"After 2010, when the station is up and running with 6 astronauts, doing scientific research much more than today, a internal downmass of 10kg per Soyuz (40kg per year) will be enough. And no external downmass at all. Simply amazing. "
First, I think Dempsey said he believed it was the heaviest going up but hadn't confirmed, but it was the heaviest going down.
And no, 10 kg per Soyuz is not adequate - it will severely shape the type of research going on. It is not the desirement, but the requirement.

Just one thing to add to the deorbit prep timeline that Robert/collectspace posted earlier today: go/nogo for fluid loading is usually about an hour before deorbit burn. That's one of the milestones I look for.

My statement was kinda sarcastic.
There it is again, the old logistics problem. We are talking about two orders of magnitude of downmass capability missing. And no realistic solutions in sight (on time).

Was this indeed "debris" that is pictured here? I received an e-mail from a friend who had recorded NASA TV during this same time frame and he reported having seen what appeared to be debris passing the ISS. I would sure appreciate someone commenting about this photo if they had a moment. Thank you.

Very nice videos. Is there a similar site for flyaround stills?

Spaceflight.nasa.gov ought to have the flyaround stills sometime today or tomorrow (at least I hope).

"Plan is to land on Wednesday. KSC is ready to support another vehicle. [PRIMARY] If not at the cape, we will land at Edwards Air Force Base in California [SECONDARY], as we have the necessary support teams at either location. I think Wednesday will be a good day to land." - LeRoy Cain

"Talked a lot about the radiator flex hose before launch. Everyone across the program thought very hard to find a way to launch. Best procedure to closing was normal closure procedures, and should not be a problem during landing."

PAO: Is it an above and beyond achievement to rollout while undocking?
Cain: We knew that between this mission and the next, that the biggest thing was to turnaround the Launch Complex. Pad performance was outstanding on this mission, cleanest since RTF. Key was to be able to get vehicle ready, and the pad to be ready to accept a vehicle.

PAO: Didn't hear a whole lot out of the MMT during this mission.. Is that good?
Cain: Absolutely! The performance of the orbiter and the station has been outstanding. Great tribute to this awesome workforce for an on-orbit crew and rolling out at the same time. Great time to be in this business, never seen people this excited or energized about the program.

Thought I heard call-up of a heater problem with messages to be ignored, but I didn't catch everything.

Just about 20 minutes before Atlantis' crew was preparing to go to sleep, capcom Stephen Robinson called up to the orbiter indicating that a heater for one of their aft vernier RCS thrusters had failed and warned that an alarm might sound as a result.
That call was soon followed by a second warning, this time that multiple heaters had failed. After a brief (routine) comm outage, Robinson asked commander Steve Frick to cycle the switch that enables the heaters, so that the ground could watch if the system warmed while the crew sleeps.

So they're losing multiple aft VRCS heaters? Doesn't that automatically deselect those jets and making the, "NO-GO" for firing? This happened for jet L5L prior to launch of STS-121 in July 2006.

Here is a quick transcript of the second and third calls about the heaters...
"We are looking at all the heaters in the manifold 5 on the aft are now going down, so you are probably going to get three more messages, an L5D, an R5D and an R5R all within the next hour sequentially," radioed Robinson. "No action for you, its not going to reconfigure your aft tail right now. We may have some more words for you on the other side of the comm gap. We'll be back in about 3.5 minutes."
"Okay, we copy Steve, understand that there is no chance to do a heater swap or inhibiting those cautions?" replied Frick.
"Well Steve, there are no other heaters to swap to and when we come back after the comm out, we're probably going to have you try cycling the heater switch. But we want to talk just a little bit more. See you in a bit."
"Atlantis, Houston, we're back with you. Switch to throw, panel A14," called Robinson.
"Okay, go ahead Steve," responded Frick.
"Okay, this is just to see if it happens to be the switch. Panel A14 on the bottom row, is the Aft RCS Jet #5, take to 'Off' with a mark, and back to 'Auto', said Robinson.
"Okay, it is currently in the 'Auto' position, coming to 'Off', standby, mark, and coming back to 'Auto', standby, mark," said Frick.
"Okay, we'll take a look at the data here and see if it warms up, in the meantime you should get those other three messages within the next 25 to 30 minutes. We are not able to inhibit those particular ones but as I said it shouldn't reconfigure your ship at all, once they go, that should be enough," said Robinson.
"Okay, we copy all Steve. We'll punch them off as they come up, all aft tail only, and after the couple we'll be good for the night. Thanks," replied Frick.

Thank you for that transcript, Robert. I had missed this event on NASA TV, was busy with chores and the likes..
Hope the crew sleeps well.. Does this have any effect for tomorrow's pre-EOM checkouts?
