Satellite failure describes any malfunction or complete breakdown of an artificial satellite, affecting its operational capabilities or mission. Causes include...
A satellite failure occurs when an artificial satellite malfunctions or ceases to operate as intended, either partially or completely, thereby compromising its mission or operational capabilities.
Common causes include technical malfunctions (hardware/software), impacts from space debris, solar radiation, power system failures, propulsion system issues, and human error during design or operation.
Consequences range from disruptions to vital services like communication, navigation (GPS), and weather forecasting, to significant financial losses for operators and potential risks from uncontrolled atmospheric re-entry of debris.
Typically, orbital repair of satellites is not feasible once they fail. However, advanced in-orbit servicing technologies are being developed for refueling, repositioning, or minor repairs, though these are not yet widespread.
