         The Science appropriation provides for NASA's science mission, which is comprised of the agency's Earth and space science
            programs: Earth Science, Planetary Science, Heliophysics, the James Webb Space Telescope, and Astrophysics. These programs,
            which are managed by the Science Mission Directorate, focus on three interdisciplinary objectives: discovering the secrets
            of the Universe; searching for life in the Solar System and beyond; and safeguarding and improving life on Earth. These objectives
            include research concerning the global Earth system; other planets in the solar system and around other stars; the connections
            among the Sun, Earth, and heliosphere; and the origin and evolution of planetary systems, the galaxy, and the universe, including
            the origin and distribution of life in the universe. Program objectives are pursued through robotic flight missions, ground-based
            scientific research and data analysis, and the development of new technologies for future missions. Additionally, the Budget
            funds within Science a lunar robotic exploration program that will support innovative approaches to achieving human and science
            exploration goals.
         
         The Science appropriation provides for all of the research, development, operations, salaries and related expenses, and other
            general and administrative activities required to execute the programs within this account. Costs include labor, travel, procurement,
            and test and fabrication costs. Performance goals associated with these activities are addressed in NASA's detailed budget
            request.

         This appropriation provides for the full costs associated with NASA's Aeronautics Research mission, which aims to expand the
            boundaries of aeronautical knowledge for the benefit of the nation and the broad aeronautics community. The mission is managed
            by NASA's Aeronautics Research Mission Directorate, and consists of the following integrated research programs: Airspace Operations
            and Safety, Advanced Air Vehicles, Integrated Aviation Systems, and Transformative Aeronautics Concepts. Full costs of these
            programs cover all of the research; development; operations; salaries and related expenses; and other general and administrative
            activities required to execute the programs. Costs include labor, travel, procurement, test, and fabrication costs. Performance
            goals associated with these activities are addressed in NASA's detailed budget request.

         The FY 2020 President's Budget renames the Space Technology account as Exploration Technology to better reflect the new focus
            of this account on supporting the Exploration Campaign. 
         
         The Exploration Technology appropriation provides for the costs associated with the research and technology development needed
            for space exploration. The full costs provide for all of the research, development, operations, salaries and related expenses,
            and other general and administrative activities required to execute the programs within this account. Costs include labor,
            travel, procurement, and those associated with fabrication, tests and flight demonstrations.
         
         The programs within Exploration Technology enable and reduce barriers to new exploration missions by drawing on talent from
            the NASA workforce, academia, small businesses and the broader space enterprise to deliver innovative solutions that dramatically
            improve technological capabilities for NASA and the Nation. The Exploration Technology appropriation funds several programs:
            Small Business Innovative Research (SBIR), Small Business Technology Transfer (STTR), Early Stage Innovation & Partnerships,
            Technology Maturation, and Technology Demonstrations. Performance goals associated with these activities are addressed in
            NASA's detailed budget request.

         The FY 2020 President's Budget has renamed the Exploration account Deep Space Exploration Systems to better reflect the activities
            in the account.
         
         This appropriation provides for costs associated with the development of systems and capabilities required for human exploration
            of space. The capabilities include launch and crew vehicles for missions beyond low Earth orbit; providing integrated systems
            to keep astronauts safe, healthy, and functional during deep space missions; and advancing the tools to increase exploration
            capabilities and reduce the launch mass and cost of deep space missions. The full costs provide for the research, development,
            operations, salaries and related expenses, and other general and administrative activities required to execute the programs
            within this account. Costs include labor, travel, procurement, test, and fabrication costs. Performance goals associated with
            these activities are addressed in NASA's detailed budget request.
         
         NASA's human deep space exploration programs include the Space Launch System, Orion, Exploration Ground Systems under the
            Exploration Systems Development theme, as well as the Exploration Research and Development theme which consists of Advanced
            Exploration Systems, the Gateway, Advanced Cislunar and Space Capabilities, and the Human Research Program.

         The Budget proposes to terminate funding for the Office of Science, Technology, Engineering, and Mathematics (STEM) Engagement's
            portfolio of programs and projects. Unobligated balances previously appropriated under this heading or the heading "Education"
            may be used to support close-out costs. Moving forward, a small team at NASA headquarters funded out of Agency Management
            and Operations will be accountable for strategic direction and coordination of the agency's STEM engagement efforts.

         Safety, Security, and Mission Services (SSMS) manages agency-wide mission support functions and some of NASA's unique research
            facilities.
         
         This appropriation provides for the operations and maintenance, salaries and related expenses, and other general and administrative
            activities that support all NASA's missions.
         
         Under SSMS, Center Management and Operations includes the basic costs to manage and operate each of the nine NASA field centers
            and to maintain the technical capabilities required to support the Agency's Mission. The SSMS budget is not directly allocated
            or aligned to specific program or project requirements, but is centralized for efficient and effective administration and
            operation of the NASA Centers.
         
