MISSION

Radiation Assessment Detector

The Radiation Assessment Detector will be one of the first instruments sent to Mars specifically to prepare for future human exploration. The instrument will be the first detector on the surface of Mars to characterize the full radiation environment including galactic cosmic rays, solar energetic particles, secondary neutrons, and other particles created both in the atmosphere and in the martian soil. Before humans ever set foot on the red planet, we must understand the effects of radiation at the surface.
