Transcript of Apollo 13

Apollo 13 By: Heather Cichowic A Fateful Mission Three men were finally chosen to command this expedition. They were James A. Lovell Jr., John L. Swigert Jr.,
and Fred W. Haise Jr. The first command modulale pilot, Thomas K. Mattingly II, had to be replaced since he had been exposed to the German Measles. This was 72 hours prior to the launch schedule. John L. Swigert, Jr. replaced Mattingly. Bad Things
Are Happening This first thing to go wrong was Mattingling with the Measles After that people just started to get more and more superstiuous about it. This was Apollo 13!! Break-down of an Apollo Spacecraft About 56 hours into flight time damage occurs to the module cryogenic oxygen chambers, soon after the ability to generate power, water, and have air flow was lost in the CM. NASA tells them to abort the mission A later study of Mattingly found out that he did not have the Measles afterall. This would be the only Apollo mission NASA ever aborted. Getting Back Home There was a way to get beck home. But it was a risky one. They would have to travel back to the freezing cold lunar module. It was only supposed to fit 2 people for two days. But they had to make it last for 3 people and 4 days The crew would have to swing around the dark side of the moon This would take the already cold lunar module to almost 38 degrees Over the length of the trip the entire crew lost close to 32 pounds, about 50% more than what other teams lost The Landing The crew could not enter Earth's atomospere in the lunar module So four hours before they landed the crew had to get rid of the service module, which also got rid of the Lunar Module An intense moment during the return home was powering up the command module from its long sleep. All of the panels were covered with condensation Sources http://www-pao.ksc.nasa.gov/history/apollo/apollo-13/apollo-13.htm There was a risk of short circuting, but thankfully none happened Soon they splashed right down into the Pacific Ocean close to Samoa It was amazing that they even survived the journey back home By: Heather Cichowic Take Off Apollo 13 was launched from the Kennedy Space Center, Florida on April 11, 1970 at 2:13 PM But during the launch the second stage inboard engine shut down too early Once they were caught in the orbit they were fine and it went as planned After they filmed a 49-minute TV broadcast show about Apollo 13 and their experiences was when the real trouble started. Ground teams had to work fast to find another way to power the CM's batteries, these had to work since it was needed to reenter Earth They came up with a plan to take some of the energy from the LM to charge the CM's batteries, it had to be just enough to survive in the LM yet have enough to get back home
