S7757]]
the flu, and it causes some 20,000 deaths a year in the United States
alone. This new data of space-grown crystals has helped unlock a secret
to let us treat flu in a different way. That is just one example.
Another example that can benefit from these same kinds of space-grown
crystals is trauma from open-heart surgery, which often may lead to
complications due to massive inflammation of heart tissue. Factor D is
a protein which plays a key role in the biological steps that activate
this immune response. Being able to block factor D's effects could
enable heart surgery patients to recover more rapidly, and data from
space-grown crystals allowed researchers to develop inhibitors which
specifically block factor D. This drug is being readied for clinical
trials.
We have a new antiparasite drug from space-grown crystals. It is
estimated that over 1 billion people in this world are infected with a
round worm known as ascarids. It is a tiny parasite that infects the
intestinal tract of vertebrates and is often fatal. Ascarids are
dependent on a substance called malic enzyme to function properly. A
new drug, developed in part by Upjohn, with the benefit of crystals
grown on the USML-1 Spacelab mission, should interfere with normal
functioning of malic enzyme and, thus, prove deadly to ascarids.
Another example: Space crystals and the fight on AIDS. A new
combination of drugs, which include protease inhibitors, have proven
immensely successful in treating AIDS. In an ongoing experiment with
DuPont Merck, NASA has crystallized HIV protease enzyme with an
inhibitor to support structure-based drug design research, and the
resulting drugs could represent the second generation of this
successful approach to treating this disease.
This chart shows some of the details. I don't know whether the
cameras will pick this up well enough to show the interaction. This is
something that gives real hope in the treatment of AIDS in the future.
Another example on a different chart here indicates how diabetes
patients may benefit from NASA's bioreactor research. The bioreactor is
a tissue culturing instrument which allows microgravity researchers to
grow tissues which are larger and more complex than other tissue
culturing techniques. The bioreactor has the potential for changing
disease treatment through tissue transplants.
Forthcoming experiments plan to grow human pancreatic islet cells in
the bioreactor for possible transplantation into diabetic patients.
Trial runs with this technique have proven successful. If the upcoming
experiments are successful, diabetic patients will not need to rely as
heavily on insulin injections and will have less complications from
their disease.
Another chart: Modeling colon cancer with bioreactor. Mr. President,
166,000 cases of colon cancer are diagnosed each year in the United
States, and it is a leading cause of death. Colon cancer tissue grown
in a bioreactor develops remarkably similar to tumors extracted from
humans. Studying these tissues outside the human body may allow
researchers to understand how cancer spreads, as well as identifying
new therapies which may prevent it.
This bioreactor is a fascinating thing. It lets tissues be cultured
in the same way they occur in the human body. If you go into a
laboratory and try to do experiments there, quite often the experiment
becomes far more two-dimensional because it wants to settle to the
bottom of the petri dish. A bioreactor in space, with all the right
fluids that simulate the body, allows growth in a 3-D situation. They
can be studied better so possible antidotes for them or possible
treatments can be put into a culture there that is very similar to what
is in the human body. It is not just something that is flattened out in
the bottom of an experimental glass in the laboratory.
Growing cartilage with the bioreactor is another potential
application. An application of the bioreactor is culturing cartilage
tissue for replacement and transplantation. Experiments with the
bioreactor and space indicates it can successfully culture cartilage
tissue that is quite similar to human cartilage.
I use these few examples today just to illustrate that they are very,
very practical and very, very useful for our future on Earth. The
international space station will make it possible to continue some of
the same experiments for longer periods of time. I know that every year
when we have the budget battles on the floor, we have attempts made to
cut out some of the money for the international space station, which
would cut out some of the scientific inquiry that we otherwise would be
able to perform. Let me talk about it very briefly.
NASA has already had some 1,000 or more proposals per year for
ground-based and flight investigations involving the international
space station project. Selection of principal investigators and
commercial developers is beginning this year for flights starting in
1999, and this population will increase from 650 to 850 principal
investigators and from 100 to 200 industrial affiliates by the time the
station assembly is complete.
About 650 life and microgravity sciences principal investigators are
now participating at over 100 institutions of higher learning around
the country, and the number of investigators is expected to grow to
over 850 before assembly is completed. These researchers, in turn,
employ about 1,400 graduate students at present, with that number
expected to grow.
What are they looking into? Well, a number of different areas, and I
won't be able to go into all of them today. Biotechnology with an x ray
diffraction system, for instance. Microgravity allows researchers to
produce superior protein crystals, which I mentioned a moment ago, for
drug development and to grow three-dimensional tissues, including
cancer tumors, for research and cartilage for possible transplant.
The long-term benefits: to provide information to design a new class
of drugs to target specific proteins and cure specific diseases; to
culture tissue for use in cancer research and surgery in bone and
cartilage injury.
Another area that can be looked into on the international space
station also is in the area of materials science. Researchers use low
gravity to advance our understanding of the relationships among the
structure, the processing and the properties of physical materials.
The long-term benefits: We advance the understanding of processes for
manufacturing semiconductors, metals, ceramics, polymers, and other
materials. We also determine fundamental physical properties of molten
metal, semiconductors, and other materials with precision impossible on
Earth.
There are a number of people involved in this, people from the State
University of New York, Rensselaer Polytechnic Institute, and MIT up in
Boston. Researchers indicate great progress from this new research tool
in having projects in space in microgravity.
