This is a close-up view of a right rear wheel strut of the Lunar Roving Vehicle (LRV) No. 1. The LRV was built to give Apollo astronauts a greater range of mobility during lunar exploration. It was an open-space and collapsible vehicle about 10 feet long with large mesh wheels, anterna, appendages, tool caddies, and camera. An LRV was used on each of the last three Apollo missions; Apollo 15, Apollo 16, and Apollo 17. It was built by the Boeing Company under the direction of the Marshall Space Flight Center.
