; and (3) an integrated, master plan for the development of required capabilities for the human mission to Mars. (d) Systems Engineering and Integration The Director of the Moon to Mars Program Office shall appoint a Systems Engineering and Integration Manager to manage the systems engineering and integration activities of the Moon to Mars Program. (e) Special Hiring Authorities The Administrator shall propose to Congress any special hiring authorities that the Administrator determines are needed to ensure that personnel with the requisite skills and experience are available to the Program Office. (f) Program Elements The Moon to Mars Program shall consist of the following: (1) A Gateway to Mars in cis-lunar space or at a Lagrangian point for the purpose of reducing the risks of the capabilities in paragraph (3) and serving as a testbed for the systems and operational techniques needed to transport crews to, from, and during operations in Mars orbit or on the surface of Mars. The Gateway to Mars shall be developed to operate autonomously and to be crew-tended, as needed, on an intermittent basis. The Gateway to Mars shall be open and available for international participation and use. (2) A Lunar Precursor Initiative (LPI) for the purpose of gaining and demonstrating the operational experience and systems needed to enable crewed transport to and from the surface of Mars, as well as for limited operations and habitation on Mars. (3) A Mars Enabling Technology Initiative (METI) for the purpose of developing and testing the technologies and capabilities needed for a human missions to Mars. Mars-enabling technologies and capabilities to be demonstrated shall include— (A) Mars entry, descent, and landing systems; (B) radiation safety; (C) in-space power and propulsion, including nuclear thermal propulsion; (D) Mars transport vehicle; (E) planetary ascent propulsion; (F) environmental control and life support systems; (G) Mars habitats; (H) extravehicular activity suits
