The Right Stuff
The first manned space station was Salyut 1, launched by the Soviet Union in April 1971.
The first US man in space was John Glen in Friendship 7. He orbitted the earth in space but never went out into space. But the first man technically considered to be put in space by the US was Alan Shepard aboard the Freedom 7 on a sub-orbital flight. Hope this helps.
The second American space program aimed at making further progress toward manned exploration of the Moon was the Gemini program.