Another area being looked into, and this one is a fascinating one, is
combustion science, fluids and combustion facility, glove-box
experiments, as they are called. Scientists are using low gravity to
simplify the study of complex combustion processes, burning processes.
Since combustion is used to produce 85 percent of Earth's energy, even
small improvements in efficiency will have large environmental and
economic benefits.
The long-term benefits: Improved control of combustion emissions and
pollutants reduce risk from incineration of hazardous wastes and
enhance efficiency of combustion processes.
These are only highlights of some of the prestation research that
have already occurred. Dr. Robert Cheng and Dr. Larry Kostiuk,
combustion science researchers at Lawrence Berkeley National Laboratory
under contract to NASA, were awarded a patent for a ring flame
stabilizer, which significantly reduces pollution from natural gas
burners. Fitted into an off-the-shelf home heating surface, the device
reduces nitrogen oxide emissions by a factor of 10 by increasing
efficiency by 2 percent, and the device can be readily sized to
industrial scales. That kind of experiment will continue on the space
station.
``Almost every chapter in the combustion textbooks will be rewritten
as a result of the microgravity work,'' said Prof. Howard Palmer,
professor emeritus at Penn State University. And other statements by
other scientists say the same thing.
[[Page S7758]]
Furthermore, the international space station will continue research
into fundamental physics. Scientists use low gravity to test
fundamental theories of physics with degrees of accuracy that far
exceed the capacity of earthbound science. Physics and low gravity
expand our understanding of changes in the state of matter, including
those changes responsible for high-temperature superconductivity.
The long-term benefits will challenge and expand our theories of how
matter organizes as it changes state, and that is especially important
in understanding superconductivity and its advantages. We can also test
the theory of relativity with precision beyond the capacity of
earthbound science.
Scientists will study gravity's influence on the development, the
growth and the internal processes of plants and animals, and their
results expand fundamental knowledge to benefit medical, agricultural,
and other industries.
The long-term benefits will improve the overall health of people of
all ages. It can improve plants for agriculture and for forestry, and
we will gain an advanced understanding of cell behavior.
Biomedical research in space will provide unique insights into such
things as how the heart and lungs function, the growth and maintenance
of muscle and bone, perception cognition, and balance, the whole area
of neuroscience, and the regulation of the body's many systems, called
regulatory physiology.
The long-term benefits will assist in developing methods to keep
humans healthy in low-gravity environments for long, long periods of
time; advance new fields of research in the treatment of diseases;
enhance medical understanding of the role of force on bone in disease
processes, including osteoporosis; advance fundamental understanding of
the brain and nervous system and help develop new methods to prevent
and treat various neurological disorders. These are the long-term
benefits.
I quote a friend and one of the most respected surgeons in this
country--as a matter of fact, in the world--Dr. Michael DeBakey,
chancellor and chairman of the department of surgery, Baylor College of
Medicine, who said:
The space station is not a luxury any more than a medical
research center at Baylor College of Medicine is a luxury.
Present technology on the shuttle allows for stays in space
of only about 2 weeks. We do not limit medical researchers to
only few hours in the laboratory and expect cures for
cancer. We need much longer missions in space--in months
to years--to obtain research results that may lead to the
development of new knowledge and breakthroughs.
We also can either look out into space or, from an observation point
in space aboard a spacecraft, the international space station, look
back toward Earth. That is planned with the Earth Observation and Space
Science, the Alpha Magnetic Spectrometer, and SAGE to be deployed in
2001.
The space station will be a unique platform with multiple exterior
attach points from which to observe the Earth and the universe.
Conceptualized by Nobel prizewinning scientist Dr. Sam Ting, of MIT,
the alpha magnetic spectrometer experiment will search the universe for
antimatter and ``dark'' matter in an attempt to prove cosmological
theory with direct evidence.
Also, the stratospheric aerosol and gas experiment, SAGE-III, will
also be delivered. It will obtain global profiles of aerosols, ozone,
water vapor, and oxides in order to determine their role in
climatological processes. It will allow cross-correlation of
observations from SAGE's I and II at different latitudes and different
time periods.
I cite these examples to briefly indicate what a wide variety of
scientific effort will go on with the international space station.
Now, let me address these next remarks to two sets of people who may
be watching or listening here today. How many of you are over 60 years
of age? If you are not over 60 years of age I know that each of you
hopes to live to be 60 or older. What I am about to say I believe is
very relevant to you.
For several years now NASA and the National Institute on Aging, which
is part of the National Institutes of Health, have been working on some
projects looking at what happens to astronauts in space.
I became intrigued with this, and I have long been interested in
issues associated with our aging population. In fact, when I first came
to the Senate--I was sworn in in January 1975--I asked to be assigned
to the Special Committee on Aging because I thought there was so much
work needed to be done.
Today, we find an aging population sometimes referred to as the
graying of nations. I conducted hearings years ago on the graying of
nations, and then had additional Governmental Affairs Committee
hearings in New York called the Graying of Nations II. Dr. Robert
Butler assisted in putting together those hearings. He was the first
Director of the National Institute on Aging and did a superb job in
getting that whole agency started.
Nearly 45 million Americans today are 60 years of age or older. The
demographic experts tell us that that is projected to grow to about 100
million over the next 50 years, by the year 2050. NASA has begun to
formally explore the similarities between the aging process and what
happens to astronauts in microgravity. There are physical changes that
occur in space and the National Institute on Aging has been very
interested in and has worked with NASA to review these changes. They
are in the process now of coming up with very specific proposals as
specific experiments.
