Workers lower Atlantis Rudder Speed Brake panel onto a stand after removing the panel from the vertical tail.

In the Orbiter Processing Facility, workers lower Atlantis’ Rudder Speed Brake panel onto a stand after removing the panel from the vertical tail. The Rudder Speed Brake is being removed for inspection and maintenance prior to Return to Flight. The vertical tail consists of a structural fin surface made of aluminum, the Rudder Speed Brake surface, a tip and a lower trailing edge. The rudder splits into two halves to serve as a speed brake. The vertical tail and Rudder Speed Brake are covered with a reusable thermal protection system. The Rudder Speed Brake is used to guide and slow the Shuttle as it comes in for a landing.
