Mercury, The Original Seven

Mercury, The Original Seven

Ok, I have written already about Apollo, so let's be totally confusing and I will go back to the program of Original Seven. The Mercury Program, the piloted spaceflight between May 1961 and May 1963.These seven original American astronauts were Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard, Deke Slayton. The main goal was to put a man into the Earth's orbit and return him safely to the Earth. Mercury capsule was a pressurized cabin supplied by food, oxygen and water for a day.  

The member of Original Seven group took part of all following programs: Mercury, Gemini, Apollo (Gus Grissom died during the fire in Apollo 1), Space shuttle. John Glenn became the oldest person to fly in space in Shuttle flight.



The first man in space on the orbital flight was the Soviet cosmonaut Jurij Gagarin (on April 21, 1961). Alan Shepard became the first American astronaut on suborbital flight 3 weeks after him, on May 5, 1961. John Glenn, the third Mercury astronaut, became the first American to reach the orbit on February 20, 1962, but it happened only after the day-long space flight of Soviet cosmonaut Gherman Titov nn August 1961.

The project was generally successful, however some problems appeared, such as medical problems of personal hygiene and post-flight low blood pressure. Every flight had its number and call sign followed by number 7, which was the symbolic of the first 7 astronauts.

The first suborbital ballistic flights were developed and modified from the German V-2. Generally the whole jump lasted about 15 minutes.

Alan Shepard was the first American in space suborbital flight in May 1961.
Gus Grissom was the second American in space on suborbital flight in July 1961.

The 3 days before the orbital flight the astronaut went through a special diet to minimize things happening during the flight :-).

John Glenn was the first American in the orbit in February 1962. It lasted about 5 hours (3 orbits).
Scott Carpenter was the second in the orbit in May 1962 and it lasted about 5 hours as well (3 orbits).
Wally Schirra spent about 9 hours (6orbits) in the orbit in October 1962.
Gordon Cooper was the first American to spent one day and 10 hours making 22 orbits in the orbit in May 1963.

May be you have noticed one missing name: Deke Slayton. He was grounded in 1962 by atrial fibrilation. But he got clearance to fly again in 1972, and he was assigned as the docking module pilot of the 1975 Apollo-Soyuz Test project. At age of 51 he became the oldest person in space at that time.
