"NASA estimates that a return human mission to Mars would take three years. During that time astronauts might receive more than seven times the radiation dose they get during six months on the ISS."
Maybe I'm misunderstanding (I.e. the dose per unit time is 7 times greater), but the way this is phrased, it sounds like the total dose, which isn't too surprising, because 3 years is pretty close to 7 times 6 months.
- iwwr 14y agoThere must be a mistake there somewhere. In a Mars-direct style of mission (the current nasa reference mission), a crew would spend 6 months in space each way and 18 months on the surface. http://www.marssociety.org/home/about/faq http://www.marssociety.org/home/about/faq The danger of radiation is seriously overstated. Technically there is not much missing except a political will to go ahead with it.
