Duke mispronounced his reply as he expressed the relief at Mission Control: "Roger, Twan— Tranquility, we copy you on the ground. You got a bunch of guys about to turn blue. Thanks a lot." 4 32 Two and a half hours after landing, before preparations began for the eva, aldrin radioed to earth: This is the lm pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way. 33 he then took communion privately. At this time nasa was still fighting a lawsuit brought by atheist Madalyn Murray o'hair (who had objected to the Apollo 8 crew reading from the book of Genesis ) demanding that their astronauts refrain from broadcasting religious activities while in space. As such, Aldrin chose to refrain from directly mentioning taking communion on the moon.

4 Apollo 11 landed with less fuel than other missions, and the astronauts encountered a premature low fuel warning. This was later found to be the result of greater propellant 'slosh' than expected, uncovering a fuel sensor. On subsequent missions, extra anti-slosh baffles were added to the tanks to prevent this. 4 Throughout the descent, Aldrin had called out navigation data to Armstrong, who was busy piloting the. A few moments before the landing, a light informed Aldrin that at least one of the 67-inch (170 cm) probes hanging from Eagle 's footpads had touched the surface, and he said: "Contact light!" Three seconds later, eagle landed and Armstrong mission said "Shutdown." Aldrin immediately said. Aca out of detent." Armstrong acknowledged "Out of detent. Auto" and Aldrin continued "Mode control both auto. Descent engine command override off. 413." Charles duke, capcom during the landing phase, acknowledged their landing by saying "We copy you down, eagle." Armstrong acknowledged Aldrin's completion of the post landing checklist with "Engine arm is off before responding to duke with the words, "Houston, Tranquility base here. The eagle has landed." Armstrong's unrehearsed 31 change of call sign from "Eagle" to "Tranquility base" emphasized to listeners that landing was complete and successful.
E., the ones needed for landing. Actually, the computer was programmed to do more than recognize error conditions. A complete set of recovery programs was incorporated into the software. The software's action, in this case, was to eliminate lower priority tasks and re-establish the more important ones. If the computer hadn't recognized this problem and taken recovery action, i doubt if Apollo 11 would have been the successful moon landing it was. 25 a — Letter from Margaret. Hamilton, director of Apollo Flight Computer Programming mit draper Laboratory, cambridge, massachusetts 29, titled "Computer Got loaded published in Datamation, march 1, 1971 Landing Landing on the moon, barbing july 20, 1969 Landing site of Apollo 11 at sea of Tranquility The Apollo 11 landing site. When Armstrong again looked outside, he saw that the computer's landing target was in a boulder-strewn area just north and east of a 300-meter (980 ft) diameter crater (later determined to be west crater, named for its location in the western part of the originally planned. Armstrong took semi-automatic control 30 and, with Aldrin calling out altitude and velocity data, landed at 20:17:40 utc on Sunday july 20 with about 25 seconds of fuel left.
Inside mission Control Center in houston, texas, computer engineer Jack garman told guidance officer Steve bales it was safe to continue the descent, and this was relayed to the crew. The program alarms indicated "executive overflows meaning the guidance computer could not complete all of its tasks in real time and had to postpone some of them. 24 due to an error in the checklist manual, the rendezvous radar switch was placed in the wrong position. This caused it to send erroneous signals to the computer. The result was that the computer was being asked to perform all of its normal functions for landing while receiving an extra load of spurious data which used up 15 of its time. The computer (or rather the software in it) was smart enough to recognize that it was being asked to perform more tasks than it should be performing. It then sent out an alarm, which meant to the astronaut, i'm overloaded with more tasks than I should be doing at this time and I'm going to keep only the more important tasks ;.

