Flight Day 12 TV Schedule:
-
If this was somewhere else, I haven't found it... Anyway, PAO just announced that Atlantis has the heaviest mid-deck load out ever for both launch and entry on STS-122.
-
Yeah, Bob Dempsey mentioned that during today's Mission Status Briefing. He said it was ONE OF (not THE) heaviest going up, and IS the heaviest coming down. I believe the mass was 2400 lbs. It might have been 1400 lbs., but I think that was the water transfer number.
-
Wake up was at 11:53 PM CST. The song was Over the Rainbow (not the Wizard of Oz version) sent by Dan Tani's wife.

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.

Potentially moving up the undocking 10 minutes or so, because of arrays feathering being faster than usual. Right now, taking test distance measurements.
-
ISS crew are awake, have performed their DPC and started more Columbus outfitting. They also have some off-duty time after these hectic days.
-
The determining factor to undock is now the feathering of the Russian arrays, that can be as early as 10 minutes before the scheduled undock time, or as late as only 2 minutes before that time.
10 minutes of Ku after planned undock time.
-
Details for the 123 rollout coverage:
-
ISS ready for undocking.
-
Shuttle ready to undock as soon as go is given.
-
Go for undocking at nominal time. Still waiting on arrays. Scheduled in 18 mins.
-
Around 15 minutes until scheduled undocking:
-
Russian Array Wings are in the proper feathered position.
-
A couples of minutes from undocking.
-
-
Dan Tani and a spinning camera...!
-
Go for undocking sequence initiation (3 minutes earlier than the expected time)
-
Solar Array Wings all in position, undocking in about three minutes!
-
Dan on the flight deck.
Go fo undocking, arrays all in correct config
-
Too slow, I´ll leave you guys to it. :)
-
Wonder if we'll keep this as we undock...
-
Undocking started!
-
Hooks being driven out.
-
PHYSICAL SEPARATION!
-
Physical separation confirmed.
-
Station now in attitude control!
-
ISS in attitude control.
"Atlantis departing" bell ring :)
-
Ding ding ding "Atlantis Departing"
-
Atlantis departure bells!
-
20ft separated:
-
-
RCS reactivated.
-
Steering jets have been turned back on.
-
40 ft
-
-
Total docked time: 8 days 16 hours 7 minutes
Dan Tani: 107 days as an Expedition crew, 116 days at ISS
-
Still backing out, SSV shots right now.. Hoping we have KU for flyaround! (And DAY!)
-
135 ft
-
-
There´s that Peggy, ahead of the timeline again, ready with PMA pressurisation activities before the shuttle has moved to the required range. She´s quick!
-
Radar will not be used until after the 1st sep burn (crew choice). Benefit for us bystanders is that we may get more live video.
-
-
223 feet and counting:
-
Now a shot in MCC-H, you can see them progressing to the flyaround, currently on the V-Bar, or the motion of travel.. 370 (??) feet away, backing away at .2 feet per second.
-
Daylight!!
-
Peggy GO for step 6 of PMA depress, she was holding there.
What a gorgeous Station, don't you think? :)
-
Flyaround initiated. One lap!
Yessir, eeergo!!
-
Flight Deck video!
-
KU through Centerline Camera!
11 minutes ahead of the planned timeline!
-
WOW!
-
BEAUTIFUL SHOT!!!!
-
440 ft away from the ISS:
-
Another stunningly beautiful shot!
-
-
Damn, awesome shots with the Earth in the background.
-
Hmm, back with SSV.. Not as good of a shot now :bleh:
-
Just imagine the hi-res photos that are coming up!!
-
-
Interesting that flyaround is at 470 feet (at the moment) I recollect that this is usually at 600 feet, the annular track on the graphic also indicates that this is inside the usual range.
-
600 ft
-
At 6:50 AM CST, they will downlink the replay of the undocking and flyaround!
-
-
I'm not certain, but I believe they shoot to be at 600 feet at the - Rbar point. This is exactly what the green line on the flyaround screen was indicating.

