NASA manned Moon-landing project of the 1960s and '70s.
The Apollo spacecraft, supplied with their own low-powered rockets, could brake on approach to the Moon and go into lunar orbit. They also could release part of the spacecraft, the lunar module, with its own rocket power, to land astronauts on the Moon and bring them back to the lunar orbiter. In July 1969 Apollo 11 made the first lunar landing (see Edwin Aldrin ; Neil Armstrong ). In 1970 Apollo 13 was damaged by an explosion in an oxygen tank but returned safely to Earth. Later Apollo missions explored the lunar surface extensively, collecting samples of Moon rocks and installing instruments for research. Apollo 17, the program's final lunar flight, took place in 1972. In total, 12 American astronauts walked on the Moon during six successful lunar-landing missions.
