There's a  slight  chance that the Earth could get hit by an asteroid in about 170 years, but don't you worry -- NASA's all over it. This week, the agency announced a new mouthful of a mission known as Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer, or OSIRIS-REx, for short. The $800 million initiative, part of NASA's New Frontiers Program, will send a spacecraft to link up with 1999 RQ36 -- a nearby asteroid that's likely rich in carbon and other organic molecules that could explain how life forms originated. After about four years of space travel, the craft should get close enough to map the asteroid's surface, before using its robotic arm to extract at least two ounces of material and return it to Earth by 2023. Scientists will also pay close attention to something known as the Yarkovsky effect, which determines how an asteroid's path changes as it absorbs and emits energy from the sun. OSIRIS-REx will attempt to measu...

A tiny robotic ball able to be controlled by a smartphone doesn't exactly need any more selling points, but Orbotix's Sphero now has an extra one nonetheless. It's been outfitted with a chariot that can be used for FaceTime sessions or low-level surveillance -- or chariot races around your office, naturally. Of course, this is strictly a DIY affair, but we're guessing this is one project you will actually want to do yourself once you see the video after the break.  Orbotix
