Also announced at the XPrize Cup Expo and run by the XPrize Foundation, this prize is for a VTVL (vertical take-off, vertical landing) suborbital rocket that can achieve the altitudes and launch energies that are equivalent to what would be needed for a lunar lander. The Vertical Lander Challenge requires 50 meter minimum altitude, horizontal distance of 100 meters, flight time of 90 seconds, and landing on a smooth surface and after refueling, return to its original location. The more aggressive Lunar Lander Challenge increases that to 180s of flight time and landing on a rocky surface. The VLC has a first prize of $350,000, while the LLC has a first prize in excess of this. For 2006 at the Wirefly X PRIZE Cup, Armadillo Aerospace was the only team able to compete. Their vehicle "Pixel" completed one leg of the trip on its third try but crashed shortly after takeoff on the return, leaving all prizes unclaimed.
