Investors commit quarter-billion dollars to startup designing “Giga” satellites - Ars Technica https://share.google/G6zF4HjqvgrSGJO4F

I think that we've seen a good deal of news lately about satellite traffic and how there is a good deal of it that is unencrypted

And then there was news of Scott Tilley in British Columbia, Canada who discovered that there were some satellites in a classified network that were sending data in the wrong direction

He has some incredible documentation on what he captured, and how he captured it using fairly common equipment that most geeky-type-folks would have lying around our labs.

I was able to replicate his setup and started capturing data just to see what I could find. I have to say that I was taken aback from the sort of thing that I was able to grab - again - completely unencrypted.

Skynet-1A: Military Spacecraft Launched 55 Years Ago Has Been Moved By Persons Unknown

In 1969 the UK launched Skynet-1A, a military communications satellite.

It stopped working due to hardware issues around 18 months after it started operating

At some point in the intervening years, the satellite has likely been moved – but nobody appears to know when, who, or why.
