XPRIZE, the global leader in incentivized prize competition, today announced that five Google Lunar XPRIZE teams have been awarded a combined US$5.25 million in recognition of key technological advancements toward their quest to land a private spacecraft on the surface of the moon. Determined by a judging panel of science, aeronautics and space industry experts that evaluated numerous tests over the past year, the Milestone Prizes honor hardware and software innovations needed to overcome technical risks in the three crucial areas—Imaging, Mobility and Landing systems—all of which are necessary to complete a successful Google Lunar XPRIZE mission.
