These measurements will give a two- Jezero crater on February 18, 2021 [2]. RIMFAX will dimensional radar profile image of the shallow add a new dimension to rover investigations of Mars by subsurface along the rover traverse. Stationary radar providing the capability to image the shallow subsurface soundings can also be collected at different time beneath the rover [3]. The principal goals of the intervals to study diurnal changes in subsurface RIMFAX investigation are to image subsurface dielectric properties due to thermal variations and structure, and to provide information regarding potential interactions between the atmosphere and the subsurface composition.
