The Node 2 hatch has been closed

Targeteer · « **Reply #2 on:** 05/18/2014 07:40 am »

vestibule being de-pressed

First pressure-check failed. pressure rising slowly.

Swanny tried to partially open and re-close an MPEV (didn't get which one, I think it was node 2 related, maybe the node 2 hatch MPEV).

Now re-evacuating the vestibule, and restarting pressure checks.

InfraNut2 · « **Reply #4 on:** 05/18/2014 08:16 am »

Swanny reporting pressure readings of 1.2 at 2 min and 1.9 min at 3 min. Houston likes them.

While writing this: 3.0 at 5 min. Houston: "Fantastic, sounds like we made it"

InfraNut2 · « **Reply #5 on:** 05/18/2014 08:21 am »

Depress complete. (I.e. the procedure, including some pressure checks)

InfraNut2 · « **Reply #6 on:** 05/18/2014 10:09 am »

CCP function test complete.

edit: CCP = Crew Command Panel (for Dragon commanding--connected to CUCU; there is a similar separate command panel "HCP" for HTV/Cygnus connected to PROX. There is similar functionality for ATV but that system is more different I think)

Do we know what is the planned time of unberthing? (I'm not talking about the release-from-SSRMS time of 13:26 UTC)

Chris Bergin · « **Reply #8 on:** 05/18/2014 11:20 am »

They should be unberthed already? Release one hour away.

Or not, see below!

InfraNut2 · « **Reply #9 on:** 05/18/2014 11:26 am »

Dragon grappled. Breaks on.

Screencaps taken just before and just after.

(Have had problems following the recent conversation on the ISS feed. The comm seems noisy/distorted and Swanny's gruff and nasal voice does not carry well through the noise/distortion. Also they often refer just to procedure steps by number. I tried and failed to locate the procedures on L2 -- my search-fu is not at its best today).

However, the procedures - by the numbers they will be enunciating - will be another document that I'm sure someone will PM or post to you. I tend to only remember the L2 documents with the pretty pictures!

InfraNut2 · « **Reply #12 on:** 05/18/2014 11:43 am »

I have not seen or heard any unberth time. Neither the coverage announcement or the NASA TV ISS coverage friday mentioned it -- only the release time was mentioned.

The arm was moved into position friday, but they must have stopped at the pre-grapple position, unless I misundersood the comm just now.

There was a also a CCP check friday, so the (very quick) one today must have been a quick double-check.

edit: added screencaps from the 2 mentioned preparation activities on friday.

CBM unbolting in work.

De-mate complete.

Chris Bergin · « **Reply #15 on:** 05/18/2014 12:00 pm »

NASA TV coverage:

Calling it SpaceX Dragon-4 now......fourth ISS Dragon, but it's really CRS-3/SpX-3.

Aiii. Already moving the Dragon to the Demate position (~1.75m back off).

Nothing noticed on the loop after the de-mate message, so I thought they had some set-up to do first, but they went right ahead and did it immediately.
