The Kennedy Space Center launch team is continuing the checkout of Apollo 17 flight hardware for the final lunar exploration mission of Project Apollo. A mission simulation to check out the lunar roving vehicle and all its systems was successfully carried out. Participating in the test, conducted in conjunction with the Manned Spacecraft Center in Houston, Texas, were prime crew members Harrison H. Schmitt, Lunar Module Pilot, left, and Eugene A. Cernan, Commander. Rollout of the Apollo 17 space vehicle to Complex 39's Pad A is scheduled for August 28. The lunar module which will carry Cernan and Schmitt down to the lunar surface is visible in the background.
