Spacecraft passivation
Web13. dec 2024 · 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. [1] 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. WebFinally, a spacecraft can be allowed to reduce its orbit by atmospheric drag, resulting in an uncontrolled reentry and impact on an unpredictable portion of the Earth’s surface. …

WebDuring launch a satellite is exposed to high levels of acoustic noise, vibration and transitory G forces, potentially causing stress corrosion in susceptible alloys or composites. Pyrotechnic shocks are also triggered as secured satellite elements such as antennas are deployed once in orbit. Web• be passivated after re-orbiting phase, in order to reduce explosion risk: the pressure must be lowered as much as possible in every spacecraft element. Propellant tanks are mainly concerned with passivation: they must be emptied, so thrusters have to be activated, which creates an impulsion and has an impact on the orbit of the spacecraft.
Web1. nov 2024 · Host spacecraft designed for self-passivation. In the basic PMD module case, the host spacecraft needs to be passivated by ground operators according to its own decommissioning plan. It is considered to be designed for passivation and thus, be compliant to the space debris mitigation guidelines mentioned before. Webpassivation and applicable to most European spacecraft.
