Observatory Status & Data Integrity

Astrophyzix Planetary Defence reports are written using a fully dynamic, on-demand data retrieval pipeline linked directly to NASA's CNEOS NeoWs API infrastructure.

The monitoring interval is calculated at runtime and spans seven days forward from the exact timestamp of system access.

No caching layers, pre-processing, or static datasets are used. Every value presented is sourced from the most recent orbital solutions available within NASA systems at the time of query execution by the Astrophyzix Planetary Defence System.

Certain data is computed through the Astrophyzix Risk Index and presented alongside the raw data to give readers an easy to visualise scale of how notable an object is an a clear interpretation of the data.
