The Mars Climate Orbiter was a part of NASA’s Mars expedition to explore Mars. It was launched after two spacecraft examined Mar. The purpose of this Orbiter was “to study climate of Mars and to serve as a communication relay” (ftp://ftp.hq.nasa.gov/pub/pao/reports/1999/MCO_report.pdf). It was meant to act as relay station with future Mars missions as well as coordinate with a future 2001 Lander mission. The orbiter was launched on December 11th and spent nine months traveling to Mars. At around September, the orbiter entered the Mar’s atmosphere the process of aerobraking was initiated. A process in which a spacecraft slows down by flying through a planet’s atmosphere. In other words, friction from the atmosphere slows down the spacecraft

With Apollo 11 being the first mission that set a precedent of the first human to land on the moon. A year later, Apollo 13 was the thirteenth mission of a series of mission that focused on the moon. The mission started on April 11, 1970. This was a mission’s core objective was on landing on the moon in the Fra Mauro area. The primary aim was to survey the region, deploy and activate an Apollo lunar surface experiment … develop a capability to work in a lunar environment and obtain photographs of candidate exploration sites” (http://www.history.nasa.gov/SP-4029/Apollo_13a_Summary.htm). This was supposed to be the third landing on the moon but almost ended in disaster as an explosion occurred on Apollo 13. This occurred 56 hours after launch thereby forcing the crew to abandon the mission and orbit around the moon and return safely to Earth. The mission was later transmitted to Apollo …show more content…
These conclusions were drawn from the data sensors in which corresponds with a drop in pressure in the tank once the explosion occurred. Consequentially, the command module started to lose power as the oxygen tanks and fuel cells were damaged. Furthermore, the stored oxygen was not only used for respiration for the astronauts but also used to generate electricity. At the end, a NASA investigation board determined the cause of the failed mission to be faulty oxygen tank number 2, which was exposed to wires that sparked the explosion. The extent of the damage is seen in figure XX. It was also concluded that the tank was damaged beforehand also may be resulted in the accident. Previously, the tank was accidently dropped about 2 inches and was settled that it did not suffer any damage. However, later tests found that the oxygen tank could not fully empty the tank, in which a “small tube used to fill and empty the tank of its super-cold contents had been damaged by the mishandling”( http://www.space.com/8193-caused-apollo-13-accident.html). Rather than address the problem, workers used a heater to drain the tank, the optimal temperature of the tank was 25°C but workers failed to notice that it has risen to 1000°C thereby
