KENNEDY SPACE CENTER, FLA. - At the KSC Visitor Complex, former astronaut Robert L. Crippen (right) presents former astronaut Sally K. Ride (standing center) at her induction ceremony into the U.S. Astronaut Hall of Fame. Also standing is former astronaut James A. Lovell. Seated on the dais are, from left, former astronauts John H. Glenn, Gordon Cooper, Buzz Aldrin, and Walter Cunningham, all previously inducted into the Hall of Fame. Being inducted with Ride are Space Shuttle astronauts Daniel Brandenstein, Robert "Hoot" Gibson, and Story Musgrave. Conceived by six of the Mercury Program astronauts, the U.S. Astronaut Hall of Fame opened in 1990 to provide a place where space travelers could be remembered for their participation and accomplishments in the U.S. space program. The four new inductees join 48 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.

The Space Race began with a shock to the American public when the Soviet satellite Sputnik was launched in 1957. United states created NASA accelerate U.S. space exploration efforts and launched the Explorer 1 satellite in 1958. The Soviet Union was first again when it puts the first human, cosmonaut Yuri Gagarin, into a single orbit on April 12, 1961. Shortly after this, on May 5, the U.S. launched Alan Shepard, on a suborbital flight and reached its orbital goal on February 20, 1962, when John Glenn made three orbits around the Earth in the Mercury capsule. The Mercury space capsule was a pressurized cabin produced by McDonnell Aircraft and carried supplies of water, food, and oxygen for about one day. Mercury was launched on a top of modified Atlas D ballistic missiles. The capsule was fitted with a launch escape rocket to carry it safely away from the launch vehicle in case of a failure. Small retrorockets were used to bring the spacecraft out of its orbit, after which an ablative heat shield protected it from the heat of atmospheric reentry. Finally, a parachute slowed the craft for a water landing. Both astronaut and capsule were recovered by helicopters deployed from a U.S. Navy ship. The Mercury project missions were followed by millions on radio and TV around the world. Its success laid the groundwork for Project Gemini, which carried two astronauts in each capsule and perfected space docking maneuvers essential for manned lunar landings in the Apollo program announced just a few weeks after the first manned Mercury launch.

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.

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.
