Full-size Mariner Spacecraft propulsion module mockup displayed on a metal stand, measuring approximately 18"x 18" x 22", featuring metal ports, valves, brackets, tubing, and thrust chamber, and mock propellant tanks crafted from silver-painted laminated wood. Exhibits some scuffing to the tanks.
The Mariner spacecraft utilized a liquid monopropellant motor, with hydrazine fuel held in a rubber bladder inside the larger doorknob-shaped container called the pressure dome. Pressurized nitrogen was held in the smaller sphere. On the command to fire, the nitrogen was shot into the pressure dome and squeezed the rubber bladder, forcing the fuel into a combustion chamber.
