NASA shuts down 49-year-old Voyager 1 instrument to keep it alive

Voyager 1 just powered down a nearly 50-year-old instrument to stay alive in deep space. The spacecraft is running critically low on energy, forcing NASA to make careful sacrifices to keep its mission going. Despite the shutdown, it continues to send back unique data from beyond our solar system. Engineers are now working on a bold plan that could extend its life — and possibly revive the instrument later.
