ITS official - there are little green men in space. Disappointingly the aliens are not from another planet but were launched from Earth by Google to test the outer limits of their new Nexus S phone. The tiny Android astronauts were strapped to seven payloads, which each contained one of the new mobiles. They were carried into Earths outer atmosphere using weather balloons. (Captain) Zi Wang from Google Android said: 'We wanted an opportunity to collect some interesting data about the sensors in Nexus S - GPS, gyroscope, accelerometer, and magnetometer. The phones were running a variety of apps. Google Maps for Mobile 5.0 (with offline map data) which allowed the team what was directly below the balloon, Google Sky Map to try and identify the real stars in the backdrop and Latitude to report location when the phones had a data connection. Amazingly the Nexus S could withstand temperatures as low as minus 50 degrees celsius, while the GPS kept track of the phone up to 60,000ft and started working again on the balloons descent. The balloons reached heights of over 100,000ft and travelled at up to 139mph at the top of their flight. They were equipped with still and video cameras and footage published on Wednesday shows the moment when the helium-filled balloons popped and the plucky Android astronauts plummeted back to Earth.
