Recent Developments of the Space Exploration Synthetic Aperture Radar (SESAR) for Planetary Science Missions

The Space Exploration Synthetic Aperture Radar (SESAR) is a P-band radar instrument for planetary applications being developed at the NASA Goddard Space Flight Center (GSFC). This radar will enable unprecedented surface and near-subsurface measurements of planetary bodies including the Moon, Mars, and asteroids. The radar will measure full polarimetry at meter-scale resolution while featuring a low power, lightweight, beamforming design, specifically developed to meet stringent requirements of planetary instruments. The ongoing prototype development is maturing the SESAR technology for upcoming planetary mission opportunities.
