Identity established
The current SATCAT record identifies ISS (ZARYA) as a payload in LEO.

Orbital Risk ReviewISS (ZARYA)
A demonstration of the evidence and analyst workflow for NORAD 25544. The subject was selected because the application's currently ingested public TLE group can support a complete provenance and freshness example.

analyst findings
A bounded interpretation of the available record.
The public catalog provides a stable NORAD identity and classifies the object in LEO.
The ingested stations feed contains a TLE with epoch May 1, 2026, 7:30 PM UTC; freshness must be evaluated at the time of use.
The application can compute an approximate current subpoint from the available TLE for orientation only.
The available evidence cannot establish conjunction risk because this MVP does not perform screening or use covariance data.
follow-up checklist
What an operator should verify next.
- 1Confirm identity and current state in the operator's approved systems.
- 2Review current CDMs and tracking-provider outputs for actual conjunction concerns.
- 3Compare source epochs and investigate stale or conflicting observations.
- 4Escalate maneuver questions to authorized flight-dynamics and operations personnel.
Method and limitations
Space Janitor ingests CelesTrak SATCAT metadata and the public stations TLE group, persists refresh and snapshot records, classifies broad orbit bands from catalog fields, and can run an approximate satellite.js propagation preview where two TLE lines exist. TLEs are mean orbital elements with known limitations. This sample uses no independent observations, covariance, conjunction messages, screening volume, or validated collision model.
