Lunar Roving Vehicle Fender Repair - Apollo 17

Just after unloading the Lunar Roving Vehicle (LRV), Apollo 17 commander Eugene Cernan accidentally knocked off the right-rear fender extension. He taped it back on but it fell of later, and the wheel kicked a plume of fine lunar dust over the rover and its occupants. At the suggestion of technicians on Earth, Cernan and lunar module pilot Harrison Schmitt taped together several plastic-coated map sheets to make a replacement fender extension.

Shown here are a spare wheel and fender and a fender extension brought back from Apollo 17, and the replacement for the extension made of map sheets and tape on the moon.
