Rocket Lab - Photon

Rocket Lab Photon is the spacecraft platform product line of Rocket Lab USA, Inc., providing customisable, turn-key spacecraft buses for a range of commercial, government, and deep space mission applications. The Photon spacecraft was originally developed as an upper stage for Rocket Lab's Electron launch vehicle and evolved into a versatile standalone spacecraft bus deployed on lunar, heliocentric, and LEO missions. Notable Photon missions include NASA's CAPSTONE lunar Gateway pathfinder mission and the ESCAPADE Mars mission, demonstrating Photon's interplanetary capability. Photon buses provide integrated propulsion, power, avionics, communications, and attitude control in a standardised but configurable package, offering customers a complete spacecraft solution alongside Electron and Neutron launch services.
