Title: STS-49 INTELSAT VI-R WETF exercise with astronauts Musgrave and Clifford 
 
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 and  Michael R. U. Clifford.  Ground based exercises were 
conducted after five  failed INTELSAT capture attempts during the STS-49 
mission.  Musgrave (right)  on portable foot restraint (PFR) mounted on the 
INTELSAT cradle and Clifford  on a portable foot restraint (PFR) mounted on 
the payload bay (PLB) sill  longeron get handholds on the INTELSAT mockup 
as the capture bar freefloats  in the PLB (foreground).  Once the 
astronauts stabilize the INTELSAT mockup,  they will attach the capture 
bar.  Test results provided input for orbiting  STS-49 crewmembers on 
possible alternate INTELSAT capture procedures.   SCUBA-equipped divers 
assist in and monitor the simulation activity.
