HistoryInspiringApollo 17 astronaut Gene Cernan was driving the Moon rover in December 1972. The nearest repair shop was 238,000 miles away. A hammer in his pocket snapped off the rear fender. Moon dust began coating the crew and the rover's controls. Mission Control spent the night designing a fix. Cernan and Schmitt taped four lunar maps together and clamped on the homemade fender. It held for the rest of the mission. The fender is still on display today.2 hours ago
