Still, the lean team of engineers and scientists working on the Voyager program at NASA’s Jet Propulsion Laboratory are taking steps to eke out every bit of life from the only two spacecraft flying in interstellar space, the vast volume of dilute gas outside the influence of the Sun’s solar wind.

“These are measures that we’re trying to take to extend the life of the mission,” said Suzanne Dodd, Voyager project manager at JPL, in an interview with Ars.

This problem first cropped up in 2022, when engineers noticed the computer responsible for orienting the Voyager 1 spacecraft was sending down garbled status reports despite otherwise operating normally.

NASA says the buildup is “becoming significant” in some of the lines, so engineers beamed up fresh commands to the spacecraft in the last few weeks to allow the probes to rotate slightly further in each direction before firing the thrusters.

With these steps, engineers expect the propellant inlet tubes won’t become completely blocked for at least five more years, and “possibly much longer,” NASA said.

“This far into the mission, the engineering team is being faced with a lot of challenges for which we just don’t have a playbook,” said Linda Spilker, Voyager project scientist at JPL, in a statement.
