Tiger4 writes "The X-Prize foundation and NASA have signed off on a $2.5 million prize for proof of concept lunar lander vehicles. From the article, 'NASA Deputy Administrator Shana Dale told MSNBC.com that the point of the competition was to "take advantage of new innovative technologies that have been developed" since the last lunar landing, during the Apollo 17 mission in 1972." There are two levels of competition, "In the Level 1 competition, the vehicles must be in the air for at least 90 seconds during each leg of the round trip, and land on a flat, even surface. The Level 2 competition is harder -- requiring 180 seconds of flight each way, with a rocky, lunar-style landing site.' NASA and X-Prize people are still working on the final rules, but they are already signing up teams and expect to see vehicles in time for the X-Prize exhibition in New Mexico, October 18-21, 2006."
