Good Morning, Earth! A complex & vital day on Space Station, as Tom and Chris suit up and go outside to help fix the ammonia leak. Busy day!

This will be the first time that WVS views have been downlinked via the new Ku system. Hope it works as before - video via the SPDM for the recent RRM ops was apparently unusable at first, and needed some reconfig for the new system.

Ok folks, as Family Guy's Joe Swanson would say "Let's DO THIS!"

Pete's article is too good to mess around with, so what we'll do is use his as the baseline:
http://www.nasaspaceflight.com/2013/05/ammonia-leak-iss-contingency-spacewalks/

And I'll write a live article - which means I open with an abstract and a few paras and add paras as we go.

So I'll really need everyone's help with the screenshots and such in here.

Sir Rob of Navias covering. I suppose it was always going to be either him or Josh. Need the big guns for this one.

Consoles are packed for this.

Right, someone take over. Going to do the article.

Rob Navias says that if they can't find any obvious source of the leak after removing the PFCS, then they will simply re-install the PFCS (without replacing it) and "call it a day".

dsmillman · « **Reply #116 on:** 05/11/2013 11:17 am »

The R&R of the PFCS is available in the STS-115 EVA checklist.
It is in the contingency section starting at page FS16-51 on page 325. There is one difference between that one and today's EVA. In today's EVA the existing PFCS will be removed first.
