Another good game

Yea! More cool "brain races" this time to the moon!
Here's a history of some of the coolest:

• DoT supported SunRayce (build a solar powered car and race it across the US) and World Solar Challenge, (do the same but race it across the Australian continent).
  
• Then there was the DARPA Grand Challenge: to build a car to race on its own
  
• The Ansari X Prize: Launch a reusable manned spacecraft
• And now the X Prize Foundation is starting the $30 million Google Lunar X Prize.