But there is a great similarity between what happens to astronauts in
the short term--it starts 3 to 5 days after they have been up there on
current missions--and what happens to the elderly right here on Earth
by the normal process of aging. This is fascinating because of the
similarities in osteoporosis, for instance, changes in bone density,
changes in orthostatic intolerance--in other words, the ability of the
body to keep blood in the upper part of the body so you do not just
black out--the vestibular and balance problems, sleep disturbances,
decrease in muscle strength, the decrease in immune response, and
similar changes in cardiac activity and blood glucose.
Now, these changes occur in the younger astronauts in space right
when they go up today. They occur during the first 3 to 5 days, or are
noticeable, as I understand them, in the tests that have been run. At
the end of the flight when they come back to Earth, the younger
astronauts return to normal, their bodies recover, their bone structure
is basically reformed again. They recover from it.
Now, in the elderly here on Earth there is not that same kind of
recovery. But what the National Institute on Aging and NIH is looking
into with NASA is to propose experiments to see what happens if you did
put an older person into space. What would happen? Would the changes
that happen to the younger astronauts be additive to the older
astronaut or would that person be semi-immune from those same changes?
Would the change be to the same degree? What happens when you come
back to Earth again? With these changes, would the older astronaut
recover as fast as the younger ones? If not, why not? In other words,
the questions being asked are basically what triggers these different
systems and why do they change? Why do they change in microgravity? Why
do they change in orbit? Would they change the same for an older person
as they do for the younger people? I think this is a fascinating field.
I am very hopeful that NASA and NIA will formalize this program
primarily for the potentially enormous benefit that may come from it
for hundreds of millions of people, not just people in this country,
but people literally all over the world, and also because I can think
of no more powerful and essentially untapped constituency for human
research in space than the elderly.
I will say a few words about the importance of international
cooperation in space research, also.
If you had told me some 35 years ago when I made my flight back in
1962 that in June 1997, a U.S. astronaut would be beginning the 16th
month of continuous U.S. presence on a Russian space station, I
certainly would not have believed it.
As a veteran of the cold war and the space race, I guess I could not
be more pleased to see this kind of progress. Obviously, there is
tremendous symbolic value when former enemies work together
cooperatively. But symbolism
[[Page S7759]]
isn't the most important reason we cooperate. Again, it gets back to
basic research. The quality of research is going to improve if we have
the best and the brightest from 15 nations working on a project.
The shuttle-Mir program, also called phase I of the international
space station, is a perfect example of the benefits of such
cooperation. As many of you know, this program consists of nine
shuttle-Mir docking missions. The program is helping both the United
States and Russia learn countless valuable lessons which will be put to
use on the international space station.
Now, obviously, the Mir space station has been having problems. We
are aware of those from the daily news. Some problems are due to aging
components of the station; some may have been due to crew or ground
control errors. We will see what NASA and the Russian space agency
leadership will recommend.
Usually, for both the Russians and the Americans, space operations
have been nearly flawless. For example, just a few days ago, the crew
of STS-89 returned from a 16-day science mission which appears to have
exceeded all expectations for scientific data.
I would like to remind people of two things. First, space travel and
research is still a risky and technologically complex undertaking.
Things do not always go right. We are dealing with new fields of power
and speed. There are going to be times when things do not always go
right. So it would be completely inappropriate for us at the first sign
of serious trouble to cut and run.
Second, NASA emphasizes safety above all else. No one has ever
intentionally put our astronauts in unsafe or hazardous conditions.
Quite the opposite. I know from firsthand experience our astronauts are
trained to handle emergencies of all sorts that can be foreseen.
Some have suggested that before we send another astronaut to Mir,
NASA must certify to Congress that it has done everything possible to
make it safe. I find that an insult to NASA, because that has been
their primary objective all the way through the whole program. For
Congress to require that NASA had to certify it has done everything
possible to make it safe before we would have another astronaut sent to
Mir was about as unnecessary as anything I have seen since I have been
around here. I think such a certification would be an insult to the men
and women who work on this program every day. No one at NASA
intentionally ever takes risks with people's lives. But space flight is
risky, and we have to accept that.
I do not know whether people realize the speeds involved up there. I
meet with school groups quite often. I find them amazed when you say,
well, we have to travel nearly 18,000 miles an hour just to stay in
orbit up there. That is true. But that is such a large number, it does
not mean much until you ask the same students, ``What is 5 miles from
your school? Is the mall 5 miles from your home?'' It seems the mall
has an attraction for a lot of the young people these days. To make
that 5 miles trip in a spacecraft would take just 1 second. To stay in
orbit you are traveling about 4.8 miles per second--per second. And
when you come back in and start hitting the atmosphere again with the
spacecraft, there is tremendous heat buildup just from the friction of
the atmosphere, ionized layers out ahead that get up around 9,000 or
10,000 degrees Fahrenheit, and surface temperatures of, say, somewhere
around 3,000 degrees Fahrenheit.
We confront many challenges we have come to take for granted almost
that we can meet the challenge successfully. We have done it amazingly
successfully throughout the history of the space program. It has not
been perfect. So to think that it is going to be perfect is just a
wish.
Even if we were forced to curtail the Mir activity, we have already
learned a tremendous amount from the seven shuttle flights that have
been made to that station.
Let me just enumerate a few of the accomplishments.
Most importantly, we have conducted countless joint science
experiments in a variety of disciplines.
