(CNN) Voyager 2 was only expected to last for five years, but it's still operating 42 years after launch.

360 degrees to help calibrate its magnetometer, or magnetic field instrument. This is one of five instruments still operating on the probe. Yet Saturday, January 25, the probe did experience a bit of a hiccup 11 billion miles from Earth, according to NASA . The spacecraft was expected to make a scheduled maneuver and rotate360 degrees to help calibrate its magnetometer, or magnetic field instrument. This is one of five instruments still operating on the probe.

But data from Voyager 2 showed a delay in this maneuver, which also left two systems running on high power at the same time. In order to keep both Voyager 1, which also launched in 1977, and Voyager 2 going all this time, engineers have worked in the past to help maintain proper power usage by turning off systems.

Voyager 2's instrument snafu caused the probe to overdraw on its available power. That triggered the spacecraft's fault protection software routine, which responds if it senses that Voyager 2 is consuming too much energy.

As a result, the five scientific instruments on Voyager 2 were shut off. On Tuesday, engineers were able to shut down one of the systems using a large amount of power and turn the science instruments back on, according to NASA.
