I am. outraged at the university's treatment of a retired professor.. Mark of Excellence The matter of the practical benefits of emeritus status, however, is amoot point at many institutions, especially community colleges, thatlack resources to share with retired faculty members.
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).
Mission STS-121, NASA's second return to flight test mission is soon to lift off from NASA's Kennedy Space Center in Florida. How is the launch time determined and how long will it take the Space Shuttle to reach the International Space Station? NASA Launch Director Mike Leinbach has been working closely with orbiter Discovery and her crew. Mike, thanks for taking time out of your busy day to share your insight about launching a space shuttle into space.
