Title: STS-52 deployment of LAGEOS / IRIS spacecraft from OV-102's payload bay (PLB) 
 
Description: 
 
During STS-52 deployment activities, the Italian Research Interim Stage  
(IRIS), a spinning solid fuel rocket, lifts the Laser Geodynamic Satellite 
II  (LAGEOS II) out of its support cradle and above the thermal shield 
aboard  Columbia, Orbiter Vehicle (OV) 102.  The remote manipulator system 
(RMS) arm,  with Material Exposure in Low Earth Orbit (MELEO), is 
positioned above the  port side sill longeron.  On the mission-peculiar 
equipment support structure  (MPESS) carriers in the center foreground is 
the United States (U.S.)  Microgravity Payload 1 (USMP-1) with Space 
Acceleration Measurement System  (SAMS), MEPHISTO (its French 
abbreviation), Lambda Point Experiment (LPE)  cryostat assembly (identified 
by JPL insignia), and LPE vacuum maintenance  assembly. Other payload bay 
(PLB) experiments visible in this image include:  (on the starboard wall 
(left)) the Canadian Experiments 2 (CANEX-2) Space  Vision System (SVS) 
Canadian Target Assembly (CTA) (foreground) and the  Attitude Sensor 
Package (ASP); and (on the port wall (right)) the Tank  Pressure Control 
Experiment / Thermal Phenomena (TPCE/TP) get away special  (GAS) canister.
