Also keep a close eye on the Opensource SatDump project. That's a group of (mostly ham, but not all of them) radio enthusiasts that are listening to all kind of science satellites. They managed to decode many of them.
They are far far beyond the old 137MHz analog NOAA stuff. Collecting crazy broadband from S- or X-band is no challenge for them.

I wouldn't say it's mostly HAMs. More that it's a small community of largely European teenagers and 20 somethings. I say that as someone who found their way into the hobby back during covid and now have up and running L, S, and X band setups.
Twitter, Derek's SGC's discord (https://discord.gg/7fFFzNsPEF), and Alan's Matrix server are the three main places to find imagery. That and people's own personal web sites. Here's mine.
https://geostation.io/
Please don't criticize my site too much, I've not updated it for ages and historically I used it as a place to dump output from my geostationary satellite stations.

And I guess the other thing to mention is that x band data often adds up real quick, so it's nowhere near as prevalent in full resolution online. I'm basically surrounded by forest and only get sync on Chinese LEO sats at maybe 35°+ north and then lose sync due to the forest at ~30° elevation south. My resulting true color composites are routinely 400-500MB.
Someone with clear LoS to either horizon can easily produce composites that are over 1GB per image.

> 1) Do they post SatDump data somewhere?
Don't know.
> 2) (I doubt it but) Is it under a free license?
SatDump is GPLv3

I love Marks posts. They are always starting from absolute nothing and then just builds up everything, so you can replicate everything he does. It's absolutely amazing writing and very educational.

I am loving the recent spat of open satellite data!
