Nice work on the sim, that's really cool! Love the synced video as well.
This is such a fun space to fiddle around in as an amateur. I've been experimenting with using actor systems for automating Kerbal Space Program with the KRPC extension; first projject can get a Vostok-like ship into orbit [0]. I thought I knew quite a bit about rocket guidance & control until I started writing these wee projects! And that's even using the simple "auto-pilot" built into KRPC to keep the rocket pointing in roughly the direction I tell it. I've been very slowly starting out on a new system which uses parallel WASM runtimes, so you can program rocket control in any WASM-targetting language. Starship/Falcon style landings are definitely one of my goals.
