Haven't seen Blockstream Before, I thought no one did it before.
Perhaps my project is very similar, i will look what they are doing later.
The Idea of having Stellar nodes in Space is because this is the Stellar Blockchain.
If there is a network with the right name is this one.
I guess the 'honest' justification is that i need to start one of the robots next year, and sending a cubesat as a payload in a commercial rocket is the fastest/easiest way to reach space currently.
But i can't send it without a mission, and i thought that an Stellar core orbiting Earth will be very cool. 'Stellar in Space', like the whole package...
Once is launched there will no problem to communicate with the satellite, even an amateur radio club could help.
I am not an engineer, and I am more focused on the Concept.
But here is more info on the S band, used by Satellites: https://en.wikipedia.org/wiki/S_band