         Under SSMS, Agency Management and Operations provides for the management and oversight of corporate programs, the performance
            of agency-wide activities and functions, and the maintenance of unique research capabilities and facilities. Responsibilities
            include budget formulation and execution; establishment of management policies, procedures, and performance criteria; evaluation
            of progress; and coordination and integration of the Agency's activities.

         This appropriation provides for the full costs associated with human-related Low Earth Orbit (LEO) and spaceflight operations
            activities of the agency. The full costs include all labor, travel, procurement, test, and fabrication costs to execute these
            programs, which provide for all of the research, development, operations, salaries and related expenses, and other general
            and administrative activities supporting the programs within this account. Major themes within the LEO and Spaceflight Operations
            account include the International Space Station, Space Transportation, Space and Flight Support, and Commercial LEO Development.
            Performance goals associated with these activities are addressed in NASA's detailed budget request.
         
         The International Space Station (ISS) is a complex of research laboratories in LEO where America and its international partners,
            including Russia, Canada, Europe, and Japan, conduct unique scientific and technological investigations in a microgravity
            environment. The objective of the International Space Station is to support human space exploration and conduct science experiments
            and technology development unique to the on-orbit attributes of the facility.
         
         Space Transportation's objective is to transport U.S. astronauts and cargo safely back and forth to the ISS and, in the future,
            to other orbital platforms and destinations. This theme includes the Commercial Crew Program and Crew and Cargo Program. Maintaining
            the ISS requires a fleet of vehicles and launch locations to transport astronauts, science experiments, critical supplies,
            maintenance hardware, and propellant to the ISS, and to dispose of waste generated on the ISS. The Commercial Crew Program
            partners with two U.S. companies, SpaceX and Boeing, to develop and operate safe, reliable, and affordable crew transportation
            to LEO. The Crew and Cargo Program purchases cargo transportation to the ISS under commercial resupply services contracts
            with Northrop Grumman, SpaceX, and Sierra Nevada and purchases crew transportation from Boeing, and SpaceX. Payments to develop
            and test commercial crew vehicles, and for initial Post Certification Missions (PCMs) for each provider are funded by the
            Commercial Crew Program, whereas subsequent payments for operational commercial crew missions are funded by the Crew and Cargo
            Program.
         
         Space and Flight Support is comprised of multiple programs that provide ongoing support for a wide range of services required
            for safe and successful space mission operations. These programs include Space Communications and Navigation, Communications
            Services Program, Human Space Flight Operations, Launch Services, and Rocket Propulsion Testing. Services are provided to
            a wide range of customers including NASA, other U.S. Federal agencies, foreign governments, and industry partners.
         
         Commercial LEO Development will support efforts to expand commercial activities in LEO, with a focus on enabling, developing,
            and deploying commercial platforms that can be used by NASA and other customers.

         The Working Capital Fund provides goods and services on a reimbursable basis. The Fund finances four program activities. The
            first is the Solutions for Enterprise-wide Procurement program, which finances, on an agency-wide basis, scientific and engineering
            workstation procurement. The second program is the Information Technology Infrastructure Integration Program which consolidates
            and centralizes management of NASA information technology services in the areas of Tier 1 service desk and ordering, web services
            and technologies, enterprise business and management applications, integrated network/communications services, end user services,
            and data center services. The third program, NASA's Shared Services Center, performs selected financial management, human
            resources, information technology, and procurement services for NASA Headquarters and Centers. The last program, the National
            Center for Critical Information Processing and Storage, provides federal customers collocation services at a Tier III level
            with complete redundancy in the electrical distribution system from the national grid to the rack level.

            is claimed or the offer is withdrawn.
      Not to exceed 10 percent of any appropriation made available for the current fiscal year for the National Aeronautics and Space Administration
            in this Act, or provided for the National Aeronautics and Space Administration under previous appropriations Acts that remain
            available for obligation or expenditure in fiscal year 2020, may be transferred between such appropriations, but no such appropriation, except as otherwise specifically provided, shall
            be increased by more than 10 percent by any such transfers. Any such funds transferred to "Construction and Environmental
            Compliance and Restoration" for construction activities shall not increase that appropriation by more than 20 percent. Balances
            so transferred shall be merged with and available for the same purposes and the same time period as the appropriations to
            which transferred. Any transfer pursuant to this provision shall be treated as a reprogramming of funds under section 504
            of this Act and shall not be available for obligation except in compliance with the procedures set forth in that section.
      The spending plan required by this Act shall be provided by NASA at the theme and program level. The spending plan, as well
            as any subsequent change of an amount established in that spending plan that meets the notification requirements of section
            504 of this Act, shall be treated as a reprogramming under section 504 of this Act and shall not be available for obligation
            or expenditure except in compliance with the procedures set forth in that section.
