Space Launch Systems and Ground Support Systems

 

At the Kennedy Space Center, under the Engineering Services Contract, SGT actively supports a number of engineering, science, and technology development projects. Excellent examples of this support are the NASA Space Launch Systems and Ground Support Systems.

The following video depicts the NASA Space Launch System (SLS) vehicle rolling out from the Vehicle Assembly Building (VAB). The SLS is sitting on its Mobile Launcher (ML) that was built for the Constellation program and modified to accommodate the SLS vehicle. The ML and vehicle are being moved by the Crawler Transporter (CT). The CT was built for the Apollo program and is being upgraded and refurbished to accommodate the SLS vehicle. Once on the pad (Pad B at Kennedy Space Center (KSC), the video follows a typical launch sequence that includes the loading of the crew using the Crew Access Arm (CAA), retraction of the CAA prior to launch, and launch, including the disconnection and retraction of the umbilical arms (Orion Service Module Umbilical (OSMU), Interim Cryogenic Propulsion Stage Umbilical (ICPSU), Core Stage Inter Tank Umbilical (CSITU), Core Stage Forward Skirt Umbilical (CSFSU), Tail Service Mast Umbilical (TSMU), and the Vehicle Stabilizer (VS).

The following video illustrates the NASA Space Launch System (SLS) ground servicing and stabilization systems operations on the Mobile Launcher (ML). It depicts the detail and retraction sequence for each umbilical arm (Orion Service Module Umbilical (OSMU), Interim Cryogenic Propulsion Stage Umbilical (ICPSU), Core Stage Inter Tank Umbilical (CSITU), Core Stage Forward Skirt Umbilical (CSFSU), Tail Service Mast Umbilical (TSMU)), Crew Access Arm (CAA), and the Vehicle Stabilizer (VS).
