Apollo 13 might not have returned to Earth, if NASA did not encounter, explore, and exchange new ideas. Apollo 13’s intention was to be the third mission to go to the moon. On the way to the moon apollo 13’s oxygen tank failed. This caused NASA to encounter, exchange, and explore new ideas, so that apollo 13 could safely return to Earth.What apollo 13 encountered help future spaceships improve how their oxygen tanks worked. Since apollo 13, there have been no reported oxygen tank failures on board spaceships. There were many events that lead up to the disaster aboard Apollo 13. During pre launch testing, the heater thermostat switch was closed and this caused a major design flaw. The teflon insulation on the wiring was damaged causing the wire to be exposed. Two days after liftoff, two of the three condition needed for disaster were present (Gene Kranz). The three conditions that are needed for an explosion are gaseous oxygen, damaged tank insulation, and a spark. Now all they needed was a spark. Finally inside tank two, when they started the cryo stir the third element was present, the spark which caused the explosion. After Apollo 13 changes were made to insure that no other spacecraft would have this issue. Since then there have been no reported oxygen tank failures. The odds of Apollo 13 returning to Earth was one in…show more content…
Spacecraft will use a planetary atmosphere to slow them down and enable aerocapture in order to save fuel to bring them into orbit. When a spacecraft enters a planetary atmosphere at a velocity significantly exceeding the speed of sound, a shock layer forms in front of the body. Heat shields help protect the spacecraft against the extreme heat that surrounds the spacecraft during reentry. When the electron density gets sufficiently high, such that it exceeds the critical plasma density of the link frequency, communications can be disrupted. This causes a
