§03 / Why a moon
The only telemetry on this site is real telemetry.
Defence sites love telemetry: scrolling system IDs, blinking coordinates, numbers that mean nothing. We wanted the opposite. Deimos AI LLC is named for the moon Deimos, so the one live readout on every page is where that moon actually is, fetched from NASA/JPL Horizons and checked by anyone who wants to.
It is a small promise that stands for a larger one. If we put a number on this site, it has a source, a date and a status in the Record. Including the moon.
