Apollo Lunar Module The first manned lunar landing occurred on July 20, 1969 with the Apollo 11 LM "Eagle". Four days later, the Apollo 11 crew in the Command Module "Columbia" splashed down in the Pacific Ocean, completing President John F. Kennedy's goal "before this decade is out, of landing a man on the Moon and returning him safely to the Earth." This was followed by precision landings on Apollo 12 "(Intrepid)" and Apollo 14 "(Antares)".In April 1970, the Apollo 13 lunar module "Aquarius" played an unexpected role in saving the lives of the three astronauts after an oxygen tank in the service
Apollo 10 had a very small chance of receiving the Apollo 13 command if he did an outstanding job with the assignment, which he did not. Eisele, despite his issues with management, was always intended for future assignment to the Apollo Applications Program (which was eventually cut down to only the Skylab component) and not a lunar mission. This dress rehearsal for a Moon landing brought the Apollo lunar module to from the lunar surface, at the point where powered descent would begin on the actual landing. Practicing this approach orbit would refine knowledge of the lunar gravitational field needed to calibrate
