KENNEDY SPACE CENTER, FLA. -- Before the induction ceremony of five space program heroes into the U.S. Astronaut Hall of Fame, astronaut John Young is warmly greeted as he is introduced as a previous inductee. Co-holder of a record for the most space flights, six, he flew on Gemini 3 and 10, orbited the Moon on Apollo 10, walked on the Moon on Apollo 16, and commanded two space shuttle missions, STS-1 and STS-9. Young currently serves as associate director, technical, at Johnson Space Center. The induction ceremony was held at the Apollo/Saturn V Center at KSC. New inductees are Richard O. Covey, commander of the Hubble Space Telescope repair mission; Norman E. Thagard, the first American to occupy Russia’s Mir space station; the late Francis R. "Dick" Scobee, commander of the ill-fated 1986 Challenger mission; Kathryn D. Sullivan, the first American woman to walk in space; and Frederick D. Gregory, the first African-American to command a space mission and the current NASA deputy administrator. 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 five inductees join 52 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.

S65-18762 (March 1965) --- Effects of the weightless environment on cell division, the basic growth process for living tissue, will be studied during the Gemini-Titan 3 flight scheduled for March 23, 1965. A spiny black sea urchin (upper left) is stimulated by mild electric shock or potassium chloride. As a result it sheds many thousands of eggs. When fertilized, these eggs become actively dividing cells very similar in basic processes to cells of other animals, including humans. These pictures show stages of cell division. At upper right is a single cell; at lower right cell divisions have produced many cells. Cell photos are magnified about 700 times, and all cells shown are too small to be seen by the naked eye. (Photos at upper right and lower left are of sea urchin eggs. Group of cells at lower right are from a sand dollar, which like the sea urchin, is an Echinoderm. Its eggs are virtually identical and are used interchangeably with those of the sea urchin in NASA Ames Center weightlessness experiments.) The Gemini experiment will involve cell division like that shown here. This will take place during several hours of weightlessness aboard the Gemini spacecraft. The experiment will be flown back to laboratories at Cape Kennedy after spacecraft recovery. It has been designed so that any abnormal cell division found by postflight analysis should suggest that the weightless environment has effects on individual cells. This might mean hazards for prolonged periods of manned spaceflight.

KENNEDY SPACE CENTER, FLA. -- Former astronaut Owen Garriott acknowledges the applause as he is introduced as a previous inductee into the U.S. Astronaut Hall of Fame. He and other Hall of Fame members were present for the induction of five new space program heroes into the U.S. Astronaut Hall of Fame: Richard O. Covey, commander of the Hubble Space Telescope repair mission; Norman E. Thagard, the first American to occupy Russia’s Mir space station; the late Francis R. "Dick" Scobee, commander of the ill-fated 1986 Challenger mission; Kathryn D. Sullivan, the first American woman to walk in space; and Frederick D. Gregory, the first African-American to command a space mission and the current NASA deputy administrator. Garriott exercised his expertise as a solar physicist on two space missions, the 59-day Skylab 3 flight in 1973, and an 11-day trip aboard the Space Shuttle Columbia a decade later. The induction ceremony was held at the Apollo/Saturn V Center at KSC. 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 five inductees join 52 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.

S65-18766 (March 1965) --- Diagram of experiment planned for the Gemini-Titan 3 mission scheduled on March 23, 1965, to find out if there are effects of weightlessness on individual living cells. The round canister (top) shows the experiment package. It will contain eight identical chambers, each with sections of sperm, eggs and fixative. Cells are eggs of the spiny, black sea animal, the sea urchin. Bottom panel shows the three stages of each chamber. From left in the first stage, sperm, eggs and fixative are separated. By turning the handle, astronauts will fertilize a certain portion of the eggs, which will begin to divide. At 20 minutes after launch, further turns of the handle will force fixative into two chambers and stop cell division. At 70 minutes after launch, cell division in four more chambers will be stopped, and just prior to re-entry, growth of the remaining two chambers will be terminated by a turn of the handle. This system will allow study after the flight of how cells divided after various time periods in weightlessness. Abnormalities would suggest weightlessness effects on living tissue and possible hazard to prolonged manned spaceflight.

KENNEDY SPACE CENTER, FLA. -- Former astronaut Robert Crippen smiles at the warm greeting he is receiving when introduced as a previous inductee into the U.S. Astronaut Hall of Fame. He and other Hall of Fame members were present for the induction of five new space program heroes into the U.S. Astronaut Hall of Fame: Richard O. Covey, commander of the Hubble Space Telescope repair mission; Norman E. Thagard, the first American to occupy Russia’s Mir space station; the late Francis R. "Dick" Scobee, commander of the ill-fated 1986 Challenger mission; Kathryn D. Sullivan, the first American woman to walk in space; and Frederick D. Gregory, the first African-American to command a space mission and the current NASA deputy administrator. Crippen piloted the first Space Shuttle flight in 1981 and commanded three other Shuttle missions in the next 3-1/2 years. In the early 1990s he served as director of NASA’s Kennedy Space Center. The induction ceremony was held at the Apollo/Saturn V Center at KSC. 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 five inductees join 52 previously honored astronauts from the ranks of the Gemini, Apollo, Skylab, Apollo-Soyuz, and Space Shuttle programs.

Famed astronaut Neil A. Armstrong, the first man to set foot on the moon during the historic Apollo 11 space mission in July 1969, served for seven years as a research pilot at the NACA-NASA High-Speed Flight Station, now the Dryden Flight Research Center, at Edwards, California, before he entered the space program. Armstrong joined the National Advisory Committee for Aeronautics (NACA) at the Lewis Flight Propulsion Laboratory (later NASA's Lewis Research Center, Cleveland, Ohio, and today the Glenn Research Center) in 1955. Later that year, he transferred to the High-Speed Flight Station at Edwards as an aeronautical research scientist and then as a pilot, a position he held until becoming an astronaut in 1962. He was one of nine NASA astronauts in the second class to be chosen. As a research pilot Armstrong served as project pilot on the F-100A and F-100C aircraft, F-101, and the F-104A. He also flew the X-1B, X-5, F-105, F-106, B-47, KC-135, and Paresev. He left Dryden with a total of over 2450 flying hours. He was a member of the USAF-NASA Dyna-Soar Pilot Consultant Group before the Dyna-Soar project was cancelled, and studied X-20 Dyna-Soar approaches and abort maneuvers through use of the F-102A and F5D jet aircraft. Armstrong was actively engaged in both piloting and engineering aspects of the X-15 program from its inception. He completed the first flight in the aircraft equipped with a new flow-direction sensor (ball nose) and the initial flight in an X-15 equipped with a self-adaptive flight control system. He worked closely with designers and engineers in development of the adaptive system, and made seven flights in the rocket plane from December 1960 until July 1962. During those fights he reached a peak altitude of 207,500 feet in the X-15-3, and a speed of 3,989 mph (Mach 5.74) in the X-15-1. Armstrong has a total of 8 days and 14 hours in space, including 2 hours and 48 minutes walking on the Moon. In March 1966 he was commander of the Gemini 8 or
