The Mars Odyssey spacecraft produced these new maps of the radiation levels astronauts would encounter on the surface of the Red Planet. The safest areas (blue) are in low-altitude zones where the thin Martian atmosphere provides maximal protection from cosmic rays. There the annual dose would come to about 10 rems, roughly one-third the flux on the international space station.
