I expected the CDR to stay inside and orchestrate

Well well, this is getting exciting!

Just for clarity, that would be 0715-1300 on Saturday, May 11th in the US Central time zone (Houston MCC).

Someone check my math on that, it's early here.

Do we already know something about specific tasks?

I assume task #1 will be translation to P6 and inspection. But what comes next?

EVA briefing package (the same one sent up to the ISS crew) now up on L2!

I see that Cassidy and Marshburn transferred cargoes from the crew lock to other places and now preparing EMU suits for EVA-21.

Article for Pete going on as soon as I get images into it. I'll then rework this thread to how it should actually be.....

Space Pete · « **Reply #8 on:** 05/10/2013 09:12 am »

Cassidy and Marshburn prepping the A/L and EMUs.

Chris Cassidy is not the ISS commander, Chris Hadfield is.

To clarify, I did expect the ISS CDR, Chris Hatfield to stay inside and orchestrate the EVA.

Pete Harding's amazing article for this situation and the EVAs:

Thanks Pete for the article - so much more information than the usual news sites!

Targeteer · « **Reply #12 on:** 05/10/2013 10:20 am »

Somewhat OBE at this point but Hadfield's Facebook post is the only "official" notice of the EVA I can find. There is still nothing on the NASA website...

(Evan's note) The crew has woken this morning and have begun immediate preparations to do an EVA (spacewalk) to fix the ammonia leak.

Crewmates Chris Cassidy and Tom Marshburn are preparing suits for a trip outside. You can watch and listen to them preparing here (when the camera isn't showing blue screen) - http://www.nasa.gov/multimedia/nasatv/iss_ustream.html

Excellent overview article Pete! That is why this site is the best!

And Targeteer, even ESA site is not official with news yet! It is of course official anyway.

Waiting for PAO to come to work at Houston I guess

If I got this right, then its important to note:
Tomorrows EVA will assess the damage and then if applicable, change the pump module. After that, it will still require an amount of EVA's (one or more) to refill the system with ammonia and then re-pressurize it with nitrogen.

I despair at the mainstream media sometimes:

If they can't even get the right space station (last image), what hope do we have!

anik · « **Reply #18 on:** 05/10/2013 11:48 am »

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

Anik: any word on delay for landing and launch for next crew? Thanks.
