[space] NASA’s Voyagers Grow Weaker Each Year … How the Voyager probes are still running after 40 years in space. ‘Engineers also shut off a heating component that keeps one of Voyager 2’s instruments warm enough to function in the frigid cold of space. Turning off a heater buys the mission four watts, the same amount it loses in a year. After months of deliberation, scientists decided that sacrificing this instrument, which last year helped confirm that the spacecraft had left the solar system, was worth it. Unlike the others, this instrument can point only in certain directions. Some other instruments have, incredibly, tolerated the loss of their heaters, sometimes for years.’