American astronauts have maintained a continuous presence in space
for nearly 470 days.
We have successfully conducted six shuttle-Mir docking missions, with
three more missions for the future.
Russian and American engineers, astronauts and cosmonauts, in
performing joint operations, have developed mutual understanding in
originally dissimilar design philosophies and established close rapport
between counterparts of the two different cultures. That is important
for the future.
We have learned to plan and execute a typical shuttle mission to a
space station.
We have verified and developed rendezvous and docking procedures.
We have conducted joint ground and mission control operations.
We have learned to transport and exchange supplies.
We have developed joint extra-vehicular activities.
We are testing schedules for long-duration Mir and short-duration
shuttle crew work rest cycles during the docked and undocked phases of
missions.
We are jointly resolving safety and acceptance testing differences.
And we are developing in-flight training protocols.
Most importantly, we are working together on joint research projects.
These accomplishments place us in an excellent position for
initiating and conducting the assembly and subsequent operation of the
international space station with reduced risk, with greater confidence
and reduced learning curve expenditures in time and costs. The only
other way to gain this experience would be to wait until assembly of
the ISS and then learn, and that is a little late.
Now all of this is leading up to construction and operation of the
international space station. Let me show just a couple of charts here.
This effort will be the largest peacetime international science
collaboration in the history of this world. These international
partners will include Canada, Japan, Russia, Britain, Italy, France,
Germany, Belgium, the Netherlands, Norway, Denmark, Spain, Sweden, and
Switzerland.
On-orbit weight will be 470 tons, and almost 20 percent of that, over
85 tons, of hardware has already been built.
This is an example of one piece of hardware now, one of the modules
right here. When built it will have some 43,000 cubic feet of
pressurized volume, which is the equivalent of a 747.
When you think about the number of scientific breakthroughs that can
come from such an orbiting laboratory as this, it is sort of mind
boggling.
I want to remind everyone of the critical importance of spreading the
word about the benefits of human space flight. I hope staffs listening
in the offices as well as Senators may go back to our communities in
our States and find new outlets or organizations which may not have
considered the significant impact which space research has had and
could have and will have on their lives. If we can just invigorate and
sustain such an effort I am very confident that the shuttle Mir and the
international space station will merely be steppingstones to a much
greater future.
I have asked NASA to put together, if they can, a compilation of the
of the scientific research projects that have gone on on each one of
those shuttle flights. I hope I can get that this evening so we can put
that in the Record tomorrow because I think it will show the diverse
nature of the scientific experiments, some of the breakthroughs that
have occurred because of those experiments, and I think that is the
best way to show what has happened in the shuttle program and the
potential that gives for the international space station.
We have some other pictures of the space station that is already put
together and is being worked on. This shows a technician working on
this particular hatch. This shows two of the modules here that are
already built, already tested out, and we have one unit that is
undergoing tests down at the cape right now.
This shows another view of what is being done. This is not something
that is theoretical into the future. It is being done right now.
This is a picture of some of the testing area where the hardware is
being checked out. The hardware is roughly, as I said, almost 20
percent complete right now. Now, that 470 tons will be the final size
of the vehicle once it is up there.
[[Page S7760]]
I see this as an extension of the best that our country has to offer
in the way of science and research and the questing nature of our
people that have given us a standard of civilization beyond anything
the world has ever seen. We have been a Nation that did not just say we
will live on the Atlantic shore on the coastal plain. We moved beyond
that to the Ohio River, to the Mississippi and on to the Plains.
I read into the Record last year, and I may bring it to the floor
again tomorrow, the statement by Daniel Webster, who for all his other
brilliance was a skeptic, sometimes, and had a rather myopic vision.
When they were considering buying lands west of the Mississippi from
Spain or Mexico, Daniel Webster was against it and he rose and said
words to the effect of ``What use can this area west of the Mississippi
be, this area of cactus and prairie dogs, of blowing sand, of mountains
with snow, impenetrable snow, to their base? Mr. President, I will not
vote 1 cent from the public Treasury to move the Pacific coast 1 inch
nearer Boston than it now is.''
That may show somewhat of a myopic view of even such a learned person
as Daniel Webster, but it does. And that is repeated somewhat today by
people who say, ``What is the possible value of this?'' The possible
value is clear in just a few of the things I have mentioned here today.
We have whole catalogs that have come out, things that have benefited
science, research, medicine, and engineering in this country, and they
are continuing. That is what this is about.
For the first time we will have some 15 nations involved in an
international space station, working together instead of preparing to
fight each other, working together using the best brains out of each of
those countries to do research that is of benefit to people all over
this Earth. That is the importance of it.
Some years ago when people would rise on this floor and say what
possible benefit can it be, we now have a good story to tell them. It
is a success story that every single American can be very, very proud
of.
I am happy to be supporting the station. I presume we will have some
amendments proposed on the floor that will change some of the program
and the way it is outlined. I hope we will not approve those. I think
the program has been revamped now. It is very well thought out. It is
being done at about the cheapest we can possibly do it and still keep
safety paramount, which is No. 1.
Mr. President, I ask unanimous consent to insert into the Record a
paper, ``Microgravity Research and Exploration'' provided by the NASA
Office of Life and Microgravity Sciences and Applications.
