![]() ĭuring training, Armstrong and Aldrin had exclusively used the callsign "Eagle" in simulated ground conversations, both before and after landing. Name Armstrong pilots the Apollo Lunar Module Eagle and lands on the Moon, July 20, 1969, creating Tranquility BaseĪrmstrong named the site at 20:17:58 UTC, approximately 18 seconds after his and Aldrin's successful landing, as he announced: The landing was still within the target ellipse. The automated targeting system was taking Eagle toward what Armstrong described as a " football-field sized crater, with a large number of big boulders and rocks for about one or two crater diameters around it", which he avoided by assuming manual control and flying a bit farther downrange. ![]() On the landing, a combination of thrust from residual pressure in the docking tunnel that connected the Lunar Module with the command module Columbia in orbit, and an imperfect understanding of the Moon's uneven gravitational field, resulted in navigation errors which pushed the powered descent initiation point about 3 miles (4.8 km), and thus the computer-targeted landing spot about 4 miles (6.4 km), downrange (west) of the planned target. Since a precision landing was not expected on the first mission, the target area was an ellipse measuring 11.5 miles (18.5 km) east and west by 3.0 miles (4.8 km) north and south. They were numbered 1 to 5, going from east to west. They ranged between 45 degrees east and west, and 5 degrees north and south of the center of the Moon's facing side. Based on high-resolution photographs taken by the Lunar Orbiter spacecraft, and photos and data taken by the uncrewed Surveyor landers, this list was narrowed down to five sites located near the lunar equator. ![]() National Park Service, and UNESCO have declined to do so, due to the technicality that it is not located within their borders.įor more than two years, NASA planners considered a collection of 30 potential sites for the first crewed landing. states of California and New Mexico have registered Tranquility Base as a heritage site associated with them, but Texas, the U.S. It is located in the south-western corner of the dark lunar plain Mare Tranquillitatis ("Sea of Tranquility"). Tranquility Base was named by Aldrin and Armstrong, and first announced by Armstrong when the Lunar Module Eagle landed. They lifted off the surface on July 21 at 17:54 UTC. The astronauts spent two hours and 31 minutes examining and photographing the lunar surface, setting up several scientific experiment packages, and collecting 47.5 pounds (21.5 kg) of dirt and rock samples for return to Earth. Armstrong exited the spacecraft six hours and 39 minutes after touchdown, followed 19 minutes later by Aldrin. On July 20, 1969, Apollo 11 crewmembers Neil Armstrong and Buzz Aldrin landed their Apollo Lunar Module Eagle at approximately 20:17:40 UTC. Thanks to this support, less than a decade after what became known as Kennedy’s “moon speech,” the National Aeronautics and Space Administration (NASA) sent the first men to the moon.Tranquility Base ( Latin: Statio Tranquillitatis) is the site on the Moon where, in July 1969, humans landed and walked on a celestial body other than Earth for the first time. But we do not intend to stay behind, and in this decade, we shall make up and move ahead.” To meet this goal, Kennedy and his successors, Lyndon Johnson and Richard Nixon, authorized generous funding for space exploration. ![]() Kennedy vowed that America would be first to put a man on the moon, saying “To be sure, we are behind, and will be behind for some time in manned flight. into manned space flight with Yuri Gagarin’s orbital flight in 1961. Later that evening, Nixon recorded succinctly in his diary “the President held an interplanetary conversation with Apollo 11 astronauts Neil Armstrong and Edwin Aldrin on the Moon.”Īmerica and the Soviet Union had been in a race to see who could get to the moon first ever since the Soviets beat the U.S. On July 20, 1969, President Richard Nixon, along with millions of others, watches as two American astronauts walk on the moon. ![]()
