Shuttle Launch
Anybody catch the live shuttle launch of Discovery tonight? All I can say is WOW, what a show. I don't even have HD, but the coverage on Fox was the best I have seen of any launch.
They have cameras mounted on the vehicle and on the boost rockets. Fox had a status bar with vehicle speed and altitude in real time. From the distance they film, you really don't get an idea of how fast the thing accelerates. It was doing 1,700 fps almost immediately, well in a few seconds anyway, which is approximately the speed of a .357 magnum. And of course went up from there. The coverage continued until it was around 25,000 fps and 250,000 feet elevation. The cameras onboard the booster showed the boost rockets falling away and the shuttle moving away under its own power.
Quite an impressive show!

For the record, it was Endeavor, and not Discovery as I said above.
37 million horse power!!!
I found the video, maybe, I hope the link works. They don't make it very easy to share.

17,000mph / 60 minutes = 283.333 miles per minute / 60 seconds = 4.722 miles per second

it wouldnt load.....i am just saying that it would take some distance to get to that speed, and 60 feet isnt a lot of it. but it is really fast.

well steves speed is the speed if it hits the starting line going 25,000 FPS, you have to adjust for acceleration from 0, which means you have to know how fast it is accelerating, which im not sure of but if in 10 seconds it is going faster than sound im sure its quarter mile is pretty freakin quick!!! so if it was going full speed already and hit the starting line it would take.05 seconds, thats like a quarter of a second right, half of a half i think. to get to the end of the 1/4 mile course...man thats mind blowing

no it is 1/20 of a second is what .05 is. heres the math .05 is five onehundredths 5/100 reduced down to 1/20, and if you dont know for sure that i am right: http://www.webmath.com/cgi-bin/fract...dec2fract.html

Thus far, we don't have enough data points to solve a 0-60 equation. Not even with fractions. If you studied the video close enough, you might be able to determine the ignition point, but I doubt it, and that's just one missing data point.
