Congatulation
for the perfect lift off from the spaceshuttle Discovery.
I wish I could see the start from Kennedy Space Center...
let's hope anything goes well and she comes sure back to the earth in 12 days

Definately....to all of the above.
I just wish I could have seen it. We're about 2 hrs north of Kennedy, but with the cloud cover & all the oak & pine trees, I couldn't see anything.
Gonna have to take off work one of these days and go there to see it. I hear the roar of the lift off is enough to chill you to the bone.

hey, i can go 20 light years on a tank of diesel. granted, thats not carrying any satelites or extra astronauts, and not having to run from the steller cops. 
yeah, i'm glad too the shuttle got off without any problems....i had some SERIOUS doubts. i was under the fall path in east texas of the last one that went down....very sobering to see it happen.

Well I was listening to it on the radio this morning on my way to work and it was something like 1 minute 30 seconds after liftoff and they said it had burnt something like 84 MILLION POUNDS of fuel. I think at that point it was only 9 miles up. Somehow I doubt I could ever get my Expy to get that bad of milage.

Here are some things that I found out about the shuttle fuel usage.
If the main engines pumped water instead of liquid oxygen and liquid hydrogen, an average family-sized swimming pool could be drained in 25 seconds.
Each engine can generate almost 400,000 pounds (1.8 MN) of thrust at liftoff.
Total Liftoff Thrust: 7.82 million lb / 34.8 MN
Main Engines: 400,000 lb / 1.8 MN each (x 3) = 1.2 million lb / 5.3 MN
Solid Rocket Booster: 3.30 million lb / 14.7 MN each (x 2) = 6.61 million lb / 29.4 MN

I must have misheard this morning, cause the info on wikipedia says the External tank and solid boosters together only weigh 3 million pounds.
Here's a couple more facts I dug up from the Wiki:
The external tank that supplies the main engines during liftoff uses 17,592 US gallons/minute of liquid oxygen and 47,365 US gallons/minute of liquid hydrogen at full boost.
Each solid rocket booster consumes 1.1 million pounds of fuel during the launch.
