Project manager Suzanne Dodd said that Voyager 2 can keep functioning for 5 to 10 more years in this new region of space, though not with all its instruments operating. It is currently running at only 3.6 degrees Celsius, not much higher than the freezing point of hydrazine. Still, she’s set a personal goal of keeping at least one of the Voyagers going until 2027, making it a 50-year mission.
The solar system includes objects under the gravitational influence of the Sun, ie the Oort Cloud. It will be another ~300 years before either @NASAVoyager reaches the inner edge of that region, but both spacecraft are out of the solar bubble (heliosphere) & in interstellar space pic.twitter.com/OFzpmaBhCS