There being no objection, the material was ordered to be printed in
the Record, as follows:
Microgravity Research and Exploration
In the mid-20th Century human ventures into space have
ushered in a new era of exploration and defined a new field
of research using gravity as a variable. In turn, this
research has led to exciting discoveries on how profoundly
gravity affects all elements of life on this planet and
beyond. Over the years unexpected connections have been made
between the findings in microgravity and the many physical,
chemical and biological processes here on Earth, opening new
vistas for understanding ourselves and our world. These
findings have wide-ranging applications from medicine to
understanding weather patterns, contributing to economic
growth and vitality here on Earth.
These findings also serve as a sound foundation for future
human and robotic exploration and for settling new worlds in
the 21st Century. The International Space Station is the
first truly multinational effort by the people on Earth to
conduct a final rehearsal in low Earth orbit before spreading
into space on a new and exciting quest for the origins of
life.
Gravity is a force that has profoundly shaped the evolution
of all living things. Gravity and its effects drive or
constrain the fundamental physical, chemical, and biological
processes that surround us. It is the basic force against
which every living organism on Earth must work. Gravity gives
us our sense of balance, guides the development of our bones
and muscles, and challenges our hearts to pump blood against
its constant downward pull. Space flight gives humankind the
ability to control gravity as an experimental variable for
the first time in the history of science. With the control of
gravity, we gain a whole new perspective on the physical
world and on the world of living things.
historical perspectives
The human crew member has been an integral element of the
U.S. and Russian space programs since their inception. The
harsh environment of space has posed a number of critical
challenges for the protection of humans, planning for
missions, and the execution of experiments.1,2,3
The role of the human has grown as space missions and
programs have increased in duration and complexity.
Initially, the goal was to demonstrate man's ability to
survive in space. During the 1960s astronauts served mainly
as observers and backup operators to ground control
personnel. The Gemini and Vostok missions built on the
achievements of Mercury and Voskhod, and provided a technical
and biomedical foundation for the Apollo lunar landing and
Salyut space station programs. The Apollo missions required a
broad biomedical support program, including provisions for
in-flight illness. Like Gemini, the Apollo millions yielded
significant findings on human physiology in space, but few
insights into the effects of the space environment on
physical and chemical processes.

---------------------------------------------------------------------------
In the early 1970s Skylab provided the first opportunity to
study human adaption to microgravity over extended periods of
time, allowing researchers to identify those physiological
changes that are self-limiting. For the first time in the
history of space flight modest microgravity experiments were
conducted--the role of astronaut was expanded to that of
scientist/investigator. It is worth noting that during the
1970s many more experiments were executed in drop towers,
parabolic aircraft and suborbital robotic missions.
Since 1981 the reusable Space Shuttle has provided routine
access to Earth orbit, expanded the space program to include
investigators from industry and academia, and for the first
time in the history of experimentation provided an
exceptional platform for microgravity research. In 1994 an
agreement between NASA and the Russian Space Agency allowed
for the deployment of US research hardware on the Russian MIR
space station for experimentation by NASA astronauts. Similar
experiments to Space Shuttle missions are conducted on this
platform but in a more constrained fashion.
results to date
Since 1981 an unprecedented amount of scientific data has
been accumulated from space research that has revolutionized
our understanding of the nature and action of gravity on
physical and biological processes. To date the Space Shuttle
has flown approximately 720 days in space, of which 120 days
were dedicated to microgravity research. NASA astronauts have
flown 970 days on MIR with a total of 160 days dedicated to
microgravity experiments.
research with benefits to industrial processes and earth applications
Despite the relatively brief duration of actual research in
the life and physical sciences on orbit to date, numerous
applications have already been identified and acted on by the
private sector. These have been based on both scientific
findings as well as technological advances. Today, a
significant fraction of NASA's microgravity research program
is already conducted with substantial financial support from
other agencies and from industry, and we expect that
contribution to grow.
Scientists have successfully used the low gravity
environment of space to understand and control gravity's
influence on the formation of materials including metals,
semiconductors, polymers and glasses. For example, space
research has produced cadmium zinc telluride (CdZnTe)
crystals that have 50 times lower levels of a key defect than
the best commercially available crystals. These experiments
help researchers to verify mathematical models for
semiconductor crystal growth to improve semiconductor
fabrication on Earth. There have been many theories and
mathematical models developed to predict the formation and
development of dendrites, the tree-like structures that are
the building blocks of most metal products. On Earth,
gravity's effects limit the power of experiments to validate
these fundamental theories. The Isothermal Dendritic Growth
Experiment flown aboard the Space Shuttle has become the
scientific benchmark for testing our theoretical
understanding of metal formation.\4\
Another field in which microgravity research continues to
make major contributions is combustion science. Combustion is
a highly complex process involving many factors, such as: the
physical flow of fuel and oxygen; the chemical conversion
of fuel and oxygen into heat and chemical products and the
transfer of heat. In many cases, combustion processes are
so complex that scientists have difficulty developing
accurate, complete models for them. By significantly
reducing gravity's effects, scientists are studying subtle
aspects of combustion that are often hidden. Research to
date has demonstrated that gravity has a profound effect
on combustion phenomena, with microgravity conditions
leading to behaviors never before observed. Because
combustion is so widely used for energy production and
transportation, our growing knowledge of gravity's role in
combustion phenomena holds the promise of improving the
efficiency of a wide range of everyday technology, with
potentially far reaching economic effects. For example, a
patented ring flame stabilizer device has been developed
by Lawrence Berkeley National Laboratory
[[Page S7761]]
based on the results of microgravity combustion research.
