The Mariner barge arrives at Cape Canaveral Air Force Station in Florida, carrying the first integrated piece of flight hardware for NASA's Space Launch System (SLS) rocket, the Interim Cryogenic Propulsion Stage (ICPS). The ICPS was shipped from the United Launch Alliance (ULA) facility in Decatur, Alabama. The ICPS will be offloaded and transported to the ULA Horizontal Integration Facility where it will be removed from its flight case. 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.
