The first one to reach outer space in the Man In Space Soonest program was which Captain in the United States Air Force, an American World War II pilot, an experimental physicist, and NASA test pilot?
Joseph A. Walker Joseph Albert "Joe" Walker (February 20, 1921 – June 8, 1966) flew the world's first two spaceplane flights in 1963, thereby becoming the United States' seventh man in space. Walker was a Captain in the United States Air Force, an American World War II pilot, an experimental physicist, a NASA test pilot, and a member of the U.S. Air Force Man In Space Soonest spaceflight program. His two X-15 experimental rocket aircraft flights in 1963 that exceeded the Kármán line – the altitude of 100 km , generally considered to mark the threshold of outer space – qualified him as an astronaut under the rules of the U.S. Air Force and the Fédération Aéronautique Internationale (FAI).
STS-41-G STS-41-G was the 13th flight of NASA's Space Shuttle program and the sixth flight of Space Shuttle "Challenger". "Challenger" launched on 5 October 1984, and conducted the second shuttle landing at Kennedy Space Center on 13 October. It was the first shuttle mission to carry a crew of seven, including the first crew with two women (Sally Ride and Kathryn Sullivan), the first American EVA involving a woman (Sullivan), the first Australian-born person to journey into space and the first astronaut with a beard (Paul Scully-Power) and the first Canadian astronaut (Marc Garneau).
