Another day, another problem with Voyager 1, solved

20 September 2024

Data the nearly fifty-year old deep space probe was returning to Earth earlier this year, was getting all scrambled up. But dutiful mission controllers sorted that out. This despite Voyager 1 being so far away that it’d take a day to reach, assuming we had a vessel that could travel at the speed of light.

More recently, Voyager 1 has been having have trouble using correcting thrusters that keep the probe’s antenna pointed at Earth. Fuel pipes to the aging thrusters have begun to clog up, rendering them inoperative. Mission controllers, at the Jet Propulsion Laboratory, in California, however have been able to re-activate another set of thrusters — unused in decades — and effect a fix.

As a result of its exceptionally long-lived mission, Voyager 1 experiences issues as its parts age in the frigid outer reaches beyond our solar system. When an issue crops up, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have to get creative while still being careful of how the spacecraft will react to any changes.

If you want a tricky problem solved, ask a mission controller from one of the automated space missions to help. And of course Apollo 13.
