What? No, exactly the opposite. It's very easy to jam radio signals and much harder to cut wires. There's a reason the drones on the front lines in Ukraine are dragging fibre optic lines these days.

There's probably so many ways to get around that with space based technology. I can quickly imagine several methods. It depends on what the system is for which might be a good method to use.

Method 1: same as how u2 planes dumped their data: air drop physical media containing data and catch it in the air.

Method 2: laser based emission to specific detectors.

Method 3: baseball style communication: station is under observation and manipulates in some way to serve as a signalling language.

Method 4: numbers station

Method 5: bill yourself as an isp and have some coded syntax that can be supplied in plain sight with the rest of isp traffic.

Method 1 runs into the problem of how to replace that media. The DC is in space so it's not like with U2 planes where they landed. Also, I think you mean the keyhole satellites and not U2 planes, since a plane lands at a secure site and can offload media then.

Method 1: Sure datacenters with latency measured in several hours sure are useful, and can also be intercepted Method 2: Can be jammed by drone with laserpointer. Method 3: Let me just transfer gigabytes of data via physical signalling Method 4: Can still be jammed Method 5: Can in fact still be jammed?

Training models takes weeks, are you really worried about a couple hours?

> Can be jammed by drone with laserpointer

Ok, you're just joking

		If you’re receiving data optically from a space based laser, yes you are quite vulnerable to your detector being jammed by a much closer laser that doesn’t have to be nearly as powerful to add noise to the signal. Why do you think GPS is so easy to spoof? Actually I just googled (clauded?) to learn more about space lasers and found a paper describing interrupting quantum key distribution (tamper evident but not jam proof!) with a 1kw laser on the ground pointed at the satellite! So it really does not take many photons to fuck up an encrypted signal. “ Vulnerability of Satellite Quantum Key Distribution to Disruption from Ground-Based Lasers” https://pmc.ncbi.nlm.nih.gov/articles/PMC8659886/

Definitely not signals from low earth orbit.
