Question four. Please Explain That If A Craft Is Orbiting The Earth, I.G. The Space Shuttle And Its Orbit Degrades, Is It Possible To Safely Re-input Without Compromising The Integrity Of The Craft?

Answer :

In a normal re-entry an access interface point is chosen about four,000 miles from the landing site. That point is at 400,000 toes and is considered to be on the pinnacle of the surroundings. Since the Shuttle can be orbiting at 200 nautical miles (a nautical mile NM is 6080 toes as compared to the miles we are used to which might be 5280 ft) its trajectory should be changed to reach on the entry interface factor at the perfect perspective of descent and of route be at the correct location. If the Shuttle is in an orbit at 2 hundred nautical miles this is equal to 1,216,000 toes.
