We answered this question on the show...



If you have a high speed entry, you create a pocket of ionised gas around your probe.  The gas is heated up so much, it becomes ionised - itís stripped of its electrons.  That is not transparent to radio waves, so you have a radio black out. 
The same thing happens with vehicles re-entering the Earthís atmosphere.  It used to happen with the shuttle I think and the Apollo vehicles.  So thatís the main reason.  Itís the state of the gas around a high speed probe.
