    And in that spirit:

    T-22h

    btw a very civilised and constructive press conference on NASATV. Clear words on the why of the ISS.

    It's very interesting to hear somebody talking who has the knowledge, is intelligent and most importantly does take the time to think about his answers.

    Ha! That's just the time until launch, weather permitting - who's interested in that? The official countdown is at T-11:00:00 and holding; it should restart after the RSS has been swung back this evening.

    Ok let's feed the roll:


    T-7.45 and COUNTING.

    *yee-ha*

    T-6.00 scheduled hold

    This built-in hold typically lasts two hours.
    Launch team verifies no violations of launch commit criteria before loading the External Tank with propellants
    Clear pad of all personnel
    Chill-down of propellant transfer lines
    Begin loading the External Tank with about 500,000 gallons of cryogenic propellants

  6. #6
    T-4:49 and counting.

    Next hold:
    T-3 hours and holding
    This built-in hold typically lasts two hours.
    Perform inertial measurement unit preflight calibration
    Align Merritt Island Launch Area (MILA) tracking antennas

    This will be the last big hold; after that the holds take only some minutes during a nominal launch.

    The launch pad is cleared, the fuel tanks are full - she just needs the crew and she's ready to roll.

    Oh yes, and the weather prospects have improved to 40% chance of delay, now more likely than not to launch today.

    Crew on its way.

    I see some not too small clouds, but not a lot of wind apparently. Are clouds of importance for shuttle launches as was the case for tracking NH?


    The shuttle looks very clean and shiny. Too bad the tank has its typical rusty colour, in white it was a really nice package.

    Funny how we got to know the intrinsic rusty colour of the tank as if it is part of the paintjob .

    Is WMP the best choice for optimal NASATV playback quality?

    It's the foam colour, isn't it? so it is an application.

    Small clouds I think are OK but the heavy cu-nim storm clouds are showstoppers for sure.

    I hope this goes well for everyone, it will be good to see the USA's manned space program going again

    I am so used to the sighttht I did not notice it, but THIS BABY is standing right in front of me. Quite appropriate .

    Are the cunimbs a problem because of the winds inside, probability of lightning or optical reasons?

    For NH the cloud deck was an optical tracking showstopper.

    The sky seems more blue now.

    Cute, although it immediately makes me think: How many things are wrong with this picture?...

  14. #14
    that's perfectly explained by heiligenschein from the wooden panel. Having a non-retractable undercarriage would make for "some" engineering issues indeed. The same goes for a control room at 10 meters from the platform .

    You could see the foam as a coating of the tank system indeed; I saw tank+foam as the basic system that could or could not be painted. Not relevant .

    Again some very nice looking clouds now, not so nice for the launch though.

    I missed the statement because I was playing on my theatre organ .

    How long is today's window, 45 minutes?

    atm the weather allows for launch.

    "the astronauts are awake". <----a very important prerequisite for a successful flight, that is easily overlooked .

    One thruster heater has failed, meaning that this thruster has failed. They're looking whether they can go on with the mission while this thruster is failed, especially whether they can dock. If docking is possible, they can think about means to solve the issue in flight. Maybe the thruster is not necessary at all.

    As we all know, every mission needs to have an issue .

    I watch launchs on C-span. (My cable outlet doesn't provide NASA tv.) I prefer it to the cable networks because of the lack of the "talking heads" who can't seem to help but "blather on" about nothing.

  18. #18
    I watch NASA TV via the internet. It is indeed refreshing, but a relief to actually have nobody talking when nothing is to be said.

    Some nice footage of thruster valve tests or something like that now.

    Did the narrator just say

    "and in that room they've been spending the last 3 days of their lives"??

    Could have chosen better words

    Weather looks fairly good. *yes*

    T-3 hours and counting.

    The astronauts are driving in that beautiful bus towards the platform.

    Weather triggers go/nogo now. It's NH all over again. Where's Sticks to doom the mission?

    What's the point of scheduled holds? If you plan to stop for a certain amount of time, why not just add that time into the countdown?

    Ban Sticks from launch threads.

  24. #24
    ^^^^^^^^
    Ladies and gentlemen, I proudly announce the arrival of a rule n&#176;6

    Pff, his words of doom could not stop NH from lifting off. HA!



    The astronauts are getting into the shuttle.

    I'm not going to count the times I hear the phrases

    "a great shot of..."
    "a tremendous shot of..."

    Make it a drinking game. You'll be stone smashed by liftoff...

    Interesting to note this looks like a return to a three man station crew.

    The perspective from a vertically placed shuttle, with the crew in their seats and the personnel standing between them, is quite beautiful and confusing .

    I hope to see construction units brought to the ISS soon. Finish that beast. It's already to be smaller than intended, but still it's only fully useable with complete crew and (according to most recent plan) fully constructed. Finish it now in order to make the most out of this investment.

    Launch is getting close!

    From what I gathered from the live feed, this mission is taking the gear needed to expand the life support system to six, so they're getting REAL confident in having the foam issue resolved.

    For those who like video quality (as opposed to RealPlayer) and have a US cable system, I just noticed that space historian Roger Launius was on C-SPAN, and they plan to switch to the NASA TV feed full-time about 20 minutes before scheduled launch. (On the other hand, Jim Oberg is working from an MSNBC broadcast booth in a trailer near JSC, but then our cable system doesn't carry MSNBC...)
