EME, LORA and Meteor Scatter
Yep, first read of the story didn't say anything spectacular. In the HAM world, we have done this for quite a while with some cheap gear.
I don't see a mention on the Frequency used by Lora and considering the modules are available in 433Mhz, 868Mhz and 915Mhz, it may make a difference. Certainly 433Mhz would be quickest to get working with a borrowed ham yagi and suitable amp.
Might be harder with 915Mhz but i've not read up on the propagation properties of this frequency at distance. Normally higher frequency = less penetration.
What I find more of an achievement is the use of Meteor Scatter for communications. Bouncing your radio signal off of the ionised trail of a meteor passing through the upper atmosphere when that trail may only last from a few seconds to 30 seconds.
