For what it's worth, NASA.gov in their own reporting of the EVA mentions that they "installed a TV camera."
It is mistake, of course...
Haha... well... there you go. Thanks PAO.

Sounds like we may need yet another US Station EVA before 118 arrives.
There will be a station US EVA in July before STS-118 arrives to jettison the early ammonia servicer tank (EAS) off of the P6 truss, it is no longer needed, that EVA is scheduled for around July 20, see this link for a tentative schedule:

They are really strugling with that shield!
Which would put plans into place as noted on the first page in an answer to JMS.

The tetheres were a temp measure, as seen in the plans for EVA-4, they are going to attempt to install the shield's bolts today. If that doesn't work then they'll have to go with the tethers, but as to why it's been problematic...I don't think the reasons have yet been noted.

Maybe 5 - 10 minutes to KU on TDRS-West, just a guess on my part due to the complex's orbital position. (okay, as soon as I post, KU returns!)

Approaching orbital noon on this pass within five minutes, 30 minutes of comm & KU through TDRS-West available.

As far as the reasons for the difficulty, there was a little blurb in last night's press conference about it. Apparently J.R. was overheard speculating that the shield was simply not made correctly.
That's a bit of hearsay, though.

Pat will do the vent open.
They want to get them in asap.

Moving onto the H2 Vent Valve Open Ops. for this EVA, the vent valve is open!, the MMOD shield has been tethered down for now. Now on orbit 143 of the STS-117 mission, sunset is 30 minutes away.

19 minutes left of West KU comm coverage before handover to East, ZOE is 54 minutes away, this pass it will be a 8 minute ZOE.

Dzus fasteners will not engage unless aligned perfectly. There is no leeway. So it's surprising that such a fastener was used on the shields. Bolts would have been better IMHO.
As both shields were removed from their original positions, they SHOULD have gone back OK. But I guess zero G environment makes it a little harder to do.

EVA 4 is coming to an end, tool inventory underway, before ingress in the airlock, they should be in the airlock before we get to the ZOE area.

Look for a replacement MMOD shield to go up on the next shuttle flight with revised fasteners.
