Third European Service Module main engine installation

The main engine of ESA's third European Service Module, which will power NASA's Orion spacecraft in space during the Artemis III mission, being installed at Airbus Space in Bremen, Germany.

This particular engine is no stranger to flying in space: it is a repurposed Orbital Maneuvering System (OMS) engine that has already flown on nine Space Shuttle flights, bringing to space ESA astronauts Leopold Eyharts and Roberto Vittori on missions STS-123 and STS-134 respectively, as well as NASA Administrator Senator Bill Nelson on mission 61-C.

This summer, ESA's third European Service Module will leave the integration halls of Airbus Space and travel to NASA's Kennedy Space Center, to be connected to the crew module in preparation for the Artemis III launch to the Moon.
