Copied form FD 11:
USFJoseph - 19/6/2007 7:04 AM
FD12 Execute Package here
Looks like crew wakeup was at 6:38 ET this morning...
Undocking is set for 10:42 ET this morning...
As previously noted, Atlatis will fly a full 360 degree flyaround after undocking. We should see a very different looking ISS!

Are they doing the Atlantis station keeping attitude tests referred to yesterday by Englehof?

Wow, they tranferred 116 lbs of O2, they mentioned something like 40 lbs would be transferred earlier in the mission when considering extensions. What does EOM+3 mean exactly, is it they have 3 days on orbit O2 after undocking, or after earliest deorbit burn moment or something. when is EOM? (all from last page of Execute package document)

EOM is End Of Mission. I believe that means we have enough oxygen for 3 potential days of landing opportunities in case of a waveoff on the first. That would mean that they REALLY stretched their supplies when it looked like another docked day would be necessary!
EDIT: did anybody catch the crew wakeup?

That was mainly completed on Sunday and Monday.
Atlantis going through a full power up following the power downs in case of extra docking day:

Yesterday Englehof said that they had used more Atlantis propellant than expected when the Russian computers failed and that they wanted to do a test before undocking to see if they could explain why that was (ie they had probably got their predicted station attitude wrong for minimum propellant loss).

Yesterday the thought the weather could force a landing at EDW as thunderstorms were expected around the Cape.

Been looking around the information and nothing sticks out bar yesterday's note:

Atlantis still required for some assist. Helping to gain another 4300ft overnight.
There are no notes of attitude assist or testing this morning, will keep checking, but station keeping could relate to updated flyaround proceedures, which we know about from yesterday (Jorge mentioned it I believe).
I'm probably missing something
So I'll leave this open for anyone else to chip in.

Only saw it in the the status briefing with Phil Engelauf, but I'm catching up...he said that they were planning on handing over attitude control to the orbiter for one hour to (IIRC) get more data on prop usage. Not sure where on the timeline, but the execute package might say...

Will they call up Edwards for Thursday or just wave off 24 hours if the weather at KSC is bad on both attempts? (Sorry if this was already stated and I missed it.)

Interesting. No note of them doing this so far - and they are fast running out of time to do so.

Well, Atlantis is controlling the stack right now, but that's normal pre-undocking, rather than a test. Maybe they are using it as an opportunity to test.
Anyway..
