The SatNOGS project has a database component with a nice API for querying sat information. It is an active project, so it is far from a one-stop machine-queryable resource. But that is a stated goal of the component.

https://db.satnogs.org (add "/api" to poke around what is query-able at the moment)

I'll be at the Symposium this weekend along with a few of the SatNOGS people flying in from Athens, Greece, who will do a talk. IIRC they will be bringing some of the hardware also. In-person would be a great time for lots of discussions.

As an open project, in practice things get done by someone doing it. Feature requests are nice, but a request accompanied by code is better. Everyone currently involved has a day job :) Let's work together!
