Rocket Lab Curie
Rocket Lab Curie is an in-house, restartable liquid-bipropellant engine for Electron’s Kick Stage. Rocket Lab’s payload guide specifies 120 N (0.12 kN) thrust and multi-burn orbit-raising, circularization, and disposal operations; the canonical graph preserves one Curie engine on the Electron Kick Stage while leaving propellant chemistry unspecified.

- Note
- Rocket Lab’s payload guide specifies Curie as the Kick Stage engine, lists liquid bipropellant, six reaction-control thrusters on two pods, and 120 N thrust for the stage; the Curie main-engine role is recorded without inferring propellant chemistry.