This device--applicable to residential furnaces and water
heaters--reduces emissions of nitrous oxides by a factor
of five over existing devices, while increasing overall
efficiency by 2%.
Closely related to combustion science is fluid physics, a
field in which researchers study the behavior of liquids,
gases and mixtures. In microgravity, scientists observe
aspects of fluid behavior that are difficult or impossible to
understand in normal gravity. Microgravity enables scientists
to create physical models of important processes and make
observations that would be impossible on Earth. For example,
results from microgravity research have provided the only
controlled experimental observations of the convective
motions in physical models of planetary and stellar
atmospheres, laying a foundation for scientific understanding
of the nonlinear dynamics of planetary and stellar flows, and
giving us new insights into the dynamics of the sun and
gaseous planets.\5\ A new technique for stereo imaging
velocimetry to measure fluid flows in space experiments
developed by Lewis Research Center has found application in
the US industry, where it is being used to quantify fluid
flows in the steel casting process.
Use of the microgravity environment has allowed researchers
to design experiments that achieve a measurement accuracy not
possible in the gravity environment of Earth. Areas of
investigation include research on general relativity,
critical phenomena, laser cooling for ultra-precise
measurement of atomic electronic properties, as well as other
thermophysical measurements of interest in condensed-matter
physics. For example, space flight research has been used to
confirm with unprecedented accuracy the validity of a Nobel
prize-winning theory describing the conditions under which
matter will change between different states, such as from
liquid to gas or from conductor to superconductor.\6\
Research with Benefits to Health
Microgravity provides researchers with new tools to address
two fundamental issues in biotechnology: the growth of high-
quality crystals for X-ray diffraction studies of large
proteins, and the growth of three-dimensional tissue samples
in laboratory cultures. Gravity plays central roles in each
of these processes and NASA research is providing access to
new data and techniques to the broader biotechnology
community.
NASA's bioreactor, developed to simulate low gravity, has
proven dramatically successful as an advanced cell culturing
technology. This success has led to an extensive
collaboration with the National Institutes of Health (NIH).
Work with NASA bioreactors at the NIH has already produced
advanced cultures of lymph tissue for studying the
infectivity of HIV. Other areas of outstanding success
include cultures of cancer tumors and cartilage.\7\ Initial
results of tissue culture research on the MIR space station
are very positive and suggest the possibility of major
advances in tissue culturing once the International Space
Station becomes available.
Biotechnology researchers also use microgravity to produce
protein crystals for drug research that are superior to
crystals that can be grown on Earth. Already researchers have
produced crystal samples of proteins important to the study
of AIDS, emphysema, influenza, diabetes and other
diseases.\8\ Recently, researchers using space grown crystals
determined the highest resolution structure for insulin
published to date. By studying the structure and function of
insulin, scientists hope to produce improved drugs for
diabetics.
Life is, of course, dependent on many of the same physical
processes I have already discussed. Convection,
sedimentation, and buoyancy are features of complex, living
systems as well as nonliving systems. But life possesses
additional properties--such as adaptation to maintain
homeostasis, and evolutionary development in response to
environmental factors--that are also affected by gravity.
We are now demonstrating that microgravity can be used as a
model to study some aspects of the aging process here on
Earth. Indeed, astronauts experience bone and muscle loss,
inability to maintain balance, posture, gait, and blood
pressure, and changes in the general metabolism that mimic
some of the symptoms of aging. Thus, microgravity research
offers an unusual opportunity for us to study in a laboratory
setting this natural phenomena of the life cycle. The
symptoms caused by space flight reverse themselves on return
to normal gravity, presenting additional opportunities for
insight into the aging process.
The accumulated data from experiments in the physical
sciences has formed the basis for a multidisciplinary
investigation of biological phenomena using the findings from
fluid physics research. As a result, we are obtaining
explanations for complex biological behavior at the cellular
and molecular levels. We are able to formulate a new set of
hypotheses regarding the behavior of complex ecological
systems in relation to multigenerational adaptive responses
to the pervasive effects of gravity.
We have found that even the tiny single-celled organisms
suspended in water are equipped to respond to gravity. We
have used the low gravity environment of space to research
and establish the mechanisms individual cells use to
translate physical force, like acceleration due to gravity,
into chemical signals that drive adaptation and response. We
have begun work to explore the process by which plants
respond to gravity to produce lignin, the primary component
of wood. We look forward to exploring the role that gravity
has played on Earth, and possibly in other places, in the
genesis and evolution of life. If a planetary gravitational
environment necessary for the creation or continued existence
of life, how would living systems evolve in a different
gravitational environment?
research with benefits for space flight
Research into the effects of gravity on fundamental
physical, chemical, and biological processes is increasingly
serving as the underpinning for our understanding of how to
live and work in space. Space flight induces changes in
virtually all body systems. Most appear to be benign
adaptations to weightlessness, but if unchecked some
physiological changes could become life threatening. It seems
today that exposure to the low gravity environment produces a
disassociation between the chronological and physiological
ages. Thus, our task is to bridge this time gap by developing
countermeasures such as exercise and pharmacokinetics.
The time course and extent of physiological changes in
astronauts must be characterized, and appropriate
countermeasures (compatible with the spacecraft design)
developed for long-duration orbital and interplanetary space
missions. This research promises to improve our general
understanding of human physiology and a number of medical
conditions. Similarly, the countermeasures that we devise may
benefit health care on Earth.
