LRO Data Shows That Astronauts May Face High Levels Of Radiation In 2020.

New Scientist (10/21, Aron, 183K) reports that a team led by Nathan Schwadron at the University of New Hampshire used data from the Lunar Reconnaissance Orbiter (LRO) to simulate the amount of cosmic radiation astronauts will face during long-duration missions into deep space when the sun is at its weakest in 2020. Those spending a year or more in space would receive more radiation than currently allowed by NASA’s safety limits. Because current technologies may not be able to sufficiently deal with the situation, the article noted that NASA may have to “rethink” its policy in general. NASA’s Rachel Kraft said, “The radiation measurements from the LRO are an important addition to our understanding of the fluctuating space radiation environment and potential radiation risks. ... NASA is developing human health countermeasures to minimise the risks to crew members during space exploration missions beyond low Earth orbit.”
