Astronauts Jack Lousma (seated) and Gerald Carr tested the Lunar Roving Vehicle (LRV) training unit on the sands near Pismo Beach. The vehicle was built by the AC Delco electronics division of General Motors Corporation. Under the direction of Marshall Space Flight Center (MSFC), the LRV was designed to allow Apollo astronauts a greater range of mobility during lunar exploration missions. The LRVs were deployed during the last three Apollo missions; Apollo 15, Apollo 16, and Apollo 17.
