@AstroSamantha and I are doing a dry run in the NBL for tomorrow's planned Spacewalk, looking for the ammonia leak pic.twitter.com/0oVCCsKseb

Suddenly very busy! Ammonia leak on the outside of station means that Cassidy and I will be doing a spacewalk tomorrow to try and repair it

Oooh, I got a Tweet from Doug Wheelock! :)

@Astro_Wheels I'm sure your QD experience will come in very handy Wheels!

Douglas H. Wheelock ‏@Astro_Wheels:
@Space_Pete Discussing choreography this morning. These QD's often don't play nice, but confidence is high & the team is ready to execute.

That's awesome! :)

And I agree, this is where MOD and the ISS people show what it's all about. Leak observed to EVA within two days.

Notes from the ISS LIVE coverage since I haven't seen any... Status update at 1500 Houston time (2000 GMT) This is before the final IMMT so decision on the EVA will not be final.   The "BIG EVA" list in now 12--two have dropped off somehow.  Undock is still scheduled for Monday although I can't see how that's possible with prep for that at a standstill--at least on the USOS side.
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

New message on board covers stationing 4 PBAs (portable breathing apparatus?) in the airlock.  Assume that is for possible ammonia contamination.

FYI, I hear that CNN will be covering this live tomorrow morning.  Typically that means that occasionally they'll turn to the Florida reporter for an update, and will have continuous video on one of the streams at cnn.com/live .

PSA #1: EST does NOT mean "Eastern Time".  Use "Eastern" or "ET" instead, all year round, and avoid this common error.  Google "EST vs EDT".
PSA #2: It's and its: know the difference and quietly impress grammar pedants.  Google "angry flower its" .  *** See profile for two more NSF forum tips. ***

It was noted last year:

At the time, it sounded like the list wasn't quite so static; post from erioladastra:

How big are the pump module they're talking about replacing?  And is there any possibility of brining the failed unit or parts of it home so that they can be inspected for root cause?  It'd be a shame to not get that engineering knowledge.  That's half of what ISS is for.

Even if they could physically fit inside Dragon, they'd be contaminated with ammonia, so unable to be brought inside right?  Or could the old parts be allowed to outgas and dry out for a while in vacuum, to the point where it's safe?

What is the other disposal option?  Strap it into the Dragon trunk for deorbit?

While the crew preps for their EVA, could DEXTRE be over at the site observing or prepping the site for the Astros ??

MEDIA ADVISORY: M13-075

NASA SETS TV BRIEFING TODAY TO DISCUSS SPACE STATION STATUS

HOUSTON -- NASA managers will discuss the status of the International
Space Station, including the latest on an external cooling loop leak
that developed Thursday, during a televised briefing today at 3 p.m.
CDT (4 p.m. EDT).

The news briefing will take place at NASA's Johnson Space Center in
Houston. It will air live on NASA Television and the agency's
website.

Journalists may ask questions from participating NASA locations and
through a phone bridge by calling the Johnson newsroom at
281-483-5111 no later than 2:45 p.m.

Mission managers have spent the day reviewing data on the leak, which
is located on the station's far port truss, and whether to conduct a
spacewalk Saturday to investigate the leak. A final decision on the
possible spacewalk is expected later today.

The news briefing participants are:
- Michael Suffredini, International Space Station Program manager
- Norm Knight, NASA chief flight director

There's probably no urgency for disposal  -- if the Station program decides to go ahead with the remove and replace, the unit can be stored in the location of the spare chosen for replacement.

(There's some "diagramming" on L2.)

Evening DPC started.  Pavel with assist with EVA prep tomorrow.  MT translate will be started early tonight because SPDM (DEXTRE?) ops went so well today.

I was told Cassidy will use EMU 3010 and Marshburn 3005.

Thanks, was just about to ask that question!

Radiator is not the source of the leak.

Significant change yesterday with the loss of quantity.

Moved all the power loads and shut down the system. Fortunate that the crew onboard have been out to this area on a previous EVA.

EVA objective is to see where the leak is. Expect the area to be very small. Will look at the pump and QD with a changeout to recover the system. Depends on how much ammonia is left to restart. Another EVA would be required if they need to fill it up.
