Today, the X PRIZE Foundation announced the official roster of 29 registered teams competing for the $30 million Google Lunar X PRIZE, an unprecedented competition to send a robot to the Moon that travels at least 500 meters and transmit video, images, and data back to the Earth. This group of teams signifies this new era of exploration’s diverse and participatory nature as it includes a huge variety of groups ranging from non-profits to university consortia to billion dollar businesses representing 17 nations on four continents. The global competition, the largest in history, was announced in September 2007, with a winner projected by 2015.
