Powering Exploration Mission-1

During a "Powering Exploration Mission-1" ceremony in the Neil Armstrong Operations and Checkout Building high bay at NASA's Kennedy Space Center on Nov. 16, 2018, Phillippe Deloo, left, European Service Module program manager at the European Space Agency (ESA); and Mark Kirasich, Orion Program manager at the agency's Johnson Space Center in Houston, answer questions. The event was held to mark a major milestone, the arrival of the European Service Module (ESM) for Orion's Exploration Mission-1. The service module, built by the European Space Agency, will supply the main propulsion system and power to the Orion spacecraft during EM-1, a mission to the Moon. The ESM also will house air and water for astronauts on future missions. EM-1 will be an uncrewed flight test that will provide a foundation for human deep space exploration to destinations beyond Earth orbit. EM-1 will be the first integrated test of NASA's Space Launch System, Orion and the ground systems at Kennedy.
