The Mission Of Apollo 11

Good Essays

On July 20, 1969, humanity did itself proud in spite of all its wars, sadism, hatred, and insanity. We set foot on another planet. Men walked on the moon. This changed our belief in what we could accomplish.
On July 20, 1969, the lunar module landed. Humanity did itself proud on that day. Until now nothing this big had ever been accomplished. The dream of traveling to the moon was already centuries old when the second World War ended in 1945. The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth. Apollo 11 would be the mission to achieve the goal that President Kennedy had laid down, with more than five months to spare before the end-of-decade deadline. On July 19, after Apollo 11 had flown behind the moon out of contact with Earth, came the first lunar orbit insertion maneuver. At about 75 hours, 50 minutes into the flight, a retrograde firing of the SPS for 357.5 seconds placed the spacecraft into an initial, elliptical-lunar orbit of 69 by 190 miles. Later, a second burn of the SPS for 17 seconds placed the docked vehicles into a lunar orbit of 62 by 70.5 miles, which was calculated to change the orbit of the CSM piloted by Collins. The change happened because of lunar-gravity perturbations to the nominal 69 miles required for subsequent LM rendezvous and docking after completion of the lunar landing. Before this second SPS firing, another TV transmission was
