I just watched a detail of the space shuttle discovery launch on the NASA channel… pretty cool stuff…. check this out, at the 2 miles mark they were going 600mph…. at 6 miles they were 900 mph and started throttling up…. At 13miles they were 1700 mph and 1.53 seconds into the take off they were 23miles up at 2700 mph… pretty bad ass stuff if ya ask me….

and they go 17,000 mph in space or 12 miles a sec

Kent,
Get on the Nasa channel during the decent process is pretty cool too. I watched when they landed at Edwards a few years ago. I really like the video feeds when they are doing moon walks. the radio communication while they are out there also is pretty interesting also.

23miles in 1.53sec? I don't think so. thats 1 mile in .067sec.

From here in Jacksonville Florida, we watch the first 10 seconds on CNN, then step out the front door and watch it fly by...
Really...

I knew what you meant and I'll bet you would like to drive this one also,

One thing that I've always been curious about. The thrusters on the leading edge of the shuttle under the "windshield". They're an open tube. How in the heck do they make escape velocity with an open snoot?
-
once you pack them full of air, they don't catch as much and easily overcome by millions of HP... :roll:

I worked for the company that made those thrusters. They also made the thrusters for the moon lander and bunches of satellites. All of those thrusters had a life measured in seconds. The shuttle thruster has to last for the life of the shuttle.
The nozzle and injector plate are made from niobium. Neat stuff. If you touch it, no matter how clean your hands are, it cracks when it heats up. They learned that the hard way. Niobium has an affinity for almost everything and has an impressive number of steps in the refining process to produce pure metal. The injector plate is about 4 inches in diameter and has 1012 holes drilled in it.
If I remember right there are 38 thrusters on the shuttle and every one has a different nozzle profile to fit the body profile.
The shuttle is the only plane that was tested at high speed first! Other than the low speed drop test that was done from the back of a 747, the shuttle first flew when it landed after the first flight. There is a period of time around Mach 7 where the controls are not very stable and the shuttle is held stable with no change in direction through that period.
Oh, and it's a dead stick landing with no chance of a go-around.
I still want to fly in it!
