Earth sent some colonist to a earth-like planet, interstellar distance away, a long time ago. This colony is very sustainable and growing. No need to worry about that. The problem is: Due to Kessler syndrome, no satellites can be put into orbit anymore without being hit. The satellites designed for communicating to the base is destroyed. Earth sent a warning message saying: Kessler Syndrome No communication! All the colony got was, Kessler Syn. They never got the rest because the satellite was destroyed. The colony can still communicate with Earth, but Earth can't talk back.You can handwave communication latency. But if- Interstellar communication, read this (no ships though).
My main question is:
How would the colony react? What would they do now being isolated one way?
They are completely sustainable, so no need to worry about that.
