I load Celeste track orbital parameter data and continuously propagate objects forward in time using SGP-4, so you see predicted positions evolving every minute. I then run a collision cascade simulation, including fragmentation direction and secondary collision counts within a 90 minute screening horizon, and I show results for the orbit I selected as fine. I used a Gemini 2.5 Flash based copilot to translate natural language goals into deterministic simulation actions. No action was explicitly requested from viewers.
