# Orbital Launch Matrix

Orbital Launch Matrix is a public US/EU-aligned launch-intelligence catalog (plus allies such as JAXA and ROK). It lists launches from the last 18 months plus upcoming, with spacecraft bus, bus maker, spacecraft name, payload, operator, and contractor.

Scope:
- US/EU-aligned providers and pads only. China and Russia are excluded.
- Bus and payload names are copied from public sources only and are never invented.
- Bus = Not disclosed unless a PUBLIC source names the bus model for that mission. Prime/contractor alone does not auto-fill bus.
- Exception: publicly named SDA planes only (York S-CLASS, KeepTrack LM-T1TL, Rocket Lab Lightning for T2TL-Beta).
- Launch vehicle is a secondary field. It is not a bus, parts, or rad-hard claim.
- Contractor is the payload prime and bus maker, not the launch vehicle provider alone.
- MCU/part numbers from private CRM sources are not published.

Live files under /api/ refresh from Launch Library 2 merged with the snapshot. Files under /data/ are a static snapshot of the same join keys.

## Join keys

| Column | Meaning |
| --- | --- |
| bus | Spacecraft bus model. Unknown = Not disclosed. Never invent a model. |
| busMaker | Bus manufacturer. Empty when bus is Not disclosed. Preferred join with bus. |
| spacecraft | Spacecraft name. Fallback join key. |
| payload | Payload description from public sources only. |
| contractor | Payload prime and bus maker. Fallback join key. Not the launch vehicle provider alone. |
| operator | Launch service provider, with payload operator in parentheses when known. |
| mission | Mission name. |
| net | No-earlier-than launch time, UTC ISO-8601. |
| vehicle | Launch vehicle. Secondary field; not a bus or parts claim. |
| orbit | Destination orbit. |
| status | LAUNCHED, GO, NET, or TBD. |
| date | UTC calendar date of NET (YYYY-MM-DD). |

CSV header (RFC4180 quoted): date,mission,spacecraft,bus,busMaker,payload,operator,contractor,vehicle,orbit,status,net

Preferred join: busMaker and/or bus. If those are empty or "Not disclosed", also try contractor and spacecraft.

## Suggested Copilot prompt

Join the uploaded spreadsheet to https://launch-matrix.pages.dev/api/launches.csv (fallback: https://launch-matrix.pages.dev/data/launches.csv). Match rows on busMaker and/or bus. If those fields are empty or "Not disclosed", also try contractor and spacecraft. Keep unmatched spreadsheet rows. Do not infer or invent a bus model. Treat "Not disclosed" as unknown. Vehicle is secondary. This catalog is US/EU-aligned launches only.
