Interesting read ... The cause of failure of the Mars Observer is given ;-) The NASA report stated that the most probable cause of the loss of communications with the spacecraft on Aug. 21, 1993, was a rupture of the fuel (monomethyl hydrazine (MMH)) pressurization side of the spacecraft's propulsion system, resulting in a pressurized leak of both helium gas and liquid MMH under the spacecraft's thermal blanket.
This reminded me of a story by Dr Van ALLEN who said in an interview that he liked his finger and put it on the outside of the Mariner 10 spacecraft :-)
