My understanding is Freedom command is in Reston, VA.  THe HST
is controlled by GFSC Greenbelt MD for Flight Dynamics and satellite
engineering.  The STScI Space Telescope Science Institute at JHU Baltimore
MD will receive all scientific data and schedule time for the HST.  
STScI does not have a TDRS downlink, they have a Hi-Speed line to
Goddard, that is unless Dr Jackson of STScI was mis-informed.
