Photon is a satellite bus based on Rocket Lab's Electron kick stage.[1] It moves satellites into their appropriate orbits once boosted by rockets such as Electron. It is customizable for uses including LEO payload hosting,[2] lunar flybys, and interplanetary missions.[3]

Location of Photon on the Electron rocket

Photon uses chemical propulsion for orbit adjustments. It can use a variety of engines, such as the Curie and HyperCurie engines, as well as engines from third-party sources, such as the one powering the EscaPADE mission.[4]

Photon first launched in August 2020 on Rocket Lab's I Can't Believe It's Not Optical mission, where it served as a pathfinder. It has since flown three times. It flew the CAPSTONE mission.[citation needed]

Photon communicates on the S-band.[5] Depending on the orbital inclination (37° to Sun-synchronous orbit), it is expected to have a payload capacity of 170 kg (370 lb).[6][7] The interplanetary version was to have a 40 kg (88 lb) payload capacity.[8]

HyperCurie is an evolution of the Curie engine, which comes in monopropellant and bipropellant versions, while the HyperCurie is hypergolic[9] and electrically pumped.[10]
