Despite many worrisome hours, including periods of time when Apollo 13's crew members were unable to communicate with Mission Control, the astronauts were able to land in the Pacific Ocean. A positive conclusion to the mission occurred because people on the ground closely collaborated with people in space to repair what could have been a fatal problem.
The crew had to abort their moon landing, but that was a small price to pay for successfully returning to Earth.
