Antenna  Technologies for Mars Subsurface Radar — Future  exploration missions to Mars could use Synthetic Aperture Radar ( SAR ), a  microwave remote-sensing technology to  conduct surveys beneath its surface. This contract will develop an Engineering  Development Unit, a P-band feed antenna that could be used in a P-Band SAR to assist  in mapping water and ice in potential future Mars missions, in order to  understand the Mars hydrologic system and how it has changed over time.
