The Low Energy Charged Particle instrument science team confirmed that the spacecraft had acquired the kind of information it needed, and mission planners gave Voyager 1 the green light to do more rolls and longer holds. There will be five more of these maneuvers over the next seven days, with the longest hold lasting three hours 50 minutes. The Voyager team plans to execute a series of weekly rolls for this purpose every three months.

Still maneuvering and returning science 33 years into the mission!

What is the umsf flyby spacecraft symbol for

????

Yep, and once again no mention of the role of the Deep Space Network

It's incredible to appreciate that we are still receiving signals from these two venerable spacecraft.
Their remoteness is highlighted by the current OWLT for the signals to reach Earth - 16 hrs 7mins for Voyager 1 and 13hrs 12mins for Voyager 2.
Signal strength for both is down to around -160dbm through the Network's big 70-metre antennas.
Literally listening to a whisper from space!!

Remember to follow the Voyagers on Twitter.
I still find it amusing that only Voyager 2 'tweets'. Apparently that upgrade wasn't sent out to Voyager 1

Wow! I would have guessed that was impossible, but it looks like they expect enough power to use the gyros until ~2015. Amazing. They're still working 21 years after the pale blue dot photos.

Wasn't 2 launched first? Always stealing the show.

I learned today - it's not an official NASA account.

Which stars are both Voyagers using nowadays for navigational purposes?
During their long 1980s cruise phases, it looks like Voyager 1 mainly used "Alpha Centauri" (constellation Centaur) while Voyager 2 used "Canopus" (southern constellation Carina)...

"Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft. Confirmation was received today that the spacecraft accepted the commands. The change will allow the 34-year-old spacecraft to reduce the amount of power it requires to operate and use previously unused thrusters as it continues its journey toward interstellar space, beyond our solar system."
