; (4) to the maximum extent practicable, a national microgravity laboratory in space should be maintained in cooperation with international space partners; and (5) NASA should continue to support fundamental science research on future platforms in low-Earth orbit and cislunar space, orbital and suborbital flights, drop towers, and other microgravity testing environments. (b) Report The Administrator, in coordination with the National Space Council and other Federal agencies as the Administrator considers appropriate, shall issue a report detailing the feasibility of establishing a microgravity national laboratory federally funded research and development center to carry out activities relating to the study and use of in-space conditions. II SAFETY AND TRANSPARENCY 201. Crew transportation safety (a) Sense of congress It is the sense of Congress that— (1) ensuring the safety of American astronauts is the top priority of NASA’s human spaceflight program; (2) in efforts to meet deadlines to return humans to the Moon, NASA should take all steps necessary to mitigate any and all risk to crew; and (3) it is the role of Congress to exercise prudence in the use of taxpayer dollars and ensure transparency to the taxpayer to the greatest extent possible. (b) In general To ensure that NASA’s human exploration systems comply with the direction in this Act to have a shared safety standard that is consistent across all elements of the architecture, the Administrator shall— (1) implement a program to ensure that best practices, lessons learned and other information is shared across all elements of the human exploration program, including public-private partnerships and commercial service procurement
