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).
At a rate of 17,500 mph, the speed required for a space craft to remain in orbit, it would take 12.74 seconds to travel the 62.1 mile distance from sea level to the closest ed â¦ ge of outer space.he space shuttle gets up to a speed of about 4 miles per second maximum which â¦ is enough to then coast in earth orbit for many days but not enough to get more than a few hundred miles up.
