Orion Propulsion model tanks

ESA’s contribution to NASA’s Orion spacecraft is the European Service Module, designed to provide the spacecraft’s propulsion, electrical power, water and thermal control. The model, designed by Airbus Defence and Space, was assembled by OHB Sweden.

Made from steel and containing propellant and helium tanks, among various electronics and command systems, the Propulsion Qualification Model allows engineers to determine how well systems are working together.
