On this day in space: April 9, 1959: NASA Introduces the 'Mercury 7' Astronauts

On April 9, 1959, NASA introduced its very first astronaut class. This dashing group of young men is known as the Mercury 7.

The seven Mercury astronauts were (from left) Wally Schirra, Alan Shepard, Deke Slayton, Gus Grissom, John Glenn, Gordon Cooper and Scott Carpenter.

Some of the pilots weren't too happy about this. But the rest of the country paid no attention to that, and the Mercury 7 instantly became national heroes. In 1961, Alan Shepard became the first American to fly to space, followed by Gus Grissom.

Then in 1962, John Glenn became the first American to orbit the Earth. After that, Scott Carpenter, Wally Schirra and Gordon Cooper all completed orbital missions as well. Deke Slayton, the only Mercury 7 astronaut not to fly a Mercury mission, later flew on the historic Apollo-Soyuz mission, the first joint flight by two countries: the United States and Soviet Union.
