The thing is that there has not been a news story about this project for a while and the Telegram group has disappeared if development stopped or what
Not at all Onix: we are working hard on the project every day. And the Telegram group is up and running. (In fact, it has more members than at any time in the past.)
You may not see many updates because the customers we are engaging are rather large. As a result, they have long lead times and often have NDAs (non-disclosure agreements) in the initial stages. But don't worry, we will update you when we can!
Lack of updates doesn't always mean something is wrong. You have to look at the strength of the team, what they are building and who they are working with. If you are hungry for details, this is a great read about the collaboration between Hadron, Aikon and STSCI:
