<P> After being sent toward the Moon by the Saturn V 's upper stage , the astronauts separated the spacecraft from it and traveled for three days until they entered into lunar orbit . Armstrong and Aldrin then moved into the lunar module Eagle and landed in the Sea of Tranquility . They stayed a total of about 21.5 hours on the lunar surface . The astronauts used Eagle 's upper stage to lift off from the lunar surface and rejoin Collins in the command module . They jettisoned Eagle before they performed the maneuvers that blasted them out of lunar orbit on a trajectory back to Earth . They returned to Earth and landed in the Pacific Ocean on July 24 . </P>
