In each life a little rain must fall, but in space, one of the biggest risks to astronauts’ health is radiation “rain.” NASA’s Human Research Program (HRP) is simulating space radiation on Earth following upgrades to the NASA Space Radiation Laboratory (NSRL) at the U.S. Department of Energy’s Brookhaven National Laboratory. These upgrades help researchers on Earth learn more about the effects of ionizing space radiation to help keep astronauts safe on a journey to Mars.
