Spirit's in reverse

Is anyone else as amazed of the Mars rovers as I am? They were originally slated to only last- what, 6 months? I don't know the precise figure because frankly I'm too lazy to look it up. But man, they're going on something like 1800 days in service.

Pay little attention to the fact that Spirit is now traveling in reverse because her front wheel is broken. Its amazing to me.

Way to go Nasa on these (and hopefully more to come) extraordinary achievements.

Check out the TED talk about the rovers here, also gives some candid stories from the NASA team:
