You also see what is called the "mushroom effect" on exhaust plumes when they go into the lower pressure, higher altitudes. That causes the spreading out of the plume that can actually crawl up the vehicle if the exhaust nozzle does not have enough expansion. This makes for some awesome launch pictures when the vehicle climbs into the sunlight after a post sunset launch.
The SSME's are also being throttled down during this period because they will be pushing too hard against a lighter load and they need to maintain <=3G's. The engines are burning hydrogen rich, not at an optimum mixture ratio, and you will get more visible exhaust products.
The RCS is firing pretty often during ET sep along with the MPS venting and it makes for a pretty spectacular display.
However, I don't remember any other ET video showing this much venting/firing.

All has to do with the sun angle.

Just ignore the ignorant mass media who sensationalize minor events in futile attempts to mess up a good thing. Nobody really cares what they think.

15 minutes from the NC1 burn. Wonder if we'll get PLB footage for it! Would be real nice!

Debris report: Pretty clean launch, did see a few pieces of debris (at least 3) on the LH2 feedline [from what I hear]. Did not see an impact at that time, but obviously being looked at.
Let's hope Marcia "They're all gonna die!" Dunn hasn't seen that yet...
EDIT: and the shot directly above this post... NICE! I see fluffy bunny clouds! (incidentally, did anybody else notice the shapes of the clouds before launch? I saw a goose, and Bill the Cat, and 8 or 9 monsters!)
Okay, so I'm a bit delirious. I'm home from work with the flu.
The goose was really cool... several people here commented on it...

Sad that this isn't true. People who don't know better see it, believe it, and tell their Congressman NASA is screwing up and the money is spent better elsewhere.

I should clarify. Nobody who knows anything about NASA and what they do cares what they think. Also, no one who has seen this chart cares what they think.

BBC reported that a spacewalk might be required to inspect possible damage. Someone should tell Nasa about this spacewalk :laugh:

NASA reports the BBC needs to get back in the airlock and come back to Earth.

NC-1 coming up. It's a two-engine OMS burn with ignition at MET 00/03:37:17.4, which I believe works out to 23:22:47 UTC. About 20 minutes from now.

Ha ha. Spaeking of a mushroom effect, I snapped this image about 5mins after launch. I thought it was funny seeing as how the potential force of the shuttle is often attributed to that of a small nuclear weapon.

I took these pics a little less than four hours ago from Banana Creek. What an amazing and awe-inspiring sight!

NC-1 completed OK; no live audio as PAO was focused on the ISS crew at the time.

Welcome to the site Lord Kinbote. Thanks for sharing the great shots! We haven't seen many images of the launch yet so these are always wonderful to see.

Hi everyone!
Long time lurker, but if anyones interested, here's my youtube vid of the launch
