              17 was the sixth and last Apollo mission in which humans walked 
              on the lunar surface. Apollo 
              17 lifted off after a 2 hour, 40 minute delay due to a malfunction 
              of a launch sequencer. Launch was on Saturn V from Pad 39A at Kennedy 
              Space Center and was the first nighttime launch of an Apollo. On 
              11 December 1972 Commander Eugene A. Cernan and LM pilot Harrison 
              H. Schmitt (the first scientist on the Moon) landed in the Taurus-Littrow 
              region of the Moon while CM pilot Ronald E. Evans continued in lunar 
              orbit.  The 
              LM landed on the southeastern rim of Mare Serenitatis in a valley 
              at Taurus-Littrow, at 20.2 N, 30.8 E. Cernan and Schmitt made three 
              moonwalk extra-vehicular activities (EVAs) totaling 22 hours, 4 
              minutes. During this time they covered 30 km using the Lunar Roving 
              Vehicle, collected 110.5 kg of lunar samples, took photos, set up 
              the ALSEP and performed other scientific experiments. Evans performed 
              experiments from orbit in the CSM during this time. The 
              LM took off from the Moon on 14 December and the astronauts returned 
              to Earth on 19 December. Performance 
              of the spacecraft, the third of the Apollo J-series missions, was 
              excellent for all aspects of the mission. The primary mission goals 
              of investigating the lunar surface and environment in the Taurus-Littrow 
              region, emplacing and activating surface experiments, performing 
              experiments in lunar orbit, obtaining and returning lunar surface 
              samples, and enhancing the capability for future astronaut lunar 
              exploration were achieved. |
