Crewed Lunar Landing Missions In order to minimize the time required for the Lunar Precursor Initiative phase of the Moon to Mars Program, NASA shall plan for and implement measures to enable a crewed lunar landing mission rate of at least two per year after the initial crewed lunar landing has been achieved. (g) Lunar Lander Management The Moon to Mars Program Office shall manage the overall development of the Human Lunar Landing System, with the Johnson Space Center responsible for the crew-related elements, vehicle structure, and Human Lunar Landing System integration and the Marshall Space Flight Center responsible for the Lander propulsion systems. (h) Ground and Flight Test Activities The Moon to Mars Program shall maintain a robust series of ground and flight test activities for each element of the Program, including at least one crewed flight test of each crewed system design prior to its use on a human lunar landing system or Mars mission. (i) Mars Landing and Ascent System Designs To the extent funding permits, the Administrator shall maintain two competing integrated crewed Mars landing/ascent system design concepts through the critical design review milestone, at which point the Administrator shall make a selection of the system to be utilized in the first human Mars landing mission. 206. Noncritical path activities (a) Lunar Outpost Any establishment of a continuously crewed lunar outpost or research station shall not be considered an element of the Moon to Mars Program and shall be budgeted separately from the Moon to Mars Program. (b) Other Crewed Activities Crewed activities on or around the surface of the Moon that do not contribute to the goal of landing humans on Mars in as sustainable manner as practical shall not be included in the Moon to Mars Program and shall be budgeted separately from the Moon to Mars Program. (c) Lunar In-Situ Resource Utilization Lunar in-situ resource utilization shall not be considered as risk reduction for the initial crewed missions to orbit and land on Mars. Any
