Apollo 13 Problem Solving

"You know, that's, that's a significant G&C.It looks to me looking out the ahh, hatch that we are venting something," someone said.That was the portion of the spacecraft that would take the astronauts to the Moon.Once this was completed, the third stage was driven out along a collision course with the Moon.

In order to compensate, controllers burned the other four engines an additional 34 seconds.Then, the third stage engine ired for an extra nine seconds during its orbital insertion burn.Fortunately, this all resulted in a mere 1.2 feet per second greater speed than planned.Despite these problems, the flight went ahead and things seemed to go smoothly.entered the Lunar corridor, the command service module (CSM) separated from the third stage and maneuvered around to extract the lunar module.The technicians in Houston were having the same concerns.The only chance they had of saving the crew of Apollo 13 was to shut down the CM entirely to save their batteries for reentry.At first, they thought it was a practical joke previously played by Fred Haise. Seeing the expression on Jack Swigert’s face, Jim Lovell knew immediately that there was a real problem and hurried into the CSM to join his lunar module pilot. Alarms were going off as voltage levels of the main power supplies were dropping rapidly.If power was completely lost, the ship had a battery backup, which would last for about ten hours. Looking out a port, the astronauts saw something that gave them another concern.Apollo 13 was a mission that tested NASA and its astronauts to the hilt.It was the thirtheenth scheduled lunar space exploration mission, scheduled for liftoff at the thirtheenth minute after the thirteenth hour.
