  Title: Safety divers prepare HST mockup in the Neutral Buoyancy Simulator at MSFC
  Description:
  Safety divers in the Neutral Buoyancy Simulator (NBS) at the Marshall Space
  Flight Center (MSFC) prepare a mockup of the Hubble Space Telescope (HST)
  for one of 32 separate training sessions conducted by four of the STS-61
  crew members in June.  The three-week process allowed mission trainers to
  refine the timelines for the five separate spacewalks scheduled to be
  conducted on the actual mission scheduled for December 1993.  The HST is
  separated into two pieces since the water tank depth cannot support the
  entire structure in one piece.  The full length payload bay mockup shows
  the Solar Array Carrier in the foreground and the various containers that
  will house replacement hardware that will be carried on the mission.
