Not baud, but actual data rate returned:

https://voyager.jpl.nasa.gov/mission/science/

Science data are returned to earth in real time at 160 bps

Imagine the ping & jitter.....oh...god......

[–] Cocodapuf@lemmy.world 0 points 5 months ago* (last edited 5 months ago)

The ping is about 180,000,000 ms

Not great for games...

The latency to Voyager 1 is apparently a bit under 23 hours, so yeah, that's gonna be painful.

I'd guess that the jitter is probably zero.

Like, if they can pull data in realtime, I assume that they've chosen an encoding with enough redundancy that data can get through reliably at that rate. Because of the latency, they'd have to have a huge buffer if they wanted to have some protocol that required frequently requesting retransmits.

You could play chess or other turn based games. Imagine playing Alpha Centauri connected to a space probe... They should integrate this for the next probe.

As long as they add Doom as well.

That "real time" on out of earth scale always boggles my mind. Technically it is as fast as it possibly could, knowing that radio waves travels at the speed of light. But damn, that light has to travel for a long time before arriving so "real time" data that arrives is technically "quite old" data.

As far as it is, it's still just under one day at light speed.
