Um, because it's required to achieve orbit. If NASA was all about shooting stuff up into near space and let it fall back to Earth than such speeds wouldn't be requried.redd said:But why does NASA continue to demand such huge velocities to launch a/c into orbit, which require the decelerating re-entry tactics?
Its not NASA that requires it, its physics and gravity that doredd said:But why does NASA continue to demand such huge velocities to launch a/c into orbit, which require the decelerating re-entry tactics? Why are they still utilizing the same rocket/missile technology as they did in the 1960's?
redd said:Okay, point taken, but what I mean is why not refine the methods to acheive all this? We've had two shuttle break ups, the riskiness of the methods to slow the a/c down, and the way in which decelerization occurs, could use revision. Doing things the same way they have always been done may lead to other shuttle accidents, what can NASA do to be flexible and innovative enough to acheive better results here? Rutan seems to be unhindered in developing cutting edge new technology.
Didn't rain down in peices over Texas, though.The pilot of SS1 stated that when he was at max altitude, he heard a loud noise.
He looked back and saw a section near the back that had buckled like a coke can.
