  Title: STS-31 pre-deploy check of the Hubble Space Telescope (HST) in OV-103's PLB
  The Hubble Space Telescope (HST) is suspended above Discovery's, Orbiter 
  Vehicle (OV) 103's, payload bay (PLB) some 332 nautical miles above Earth.  
  The Canadian-built remote manipulator system (RMS) arm (out of frame), 
  controlled from in-cabin by the STS-31 astronaut crewmembers, held the huge 
  telescope in low hover position during pre-deployment procedures, which 
  included extension of the solar array (SA) panels and high gain antennae 
  (HGA). In the foreground is the closed HST aperature door and the Support 
  System Module (SSM) forward shell with stowed SA (left) and HGA (center) 
  visible.  The orbital maneuvering system (OMS) pods appear behind the HST 
  with the entire scene backdropped against the cloud-covered surface of the
