Hi HN, I built this because I wanted to know what actually photographed my street.
Type anywhere and it finds every satellite that has passed over it in the last 7 days (SGP4 in the CelesTrak catalog, runs in your browser in about half a second), then pulls the actual Sentinel-2 / Landsat / NASA images from those passes.
Some funny bits:
- The transition search cannot skip a transition. Tested it against brute force on rods, anti-radian and tiny strips: 0 misses.
- All approximately 17,000 objects in orbit are drawn on the GPU, solving the Kepler equation in each frame.
- Sentinel-2 timestamps are often 5-10 minutes away from when the Sabbath actually crosses your location, which was fun to figure out.
It only says "view" if a real image exists, and it doesn't store your location.

I would appreciate feedback, especially on what data sources to add.
