The best solution for dealing with space junk

October 19, 2012 2:26 pm | by Kasey Panetta, Associate Editor | Articles | Comments

There is a lot of junk in space. There’s American junk, Russian junk, Chinese junk, and corporate junk. There are satellite pieces and discarded rocket parts and metal bits. Basically, all the junk is just floating around clonking into other junk and causing general mayhem when they get a bit too close to the stuff that’s not junk.

Could NASA help paraplegics walk?

October 18, 2012 9:37 am | by Kasey Panetta, Associate Editor | Articles | Comments

NASA has been known to make pretty large contributions to society. But they might have outdone themselves on this one. The agency is currently in the research and development phase for a powered armor suit that could one day allow paraplegics to walk. The suit, called X1, is a robotic exoskeleton designed to be worn over the body to assist in leg movements.
