ESA is announcing a new programme for conducting research into radiation and how to protect astronauts from space radiation. Teaming up with five particle accelerators in Europe, we are offering researchers slots to bombard samples with radiation.
Cosmic radiation is considered to be the main health hazard to human spaceflight and exploration of the Moon, Mars and beyond. Finding ways to limit the harmful effects are increasingly important as we embark on longer missions further from Earth.
Our atmosphere protects us on the ground from the constant barrage of cosmic radiation, but venture 50 km up – the International Space Station circles at around 400 km – and the only thing protecting astronauts is the hull or their spacesuits. The longer the exposure, the higher the risk of developing cancer, central nervous system disorders, cardiovascular problems and tissue degeneration.
