Apollo 13 During a modification of Oxygen Tank No. 2 by NASA contractor, North American Rockwell, it was inadvertently dropped about 2 inches, which caused undetected damage to the interior assemblies. This damage eventually led the failure of the $400-million Apollo 13 mission. The crew of Apollo 13 was responsible for several scientific experiments that were to be carried out during the mission. Atmospheric electrical phenomena experiments were designed to "study certain aspects of launch-phase electrical phenomena." An opportunity to study large mass impact phenomena on the Moon was available with this mission. Instead of sending the third stage of the launch vehicle into solar orbit, as had been done on previous missions, the trajectory of the Apollo 13 S-IVB was designed to cause it to hit the lunar surface. Equipment set up during the Apollo 12 mission would have been used to record the seismic signals. The crew was also assigned to install a heat flow experiment designed to measure the amount of heat coming from the inside of the Moon. This data would be used to determine whether the Moon actually had a molten core. This would provide new insight on the internal structure of the Moon. The Apollo spacecraft (CM) was named Odyssey and the lunar module (LM), Aquarius. The CM was a conical pressure vessel with a maximum diameter of 3.9 m at its base and a height of 3.65 m. The CM was divided into three compartments, forward, aft, and the crew compartment. The forward compartment, in the nose of the cone, contained "the three 25.4 m diameter main parachutes, two 5 m drogue parachutes, and pilot mortar chutes for Earth landing." The aft compartment, at around the base of the CM, "contained propellan... ... middle of paper ... ...overheating occurred, burning insulation off electrical wiring. Because of that, the wires eventually short circuited and a $400-million mission was aborted." Bibliography: Compton, David.
