Title: STS-49 ASEM activities illustrated with PLAID computer graphics 
 
Description: 
 
STS-49 Endeavour, Orbiter Vehicle (OV) 105, Assembly of Station by 
Extravehicular Activity (EVA) Methods (ASEM) activities are illustrated 
with PLAID computer graphics.  An extravehicular mobility unit (EMU) suited  
crewmember, positioned on the remote manipulator system (RMS) manipulator  
foot restraint (MFR), grabs and maneuvers the multipurpose experiment 
support  structure (MPESS) above OV-105's payload bay (PLB) using the 
steering wheel  assembly.  Once in position the MPESS will be attached to 
the truss assembly.  The crewmember lifting the MPESS out of the PLB is 
evaluating mass  manipulation and berthing of a relatively large mass.  
This will simulate  techniques to be used for module-to-truss installation 
for Space Station  Freedom (SSF).  A second EMU suited crewmember oversees 
and directs the MPESS  manipulation from a portable foot restraint (PFR) 
attached to the starboard  sill longeron.
