Voyager 1 Just Fired Up its Backup Thrusters for the 1st Time in 37 Years
NASA's far-flung Voyager 1 spacecraft has taken its backup thrusters out of mothballs.
Voyager 1 hadn't used its four "trajectory correction maneuver" (TCM) thrusters since November 1980, during the spacecraft's last planetary flyby — an epic encounter with Saturn. But mission team members fired them up again Tuesday (Nov. 28), to see whether the TCM thrusters were still ready for primetime.
The little engines passed the test with flying colors, NASA officials said.
