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%. Now just 4 science instruments remain active to study the region outside our heliosphere. See graphic below.

Note that the plasma science instrument on Voyager 1 failed and was turned off in 2007.
