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 http://twitter.com/Voyager2.
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.
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."
