The CAESAR (Comet Astrobiology Exploration SAmple Return) mission is one of two New Frontiers missions selected for Phase A. CAESAR will acquire a sample from the nucleus of comet Churyumov-Gerasimenko, returning it safely to Earth.
Comets are made up of materials from ancient stars, interstellar clouds, and the birth of our solar system.
The CAESAR sample will reveal how these materials contributed to the early Earth, including the origins of the Earth's oceans, and of life
The CAESAR mission seeks to return this sample from 67P/Churyumov-Gerasimenko, a comet that was successfully explored by the European Space Agency’s Rosettaspacecraft, to determine its origin and history.
• PI Steve Squyres of Cornell University • CAESAR would be managed by NASA’s Goddard Space Flight Center
