open-data research

Tools that look closely at things almost nobody looks at. Everything is built on open data — satellite imagery, orbital elements, public channels. No closed sources, and no guesses passed off as facts.

Honest about the limits

What these tools do NOT do

The satellite cannot see who threw the switch. It sees that the lights went out — and darkness looks the same whether it came from a strike, a scheduled outage or cloud cover. Black Marble data arrives with an 8–12-day lag, so the Map of Darkness is retrospective: it is about what has already happened, not about right now.

A satellite visibility window is geometry, not a link. It means a spacecraft is above the horizon as seen from a given point. Whether the payload is switched on, where the gateways are, what the capacity is and whom the beams are allocated to — all of that is unknown, and none of it is claimed here.
