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 the Shuttle's maximum speed of about 30,000 km/hr, it would take more than 16 years to reach Pluto.   The New Horizons spacecraft was launched by NASA in 2006 and reac â¦ hed a new record velocity for spacecraft, more than 58,000 km/hr.It was further accelerated by a gravity assist from Jupiter in 2007.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.
