How did the Space Shuttle launch work?

There is a long process to getting the Space Shuttle ready to launch! If it lands Vandenburg Air Force Base in California then it will need to be flown across the United States to Kennedy Space Center in Florida. This is done on the Shuttle Carrier Aircraft (SCA). All 135 Space Shuttle Launches happened from Florida. There are two launch pads - 39a and 39b. First the space shuttle is taken to the Orbital Processing Facility (OPF) where maintenance takes place. When there's a Rollover to the Vehicle Assembly Building (VAB) which is the Orbiter is lifted up and bolted to the Solid Rocket Boosters (SRB) and External Tank. The Shuttle is on top of the Mobile Launch Platform (MLP) and is then moved by the Crawler Transporter (CT) to one of the two launch pads. The launch pad is made of the Fixed Service Structure (FSS) and Rotating Service Structure (RSS). Other parts of the launch pad include the Orbiter Access Arm (OAA), Gaseous Hydrogen and Oxygen Vent Arms, Tail Service Masts (TSM), Sound Suppression System, and the Flame Trench. The launch involved Lift Off, Roll Program, Max-Q, and Main Engine Cut Off (MECO).
