None. The moon missions were launched by a Saturn 5 rocket carrying an Apollo space capsule. The space shuttles were used for earth orbit missions.
Columbiawas the first Space Shuttle that traveled to Earth orbit. .
The first space shuttle was launch in 1981. Space shuttle missions do not stay in orbit, they are designed to return to Earth after missions generally lasting 1-2 weeks.
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. See the Web Links to the left for further information.

The manned space program is just what it says. It's a program to send humans into space. Unmanned vehicles have the advantage in that they don't have to return to earth. That means they can go further and stay in space indefinitely. Manned missions however, need to return its cargo back to earth. Manned missions have the advantage in that if something goes wrong, they can usually fix it in space. If something breaks on an unmanned mission, they simply send up another spacecraft. Manned missions also have the added advantage in that people can observe things in space, while unmanned missions simply obey commands from their earth based masters.

Any information obtained from any space hardware during the mission reaches earth by radio. (That includes manned missions as well.)
