Apollo 11 Lunar Module ascent stage photographed from Command Module

Apollo 11 was the first spaceflight that landed humans on the Moon. Americans Neil Armstrong and Buzz Aldrin landed on July 20, 1969, at 20:18 UTC. Armstrong became the first to step onto the lunar surface six hours later on July 21 at 02:56 UTC; Aldrin joined him about 20 minutes later. They spent about two and a quarter hours together outside the spacecraft and collected 47.5 pounds (21.5 kg) of lunar material for return to Earth. The third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit ​until Armstrong and Aldrin returned to it just under a day later for the trip back to Earth. https://en.wikipedia.org/wiki/Apollo_11

The mission plan of Apollo 11 was to land two men on the lunar surface and return them safely to Earth. The spacecraft carried a crew of three: Mission Commander Neil Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin E. Aldrin Jr., was launched by a Saturn V from Cape Kennedy on July 16, 1969, and after three days until they entered lunar orbit. Collins was awaiting on Lunar orbit while the Eagle Lunar Module with Armstrong and Aldrin and has landed in Moon's Mare Tranquillitatis at 3:17 p.m. EST on July 20, 1969. Immediately after landing on the Moon, Armstrong and Aldrin prepared the LM for liftoff as a contingency measure. Following the meal, the astronauts began preparations for the descent to the lunar surface. Armstrong emerged from the spacecraft first. While descending, he released the Modularized Equipment Stowage Assembly on which the surface television camera was stowed, and the camera recorded humankind's first step on the Moon. A sample of lunar surface material was collected and stowed to assure that, if a contingency required an early end to the planned surface activities, samples of lunar surface material would be returned to Earth. Astronaut Aldrin subsequently descended to the lunar surface. The astronauts collected lunar samples, deployed several experiments, and made photographs of the lunar surface. Two and a quarter hours later, the astronauts reentered the Lunar Module, after which the astronauts slept. The ascent from the lunar surface began 21 hours and 36 minutes after the lunar landing. In about four days, the Command Module entered Earth atmosphere and landed in the Pacific Ocean.
