The lens, meanwhile, is expected to fetch about half that, even though it appears to be held together with duct tape and velcro. If that price seems a little steep given the wear-and-tear, consider this: that duct tape has been signed by Commander Scott himself and the auctioneers believe it "possibly retains some lunar dust."

This video of Commander Scott falling over, camera in hand, might have something to do with that:

If cameras aren't your thing, there are 671 other NASA treasures up for sale, with many of the proceeds going to benefit the Astronaut Scholarship Foundation. While a prototype lunar rover that has been rescued from the scrap heap might sound like the sexiest of the bunch, the best Father's Day gifts are actually this mechanical pencil that went into space and an ejection seat that happens to still be "in very good condition."
