Moon mission will test an anti-radiation vest for astronauts
For astronauts headed to Mars, the biggest threat might not be an unforgiving climate or dwindling supplies -- it could be gamma ray radiation that gradually wrecks their bodies. Explorers may soon have a way to shield themselves, though. StemRad has revealed that its AstroRad anti-radiation vest is set to trialed aboard the Orion capsule when it orbits around the Moon during its late 2018 dry run. The non-metallic, layered shields are custom-fitted to each astronaut in order to protect their vital organs without bogging them down.
