Apollo 16 lunar module pilot, Charles Duke (left) and Commander John Young checked out operation of Lunar Roving Vehicle 2 (LRV-2), which will carry them on traverses of the Moon's surface, in the Manned Spacecraft Operations building today. As they simulated an EVA on the Moon they activated all LRV systems to assure operation within design specifications. Apollo 16 Backup Commander Fred Haise and Backup Lunar Module Pilot Edgar Mitchell also simulated a mission on the lunar surface during the day.
