The risk of radiation-induced cancer poses a serious obstacle to long duration spaceflight and planetary exploration. In space, astronauts are exposed to types of radiation not experienced on Earth. The exposures are at low dose rate, but on planned protracted missions or multiple short duration missions, the cumulative doses are large enough to pose an unacceptably high risk of radiation-induced fatal cancer. Currently, astronauts on multiple International Space Station (ISS) missions approach acceptable radiation dose limits. Projected missions such as an asteroid redirect mission or a Mars mission will exceed permissible exposure limits. Research is ongoing to accurately quantify cancer risks from space radiation and to reduce them.