Nixon viewed the proceedings from the oval Office of marathi the White house. Citation needed 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.m. It entered Earth orbit, at an altitude of 100.4 nautical miles (185.9 km).9 nautical miles (183.2 km 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 transposition, docking, and extraction maneuver was performed: this involved separating the Apollo command/Service module (CSM) from the spent rocket stage, turning around, and docking with the lunar Module still attached to the stage. After the lunar Module was extracted, the combined spacecraft headed for the moon, while the rocket stage flew on a trajectory past the moon and into orbit around the sun.
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 22 that followed, the crew saw passing views of their landing site in the southern sea of Tranquility ( Mare Tranquillitatis ) about 12 miles (19 km) southwest of the crater Sabine d (0.67408N,.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 extravehicular activity (EVA) challenges. 23 Lunar descent The eagle in lunar orbit after separating from Columbia capcom charles duke, with backup pilots James lovell and Fred haise listening in during Apollo 11's descent On July 20, 1969, the lunar Module eagle separated from the command Module columbia. Collins, alone air aboard Columbia, inspected Eagle as it pirouetted before him to ensure the craft was not damaged. As the descent began, Armstrong and Aldrin found that they were passing landmarks on the surface four seconds early and reported that they were "long they would land miles west of their target point. Five minutes into the descent burn, and 6,000 feet (1,800 m) above the surface of the moon, the lm navigation and guidance computer distracted the crew with the first of several unexpected "1202" and "1201" program alarms.
It also referenced Columbia, a personification of the United States. The lunar Module was named Eagle for the national bird of the United States, the bald eagle, which was featured prominently on the mission insignia. Insignia the Apollo 11 mission insignia was designed by collins, who wanted a symbol for "peaceful lunar landing by the United States". At lovell's suggestion, he chose an eagle as the symbol, put an olive branch in its beak, and drew a lunar background with the earth in the distance. The sunlight in the image was coming from the wrong direction; the shadow should have been in the lower part of the earth instead of the left.
Nasa officials felt that the talons of the eagle looked too "warlike" and after some discussion, the olive branch was moved to the claws. Armstrong was concerned that "eleven" would not be understood by non-English speakers, so they went with "Apollo 11 they decided not to put their names on the patch, so it would "be representative of everyone who had worked toward a lunar landing". All colors are natural, with blue and gold borders around the patch. Citation needed When the eisenhower dollar coin was released in 1971, the patch design provided the eagle for its reverse side. 18 The design was also used for the smaller Susan. Anthony dollar unveiled in 1979, ten years after the Apollo 11 mission. 19 Mementos neil Armstrong's personal preference kit carried a piece of wood from the Wright brothers ' 1903 airplane's left propeller and a piece of fabric from its wing, along with a diamond-studded astronaut pin originally given to deke slayton by the widows of the. This pin had been intended to be flown on Apollo 1 and given to Slayton after the mission but following the disastrous launch pad fire and subsequent funerals, the widows gave the pin to Slayton and Armstrong took it on Apollo. Mission highlights launch and flight to lunar orbit In addition to many 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.

In early 1969, he accepted a job with the national Space council effective august 1969 and announced that he would retire as an astronaut on that date. At that point Ken Mattingly was moved from the support crew into parallel training with Anders as backup cmp in case Apollo 11 was delayed past its intended July launch, at which point Anders would be unavailable. Lovell, haise, and Mattingly would ultimately be assigned as the prime crew of Apollo. Support crew Flight directors Call signs Apollo 11 Command/Service module columbia in lunar orbit, photographed long from the lunar Module eagle After the crew of Apollo 10 named their spacecraft Charlie brown and Snoopy, assistant manager for public affairs Julian Scheer wrote to manned Spacecraft Center. Low to suggest the Apollo 11 crew be less flippant in naming their craft. During early mission planning, the names Snowcone and haystack were used and put in the news release. 14 The command Module was named Columbia after the columbiad, the giant cannon shell "spacecraft" fired by a giant cannon (also from Florida) in Jules Verne 's 1865 novel From the earth to the moon.
Based on the normal crew rotation scheme, armstrong was then expected to command Apollo. There would be one change. Mike collins on the Apollo 8 crew began experiencing trouble with his legs. Doctors diagnosed the problem as revolution a bony growth between his fifth and sixth vertebrae, requiring surgery. Lovell took his place on the Apollo 8 crew, and, when he recovered, collins joined Armstrong's crew as cmp. In the meantime, fred haise filled in as backup lmp, and Aldrin as backup cmp for Apollo. Backup crew The backup crew consisted of lovell as Commander, william Anders as cmp, and haise as lmp. Anders had flown with lovell on Apollo.
the event as "one small step for a man, one giant leap for mankind." Apollo 11 effectively ended the Space race and fulfilled a national goal proposed in 1961. Kennedy : "before this decade is out, of landing a man on the moon and returning him safely to the earth." 6 Contents Framework Crew The crew assignment of neil Armstrong as Commander, jim lovell as Command Module pilot (CMP) and buzz aldrin as Lunar. Apollo 11 was the second all-veteran multi-person crew on an American mission, the first being that of Apollo. An all-veteran crew would not be flown again until sts-26 in 1988. Lovell and Aldrin had previously flown together as the crew of Gemini. The crew was initially assigned as the backup for Apollo. Due to design and manufacturing delays in the lunar Module (lm apollo 8 and Apollo 9 swapped prime and backup crews, and Armstrong's crew became the backup for Apollo.
Apollo 11 was launched. Saturn V rocket from, kennedy Space center on, merritt Island, Florida, on July 16 at 9:32. Edt (13:32 utc) and was the fifth manned mission. Nasa 's, apollo program. The Apollo spacecraft had three parts: a command module (CM) with a cabin for the three astronauts, and the only part that returned to earth; a service module (sm which supported the command module with propulsion, electrical power, oxygen, and water; and a lunar module. After being sent to the moon by the saturn V's third stage, the astronauts separated the spacecraft from it and traveled word for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the lunar module, eagle and landed in the, sea of Tranquility. The astronauts used, eagle 's upper stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned Eagle before they performed the maneuvers that blasted them out of lunar orbit on a trajectory back to earth.
