Apollo 17 was the sixth and last Apollo mission in which humans walked on the lunar surface. On 11 December 1972 two astronauts (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 in the Lunar Module (LM) while the Command and Service Module (CSM) (with CM pilot Ronald E. Evans) continued in lunar orbit. During their stay on the Moon, the astronauts set up scientific experiments, took photographs, and collected lunar samples. The LM took off from the Moon on 14 December and the astronauts returned to Earth on 19 December.
