WASHINGTON: Living on Mars might prove safe enough for future colonists, but a new study shows that radiation exposure on the journey to the Red Planet may be high enough to cause brain damage, jeopardizing any mission that sets out.
Here on Earth, we’re reasonably safe from exposure to cosmic rays. In orbit, astronauts can live worry free for some time on the International Space Station before they exceed exposure limits.
