A long-exposure view of the mobile launcher at NASA's Kennedy Space Center in Florida.

NASA equipped the tower on the Mobile Launcher with several connections, called launch umbilicals, that will connect to the SLS core stage and twin solid rocket boosters, the interim cryogenic propulsion stage and the Orion spacecraft. They will provide power, communications, coolant and fuel.
