S71-52263 (1971) --- Astronaut Alan B. Shepard Jr.

Astronaut Alan Shepard (right) was one of 14 astronauts, 8 NASA test pilots, and 2 McDonnell test pilots who took part in simulator studies. Shepard flew the simulator on November 14, 1963. A.W. Vogeley wrote: "Many of the astronauts have flown this simulator in support of the Gemini studies and they, without exception, appreciated the realism of the visual scene. The simulator has also been used in the development of pilot techniques to handle certain jet malfunctions in order that aborts could be avoided. In these situations large attitude changes are sometimes necessary and the false motion cues that were generated due to earth gravity were somewhat objectionable; however, the pilots were readily able to overlook these false motion cues in favor of the visual realism." Roy F. Brissenden noted that: "The basic Gemini control studies developed the necessary techniques and demonstrated the ability of human pilots to perform final space docking with the specified Gemini-Agena systems using only visual references. ... Results... showed that trained astronauts can effect the docking with direct acceleration control and even with jet malfunctions as long as good visual conditions exist.... Probably more important than data results was the early confidence that the astronauts themselves gained in their ability to perform the maneuver in the ultimate flight mission." Shepard commented: "I had the feeling tonight - a couple of times - that I was actually doing the space mission instead of the simulation. As I said before, I think it is a very good simulation." Shepard also commented on piloting techniques. Most astronauts arrived at this same preferred technique: Shepard: "I believe I have developed the preferred technique for these conditions and the technique appeared to me to be best was to come in slightly above the target so that I was able to use the longitudinal marks on the body of the target as a reference, particularly for a lateral translation and, of course, I used the foreshortening effect for a vertical translation, and this appeared to give me the best results. By that I mean the least number of control motions and the lowest fuel usage and the best end techniques, or the best end conditions, I should say." Engineer: "When you started to run you didn't start thrusting immediately I don't believe. It looked like you started working on your attitudes, then started closing in." Shepard: "That is correct. I did that because I felt that I wanted to get the X-axis translation in the most effective vector and for minimum fuel usage that wouldn't introduce any other lateral or vertical offsets that did not already exist." -- Published in Barton C. Hacker and James M. Grimwood, On the Shoulders of Titans: A History of Project Gemini, NASA SP-4203; A.W.

CAPE CANAVERAL, Fla. -- Invited guests enjoy a tribute to astronaut Alan Shepard during a celebration at Complex 5/6 on Cape Canaveral Air Force Station in Florida. The celebration was held at the launch site of the first U.S. manned spaceflight May 5, 1961, to mark the 50th anniversary of the flight. Fifty years ago, astronaut Alan Shepard lifted off inside the Mercury capsule, "Freedom 7," atop an 82-foot-tall Mercury-Redstone rocket at 9:34 a.m. EST, sending him on a remarkably successful, 15-minute suborbital flight. The event was attended by more than 200 workers from the original Mercury program and included a re-creation of Shepard's flight and recovery, as well as a tribute to his contributions as a moonwalker on the Apollo 14 lunar mission.

One stamp commemorates NASA’s Project Mercury, America’s first manned spaceflight program, and NASA astronaut Alan Shepard’s historic flight on May 5, 1961, aboard spacecraft Freedom 7. The other stamp draws attention to NASA’s unmanned MESSENGER mission, a scientific investigation of the planet Mercury. On March 17, 2011, MESSENGER became the first spacecraft to enter into orbit around Mercury. Photo Credit: (NASA/Bill Ingalls)

AS14-64-9135 (6 Feb. 1971) --- Astronaut Alan B. Shepard Jr., commander, took this close-up view of a large boulder, approximately five feet long, during the second extravehicular activity (EVA), on Feb. 6, 1971. Astronauts Shepard and Edgar D. Mitchell, lunar module pilot, descended in the Lunar Module (LM) to explore the moon, while astronaut Stuart A. Roosa, command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit.

AS14-66-9241 (5-6 Feb. 1971) --- Astronaut Edgar D. Mitchell, lunar module pilot, makes a pan with the lunar surface television camera during an extravehicular activity (EVA) on the moon. This photograph was taken by fellow astronaut Alan B. Shepard Jr., commander. While Shepard and Mitchell descended in the Lunar Module (LM) to explore the moon, astronaut Stuart A. Roosa, command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit.

Gordon Cooper, Jr., M. Scott Carpenter, Virgil I. Grissom, John H. Glenn, Jr. and Alan B. Shepard, Jr. Earlier President John F. Kennedy had presented astronaut Shepard with the NASA Distinguished Service Medal (note it on his lapel) in the White House Rose Garden.

AS14-64-9103 (6 Feb. 1971) --- Astronaut Alan B. Shepard Jr., commander, photographed this overall view of a field of boulders on the flank of Cone Crater during the second extravehicular activity (EVA) on the lunar surface. Astronaut Edgar D. Mitchell, lunar module pilot, joined Shepard in exploring the moon, while astronaut Stuart A. Roosa, command module pilot, remained with the Command and Service Modules (CSM) in lunar orbit.

Dr. von Braun addresses a crowd celebrating in front of the Madison County Alabama Courthouse following the successful launch of Astronaut Alan Shepard (America's first astronaut in space) into space on a Mercury-Redstone Launch Vehicle, Freedom 7. Shepard's Mercury Spacecraft, was launched from Cape Canaveral. He reached a speed of 5200 mph. His flight lasted 15-1/2 minutes.

Astronaut Alan B. Shepard, Jr. lifts off in the Freedom 7 Mercury spacecraft on May 5, 1961. This third flight of the Mercury-Redstone (MR-3) vehicle, developed by Dr. Wernher von Braun and the rocket team in Huntsille, Alabama, was the first marned space mission for the United States. During the 15-minute suborbital flight, Shepard reached an altitude of 115 miles and traveled 302 miles downrange.

The Gemini-Titan 3 flight is scheduled to launch on March 23, 1965. Young is the pilot of the GT-3 mission. Shepard was the Mercury Redstone 3 pilot.

The Redstone Test Stand, shown here, was used throughout the 1950s to test the Redstone missionile, including the modified Redstone that launched America's first astronaut, Alan Shepard. The U. S. Department of the Interior's Park Services designated the Test Stand as a National Historic Landmark January 22, 1986.

The Redstone Test Stand was used during the 1950s in early development of the Redstone missile propulsion system. This was the test stand where the modified Redstone missile that launched into space the first American, Alan Shepard, was static tested as the last step before the flight occurred.
