Could lava tubes, caves, or subsurface habitats offer safe refuge for future astronauts on Mars? Scientists with NASA’s Curiosity Mars rover team are helping explore questions like that with the Radiation Assessment Detector, or RAD.
Unlike Earth, Mars doesn’t have a magnetic field to shield it from the high-energy particles whizzing around in space. That radiation can wreak havoc on human health, and it can seriously compromise the life support systems that Mars astronauts will depend on, as well.
Based on data from Curiosity’s RAD, researchers are finding that using natural materials such as the rock and sediment on Mars could offer some protection from this ever-present space radiation. In a paper published this summer in JGR Planets, they detailed how Curiosity remained parked against a cliff at a location called “Murray Buttes” from Sept. 9 to 21, 2016.
