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).
The International Space Station travels in orbit around Earth at a speed of roughly 17,150 miles per hour (that's about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes! You can see the ISS' location and speed at this link which also has a real-time video feed from cameras attached to the outside of the station. 1  Javascript must be enabled to use Cool Cosmos. 2  Learn how.
