First for America: February 20, 1962, Glenn orbits Earth E-mail

On February 20, 1962, the United States launched Friendship 7 with NASA astronaut John Glenn onboard. The Mercury-Atlas 6 mission, launched with an Atlas 109-D launch vehicle, was the first American attempt to place an astronaut in orbit.          


After launching from Launch Complex 14 (LC-14) at 9:47:39 am EST (14:47:39 UTC) from Cape Canaveral, Florida, Glenn orbited the Earth three times at a perigee of about 100 miles (159 kilometers) and at an apogee of about 162 miles (265 kilometers).

Previous to Glenn’s flight the Russians had already placed cosmonaut Yuri Gagarin in orbit with Vostok 1 on April 12, 1961, and, later, cosmonaut Gherman Titov in orbit on August 6, 1961.

It was a race to the Moon, and the Russians were ahead.

During the flight the spacecraft's computer had problems with controlling the spacecraft, specifically with the stabilization and control system, so Glenn took over manual piloting.

He also had a problem with the heat shield. Sensors indicated it was loose, which could be a major problem if it fell off before or during descent into the Earth’s atmosphere.

The retro pack, which normally was ejected, was left on to help make sure the heat shield would stay in place.

Glenn successfully took care of the problems and Friendship 7 splashed down in the Atlantic Ocean about 40 miles (60 kilometers) away from the targeted landing area.

The destroyer USS Noa picked up Glenn and the capsule a few minutes later.

Glenn’s ride into space was a giant leap for the United States to become the first nation to step foot on the Moon, which was only seven years away.

Glenn returned to space thirty-six years later when he was a crew member of the space shuttle Discovery and STS-95, which orbited the Earth from October 29 to November 7, 1998.
