What Went Wrong On Apollo 13 By: Ashwin S.

We just finished a movie called Apollo 13 because in the book we just read called Cosmic they get back to earth using the way Apollo 13’s crew got back to earth. I did some research and this is what I found out, that caused the problem on Apollo 13.

First off Mission Control had requested that the crew stir the oxygen tanks, a task required to prevent the oxygen ‘slush’ from stratifying. The Teflon-insulated wires that provided electricity to the stirrer motor were damaged, causing a large fire when electricity was passed through them. The fire heated the surrounding oxygen, increasing the pressure inside the tank above its nominal 1,000 PSI (7 MPa) limit, and causing the tank to explode. The cause of the explosion was unknown at the time, however, and the crew and Houston conjectured that a meteoroid had struck the SM or even the Lunar Module (LM).

This explosion caused damage to other parts of the Service Module, including, critically, the number one oxygen tank. Because the Command/Service Module(CSM) relied on the oxygen tanks to generate electricity, damage to number one tank meant that very little power was available for the spacecraft. The Command Module (CM) contained batteries for use during re-entry, after the SM was jettisoned, but these would only last about ten hours. Because this power needed to be saved for re-entry, the crew survived by using the LM, still attached to the CSM, as a “lifeboat”. The LM “lifeboat” procedure had actually been created during a training simulation (in the simulator) not long before the flight of Apollo 13.

This week in Language Arts class we have been watching as you can probably guessed from the title, Apollo Thirteen. It was about the story of the second trip to go walk on the moon and how it all went wrong. During the mission they had to complete the routine procedure of checking the pressure gauge and stirring the oxygen tanks. A faulty part in the tanks caused the tanks to explode, causing the entire side panel to be blown off into space and start leaking oxygen. After a huge gamble that saved the crew’s lives, they still needed to reenter. The ground crew was worried when the system did not show a visual of the spacecraft for over four minutes.They managed to get home after help from Ken Mattingly and everyone at mission and land in the South Pacific Ocean where they were picked up by the USS Iwo Jima aircraft carrier.

Apollo 15 and Al Worden by Cam

Right now I am reading a book called Falling to Earth and it’s by a man named Al Worden. This particular man is very interesting because of a few things. One of them is that he went to the moon. He was on the flight of Apollo 15 as the command module pilot. Most people, when they hear the name Mike Collins don’t know who he is. He was the CMP for Apollo 11. He was the one that stayed up in the command module while the lunar module went down with Neil and Buzz. Al did the same thing that Mike did but longer. Al also holds a record that no one else has broken. He made a spacewalk farther from Earth than any other person ever.  He went out to make a few repairs to their ship. I would tell you more but the book can do a better job describing than me.
