Service Module
Orion’s European Service Module is the powerhouse that fuels and propels the Orion spacecraft in space. Located below the crew module, it provides critical functions including propulsion, thermal control, and electrical power generated by solar arrays. The service module will also provide life support systems including water, oxygen, and nitrogen for the crew. In addition to its function as the main propulsion system for Orion, it is responsible for orbital maneuvering and position control.
