   Hubble has what might be considered a docking adapter, fitted on the   
   lst servicing mission.  How Dragon would use it is part of the TBDs   
   Clampin says need to be filled in before NASA would be giving the   
   go-ahead.  And if the mission includes attaching external gyros to   
   Hubble, those would have to be developed.

   NASA would be paying for it, as they would for a de-orbit mission.

   No, but I bet he's paying for some of the early planning.
