PHASE 1 SPACE DATA UTILITY

Every object in orbit has an identity, an owner, and a State that answers for it.

Other catalogues tell you where an object is. The Orbital Asset Registry tells you who is accountable for it — a permanent OAR Asset ID, a reasoned launching-State attribution, and every treaty provision that attaches, cited to a provenance-tracked source text.

What a catalogue can't tell you

IDENTITY
One ID that never moves
NORAD numbers get reused and COSPAR designators break on rideshares. An OAR Asset ID is issued once and survives renaming, transfer of ownership, and re-registration.
●210,406 aliases resolved
ACCOUNTABILITY
Reasoned launching-State attribution
Four limbs — launch, procurement, territory, facility — each evaluated separately, tiered by evidential strength, and shown with the basis for the claim rather than a single guessed flag.
●Tier 1–4 disclosed on every claim
PROVENANCE
Law cited to a hashed source text
Every treaty provision links to the Space Law Corpus with the SHA-256 of the exact text relied on. Citations can be verified years later against the record as it stood.

Cumulative currently-catalogued objects by launch year. The last five launch years account for 25% of the catalogue — attribution has not kept pace, which is the gap OAR exists to close.
03 / WATCHLIST

Decay watch & operator distress

Objects whose orbit is decaying, whose operator has filed distress, or against which a UN Art. IV cessation notice is on record. Unique to OAR.
