The first integrated piece of flight hardware for NASA's Space Launch System (SLS) rocket, the Interim Cryogenic Propulsion Stage (ICPS) was offloaded from the Mariner barge at Cape Canaveral Air Force Station in Florida, and transported to the United Launch Alliance (ULA) Horizontal Integration Facility where it will be removed from its flight case. The ICPS was shipped from the United Launch Alliance (ULA) facility in Decatur, Alabama. The ICPS is the in-space stage that is located toward the top of the rocket, between the Launch Vehicle Stage Adapter and the Orion Spacecraft Adapter. It will provide some of the in-space propulsion during Orion's first flight test atop the SLS on Exploration Mission 1.
