To conserve power and to extend the life of the mission, one more instrument on the venerable Voyager 1 probe is being shut down - the Low-energy Charged Particles experiment (LECP).
The shut-off command was sent on April 17; it will take 2 days to receive confirmation.
The table below shows the status of the major instruments on the two spacecraft.
The 49 year old probes could operate with at least one science instrument into the 2030s.
