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).
I'm asking because I was reading about the new planet, Gliese 581, which is said to have earth like habitation characteristics, but is 20.5 lightyears away-- impossible to reach in a human lifetime. So I would like to know how fast our space shuttles go...eport Abuse. Well, the space shuttle normally cruises along at 17,000 mph. At that speed, assuming a straight line shot to Gliese 581, it would take 810,502 years to get there. If we go back to the velocity of the Apollo missions to the moon (..about 45,000 mph..) we're down to a one-way trip of 305,706 years.
