|Alternate Names||Comet Astrobiology Exploration SAmple Return|
The CAESAR (Comet Astrobiology Exploration SAmple Return) mission is a comet sample return mission concept selected in December 2017 for further development. The spacecraft would return a sample from 67P/Churyumov-Gerasimenko, a comet that was successfully explored by the European Space Agency’s Rosetta spacecraft, to determine its origin and history.
The CAESAR and Dragonfly missions will receive funding through the end of 2018 to further develop and mature their concepts. NASA plans to select one of these investigations in the spring of 2019 to continue on to subsequent mission phases.
Launch Vehicle: TBD
Spacecraft Mass: TBD
