NASA’s Human Research Program (HRP) is studying the effects radiation plays on the human body and developing ways to monitor and protect against this silent hazard. High-energy galactic cosmic rays (GCRs) which are remnants from supernovas and solar storms like solar particle events (SPEs) and coronal mass ejections (CMEs) from the sun can cause harm to the body and spacecraft. These are all components of space weather

“Dosimeters and modeling techniques are used to determine how much energy is deposited in the space explorer’s bodies along with inflight tools to try to estimate what type...
