An experienced designer with more freedom to act might have realised that there was just too much optimism in the Ares I concept: that a shuttle SRB was simply too small as a first stage for a rocket carrying the relatively heavy Orion spacecraft.
Solid-fuel rockets can't easily be shut down on command.
Claiming that solid rockets are necessary for a heavy-lift launcher is obvious nonsense.
Sometimes people wonder why aeroplanes are so cheap and rockets are so expensive. Even the most superficial comparison shows one obvious difference: aeroplane engines use outside air to burn their fuel, while rockets have to carry their own oxidisers along.
We're fine, but we did not play well (at UCLA and USC). It's early; we know what we didn't do. It's not rocket science. We'll be pretty fired up.
Rockets fired by the Taliban generally aren't guided.
Rockets are one of the resistance tools. Our people have the right to resist the occupation. The occupation is the problem and as long as the problem exists our people have the right to resist.
Rocket propulsion was explored -- specifically, a turbo-pump-equipped rocket made by Reaction Motors Inc. Delivering 6,000 pounds of thrust, the acid-aniline-fueled engine was believed to be capable of boosting an airplane to the fringes of the known performance envelope,
Rocket might have thrown 10, 20 innings. I think he was prepared to do whatever it took. And that's the way the man is. I've never seen anybody like him. He's amazing.
Rocket got a couple of runs, and it allowed him to be more aggressive,
