Google's Lunar Xprize is still up for grabs, and researchers at Carnegie Mellon University think they have a chance of bagging the $30 million prize (which requires landing a robot on the Moon, moving it 500 meters and sending video back to Earth). The team's solution plans to beam footage back from the moon via a telepresence robot. Instead of simply broadcasting shots of the moon's surface, however, the scientists told the BBC they want to go a stage further and "bring the Moon back". How? By pairing the spacefaring robot with Oculus Rift headsets here on Earth; turn your head and the robot on the moon will supposedly turn in tandem via head-tracking. There were a few issues that had to be overcome, however. Namely, the Rift needs a pair of simultaneous video feeds to achieve a convincing virtual reality experience, and, by design it can't accept two streams.
