• Looks like he is using quite some force. It's almost there.

• They got the bolt out, but, the next challenge will be when they have to reinstall that brace... at the end

  I thought UCCAS and PAS was basically the same thing with different names. Glad you correct me.
  

  
  From the ISS Structures and Mechanisms Training Manual available on L2:
  
  

  Quote

  The PAS and UCCAS are
  identical except that the UCCAS contain a redundant Integrated Motor Controller Assembly
  (IMCA), for both the Capture Latch Assembly (CLA) and Umbilical Mating Assembly (UMA).

  
  The document further indicates that the lack of redundancy was a cost saving measure.
  
  STS-129 documents say that the lack of redundancy is why ELC-2 will be installed during EVA-2. If the IMCA on either the CLA or UMA fail, they can be actuated by the EVA crew. The ELC need to be connected to the truss within a few hours (6-8 I believe) of being unberthed from the payload bay.

• The platform is coming out from the truss. Next they will reinstall the troubling diagonal bracket.
  
  EVA elapsed time is up to 5 hours and 41 minutes.

• Thanks everyone for the continued coverage. 
  
  Added as I meant to ask, did they lose a bolt?
• #210 by arkaska on 19 Nov, 2009 19:14
• Now they will try to drive back the bolt they had trouble releasing earlier.
• #211 by arkaska on 19 Nov, 2009 19:19
• Sun is coming up.

  no they did not loose the bolt, it was stuck so it would not come out far enough to give clearance in the "stow clevis" when they were un-stowing the brace. Had to hit it with hammer as it is still "stuck" in the clevis.
• #215 by arkaska on 19 Nov, 2009 19:28
• I thought the PAO sad they where just making sure the bolts where tight? They haven't even finished putting the PAS in place!
