NASA is working to extend the life of Voyager 2. The space probe’s instruments can now operate until 2026.

NASA did what might be called a “life hack” on its Voyager 2 space probe, which means that all of the instruments on board the craft can work for a few more years. Voyager 2 left Earth more than 45 years ago, and NASA previously reported that Voyager will likely stop using all five instruments this year and send its observations back to Earth.

Now, however, scientists at NASA have redirected power from one of the spacecraft’s safety systems so that it can be used by the instruments aboard Voyager 2, which is why they believe all Voyager 2 instruments can operate until 2026. NASA writes in a press release:

Looking for a way to avoid shutting down a scientific instrument on Voyager 2, the team took a closer look at a safety mechanism designed to protect the instruments if the spacecraft’s voltage — the flow of electricity — changes dramatically. Because voltage fluctuations can damage the instruments, Voyager is equipped with a voltage regulator that turns on A backup circuit in such an event. The circuit has access to a small amount of power from the RTG (Radioisotope Thermoelectric Generator) intended for this purpose. Instead of retaining that power, the mission will now use it to keep science instruments running.”

Voyager 2’s amazing flight

Now located 20 billion kilometers from Earth, Voyager 2 is the only spacecraft operating outside the heliosphere of our solar system, along with its twin, Voyager 1. Originally, the idea was that the Voyager 2 mission would last four years and that it would observe Saturn and Jupiter during Aviation. Since then, NASA has expanded the Voyager 2 mission several times, and the craft has moved away from Earth. Since 2018, the craft has been in interstellar space.

Voyager 2Voyager 2 is a space probe launched by NASA on August 20, 1977, to study exoplanets and interstellar space beyond the heliosphere of the Sun. As part of the Voyager program, it launched 16 days before its twin, Voyager 1, on a trajectory that took longer to reach the gas giants Jupiter and Saturn but enabled more encounters with the ice giants Uranus and Neptune. Voyager 2 remains the only spacecraft to have visited any of the icy giant planets. Voyager 2 was the fourth of five spacecraft to achieve solar escape velocity, which allowed it to leave the solar system.