-
Some camera issues, I would assume (hint: look at the SAW.. and no, it's not a real SAW issue, just a camera issue.. Thought it was funny :bleh: ):
-
Could really see the Zarya SAW moving!
-
Another great shot!
-
Intersecting negative V-bar, 3 quarters of a revolution completed.
-
-
-
-
It's some sight now, I can't imagine how spectacular it will be when completed, especially after 119!
Great view of the Shuttle over the Mediterranean.
-
Now passing over parts of Europe
-
Thanks for the module, Atlantis.. See you later!! :cool:
-
Now going through SSV (Sequential Still Video).. So far, looking good on the flyaround!
-
Who's the pilot for flyaround, Frick or Poindexter?
Nice view of Italy!
-
Hmm, fast flying debris!
-

The pilot for the flyaround is first time flier, Alex Poindexter.
-
Poindexter. The pilot traditionally flies the departure from the station.

Gotta make something happen at 5:30 in the morning.. I didn't get up for cruddy shots! ;)
-
Separation burn coming up.
-
Atlantis will move to a holding position 40 miles from ISS.
-
Great flyaround, Poindexter!! 'Specially for your first flight!
-
Heading into orbital sunset and orbital night:
-
-
Not sure what the last shot was, but here's a great shot of the radiators!
-
Some more great shots:
-
Range = 1500 feet.
-
-
-
Atlantis now departing at about 3.5 fps
-
No need for rollout coverage today from NASA TV (from my perspective...), as Endeavour is already at the pad. Would be nice, though, to see a shot after dawn!!
-
On the graphic we see here, What is the difference beteeen the yellow & green traces?
-
"Light duty afternoon scheduled on the ISS"
-
5 minutes to second sep burn.
-
4002 feet away from the ISS, and separation burn 2 coming up in about 5 minutes. Atlantis will perform LATE INSPECTIONS at the 40 NM mark, that way if anything comes up, they can make an emergency dock at the ISS again.
-
Sep 2 at MET 15:16 even.
-
Sep 2 in progress!
EDIT: Sep 2 complete, no trim required!
-
2nd sep burn complete. Good burn.
-
Dex giving thanks to all the people in MCC-H.
"Flyaround was by the books.. Great job on the PROP usage!" - MCC-H.
-
Nice words from Frick to the Flight Control team.
-
Atlantis now 7000 feet behind the ISS. Atlantis now disabling Rendezvous Nav.
-
Coming up on a handover, could be ratty for 10-12 minutes after.
-
Now shots coming from the payload bay:
-
-
Thanks for the coverage Ford Mustang! The flyaround of the station is my favorite part of the mission, but I wasn't able to see it live.
Are they going to replay the flyaround now or is it delayed for some reason (sorry I have no sound here)?
EDIT: replay started right after I posted :)

It is coming up soon. Right now is the replay of the undocking, with flyaround after that, I would guess.
-
And we now have a live shot of Endeavour at the pad! Simply BEAUTIFUL shot!!!
-
Well.. Great flyaround and undocking, STS-122 crew! Time to get ready for school now.. :(
-
-
Camera is shaking..., looks very strange
You can't really see on the screenshots, probably a bad transmission

Couple more nice shots of Endeavour on the pad.

bish48 - 18/2/2008 4:51 AM
On the graphic we see here, What is the difference beteeen the yellow & green traces?
The yellow trace is derived from the orbiter's rendezvous nav state vectors.
The green trace is filtered Trajectory Control Sensor (TCS) data.
And you didn't ask but I'll tell you anyway, the cyan trace is raw radar data and the magenta trace is handheld laser data.

