Passive Sounding of Solar System Bodies Using Radio Astronomical Sources

0323-NPP-NOV26-JPL-PlanetSci Description
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-skilled scientists who can engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology. Passive radar sounding is an emerging technique that uses naturally occurring radio emissions to investigate planetary surfaces and subsurfaces, offering a low-resource, low-risk alternative to active radar systems. This approach is especially promising in environments with strong natural radio sources, such as the Jovian system, where decametric emissions (DAM) may enable passive probing of icy moons, as well as in resource-limited mission architectures, including aerial platforms like helicopters on Mars. As planetary exploration increasingly targets challenging terrains and subsurface environments, there is a growing need to assess the viability and scientific potential of passive sounding. This research opportunity invites innovative studies to advance the scientific and technical understanding of passive radar sounding using planetary radio emissions. Areas of interest include characterizing the spectral and temporal properties of planetary emissions such as DAM; improving methods for detection, auto‑correlation, and depth retrieval; validating signal‑reflection models through analysis of radar data; and evaluating the performance and limitations of passive sounding in realistic mission scenarios. Proposals may address applications to icy moons, but are not limited to them; passive sounding techniques may also be applicable to other planetary settings, including Mars, where resource‑constrained platforms such as helicopters could benefit from instrumentation that avoids the need for high‑power transmitters.
