-        An interesting idea.  Modern comsats have several kilowatts of power,
-enough to run an ion or arcjet engine.  An electric engine running off a few
-kilowatts has a mass of only a few kg, so could easily be carried on the
-vehicle.  
-...
-A major problem would probably be radiation damage due to having to spend
-some months in the Van Allen belts as the satellite spirals down to LEO.

Question: what is the radiation profile of the Van Allen belts? This is
of interest because GEO is in the outer portions of the outer belt.
In particular, what is the ratio between the peak radiation level in
the belts and the level at GEO?
