dos.step 1.step one. Background: For the 1998, NASA launched the latest MCO with the aim out-of gathering guidance to allow most readily useful understanding of the fresh Martian climate. During the b). The newest trajectory of your own spacecraft ended up being improperly computed, and therefore meant the spacecraft got in fact come orbiting far nearer so you can Mars than simply ended up being directed evoking the place probe in order to disintegrate regarding the planet’s environment (NASA, 2009).
Detail: An investigation try presented from the MCO Mishap Data Board to know very well what had was the cause of mistake hence lead to the exhaustion of one’s $125 billion area probe
dos.step 1.2 nepal kvinnor. The first declaration (NASA, 1999b) create following the analysis explained the main cause or any other tall factors you to contributed to the area probe loss.
dos.step 1.step 3. Thruster performance analysis got provided by software created by a keen outside specialist, when you look at the English equipment of pound-seconds. This was against the documentation in position – App Screen Specs (SIS) – and this intricate that show shall be offered inside the metric tools. This new navigation party from the NASA’s Jet propulsion Lab mistook these records as actually throughout the requisite metric systems of Newton-moments. Which resulted in the fresh new problems regarding the spacecraft’s trajectory calculations.
2.1.cuatro. The root cause, even if very important, was not considered to-be the actual only real factor inducing the MCO losings. This is since “enough techniques are usually in place on plans to capture such errors before they become important to goal achievement. Unfortunately getting MCO, the main cause was not caught by the procedure into the-added the brand new MCO enterprise”.ادامه خواندن
