Apollo 11- First Manned Mission
Apollo 11 was the first manned mission to land on the Moon. The first steps by humans on another planetary body were taken by Neil Armstrong and Buzz Aldrin on July 20, 1969. The astronauts also returned to Earth the first samples from another planetary body. Apollo 11 achieved its primary mission – to perform a manned lunar landing and return the mission safely to Earth – and paved the way for the Apollo lunar landing missions to follow.
Summary of Events
The Apollo 11 spacecraft was launched from Cape Kennedy at 13:32:00 UT on July 16, 1969. After 2 hr and 33 min in Earth orbit, the S-IVB engine was reignited for acceleration of the spacecraft to the velocity required for Earth gravity escape.
Lunar-orbit insertion began at 75:50 ground elapsed time (GET). The spacecraft was placed in an elliptical orbit (61 by 169 nautical miles), inclined 1.25 degrees to the lunar equatorial plane. At 80:12 GET, the service module propulsion system was reignited, and the orbit was made nearly circular (66 by 54 nautical miles) above the surface of the Moon. Each orbit took two hours. Photographs taken from lunar orbit provided broad views for the study of regional lunar geology.
The lunar module
The lunar module (LM), with Astronauts Armstrong and Aldrin aboard, was undocked from the command-service module (CSM) at 100:14 GET, following a thorough check of all the LM systems. At 101:36 GET, the LM descent engine was fired for approximately 29 seconds, and the descent to the lunar surface began. At 102:33 GET, the LM descent engine was started for the last time and burned until touchdown on the lunar surface. Eagle landed on the Moon 102 hr, 45 min and 40 sec after launch.
Immediately after landing on the Moon, Armstrong and Aldrin prepared the LM for liftoff as a contingency measure. Following the meal, a scheduled sleep period was postponed at the astronauts’ request, and the astronauts began preparations for descent to the lunar surface.
Astronaut Neil Armstrong
Astronaut Armstrong emerged from the spacecraft first. While descending, he released the Modularized Equipment Stowage Assembly (MESA) on which the surface television camera was stowed, and the camera recorded humankind’s first step on the Moon at 109:24:19 GET (pictured at left). 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.
Deployment of a Solar Wind Composition (SWC) experiment
The astronauts carried out the planned sequence of activities that included deployment of a Solar Wind Composition (SWC) experiment, collection of a larger sample of lunar material, panoramic photographs of the region near the landing site and the lunar horizon, closeup photographs of in place lunar surface material, deployment of a Laser-Ranging Retroreflector (LRRR) and a Passive Seismic Experiment Package (PSEP), and collection of two core-tube samples of the lunar surface.
Approximately two and a quarter hours after descending to the surface, the astronauts began preparations to reenter the LM, after which the astronauts slept. The ascent from the lunar surface began at 124:22 GET, 21 hours and 36 minutes after the lunar landing. In transearth coast only one of four planned midcourse corrections was required. The CM entered the atmosphere of the Earth with a velocity of 36,194 feet per second (11,032 meters per second) and landed in the Pacific Ocean.

NASA Releases Logo to Mark Apollo’s 50th Anniversary
From October 2018 through December 2022, NASA will mark the 50th anniversary of the Apollo Program that landed a dozen Americans on the moon between July 1969 and December 1972. NASA unveiled an official logo for use in observing these milestone anniversaries Friday at the Kennedy Center for the Performing Arts in Washington.
The unveiling was part of “NSO Pops: Space, the Next Frontier,” a National Symphony Orchestra celebration of NASA’s 60 years of accomplishment.
The Apollo 50th anniversary logo is available for download from the NASA Images and Video Library.
Created by NASA graphic artist Matthew Skeins, the logo offers a nod to the past with a few elements borrowed from the original program emblem, and a glimpse into the future with a graphic depiction of NASA’s vision for the next half-century of deep space exploration.
The arc through the word “Apollo” represents Earth’s limb, or horizon, as seen from a spacecraft. It serves as a reminder of how the first views of Earth from the Moon – one of NASA’s crowning achievements — forever transformed the way we see ourselves as human beings. It also affirms NASA’s intention to continue pushing the boundaries of knowledge and delivering on the promise of American ingenuity and leadership in space.
The original Apollo emblem, adopted by the program in 1965, used drawings of the Moon and Earth linked by a double trajectory to portray President John F. Kennedy’s goal of “putting a man on the moon and returning him safely to the earth” by the end of the 1960s. In a similar fashion, the Apollo 50th anniversary logo describes a contemporary goal, with images of the Moon and Mars filling the first and second “O”s, respectively, and the phrase “Next Giant Leap” beneath the word “Apollo.” Neil Armstrong declared his first step onto the lunar surface from the ladder of the Eagle lander on July 20, 1969, to be “one small step for a man, one giant leap for mankind.” Today, NASA is working to return astronauts to the Moon to test technologies and techniques for the next giant leaps – challenging missions to Mars and other destinations in deep space.
The original emblem was a composite design derived from the ideas of NASA employees and contractor personnel. It featured the constellation Orion overlaid on a capital letter “A.” The constellation was positioned so that its three central stars formed the bar in the initial for “Apollo.” In the 50th anniversary logo, elements of the same star field recall the collective effort of some 400,000 people who worked on the Apollo Program – an 11-year series of 33 spaceflights including six that reached the lunar surface. The three central stars are repositioned diagonally beside “50” to emphasize the many sacrifices made in pursuit of the lunar goal — especially the lives of Apollo 1 astronauts Virgil “Gus” Grissom, Ed White and Roger Chaffee who perished in a capsule fire during a test on the launch pad in January 1967.
The star field, like the rest of the anniversary logo, is set against a blue nebula as an acknowledgement that human footprints on distant worlds is not too big a dream, and confirmation that NASA already is working toward that goal.
