Apollo 11 Flight Log, July 22, 1969: Firing Engines for Earth Return

The Apollo 11 crew went to sleep at 4:30 a.m. EDT with their spacecraft coasting away from the moon, monitored by controllers in Houston at Mission Control. Their sleep period lasted until about 1 p.m. EDT, shortly before the spacecraft passed the spot where Earth's gravity took over from that of the moon. That location was about 38,900 miles (63,000 kilometers) from the moon and 200,000 miles (322,250 kilometers) from Earth.

While examining the trajectory of Columbia in Mission Control, the team determined it was best for the astronauts to do a midcourse correction to bring them on the correct path to Earth. The astronauts fired Columbia's engines at 4:02 p.m. to readjust the flight. Five hours later, the crew did a short television broadcast to Earth, lasting about 18 minutes.
