  Title: STS-31 MS McCandless and MS Sullivan during JSC WETF underwater simulation
  Description:
  This overall view shows STS-31 Mission Specialist (MS) Bruce McCandless II 
  (left) and MS Kathryn D. Sullivan making a practice space walk in JSC's 
  Weightless Environment Training Facility (WETF) Bldg 29 pool.  McCandless 
  works with a mockup of the remote manipulator system (RMS) end effector
  which  is attached to a grapple fixture on the Hubble Space Telescope (HST)
  mockup.   Sullivan manipulates HST hardware on the Support System Module
  (SSM) forward  shell.  SCUBA-equipped divers monitor the extravehicular
  mobility unit (EMU)  suited crewmembers during this simulated
  extravehicular activity (EVA). No  EVA is planned for the Hubble Space
  Telescope (HST) deployment, but the duo  has trained for contingencies
  which might arise during the STS-31 mission  aboard Discovery, Orbiter
  Vehicle (OV) 103.  Photo taken by NASA JSC  photographer Sheri Dunnette.
