This required me to look around the web a little further then 
pull out my old ( 1960 ) PSSC highschool physics text and
the copy of Feynman's 1963 course which is so good it's still
in print .

 Kepler discovered that the period goes up as the 2%3 power of
 the radius of the orbit . Basically , the while the=
 gravitational
 pull is decreasing as the square of the radius , the distance=
 the
 moon has to fall ( that's what it's doing of course ) also goes
 up as r ^ 2 . so the speed , ( if my head is working right )
 has to increase as r . 

 The radial velocity slows down , but the distance traveled 
 goes up .

 Correct me please Travis . You're the engineer heer .
