WebPassivation During passivation, all latent energy reservoirs of a satellite or orbital stage are depleted to prevent an accidental post-mission explosion. Such passivation measures … The passivation of a spacecraft is the removal of any internal energy contained in the vehicle at the end of its mission or useful life. Spent upper stages are generally passivated after their use as launch vehicles is complete, as are satellites when they can no longer be used for their design purpose. Internally stored energy generally takes the form of unused propellant and batteries. In the past, s…
