THE JOURNEY HOMEArmstrong and Aldrin stayed on Moon for just more 21 hours-two-and-a-half hours of which were spent outside the Lunar Module exploring and conducting scientific experiments. At 1:53 pm on July 21 the astronauts lifted off from the Moon in the module's ascent stage and then rendezvoused with Collins and the orbiting spacecraft. The three explorers fired away from lunar orbit on July 22 and returned to Earth on July 24.
