Space elevator games kick off on Friday.
An airfield in New Mexico will this weekend host a celebration of space technology: the second annual X Prize Cup games.
The festival is a huge space PR exercise and a showcase for private companies working on space technology. But the main draws are three events that will see space enthusiasts competing for a share of $2.5 million in prize money: the Lunar Lander Challenge, the Vertical Rocket Challenge and the Space Elevator Games.
