Impressive, but the linked article didn't uses a high gain antenna array like was used to communicate with deep space probes.

They specifically wanted something with a low barrier to entry. Take a look at the antenna they used. Pretty impressive imo.

If I read that right, they used a GEO satellite as a relay, which is nothing like a low-power device, and GP's point was the asymmetrical distance record. Similarly, Hyugens experiment used a simple patch antenna at Titan (that's why it's notable), and a high-gain antenna on Earth.

Guess I should have read further in.

That's not lora modulated. My example was.
