RAD Measures Radiation

January 30, 2012

The Radiation Assessment Detector, the first instrument on NASA’s next rover mission to Mars to begin science operations, was powered up and began collecting data Dec. 6. RAD is the only instrument scheduled to collect science data on the journey to Mars. The instrument is measuring the energetic particles inside the spacecraft to characterize the radiation environment an astronaut would experience on a future human mission to the Red Planet.  credit:  Southwest Research Institute
