NASA Looks To Past To Build New Moon Rovers

Some parts are easier to come by than others. Take the three original lunar rovers: They're still on the moon, and so are their tires — which posed a problem for NASA scientists trying to re-create the moon tires for a new lunar mission.

No one at NASA remembered how they were built, and the instructions had been lost. But it turns out that a spare was closer to home, stored for 40 years in the closet of the engineer who designed the original moon buggy. NASA is using it to build new ones.
