> The team started by singling out the code responsible for packaging the spacecraft’s engineering data. They sent it to its new location in the FDS memory on April 18. A radio signal takes about 22 ½ hours to reach Voyager 1, which is over 15 billion miles (24 billion kilometers) from Earth, and another 22 ½ hours for a signal to come back to Earth.

Talk about a slow feedback loop! And I get frustrated when I need to push code to a repo to test things in CI...



My internet is operating at about 1/100 normal speed today. It feels a bit like I've been remoting into a machine on Mars.


How much data can you send in a single radio single? I assume it's not TCP/IP


Downlink from Voyager to Earth is currently 40 bits/s but can be up to 160 bits/s. The signal is received at -160dBm or around 100 _zeptowatts_ (1e-22 kW).


Have you investigated this or are you just asking? I imagine if you wish to learn the answer it is a few simple searches away. And by “imagine” I mean, it is.


You can get raw bitrate numbers, not so much about the way transmissions are formatted.


Posting a question in a forum has its benefits though. A bunch of drive by folks end up picking up information they would never have gone through the trouble of researching themselves.


Hopefully they have a few local benches to iterate on for testing.


So there is something with a worse ping than IP over Avian Carriers.
