Engineers have turned off Voyager 2's plasma science instrument to conserve power as it became less useful due to its orientation in interstellar space.
NASA stated, 'The most useful data from the fourth cup comes only once every three months,' influencing the decision to disable the instrument.
The spacecraft's operational science instruments will continue to gather data into the 2030s, despite the ongoing decay of its power source.
The switch-off command has resulted in only four instruments remaining active on Voyager 2, matching its sibling probe, Voyager 1.
