The Mercury missions were the first manned missions by the US into space. In a series of sub-orbital and orbital flights, they investigated the effects on humans of space travel and explored many of the unknown orbital and engineering mechanics. The first American in space, Alan Shepard, and the first American to orbit the earth, John Glenn, were the most visible accomplishments of the project. They were followed by the Gemini missions, the curtain raiser to the Apollo moon landings.
