Exploration and Characterization of the Regolith of Microgravity Bodies

Organization National Aeronautics and Space Administration (NASA) Reference Code 0299-NPP-NOV26-GSFC-PlanetSci Field of Science Planetary Science Description The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly‑talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA‑affiliated research institute. These one‑to‑three‑year fellowships are competitive and designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology. Responsibilities for this postdoctoral position include developing measurement techniques to characterize the regolith structure, temperature at depth, thermal conductivity, and volatile content of small, microgravity bodies such as comets, asteroids, and small moons. The researcher will design and construct a projectile‑based probe equipped with a three‑axis accelerometer and a thermal probe, optimize penetration into and recording of the regolith structure, conduct trade studies to select stabilization methods, and carry out experimental studies at the Tower Test Facility to validate probe designs and protocols across a range of microgravity bodies. The scientist will also investigate the generalization of probe techniques for deploying additional sensors, anchoring, and other exploratory missions. Qualifications An educational background in geology, materials science, soil mechanics, or planetary sciences is required. Practical knowledge in the design, construction, and execution of experimental studies on regolith materials or their analogs is extremely useful for the design and execution of new experimental studies of regolith probes.
