El Borscht: The fact that we are still in touch with the Voyagers weirds me out in a really good way


I feel like even if there's no more science to be gained from it we should spend the money to keep in contact as long as there's a signal coming from them, just because it's such an incredible achievement to have something that far out with the technology available at the time of their launch.

Keeping that connection going is like maintaining a monument to the achievement.

Time to expand the deep space network.

And in case you're curious about what the network is doing in real time

I hereby demand that I be given a Fark account: Worth noting that the Deep Space Network was originally built as the Manned Space Flight Network, and was built to support the Apollo missions. And I'm certain that the DNS charter included a phrase along the lines of "oh yeah if we ever do go back to the moon or farther, you'll be required to grant absolute priority to the lunar/martian manned mission comms.

The Lunar Reconnaissance Orbiter was going to send back so much data that they built their own receiving stations for it, because DSN couldn't given them anywhere near the antenna time they needed without compromising the ability to talk to other missions.



The cost three new dishes (i.e. one each for California, Australia, and Spain) would be a rounding error when compared to either SLS or Orion. And they would be useful to have as the network could use more bandwidth even if Artemis did not exist. And when the Moon is below the horizon, a dish can talk to other missions.

All of this right here. I find it amazing that we have two man made objects that have left the solar system, and soon(ish) to be three.

They need to upgrade their hardware.

And they used optical, for a higher bit rate (622MBps).  And NASA continues to experiment with optical; their current TBIRD project is intended to do terabit rates from low earth orbit.  We may see a lot more optical downlinks coming.
