The five remaining contenders will now compete for two near-end-goal prizes: the Lunar Arrival and the Soft Landing Milestone Prize. To win Lunar Arrival and its $1.75 million reward, the team's spacecraft has to complete one orbit around the moon or enter a direct descent approach to the moon's surface. In order to win Soft Landing's $3 million reward, though, the team's spacecraft must be able to beam data back to Earth to prove that it has landed on the lunar surface.
The Google Lunar Xprize challenged teams from all over the globe to develop a privately funded spacecraft that can land on Earth's faithful companion. It must also be able to travel 500 meters on the moon and send back high-res images and videos. The five final contenders announced in January have until March 31st, 2018 to reach the project's ultimate goals and win the Grand Prize that's worth a cool $20 mil.
