The FSS on Pad 39A was constructed from most of the top of the umbilical tower of Mobile Launcher 2, while the FSS that was on 39B was constructed from most of the top of the umbilical tower of Mobile Launcher 3 (Mobile Launcher 3 would later become Mobile Launcher Platform 1 for the Shuttle).

mission, SpaceX uses the term White Room to refer to the end of the Crew Access Arm at LC-39A. On the first launch attempt, NASA and SpaceX began a tradition to sign the NASA meatball logo (for NASA launches) or the SpaceX logo (for private launches) at the end of the Crew Access Arm.

which allows maintenance and crew access. Immediately before ignition of the rocket's motors, all connections between the tower and the craft are severed, and the bridges over which these connections pass often quickly swing away to prevent damage to the structure or vehicle.

NASA used this room for astronaut final preparations before entering the spacecraft such as donning parachute packs, putting on helmets and detaching portable air conditioning units. After 2014, NASA planned to move the White Room to a museum. As of the
