1. Assuming it's easy to keep 20C (I thought it's problematic to keep such a low temp for satellite which has problem radiating heat away), what about transfer, is electronics not yet operating back then or do you use some heating elements specifically for bootstrap?
2. Just to be clear 25C is what is used as room temp in electronics and not something you set your thermostat too at home, right?
3. (easily googlable feel free to skip) - how does heat management look for satelatie electronics? Are peltiers used? Do you just put everything in some heat conductive material? Is there some gas sealed around PCB or is it vacuum? In case of the latter and if everything is not surrounded by some heat conductive substance how do you deal with thermal runaway? Is maybe PCB itself and paths enough to make it less bad than I imagine?
Thanks a lot, I'm sorry about so many questions, just got curious.
