Colonel Guion S. Bluford, Jr. USAF
Guion "Guy" Bluford, Junior (born November 22, 1942) is a retired Colonel, from the United States Air Force and a former NASA Astronaut. He participated in four flights of Space Shuttle between 1983 and 1992. In 1983, as a member of the crew of the space shuttle Challenger on mission STS-8, Bluford became the first African American in space. (Note that the first person of African ancestry in space was the Cuban cosmonaut Arnaldo Tamayo Méndez.)

Arnaldo Tamayo Méndez (born January 29, 1942) was the first Cuban cosmonaut and the first person from a country in the Western Hemisphere other than the United States to travel in outer space. He was also the first Hispanophone and first person of African ancestry in space.

U.S. Air Force Lieutenant Colonel Guion S. Bluford becomes the first African American to travel into space when the space shuttle Challenger lifts off on its third mission. It was the first night launch of a space shuttle, and many people stayed up late to watch the spacecraft roar up from Cape Canaveral, Florida, at 2:32 a.m.
