Title: Engineer Calvin H. Seaman demonstrates STS-49 INTELSAT capture bar at JSC 
 
Description: 
 
Project Engineer Calvin H. Seaman (center) briefs news media 
representatives  on the grapple fixture (capture bar) expected to be 
instrumental in the  capture of the International Telecommunications 
Satellite Organization  (INTELSAT) VI satellite in JSC's Mockup and 
Integration Laboratory (MAIL)  Bldg 9.  Seaman is a JSC engineer who 
designed the capture bar.  After  Endeavour, Orbiter Vehicle (OV) 105, is 
maneuvered into a tight proximity  operations configuration with the errant 
satellite, two STS-49 crewmembers  will attach the grapple device to the 
aft side of INTELSAT, as demonstrated  with this full-scale mockup.  The 
communications satellite will then be mated  with a perigee stage, which 
the crewmembers will carry with them on their May  launch, and released 
into space. Its motor will be fired many hours  afterward, sending it on 
its way to a higher, geosynchronous orbit. The  Errant Satellite Simulator 
is set up on the Air Bearing Floor for the  demonstration.  Photo taken by
