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.
The Geminii program
The second manned space program was the Gemini program, conducted by NASA between 1961 and 1966. Gemini aimed to develop space travel techniques for missions to the Moon and later served as a bridge between the Mercury and Apollo programs.
Gemini
The Mercury Program was the first manned space flight program,
The first U.S. manned space program was called Project Mercury. It aimed to put a human in orbit around Earth and was active from 1958 to 1963.
The first manned space flight was by the U.s.s,R in the Sputnik.
N.A.s.A controls all of the U.s.A Space programes.

Mercury, Gemini, and Apollo.
Project Mercury was the first manned US space program, consisting of six flights between 1961 and 1963. Of these, two were sub-orbital flights while the last four all completed at least one orbit of the Earth.
The second American manned space program was Project Gemini. It aimed to develop space travel techniques in preparation for the Apollo program, which aimed to land humans on the Moon. Gemini missions tested rendezvous and docking procedures, long-duration spaceflights, and spacewalking capabilities.
The second American-manned space program was Project Gemini. It ran from 1961 to 1966 and aimed to develop space travel techniques necessary for the Apollo missions to the Moon. Gemini spacecraft carried two astronauts and conducted various maneuvers and experiments in space.
