LIVE: STS-122 Flight Day 5 - EVA 1

• They show the graphics for situational context for the viewer, also they are used when the Ku is not stable enough to get live video.

• I love the live feed much better myself, but sometimes Ku antenna coverage doesn't allow for live downlinks.

  Zephon907 - 11/2/2008 5:32 PM Why do you suppose NASA TV has gone from the live feed to the animated graphics and still pictures? The live feed is much more interesting.

  No Ku coverage. If they had video, they'd show it, not some simulation. Sometimes there's S-band coverage (when they show the sequential stills), but Ku is greatly restricted since the orbiter's antenna is not operational.

• Remember, this is a live update thread for the EVA.
  
  We've got threads for NASA TV questions. Shuttle Q&A and an ISS Q&A to help with any questions you may have.

• They cant feed off ISS Ku? I would imagine the Ku recivers on ISS are much better then the one antena the shuttle operates with

• Has anyone seen if Stan and Rex did indeed bring out their digital cameras in their tool bags?

  There's structural interferences and other factors apart from the quality of the recievers. This has been discussed before, both in live threads and the Q&As. As Chris said, this is live updates, let's not get into a long conversation about this here.

• NOW we have Ku, and we can see the adjustments they're making on the PDGF bolts.

  Since I'm new here, I'm not up on all the terminology, so I have to ask, what is Ku?  If I would guess, I would say it's the Live feed antenna, which cannot be received because of their position in orbit?

  Sorry.

• so, is Stan showing any signs of not having trained enough for the job (questions) or is he doing fine?

  Yes, Ku stands for the name of the spectrum band the signal is transmitted in. It's relayed directly to ground stations or to TDRS (satellites) and then to the ground. But sometimes the satellite isn't available for use by the Station, or directly not available. Same with the ground stations. Again, there's Q&A threads.

  Slightly ahead of schedule now, hard at work with the bolts.

• "Wonderful job on the PDGF installation" - Mission Control to Stan and Rex.  Sounds like they're done.
  
  Edit: Glove inspections now.  Right glove fine, for Rex.  Left glove, little bit of RTV missing, no vectran damage.  2 1/2 hrs into the EVA, right on timeline.
  
  Will be off to work now, unable to follow except through here.
• #134 by eeergo on 11 Feb, 2008 15:53
• A bit of RTV has flaked off Rex's left glove, nothing to worry about.
• #135 by eeergo on 11 Feb, 2008 15:54
• They're done with the mechanical installation, I think they have to connect the data and power cables next, after unscrewing the lower MMOD shield.

• looks like columbus is on its way to final home on orbit! it looks like there slightly ahead of shedule up there to

• Love looking at his gloves now...

  "Pristine, no damage"

• #138 by Lawntonlookirs on 11 Feb, 2008 15:57
• Is that what they are doing.  I thought they were counting with their fingers to make sure they had all of the bolts in.  JUST KIDDING.
• #139 by eeergo on 11 Feb, 2008 15:59
• On the lower shield now.
