Apollo 13 (as-508): Houston, We Have A Problem. :: essays research papers

Apollo 13 (AS-508) Houston, we get shoot a problem.The Apollo 13 mission was put uped at 213 p.m. EST, April 11, 1970 fromlaunch complex 39A at Kennedy Space Center. The space vehicle crew consisted of mob A. Lovell, Jr. commander, John L. Swigert, Jr., command module pilot andFred W. Haise, Jr. lunar module pilot.The Apollo 13 Mission was planned as a lunar landing mission but wasaborted en route to the moon later on well-nigh 56 hours of flight due to loss ofservice module cryogenic atomic number 8 and consequent loss of capability to generate galvanic power, to provide type O and to produce water.Spacecraft systems performance was nominal until the fans in cryogenicoxygen army ice chest 2 were turned on at 555318 ground elapsed time (GET). astir(predicate) 2seconds after energizing the fan circuit, a short was indicated in the currentfrom displace cell 3, which was supplying power to cryogenic oxygen tank 2 fans.Within several additional seconds, two separate shorted co nditions occurred.Electrical shorts in the fan circuit ignited the electrify insulation, causingtemperature and insistency to increase within cryogenic oxygen tank 2. Whenpressure reached the cryogenic oxygen tank 2 relief valve full-flow conditionsof 1008 psi, the pressure began decreasing for about 9 seconds, at which timethe relief valve belike reseated, causing the pressure to rise againmomentarily. About a tail assembly of a second later, a vibration disturbance wasnoted on the command module accelerometers.The next series of events occurred within a atom of a second betweenthe accelerometer disturbances and the data loss. A tank berth burst, because ofheat, in the vacuum jacket pressurizing the annulus and, in turn, causing theblow-out rechewed food on the vacuum jacket to rupture. Some mechanism in bespeak 4 combinedwith the oxygen buildup in that bay to cause a rapid pressure rise whichresulted in separation of the outer bloodshed. The panel struck one of the dishes ofthe high-gain antenna. The panel separation shock closed the fuel cell 1 and 3oxygen reactant shut-off valves and several propellant and helium isolationvalves in the reaction control system. Data were lost for about 1.8 seconds asthe high-gain antenna switched from narrow beam to wide beam, because of theantenna creation hit and damaged.As a result of these occurrences, the CM was supply down and the LM wasconfigured to supply the necessary power and other consumables.The CSM was powered down at approximately 5840 GET. The surge tank andrepressurization package were isolated with approximately 860 psi residualpressure (approx. 6.5 lbs of oxygen total). The primary water glycol system was
