Voyager 2 is gathering science data again after recovering from a glitch in interstellar space

All five remaining instruments on NASA’s venerable Voyager 2 spacecraft are back to gathering science data after power overuse in late January interrupted the probe’s operations.

NASA made the announcement yesterday (March 3), over a month after the incident occurred. Troubleshooting for the spacecraft is a slow process because of its distance from Earth; it takes 17 hours for each command to reach the probe and for data indicating its efficacy to reach engineers.

“Voyager 2 has returned to normal operations following the anomaly on Jan. 25, 2020,” NASA officials wrote in a statement. “The five operating science instruments, which were turned off by the spacecraft’s fault protection routine, are back on and returning normal science data.”

On Feb. 14th, 1990, the Voyager 1 probe snapped an image of Earth. The probe was more than 4 billion miles away from Earth at the time. Druyan, Carl Sagan’s co-author and widow, talks about how impactful the image is on humanity

Voyager 2, like its twin Voyager 1, launched in August 1977 and has been exploring ever since. Such extensive space travel takes its toll; as the spacecraft have long exceeded their mission expectancy, engineers have needed to improvise ways to keep the probes going, particularly as their power supplies dwindle.

The January problem occurred when Voyager 2 missed a spin maneuver to calibrate its magnetic-field instrument. That glitch left two power-hungry systems on simultaneously; the spacecraft recognized the risk of the situation and triggered a preprogrammed fault-protection mode.

Since then, mission engineers have been working to turn off the power-sucking systems and to get Voyager 2’s five remaining science instruments back to work. Those instruments are helping scientists understand what happens beyond the heliosphere, the bubble of space influenced by our sun. Voyager 2 left that bubble in November 2018, entering interstellar space.
