Every object.

Provenance, frame by frame
Every pixel carries its origin: telescope, filter, seeing, the engineer on shift.
/03

Fourteen instruments,
one sky.
Each survey watches its own slice of the spectrum. Meridian weaves them into a single, queryable record.
Selene-40.38 Gm
Lunar cartography
A nightly re-survey of the visible face — every new impact catalogued within hours.
Polaris Net100 km
Atmospheric optics
Sixty all-sky cameras across the auroral oval, separating the atmosphere from what lies behind it.

Inés Vidal — Survey Lead, Cerro Alto
