Nice toy. Finocyl grains. Love to see the thrust curve for this bad boy.

I hope that no budget problems will interfere with The New Constellation program.

Thats looks like she could blow the shuttle's rocket boosters out of the water dude.

Is the housing mounted above the mirror @1:19 another camera or some other instrumentation (heat, pressure)?

22 Million Horse Power. Glad we know in case we ever have to get enough horses to hook up to launch the ARES into outer space. :) - Why do we even count things in horse power any more. In case we have to go back to the horses and need to know how many horses we are gong to need?

For official purposes, we don't use hp for anything. It was merely an attempt to reframe the power of the motor in terms that most people can relate to. :)

Maybe they avoided glass so it wouldnt shatter (too much) and interfere with their data for the propellant.(He says the mirror will end up on the hills! ) At 38 sec, you can see the distortion. I was surprised how large a mirror they were using-but size DOES matter. With a not-flat mirror, the more surface you use, the less noticeable the distortion will be. They KNOW its symmetrical. There are multiple cams and are more concerned with the "eveness" of the ignition and thermal analysis .

A point of clarification: the mirror is totally destroyed by the test. The post you see under the mirror is set into a one-ton concrete block, flush with the ground, and that block will end up halfway up the mountainside when the test is over. The test firing lifts that block out of its recess and hurls it several hundred yards.

Why does the high-speed camera view look so distorted? That is, it's not a nice, circular nozzle and grain.

It is due to the mirror, though as pholourd notes, we don't usually see that sort of distortion. I presume a problem with the mirror itself, but I'd have to ask the camera crew when they get back.
