Fixed launch pads are specialized platforms used for launching rockets and spacecraft. These structures are permanently installed at spaceports and provide a stable base for vehicles during countdown and liftoff. They are equipped with various systems, such as fueling lines and electrical connections, to support the rocket's operations before launch. These launch pads are designed to withstand the intense forces and heat generated during a rocket's ascent. They often include safety features and support equipment, such as ground support equipment and flame deflectors, to protect both the vehicle and personnel. Examples of fixed launch pads can be found at facilities like NASA's Kennedy Space Center.
