astronaut

Introduction of job:
Any people who travels in space is called an astronaut. The Russians call their space travellers cosmonauts. Most astronauts stay in space for only a few days, but some remain there for months in the ISS( International Space Station)
How do astronauts train for their mission?
They have flight training in jetplanes and flight simulators. Mission specialists rehearse mission procedures and experiments. They may train for EVA (extravehicular activities) submerged in water tanks, where conditions are similar to the weightlessness of space.

Description of job: On missions on orbit, a commander and pilot fly the spacecraft. On past missions, specialists have made observations, carry out experiments and, if necessary perform EVAs.

The People:
Neil Alden Armstrong (born August 5, 1930[1]) is an American aviator and former astronaut, test pilot, aerospace engineer, university professor, and United States Naval Aviator. He was the first person to set foot on the Moon.
Before becoming an astronaut, Armstrong was in the United States Navy and served in the Korean War. After the war, he served as a test pilot at the National Advisory Committee for Aeronautics (NACA) High-Speed Flight Station, now known as the Dryden Flight Research Center, where he flew over 900 flights in a variety of aircraft. As a research pilot, Armstrong served as project pilot on the F-100 Super Sabre A and C variants, F-101 Voodoo, and the Lockheed F-104A Starfighter. He also flew the Bell X-1B, Bell X-5, North American X-15, F-105 Thunderchief, F-106 Delta Dart, B-47 Stratojet, KC-135 Stratotanker and Paresev. He graduated from Purdue University and the University of Southern California.
A participant in the U.S. Air Force's Man In Space Soonest and X-20 Dyna-Soar human spaceflight programs, Armstrong joined the NASA Astronaut Corps in 1962. His first spaceflight was the NASA Gemini 8 mission in 1966, for which he was the command pilot, becoming one of the first U.S. civilians to fly in space. On this mission, he performed the first manned docking of two spacecraft with pilot David Scott. Armstrong's second and last spaceflight was as mission commander of the Apollo 11 moon landing mission on July 20, 1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spent 2½ hours exploring while Michael Collins remained in orbit in the Command Module. For his spaceflights, Armstrong received the Congressional Space Medal of Honor.


Armstrong served on two spaceflight accident investigations. The first was in 1970, after Apollo 13, where as part of Edgar Cortwright's panel, he produced a detailed chronology of the flight. Armstrong personally opposed the report's recommendation to re-design the service module's oxygen tanks, the source of the explosion.[100] In 1986 President Ronald Reagan appointed him to the Rogers Commission, which investigated the Space Shuttle Challenger disaster of that year. As vice-chairman, Armstrong was in charge of the operational side of the commission.[101]
