Curie is a liquid-propellant rocket engine designed and manufactured by Rocket Lab. A bipropellant is used for the propulsion of the third stage/kick stage of the Electron rocket, as well as the Photon.[2] The composition of the propellant is a trade secret.
The kick stage rocket produces 120 newtons (27 lbf) of thrust, and has a specific impulse of approximately 320 seconds.[3]
It was first used on 21 January 2018 during Rocket Lab's first successful orbital rocket launch, and helped to boost two small CubeSats, the weather and ship-tracking Lemur-2 CubeSats built by the company Spire Global, into a circular orbit.
