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.

    Here are some key metrics on the twin Voyager spacecraft.

    Let’s take a moment to marvel at the 1970s technology in these spacecraft - computing hardware/software, instruments, RTGs, thrusters, etc. - most of which are still operational after 47 years in the harsh environment of space, 22:53 and 19:04 light hours away resp., with no maintenance or repairs, just workarounds around few failures, quietly exploring where no spacecraft has explored before.
