Failure of a payload component, typically an antenna or reflector, that cuts or wipes out a satellite's commercial capacity without destroying it.
A payload failure hits the equipment that generates a satellite's commercial value, most often a deployable antenna or reflector, without necessarily affecting the platform itself, the bus, which keeps functioning. This type of failure is especially feared by insurers because it destroys nothing visible: the satellite stays in orbit, operational on paper, yet unable to deliver all or part of the service it was insured for, which raises the question of how to characterize the loss and at what threshold of lost capacity a claim is triggered. In July 2023, Viasat announced that a hardware anomaly on the reflector of its newly launched ViaSat-3 F1 satellite was preventing full antenna deployment and would cut the mission's planned capacity by several tens of percent. The loss led to what is considered the largest claim ever recorded on a single satellite, on the order of $420 million, mobilizing a pool of space reinsurers and reviving the debate over pricing for very high-capacity launchers and satellites, whose failure concentrates an outsized financial risk on a single event.
