The three main space programs developed for human space travel and moon missions are NASA (United States), Soviet space program (USSR), and the Apollo program (United States), which was a part of NASA focused specifically on landing astronauts on the moon.
Currently, the farthest a human has traveled into space is about 400,000 kilometers. That is the distance from the Earth to the Moon.
