Shown here is a set of propellant inlet lines for an RCS (re-entry control system) thruster used on the manned Gemini spacecraft. The museum received the injector as surplus from the Gemini II mission. This engine, which helped control the spacecraft's attitude (roll, pitch, and yaw) produced a thrust of 25 pounds and used hypergolic (self-igniting) propellants (monomethyl hydrazine and nitrogen tetroxide). The entire RCS system consisted of two independent groupings of eight thrusters each. The system met performance requirements on all manned Gemini flights (Gemini III--Gemini XII) from March 1965 through November 1966.

The McDonnell Aircraft Corporation, the primary contractor for the Gemini spacecraft, awarded a subcontract for the RCS system to the North American Aviation's Rocketdyne Division on February 24, 1962.

Donated by the McDonnell Douglas Corporation.
