Title: Closeups of IECM grappled by RMS and positioned above payload bay (PLB)

Description:

Closeup view of the Marshall Space Flight Center (MSFC)-developed Induced 
Environment Contamination Monitor (IECM), a multi-instrument box designed
to  check for contaminants in and around the Space Shuttle orbiter payload
bay  (PLB) which might adversely affect delicate experiments onboard.  The
crew  maneuvered the Canadian-built robot arm, called the remote
manipulator system  (RMS), very near their overhead flight deck windows and
captured this scene  with a 35mm camera.  Cameras for the 11 instruments
are the black circles.  The access door to the arm and safe plug is located
about halfway up the  side of the box.  A cascade injector device appears
next to access door.   The rectangular opening at center of the box is the
optical effects module.   Mass spectrometer is in one corner with air
sampler bottles at the opposite  corner.  The colorful rectangle is the
passive array.  Not easily seen but  also a part of the instrument, are
Cryogenic Quartz Crystal Microbalance  (CQCM) and the temperature
controlled quartz microbalance.
