Seeming to hang in midair, the Core Stage Inter-tank Umbilical (CSITU) is lifted by crane and rigging up to about the 140-foot level of the mobile launcher (ML) tower at NASA's Kennedy Space Center in Florida. The CSITU will be moved into place for a fit check of the attachment hardware. The umbilical will be lowered down and installed permanently on the ML at a later date. The CSITU is a swing-arm umbilical that will connect to the Space Launch System core stage inter-tank. It will provide conditioned air, pressurized gases and power and data connection to the core stage. Credit: NASA/Glenn Benson #NASA #NASAKennedy #GSDO #EM1 #exploration #rocket #mobilelauncher #SLS
