• We now have S-band video stills, expect a good KU coverage pass through TDRS-West coming up in about ten minutes or so as the complex moves north and east of New Zealand towards TDRS-West. Sunrise is now occurring, Rex is continuing to remove the four bolts holding the NTA inside P1. Spacewalk PET 2:45.

• Rex is now holding on to the old NTA that was just removed the P1 truss as seen in Felix's screen shot above. Should have a good KU pass for the next 25 minutes or so, 38 minutes to sunset, Atlantis 10 minutes away from starting orbit 95 of the STS-122 mission. Both NTAs (old & new) are attached to the CETA cart temporarily.

  Interesting that neither Harmony or Columbus (nor Kibo) seem to require those Space Vision System Dots that cover the station from Destiny to Zarya.

  
  because it didn't work

  
  Jim is right for sure, but can anybody update Wikipedia?

• The new NTA has been removed from the CETA cart by Rex and it is moving towards its location inside the P1 Truss with the assistance of Rex, Hans, and Leland operating the SSRMS inside the ISS.

   Jim is right for sure, but can anybody update Wikipedia?  http://en.wikipedia.org/wiki/Advanced_Space_Vision_System

  One of the core policies of Wikipedia is verifiability, and that comes from reliable sources (not forums, not personal websites, blogs, or other non reliable sources, etc.)  

  According to this NRC report, the Space Vision System was highly successful:

  http://www.nrc-cnrc.gc.ca/eng/education/innovations/discoveries/svs.html

  "The resulting Advanced Space Vision System (ASVS) was even better than the original. MacLean finally tested it in 1992 aboard Space Shuttle Columbia.   In 1995, it was used to attach the Orbiter Docking Station to the shuttle and dock with the Mir Space Station. Since 1999, the ASVS has been critical in constructing the Canadarm II and the Mobile Servicing Station on the International Space Station.

  After the Space Shuttle Columbia was lost in 2003, this safety scanning system became a major priority to prevent the loss of future shuttles and crew.   The detailed scanning technology can detect faults in the shuttle's protective tiles down to a millimetre."
  

  Without sources that can verify that it "failed", that cannot be added to the article, as it would be considered original research not supported by reliable sources. Keep in mind that Wikipedia is an encyclopedia, that offers information, not personal opinion. If anyone has some URLs that explain why the system isn't used on Harmony or Columbus, then those could certainly be added to the article, something I'd be happy to do.

• The complex will pass south of Mexico City in 5 minutes and across northern Florida & Georgia in about 10 - 15 minutes, 28 minutes to sunset, the new NTA is now soft docked and inside the P1 truss, it is now ready to be bolted in place and the electrical and fluid connections to be made.

• The new NTA is being bolted into place as seen in Felix's screen shot above! 10 minutes to TDRS-East handover, 25 minutes to sunset,
  great views from the cameras on the SSRMS (colour) and Rex's helmet cam.
