SPACE: NASA Power Hack Extends 45-Year Voyager 2 Mission Even Longer.
At 12 billion miles (20 billion kilometers) from Earth, Voyager 2 is so far that it takes more than 22 minutes for NASA’s signals to reach the probe. With its power gradually diminishing, mission planners thought they might have to shut down one of its five scientific instruments next year, but a newly implemented plan has resulted in a welcomed delay.
A recent adjustment, in which the probe redirects a tiny amount of power meant for an onboard safety system, means all five scientific instruments aboard Voyager 2 can stay active until 2026, according to a NASA Jet Propulsion Lab press release. There’s a modicum of risk involved, as the affected system protects Voyager 2 from voltage irregularities, but NASA says the probe can now keep its science instruments turned on for a while longer.
Plus: “Although the spacecraft’s voltage will not be tightly regulated as a result, even after more than 45 years in flight, the electrical systems on both probes remain relatively stable, minimizing the need for a safety net.”
That’s one well-built probe.
