While we were not watching, the Voyager 1 spacecraft underwent another surgery.

In August, V1 switched thrusters used for orientation control, because the fuel tubes in the thrusters had clogged up with residue.

To perform the switch, the thrusters had to be warmed by turning on its heaters while turning off another set for an hour.

All very tricky and risky operations, performed from 22.8 light-hours away on 1970’s era hardware.

Kudos again to the Voyager team.
