Thirty-five years
Oh, and today is the 35th anniversary of the first Apollo moon landing. We sent a handful of people there, then stopped.
Fearless Leader said something about going back and then to Mars once there was a lot of excitement about Spirit and Opportunity. (As a side note, there are probably more electronics in the arms of the rovers than in the entirety of the Apollo modules. Just a guess but I bet it's close.) Of course, like so many of Fearless Leader's proclaimations, there hasn't been much followthrough.
I want my flying car. I want my own personal robot.
How can I retire on the moon if we haven't been there since I was a toddler?
