Melissa Trainer is an American planetary scientist who works as a research scientist at the Jet Propulsion Laboratory (JPL), a division of the California Institute of Technology that manages many of NASA’s robotic space missions. Her research focuses on the geophysical and geochemical processes that influence the habitability of icy ocean worlds, particularly Jupiter’s moon Europa.
Career and Research
- Affiliation: Research Scientist, Jet Propulsion Laboratory, Pasadena, California.
- Mission Involvement: Trainer has contributed to the scientific planning and instrumentation development for NASA’s Europa Clipper mission, which aims to investigate Europa’s subsurface ocean, ice shell, and potential for supporting life. She has also participated in studies related to the proposed Europa Lander.
- Scientific Focus: Her work integrates planetary geology, geochemistry, and astrobiology to model the exchange of materials between a moon’s interior ocean and its surface ice, assessing the implications for chemical energy sources that could sustain microbial life.
- Publications and Presentations: Trainer has authored and co‑authored peer‑reviewed articles on topics such as cryovolcanism, plume activity, and the habitability of icy satellites. She frequently presents her findings at international conferences, including the Lunar and Planetary Science Conference and the American Geophysical Union meetings.
