Science – Gene therapy for Mars explorers
Scientists are developing ways to help astronauts survive high levels of radiation in space, and even get them to Mars without the deadly exposure expected during three years of space travel. Talking to the Guardian newspaper, astronaut Commander Scott Kelly called radiation a ‘known hazard’. And, while scientists are planning manned trips to the ‘red planet’ (Mars), they are also preparing a form of genetic fortification of human cells to help protect astronauts against the long-term effects of radiation. It is estimated that a return trip from Mars would expose astronauts to radiation doses of 600 mSv — a large proportion of the lifetime cap...
