On this day, 50 years ago, Apollo 11, the first U.S. lunar landing mission, was launched into space
On this day, at 9:32 a.m. EDT, (3.32 p.m. GMT) Apollo 11, the first U.S. lunar landing mission, is launched from Cape Canaveral, Florida, on a historic journey to the surface of the moon. After traveling 240,000 miles in 76 hours, Apollo 11 entered into a lunar orbit on July 19.
The next day, at 1:46 p.m., the lunar module Eagle, manned by astronauts Neil Armstrong and Edwin “Buzz” Aldrin, separated from the command module, where a third astronaut, Michael Collins, remained. Two hours later, the Eaglebegan its descent to the lunar surface, and at 4:18 p.m. the craft touched down on the southwestern edge of the Sea of Tranquility. Armstrong immediately radioed to Mission Control in Houston a famous message, “The Eagle has landed.” At 10:39 p.m., five hours ahead of the original schedule, Armstrong opened the hatch of the lunar module. Seventeen minutes later, at 10:56 p.m., Armstrong spoke the following words to millions listening at home: “That’s one small step for man, one giant leap for mankind.” A moment later, he stepped off the lunar module’s ladder, becoming the first human to walk on the surface of the moon.
Aldrin joined him on the moon’s surface at 11:11 p.m., and together they took photographs of the terrain, planted a U.S. flag, ran a few simple scientific tests, and spoke with President Richard M. Nixon via Houston. By 1:11 a.m. on July 21, both astronauts were back in the lunar module, and the hatch was closed. The two men slept that night on the surface of the moon, and at 1:54 p.m. the Eagle began its ascent back to the command module. Among the items left on the surface of the moon was a plaque that read: “Here men from the planet Earth first set foot on the moon–July 1969 A.D.–We came in peace for all mankind.” At 5:35 p.m., Armstrong and Aldrin successfully docked and rejoined Collins, and at 12:56 a.m. on July 22 Apollo 11 began its journey home, safely splashing down in the Pacific Ocean at 12:51 p.m. on July 24.
