NASA provided some new information about the first flight test for its Space Launch System (SLS) with the Orion spacecraft, called Exploration Mission-1 (EM-1). The agency did it in the occasion of the arrival to the Space Power Facility (SPF) in Sandusky, Ohio, of the test version of the Orion’s service module built by ESA known as European Service Module (ESM). This will allow NASA to begin testing the new spacecraft in its full configuration, a crucial step in the preparation of the EM-1 mission.
