         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, Biological and Physical Sciences, 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, and
            procurement.  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, Transformative Aeronautics Concepts, and Aerosciences Evaluation
            and Test Capabilities. Full costs of these programs include all labor, travel, procurement, test, and fabrication costs associated
            with the research, development, operations, and other general and administrative activities required to execute the programs.
            Performance goals associated with these activities are addressed in NASA's detailed budget request.

         This appropriation provides for the costs associated with research and development in space technologies serving multiple
            customers within NASA, private industry, academia, and other government agencies. 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 the Space Technology account enhance research and development at NASA to contribute to the United States'
            leadership in space technology and enable human and robotic exploration of the Moon, Mars, and Beyond. The Space 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.

         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 Surface Capabilities, the Human Landing System, and the Human Research
            Program.

         Safety, Security, and Mission Services (SSMS) manages agency-wide mission support functions and some of NASA's 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.  SSMS programs, projects and activities fall under the two Themes described below.
         
          Mission Services and Capabilities (MSaC) delivers enterprise solutions through three programs: Information Technology; Mission
            Enabling Services; and Infrastructure and Technical Capabilities. These programs meet workforce, infrastructure, information
            technology and business operations requirements necessary to enable NASA's mission.  MSaC ensures that critical Agency operations
            across all NASA Centers are effective, efficient, safe, and meet statutory, regulatory, and fiduciary responsibilities.
         
          
         Engineering, Safety, and Operations (ESO) provides for the ongoing management of NASA Headquarters, nine Centers, and component
            facilities.  It funds medical and engineering technical authorities and contributes to the reduction of program risks by ensuring
            that technical skills and assets are ready and available to meet program and project requirements. ESO ensures that Center
            practices are technically and scientifically sound and that specialized infrastructure at the Centers is safe and reliable.

         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 associated with
            the research, development, operations, and other general and administrative activities conducted by the programs within this
            account. Major themes within the Space 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 activities unique to the on-orbit attributes of the facility.
         
         The Space Transportation theme is comprised of the Commercial Crew Program and Crew and Cargo Program, which transport U.S.
            astronauts and cargo safely back and forth to the ISS and, in the future, to other orbital platforms and destinations. Maintaining
            the ISS requires a fleet of vehicles and launch locations to transport astronauts, science experiments, 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 services to the ISS through contracts with Northrop Grumman, SpaceX,
            and Sierra Nevada and purchases crew transportation services from Boeing and SpaceX. Payments to develop and test commercial
            crew vehicles, and for initial Post Certification Missions 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 supports 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 and on supporting the growth of private sector
            activity in LEO.

         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 customer service 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 with complete redundancy
            in the electrical distribution system from the national grid to the rack level.

            Administration in this Act 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 funds transferred to "Construction
            and Environmental Compliance and Restoration" for construction activities shall not increase that account 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.
      Not to exceed 5 percent of any appropriation provided for the National Aeronautics and Space Administration under previous
            appropriations Acts that remains available for obligation or expenditure in fiscal year 2022 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 transfer pursuant to this provision shall retain its original
            availability and 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 the National Aeronautics and Space Administration 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.
      
      
      Not more than 20 percent or  $25,000,000, whichever is less, of the amounts made available in the current-year CECR appropriation may be applied to CECR projects
            funded under previous years' CECR appropriation Acts. Use of current-year funds under 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.