To illustrate the breadth of the challenges we face,
consider the digestive system. Relatively little work has
been done on the effects of low gravity on the digestion,
absorption and transport of drugs and nutrients in space. You
might think that in a confined space like the human bowel
there would be little role for gravity to play. But keep in
mind that it is gravity that causes bubbles of gas to rise to
the surface of a liquid and dispersed particles to settle
out. We know that astronauts do not suffer from malnutrition,
but how are digestion and pharmacokinetics affected?
Challenged by the need to monitor the health status and
deliver health care services to astronauts in ever more
remote and hostile environments, NASA is at the cutting edge
of medical technology requiring autonomy. Space programs have
pioneered the use of telecommunications, computer, and
microelectronic and nanoelectronic technologies in health
care. While critical for space flight and exploration, these
technologies also yield considerable benefit for medical care
here on Earth. The highly successful Spacebridge to Russia
program--a joint effort between NASA and the Russian Space
Agency--is an Internet-based telemedicine testbed that links
academic and clinical sites in the US and Russia for clinical
consultations and medical education. A predecessor project--
Spacebridge to Armenia--was used to provide medical
consultation services during the recovery from the Armenian
earthquake in 1988. Pilot projects in telemedicine technology
have also supported health care delivery in a wide variety of
remote locations.
NASA has developed a range of technologies in medical
informatics, sensors, diagnostic techniques, decision support
systems, image compression, and advanced training to support
health care delivery in space. These technologies include
compact, solid state sensors that permit non-invasive
monitoring of crew health and the space-craft environment.
NASA's Ames Research Center is adapting technology,
originally developed for space-related scientific
visualization, to stimulate complex surgery. This
application enables surgeons to reconstruct a patient's
face and skull from computerized tomographic (CT) scans,
allowing doctors to virtually manipulate the bone tissue
and visualize possible surgical procedures. Marshall Space
Flight Center has worked cooperatively with industry to
develop a Sensing and Force-Reflection Exoskeleton
(SAFiRE) that senses hand and finger motion as human
operator input and provides force-reflective feedback to
the operator for both telerobotic and virtual environment
applications. The SAFiRE project's technology base could
be used to develop a biomechanically sound resistance
exercise system.
future research
Recent discoveries of life's adaptation to very extreme
environments and the potential for past or even present
existence of life on Mars or elsewhere in the Universe have
raised a range of compelling questions. Life's complex
processes are ubiquitous on Earth. Are they present on other
worlds as well? What role has gravity itself played in the
genesis and subsequent evolution of life on this planet and
elsewhere? Humanity's fascination with life and the physical
world propels our interest in the exploration of space.
As demonstrated by the success of the Mars Pathfinder
mission, NASA has embarked on a promising path of
technological innovation that is creating a ``virtual'' human
presence on other worlds. Future missions of exploration will
require crew members to live and work productively for
extended periods in space and on planetary surfaces. As in
the past, key biomedical, life support and human factors
questions must be answered to ensure crew health, well-being,
and productivity. To address these
[[Page S7762]]
challenges, NASA will apply innovative technology to the
challenges of robotic and human space exploration, ranging
from advances in telemedicine, telepresence, and life support
to in situ materials utilization, nanotechnology, and
bionics. In the coming decades, fundamental and applied
research in gravity's effects will lay the foundation for
humans to develop and use space, and to expand outward on
missions of exploration.
protecting crew health
Our first priority is ensuring the health and safety of our
crews. Long duration flights have demonstrated that it is
possible to survive extended term exposure to low gravity.
Yet, as I have described above, we must not forget that
adjusting to microgravity and then back to normal gravity is
a traumatic experience for the body. Many of our intuitive
theories for explaining these processes have already failed
in the light of hard data. Even some of our long-held
theories about the gravity dependence of physiological
processes for humans on Earth have been proven false by space
research. We must remain cautious in drawing general
conclusions from the small sample sizes currently available
and we must develop a rigorous understanding of the
mechanisms behind adaptation to microgravity as well as the
dose-response relationship. If we do a thorough scientific
job of understanding the mechanisms and dose-response
relationships of adaptation of low gravity we will create a
new storehouse of knowledge with innumerable applications to
Earth-based medical care.
telescience and Telemedicine
In the next few years, the International Space Station will
serve as a platform for developing and testing systems that
will permit future space explorers to respond autonomously to
a wide variety of ongoing and emergency health care issues.
Medical monitoring will take advantage of noninvasive
microminiaturized sensors and advanced wireless
communications technology as well as next generation systems
for displaying and integrating the data stream. Emphasis on
portability and noninvasiveness of medical monitoring will
also pay large dividends by reducing the need for storage and
transportation of specimens.
advanced life support technology
Future exploration missions will rely on advanced,
lightweight, closed-loop life support systems to sustain life
in the hostile space environment. Research on advanced life
support systems include both ground based and flight
components. We have already begun a series of closed tests
using crews of up to four people in ground based facilities
at the Johnson Space Center. Flight testing and validation
for life support systems will take place on the International
Space Station. Our goal is to demonstrate advanced life
support system on ISS that would be suitable for a Mars
transit vehicle by 2004, and validate system performance by
2008. Space Station environmental monitoring systems will
incorporate new miniaturized sensor technology requiring
greatly reduced resources to operate.
physical sciences
We cannot overlook the vital role that fundamental research
in the physical sciences will play in the future of
exploration. Materials science research will explore advanced
radiation shielding materials vital to long-duration space
missions. Research in the behavior of fluids in low gravity
will help the designers of future space systems to move from
an empirical approach to approaches based on valid
mathematical models for such vital systems as thermal
control, fuel storage, and delivery, and life support
systems. Research on combustion phenomena will contribute to
improved technology for detecting and extinguishing fires in
spacecraft.
