Once we leave the atmosphere and travel beyond the cocoon of Earth’s magnetic field, the radiation environment changes dramatically. With talk increasingly turned towards a return to the Moon and manned trips to Mars, what radiation problems will our astronauts encounter?
Space is a harsh environment. We’re all familiar with the big risks from television – asteroids, solar flares, lack of air, extreme temperatures, and the occasional testy alien ships. What we don’t think about quite as much is the radiation. With trips to the Moon and Mars, in the planning stages, we are once again about to send people into that harsh universe. In addition to the engineering, logistics, and everything else that goes into such trips, NASA is looking at revising the limits for radiation exposure its astronauts can receive.
