The Apollo 17 spacecraft, containing astronauts Eugene A. Cernan, Ronald E. Evans, and Harrison H. Schmitt, glided to a safe splashdown at 2:25 p.m. EST on Dec. 19, 1972, 648 kilometers (350 nautical miles) southeast of American Samoa. The astronauts were flown by recovery helicopter to the U.S.S. Ticonderoga slightly less than an hour after the completion of NASA’s sixth and last manned lunar landing in the Apollo program. Image Credit: NASA