Fundamental physical research is also required to lay the
foundation for efficient and safe operations on the surfaces
of other bodies in the solar system. We must understand the
behavior of materials in the novel environments found on
other solar system bodies if we are to design efficient
systems for in situ resource utilization for fuel, life
support, radiation protection, fire detection, and
construction. Microgravity researchers are now participating
in planning for robotic missions to Mars in 2001 and 2003
that will include experiments designed to explore these
issues.
The quest for understanding in space is a voyage into the
unknown. We cannot accurately predict what we will find, or
what we will produce. But if we are to control the risks of
human space flight and extract the benefits of space
development for future generations, we must continue our
efforts to reduce our ignorance. We must focus our research
both in the life sciences and the physical sciences, using
robotic missions in parallel with crewed missions to reduce
the risks of human space flight. As a result, we will extend
human virtual and physical presence further into the solar
system, paving the way for broad commercial and scientific
development in space. Ultimately, we will learn to send
astronauts on long duration missions of exploration. Their
work will serve to extend our research to new worlds, and
possibly to new forms of life.

Ms. MIKULSKI. Mr. President, as the ranking member of the VA-HUD
Committee, of which NASA is one of our key agencies, I thank the
Senator from Ohio for his detailed speech about what NASA is doing, not
only today, but what it will do tomorrow. I believe the Senator, by
talking about the exciting projects that we have, many of which have
originated from the work at the Johnson space station, in the Presiding
Officer's home State, the work in the area of health care. I visited
these programs, know the merit they have, particularly in cancer
research, tumor research, the issues outlined by the Senator from Ohio.
Also, in 1992, NASA and NIH signed a joint memorandum of agreement on
how they can work together to maximize the research being done by the
space agency, along with NIH, on issues related particularly to cancer
and to issues related to women's health. Issues like osteoporosis, the
same kinds of problems that the astronauts face being in orbit, are
what many face, particularly we women on Earth. We lose bone density.
There has been a lot of joint effort and a lot of joint agreement. I
think the Senator made a very valuable contribution and I thank him for
his remarks.
Sometimes for those of us who seek funding for NASA, it sounds self-
serving, that we would tout, pull out an item or two. But when Senator
John Glenn, an astronaut-Senator, speaks to it, I think the whole world
listens.
We thank him for his comments and his contribution to the Senate and
to the American space program.
I yield the floor.
Mr. BOND. I join my distinguished colleague from Maryland in thanking
our friend from Ohio. No one in this body speaks with more knowledge
and expertise on space issues than Senator John Glenn. To hear him talk
about the exciting things that are happening in space, science and
medical advances, it truly is remarkable. It gives one a sense of what
we can accomplish with the investments we make.
This is extremely helpful, as we go into the debate, because these
are very tight budget times. We have taken a step of assuring that
money is available for space, for investment in our future by the
exploration not just of space but of the scientific discoveries that
can come from utilizing the space station.
I thank him first as one who is interested in science. I envy his
background and his knowledge. I appreciate very much his description of
the exciting things that can come from space exploration, not just for
those of us who are worrying about the funny-named rocks on Mars but
those who want to see concrete and specific medical advances here
today.
Mr. GLENN. We have in room S. 211, for the information of Senators or
their staffs, a panoramic view that has been put together by NASA of
Mars as taken from the Pathfinder. A full-sized model is out there for
people to look at. It is intriguing. It is so tiny you cannot believe
it is sending all this information back to us on Earth.
We invite staffs or Senators when they come over for a vote which
starts at 5:15 to stop in and look at it. It is very worthwhile and
gives a different concept than just seeing the pictures on TV.
I yield the floor.
Mr. BOND. I had my picture taken with the Sojourner. I thought it was
quite coincidental that the Sojourner model showed up today. Timing is
everything.
I urge my colleagues who are interested in this space exploration to
look at the panoramic view to see how the Sojourner operates.
I see my colleague from Texas is anxious to speak. I yield the floor.
The PRESIDING OFFICER (Mr. DeWine). The Senator from Texas.
Mrs. HUTCHISON. Mr. President, I want to say it was a pleasure for me
to hear the Senator from Ohio talk about this very important subject. I
am
[[Page S7763]]
proud the Senator from Ohio was once my constituent when he made the
historic trip into space--that was really the beginning of our space
program--and made us all so proud that we really could conquer space.
What we have learned and what we have done for quality of life and for
health research since his first foray into space has been, perhaps,
more than even he could have dreamed would happen.
I am very proud he is a supporter of the space station and the NASA
Program and knows that what he did in the beginning is certainly not
the end and certainly, I hope, we can continue the legacy that he has
left for us.
Mr. BOND. Mr. President, I believe the leader is going to be here
shortly to discuss the voting schedule for tonight. I know votes were
scheduled to begin at 5:15, but pending the arrival of the majority
leader, I suggest the absence of a quorum.
The PRESIDING OFFICER. The clerk will call the roll.
The assistant legislative clerk proceeded to call the roll.
Mr. STEVENS. Mr. President, I ask unanimous consent that the order
for the quorum call be rescinded.
The PRESIDING OFFICER. Without objection, it is so ordered.
