MoonRise is a proposed mission to the Moon as part of NASA's New Frontiers program mission 4. If developed and launched, it would focus on the giant South Pole–Aitken basin (SPA basin) on the far side of the Moon between the Moon's South Pole and Aitken Crater, 16° south of the Moon's equator. This basin measures nearly 2,500 kilometres (1,600 mi) in diameter and 12 kilometres (7.5 mi) in depth. This region is the oldest, deepest, observable impact basin on the Moon and provides a window into the deep crust of the Moon and its history as a result. The basin is also among the largest recognized impact structures in the Solar System.[1]

MoonRise was not selected for the third New Frontiers program mission 3, losing out to the OSIRIS-REx asteroid sample return mission,[2] but it is a 2017 contender for the New Frontiers program mission 4.[3] If selected, it would be NASA's first unmanned sample-return mission from another planetary body.[4]

Science objectives[edit]

MoonRise has the following objectives:[1]

  • Determine the impact chronology of the SPA basin
  • Investigate processes associated with the formation of large impact basins
  • Investigate the materials excavated from the deeper crust, and possibly the mantle, of the Moon within the SPA basin
  • Determine rock types, distribution of thorium, and implications for the Moon's thermal evolution
  • Sample and analyze basaltic rock and volcanic glass, which record the composition and chemical evolution of the Moon's far-side mantle beneath the SPA basin

Future prospects[edit]

MoonRise received Phase A funding out of the New Frontiers program.[5] The study was on of three concepts to get US$3.3 million funding in 2010 to further developed the mission for the final selection, which was a US$650 million mission to launch in the late 2010s.[4] The three semi-finalists were MoonRise, the OSIRIS-REx sample return mission, and the Venus In Situ Explorer mission.[4]

Although MoonRise was passed over in favor of OSIRIS-REx in the 2011 selection, a South Pole–Aitken basin sample return mission remains part of the 2013-2022 Planetary Science Decadal Survey's recommendation for potential New Frontiers missions,[6] and NASA's Planetary Science Division has expressed support for the Decadal Survey's recommendations.[7]
