Dear publish1000-ga; You posed a great question. The answer is really much simpler than it first appears. The US Space Shuttle uses a rocket propulsion system to get into its final orbit in its approach to Earth. Other than that the Shuttle is essentially falling and during re-entry the aircraft is actually a glider. The reentry speed is largely dictated by the Earth gravitational pull and given the physics of such a reentry the speed is typically approximately 25,405 feet per second (17,322 statute miles per hour).
