Title: STS-49 INTELSAT VI-R WETF exercise with astronauts Musgrave, Clifford, Voss 
 
Description: 
 
STS-49 Endeavour, Orbiter Vehicle (OV) 105, International 
Telecommunications Satellite Organization (INTELSAT) VI-R simulation at 
JSC's Weightless  Environment Training Facility (WETF) Bldg 29 was 
conducted with  extravehicular mobility unit (EMU) suited astronauts F. 
Story Musgrave,  Michael R. U. Clifford, and James S. Voss.  Astronauts 
practiced a three  person extravehicular activity (EVA) procedure for 
INTELSAT capture and  climbing into the airlock mockup.  No apparent 
problems were identified in  placing three astronauts in the airlock at one 
time.  Ground based exercises  were conducted after five failed INTELSAT 
capture attempts during the STS-49  mission.  Left to right are, Clifford, 
Musgrave, and Voss.  With Musgrave on  the remote manipulator system (RMS) 
manipulator foot restraint (MFR) and  Clifford on a portable foot restraint 
mounted on the payload bay sill  longeron, and Voss on a PFR mounted on a 
strut with the PFR Attachment  Device (PAD), the capture bar is maneuvered 
under the INTELSAT mockup.  In  this overall view of the test the three 
astronauts stabilize the INTELSAT  mockup by grabbing hold with their hands 
and then position the capture bar.   Test results provided input for 
orbiting STS-49 crewmembers on possible  alternate INTELSAT capture 
procedures.  Three OV-105 astronauts will attempt  to capture INTELSAT 
again on 05-13-92.  SCUBA-equipped divers assist in and  monitor the 
simulation activities.
