Which booster was used to send the 1st American into orbit?
John Glenn John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was a United States Marine Corps aviator, engineer, astronaut, and United States Senator from Ohio. In 1962 he became the first American to orbit the Earth, circling it three times.
STS-62-A STS-62-A was a planned Space Shuttle mission to deliver a reconnaissance payload (Teal Ruby) into polar orbit. It was expected to use "Discovery". It would have been the first manned launch from Vandenberg Air Force Base, California, and the first manned mission to go into polar orbit. The mission designation, 62-A, meant: 6=fiscal year 1986, 2=Vandenberg (1=Kennedy Space Center), and A=first flight in that fiscal year.
