We already know the radiation levels on Mars' surface are safe enough for us to go ahead and start building vacation homes. But, before we can finish our plans for the pool, there are still a few more tests that need to be done. There's just one problem: the planet has a way of destroying all of the scientific equipment we send to check it out. (If we're pointing fingers, mostly because of the magnetized dust on its surface.) Rather than send another rover to be demolished far away from home, Madrid's Center for Astrobiology thinks they've created a way to test out every robotic arm and camera while they're still on Earth using a device called MARTE.
