candidates: Mission highlights. Launch and flight to lunar orbit. In addition to throngs of people crowding highways and beaches near the launch site, millions watched the event on television, with NASA Chief of Public Information Jack King providing commentary. President Richard M. Nixon viewed the proceedings from the Oval Office of the White House. A Saturn V launched Apollo 11 from Launch Pad 39A, part of the Launch Complex 39 site at the Kennedy Space Center on July 16, 1969 at 13:32:00 UTC (9:32:00 a.m. EDT local time). It entered orbit twelve minutes later. After one and a half orbits, the S-IVB third-stage engine pushed the spacecraft onto its trajectory toward the Moon with the Trans-Lunar Injection (TLI) burn at 16:22:13 UTC. About 30 minutes later the command/service module pair separated from this last remaining Saturn V stage and docked with the Lunar Module still nestled in the Lunar Module Adaptor. After the Lunar Module was extracted, the combined spacecraft headed for the Moon, while the third stage booster flew on a trajectory past the Moon and into heliocentric orbit. On July 19 at 17:21:50 UTC, Apollo 11 passed behind the Moon and fired its service propulsion engine to enter lunar orbit. In the thirty orbits that followed, the crew saw passing views of their landing site in the southern Sea of Tranquility (Mare Tranquillitatis) about southwest of the crater Sabine D (0.67408N, 23.47297E). The landing site was selected in part because it had been characterized as relatively flat and smooth by the automated "Ranger 8" and "Surveyor 5" landers along with the "Lunar Orbiter" mapping spacecraft and unlikely to present major landing or extra-vehicular activity (EVA) challenges.
