NASA Voyager update - on Sept 26, one more instrument aboard Voyager 2 was turned off to conserve power - the plasma science instrument.
Over the 46 years since launch, Voyager instruments have gradually been shut off as power levels have declined by over 50%. With 4 science instruments left, the Voyagers will continue to boldly go where no spacecraft has gone before.
Note that the plasma science instrument on Voyager 1 failed and was turned off in 2007.
