Mars is a planet ripe for exploration by mankind. Or is it? As NASA struggles to justify a manned mission to the Red Planet, what technology will we need to get there? Also, before we set foot on the Martian surface, what advanced rovers will we need to scope out the surroundings, making sure it's safe? But before we start getting bogged down with all these details, what's there and how can we exploit it?
Mining Mars? Where's the Ore?
We may not be prospecting Mars anytime soon, but scientists have mapped out where on the planet we should look -- some day.
We've explored Mars with satellites, landers and rovers, could the next robotic exploration vehicle be spherical in shape and inspired by the humble wind-blown tumbleweed?
New concepts for Mars-probing rovers would use Martian wind to move around the planet. James Williams gets a look at two of the designs.
