We are in an exciting era that diverse samples are being returned by multiple missions. A geological sampling of Mars will be performed by the Mars 2020 mission and returned in the near future. Two missions are returning or have already successfully returned samples from the surface of asteroids. These samples greatly expand the collection of returned extraterrestrial samples, which offer scientists the best opportunity to understand the origin, evolution, and processes of the solar system.

This opportunity is to join Dr. Yang Liu at JPL to study surface and interior processes of the parent bodies from which samples were collected and returned. Example science areas include but are not limited to volatiles, mineralogy, petrology, and geochemistry of these returned materials. The successful candidate will be expected to identify and carry out an innovative research program in one or more of these science areas, or that could stimulate new research areas.
