Aeolis Palus Aeolis Palus Aeolis Palus is a plain between the northern wall of Gale crater and the northern foothills of Aeolis Mons (Mount Sharp) on Mars. It is located at . The NASA Mars Science Laboratory mission landed the "Curiosity" rover on Aeolis Palus in August 2012. "Curiosity" spent two (Earth) years exploring the plain as it drove towards Aeolis Mons. The rover left the plain in September 2014 when it reached the mountain's foothills. On August 5, 2012, at 10:32 p.m. PDT/mission time (August 6, 2012 at 5:32 UTC), mission control at JPL received a signal from the NASA "Curiosity"
Mars sample-return mission request of NASA and the NSF, declared a MSR campaign its highest priority Flagship Mission for that period. In particular, it endorsed the proposed Mars Astrobiology Explorer-Cacher (MAX-C) mission in a "descoped" (less ambitious) form, although this mission plan was officially cancelled in April 2011. In September 2012, the United States' Mars Program Planning Group endorsed a sample-return after evaluating long-term Mars' plans. The key mission requirement for the planned Mars 2020 rover is that it must help prepare NASA for its MSR campaign. which is needed before any crewed mission takes place. Such effort would require three additional vehicles:
