"The liquid oxygen tank contains a separate, pyrotechnically operated, propulsive tumble vent valve at its forward end. At separation, the liquid oxygen tumble vent valve is opened, providing impulse to assist in the separation maneuver and more positive control of the entry aerodynamics of the ET." from http://science.ksc.nasa.gov/shuttle/technology/sts-newsref/et.html
FWIW, that reference is way out of date...I believe the tumble valve was deleted from the tank a long time ago...
Edit -- I'm going to post a link to a Usenet thread on this in the Q&A thread...

The venting in this video really does make this spectacular...
Where can I find the video?
Look for John44 to post it, hopefully. He has been posting links to those videos in
this thread.

The venting is extremely cool (woo hoo! something I haven't seen before)... Actually looks like the ET is sending out cartoon sound waves (I'm sure there's a better comparison, but I can't think of it.)
And how about that barrel-roll ice debris?
I thought it looked like a comet when it was venting! That was the by far best ET handheld video so far! This flight is just getting better by the minute!
where did you see the venting video/photos? cant find em anywhere

They are referring to handheld video shot by the crew after ET separation...it was downlinked a couple of hours ago and went out live on NASA TV at the time...
...NASA TV is currently running FD1 highlights. If you can view NASA TV, I would expect excerpts of the handheld video of the ET to show up in the highlights in the next few minutes. (It's now 9:15 pm Eastern.)

ahhh yes, i remember hearing it on the radio channel as i was driving home, didnt see it though. im sure good ol jester will have it up in no time
ok, seen it on the replays, wow!! that was cool. i didnt even know the tank did that.
it would be neat if it were possible to watch the tank as it falls all the way and begins to burn up and see it start to break up and such.

A portion of the ET video is running right now at the very end of the flight day highlights -- it will be replayed multiple times overnight during crew sleep...

As a newbie to the forum, just wanted to say a huge thanks to all that have contributed to this thread for the launch and flight of 122 thus far, and indeed to everyone that has made today's remarkable event possible!
I'm in the UK but have been glued to NasaTV online for most of the day, and the information, pics and commentary on this thread have been the perfect accompaniment to the visuals and sounds on NTV.
I'm planning to come over late August and [hopefully] view the STS-125 Atlantis launch, and it's been exciting today to see Atlantis finally get off the ground with Columbus... and what a superb launch it was.
Thanks again!
Steve
P.S. I've followed missions before but 'Spaceflight' is undoubtedly the best website for the job, will be subscribing to L2 very shortly.

the venting was from the intertank area which would mean it is H2

Its a slim chance, but i may know who you are. Who are you contracted to shoot for? NASA or a 3rd party? I would love to talk photo with you, be sure to check my EXIF info.

That venting tank was more than worth my 6/10s of a percent, how great would a full percent look?

Haha, rule of 3rds my friend! I can NOT center things for the life of me - it really bugs me. I was shooting at anywhere from 3-10 frames per second, so i have a lot of options as far as orbiter placement in the frame, i just started to edit that one.
