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).
Space shuttles must travel at 11km/s so that they can escape the force of gravity. the force of gravity is approximately 9.81. If you don't travel at a greater speed than the â¦ force of gravity, the rocket will not launch.he International Space Station is in a low Earth orbit between 199 mi and 216 mi. To maintain this orbit, the space station has to travel at a speed of about 17,500 miles per â¦ hour.
