VOYAGER 1 (AND HALF ITS INSTRUMENTS) ARE BACK ONLINE(From: SkyandTelescope" )
Things are looking better for one of NASA’s longest running deep space missions. After a several-month period of problems, engineers have announced that the Voyager 1 spacecraft is not only back online but also transmitting useful data from two of four science instruments. Work is now underway to bring the remaining two instruments up to operational status.
...
The first test of this approach was to focus on code for the spacecraft's engineering data. That modification was done on April 18th. Voyager 1 is currently 163 astronomical units away from Earth, and a signal takes 22.5 hours (45 hours round trip) to reach the spacecraft. The team thus had to wait two days to see if the fix had taken hold. When they finally saw that it had worked on April 20th, they once again had access to the general status of the spacecraft.
Additional updates allowed the spacecraft to resume sending back science data on May 17th from two of its instruments. Voyager 1’s magnetometer and plasma wave subsystem are now back to returning useful data.
Engineers are currently working to get two other systems back online: the low-energy charged particle instrument and the cosmic ray subsystem.
We used to be able to make things work and work... Voyager 1 was from that time...
