Solenoid valve for a Rocketdyne SE-6 thruster, as used in the Gemini Reentry Control System (RCS), measuring approximately 3.25″ x 2.25″ x1.25″, marked on the body: "P/N 409403, S/N 931980, 9/19/64." In fine condition.
Each Gemini capsule was equipped with sixteen SE-6 thrusters positioned in the nose for maneuvering and control of spacecraft attitude during reentry. They were famously utilized during Gemini 8 as the capsule began to spin dangerously out of control: staying calm under pressure, Neil Armstrong fired the RCS thrusters to regain stability.
