NASA uses unique trick to save Voyager 1

Considered “dead” since 2004, Voyager 1's thrusters were unexpectedly successfully restarted at the farthest distance humans have ever intervened from Earth.

This system was turned off in 2004 due to a power outage of the heater, forcing Voyager to use its auxiliary thrusters for 20 years. (Photo: NASA)

When the boosters deteriorated and were at risk of failure, NASA was forced to risk reactivating the old boosters. (Photo: NASA Science)

The plan was based on the assumption that the heater was not broken but simply disabled by an electrical circuit failure. (Photo: Jet Propulsion Laboratory - NASA)

The engineering team deviated the ship from its guidance to activate the self-righting system, waking up the main thruster. (Photo: New Atlas)

After more than 23 hours of waiting for a response, they confirmed that the system was back up and running. (Photo: TwistedSifter)

This is considered an unprecedented technical feat in space history. (Photo: IFLScience)