shaula1247 - 18/2/2008 4:01 AM
Interesting that flyaround is at 470 feet (at the moment) I recollect that this is usually at 600 feet, the annular track on the graphic also indicates that this is inside the usual range.
The crew can start the flyaround at any range over 400 ft on the +Vbar (in front of ISS/on the left of the graphic). They allow a small opening rate to continue so that they hit 600 ft around the time of arrival on the -Rbar (above ISS, on the top of the graphic). Once at 600 ft they remain between 600-700 ft for the remainder of the flyaround.
-
Mission Status Briefing is underway w/ Lead Flight Director Mike Sarafin.
-
Heat Shield inspection underway. OBSS will be stowed after that is complete.
-
Standard search for orbital debris ongoing. Results within a day. Wednesday landing weather is generally favorable. Models, trends look good after a front passes through.
-
Tomorrow crew will prep cabin for reentry (stowage).
-
Landing stategy not yet decided (regarding will they land at Edwards on Wednesday if KSC is not available due to weather). MMT will decide that today.
-
Normal deorbit prep is 4 hours of prep and 1 hour from TIG. (not counting post sleep activities). Each additional orbit adds 90 minutes. If no landing made at end of day, still need to back out of deorbit configuration (open PLB doors, etc).
-
Food and LiOh are sufficient. Oxygen and Hydrogen for fuel cells are limiting consumables. Only enough for 8 hours past Thursday. Not enough for a Friday landing in current predictions. Edwards weather is also looking good Wednesday.
-
Why so much confusion on the landing day in the MSB questioning? Did I miss something?
Weather will be great Wednesday at KSC, with sunny skies and light winds...
-
Questions are focused on certainty of landing on Wednesday. Mike has said MMT will decide. But also said "we will do our best to land" on Wednesday. (I lost the last few sentences of his answer due to internet connection problems).
-
He said that they always can have a technical issue pop up which would push them back a day even if weather is good. Emphasizing (again) that they don't HAVE to land Wednesday.
-
Post MMT briefing at 3:30 Eastern time. Look for more questions about landing Wednesday for certain (except in case of technical difficulties) or about possibly staying on orbit until Thursday if KSC weather is bad on Wednesday. Reporters basically fishing to see if mission is time limited by DoD plans to shoot down the failed satellite.

"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.
-
erioladastra - 18/2/2008 5:32 PM
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.
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).

"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.
-
Replay concluded, now with live shots off of the ISS:
-
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?
-
And not to take away from the current RCS issue, going to post some inspection stuff from this morning, which nobody posted about:
EDIT: And as I post, the highlights go off. Oh well, more next hour! :laugh:
-
FYI, NASA.gov has posted landing ground tracks for Wednesday:
http://www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts122/news/landing.html
-
Currently in MCC-H, handover between Orbit 2 team to the "Planning" Team. Atlantis' sleep period officially happened just under an hour ago.
-
PAO just noting "no joy" on the switch cycle they did on the aft 5 heaters.
-
PAO just said there was no joy in recovering the heater (that they flipped off and on). Still well above danger temperatures.

Any idea what the redish things are up by Canada on the long range tracks?

The jets can still be used.
The real issue with failed heaters would be the injector temperatures or propellant line/manifold temperatures - depending on which heaters have failed - the Mission Control Center can monitor these temps. Lack of heaters and infrequent firing can possibly allow the temps to go out of limits.
Maneuvering the orbiter to a more thermally friendly attitude or intentionally firing the jets for small durations to warm them up are some of the options available.
Bottom line is this is not a major concern at this point.

The crew can start the flyaround at any range over 400 ft on the +Vbar (in front of ISS/on the left of the graphic). They allow a small opening rate to continue so that they hit 600 ft around the time of arrival on the -Rbar (above ISS, on the top of the graphic). Once at 600 ft they remain between 600-700 ft for the remainder of the flyaround.
Thanks. I couldn´t find pictures of earlier tracks to compare.

There are relative motion plots in Section 1 of the Rendezvous FDF, which NASA has made available here:
http://www.nasa.gov/centers/johnson/news/flightdatafiles/foia_archive.html
The undocking/flyaround plot is the last one in Section 1. The 600-700 ft flyaround started with STS-115; the longer range is required to reduce RCS plume impingement on solar arrays outboard of the alpha joints. Previous flights used a 400-500 ft flyaround range.
