The Comet Astrobiology Exploration Sample Return (CAESAR) mission was selected by the NASA New Frontiers Program for Phase A study in December 2017. CAESAR will acquire and return to Earth for laboratory analysis a minimum of 80 grams of surface material from the nucleus of comet 67P/Churyumov-Gerasimenko (67P). CAESAR will characterize the surface region sampled, preserve the collected sample in a pristine state, and return evolved volatiles by capturing them in a separate gas reservoir. NASA Goddard Space Flight Center provides project management, systems engineering, safety and mission assurance, contamination control, mission operations, and many other important functions. Northrop Grumman Information Systems (formerly Orbital ATK) will build the spacecraft, based on Dawn mission heritage, which like CAESAR, uses solar electric propulsion.
