When do you foresee the first private lunar landing?

Assuming you mean robotic lunar landings, I'd say... early 2013. Note--that's just a guess, and doesn't reflect any confidential information from our teams.

If you mean landing of a human crew... 2025. I think I'll still be of acceptable astronaut age then, so if anyone is looking for a crew member, you know where to find me...

Ask me about the X PRIZE Foundation's space activities, including the Google Lunar X PRIZE.
