NASA introduces America’s first astronauts

On April 9 1959 the National Aeronautics and Space Administration (NASA) introduces Americas first astronauts to the press Scott Carpenter L.Gordon Cooper Jr.John H.

Glenn Jr.Virgil Gus Grissom Walter Schirra Jr.Alan Shepard Jr.

and Donald Slayton.The seven men all military test pilots were carefully selected from a group of 32 candidates to take part in Project Mercury Americas first manned space program.NASA planned to begin manned orbital flights in 1961.On October 4 1957 the USSR scored the first victory of the space race when it successfully launched the worlds first artificial satellite Sputnik into Earths orbit.

In response the United States consolidated its various military and civilian space efforts into NASA which dedicated itself to beating the Soviets to manned space flight.In January 1959 NASA began the astronaut selection procedure screening the records of 508 military test pilots and choosing 110 candidates.This number was arbitrarily divided into three groups and the first two groups reported to Washington.

Because of the high rate of volunteering the third group was eliminated.Of the 62 pilots who volunteered six were found to have grown too tall since their last medical examination.An initial battery of written tests interviews and medical history reviews further reduced the number of candidates to 36.

After learning of the extreme physical and mental tests planned for them four of these men dropped out.The final 32 candidates traveled to the Lovelace Clinic in Albuquerque New Mexico where they underwent exhaustive medical and psychological examinations.The men proved so healthy however that only one candidate was eliminated.The remaining 31 candidates then traveled to the Wright Aeromedical Laboratory in Dayton Ohio where they underwent the most grueling part of the selection process.

For six days and three nights the men were subjected to various tortures that tested their tolerance of physical and psychological stress.Among other tests the candidates were forced to spend an hour in a pressure chamber that simulated an altitude of 65000 feet and two hours in a chamber that was heated to 130 degrees Fahrenheit.At the end of one week 18 candidates remained.

From among these men the selection committee was to choose six based on interviews but seven candidates were so strong they ended up settling on that number.After they were announced the Mercury Seven became overnight celebrities.The Mercury Project suffered some early setbacks however and on April 12 1961 Soviet cosmonaut Yuri Gagarin orbited Earth in the worlds first manned space flight.Less than one month later on May 5 astronaut Alan Shepard was successfully launched into space on a suborbital flight.

On February 20 1962 in a major step for the U.S.space program John Glenn became the first American to orbit Earth.NASA continued to trail the Soviets in space achievements until the late 1960s when NASAs Apollo program put the first men on the moon and safely returned them to Earth.

In 1998 36 years after his first space flight John Glenn traveled into space again.Glenn then 77 years old was part of the Space Shuttle Discovery crew whose 9-day research mission launched on October 29 1998.Among the crews investigations was a study of space flight and the aging process.
