Great project!

The overview doesn't really say what the satellite is for, so I went digging. It looks like you have two payloads, the https://www.qb50.eu/ system for analysing the thin plasma of the upper atmosphere and a 5MP imager (essentially a cellphone camera in space)?

How do you handle comms to ground - do you have to rent time on ground stations or do you have your own?

I quite like the use of multiple STM32F4 microcontrollers, one per subsystem. Are they special spacegrade ones or "regular"?

That's right we have two payloads a QB50 subsystem to analyse thin plasma and an imager

Comms are handled via the SatNOGS project open satellite project

STM32F4 aren't special spacegrade but they have already being used successfully in other cubesats
