# Photon

**Photon** is [[entity-org-rocket-lab|Rocket Lab]]'s in-house satellite bus / spacecraft platform — its **first in-house satellite**, which the company (per [[concept-show-dont-tell]]) announced only *after* it was already successfully operating in orbit, exemplifying the 'hardware-first' credibility strategy. Photon later served as the spacecraft bus for the [[entity-product-escapade|EscaPADE]] Mars mission, illustrating Rocket Lab's move up the value chain into complete spacecraft ([[concept-aerospace-vertical-integration]]).

*Provenance note:* Photon is cross-referenced in the source's relational links and discussed substantively in the text (first in-house satellite) and enrichment (Photon bus for EscaPADE); this entity note is included to resolve those references and preserve that substance.
