NASA to Test Emergency Ability of New Spacecraft
coondoggie writes "NASA this will show off the first mock up of its Orion space capsule ahead of the capsule's first emergency astronaut escape system test. NASA said it will jettison the full-size structural model off a simulated launch pad at the US Army's White Sands Missile Range in New Mexico. The launch escape vehicle sits atop the Orion capsule which is slated to be bolted on an Ares rocket. The escape vehicle is made up of three solid rocket motors as well as separation mechanisms and canards, and should offer the crew an escape capability in the event of an emergency during launch, according to NASA."
they'll have this whole thing ironed out for when that one guy has to go to Mars alone
We figured out a long time ago that it's easier to elect seven judges than to elect 132 legislators.
http://history.nasa.gov/SP-4205/app-c.html#section2 Ah, Saturn V... good times. Glad we've once again remembered it's a better idea to have the astronauts at the TOP of the stack rather than stuck to the SIDE of the stack.
Somewhat offtopic, but I still don't think you should name any space project "Orion" unless it involves nuclear propulsion! It's... misleading.
Columbia originally had ejection seats for the Commander and Pilot for the first few flights. After crews exceeded two people, however, they replaced the seats with normal ones because it wouldn't be fair for only two of the crew to be able to eject while the rest perished.
The summary doesn't describe the system itself very well - if that was how it worked I'd agree it'd be idiotic. The "vehicle" the summary mentions is actually just a separate rocket engine attached to the nose of the capsule. If something goes wrong, the astronauts don't have to go anywhere; the bolts holding the capsule onto the main Ares launch vehicle blow, and the escape rocket fires, lifting the entire Orion capsule off the Ares rocket and high enough into the air to get clear of the launch pad and any unpleasant explosions. Then the escape rocket separates from the capsule, while the capsule is hopefully high enough to land softly by parachute.

The shuttle should have been an evolution from Apollo. Make the orbiter a stretched, winged service module. Install a hatch in the command module heat shield (this was trialled for the Gemini wet lab). For launch and landing pack the crew into the CM using the rescue mode layout. During launch use a launch escape system. This will get you past the Challenger failure mode. During reentry the LES won't be there but you can use the reaction control system to achieve separation.

Interestingly enough, early designs from North American Rockwell for the Shuttle included a crew escape system similar to what was going to be implemented in the North American Rockwell B-1A - which in itself was based on the F-111's Crew Escape Module, where the Crew Cabin / Cockpit blasts away from the rest of the vehicle using solid rocket motors. When the decision was made to use the area where the motors would have been for the extra crew seats and stowage, the whole escape system was scrapped. So much for hindsight.

I don't give a rat's behind about "karma" here or anywhere else. Don't like what I have to say here? Deal with it!
The astronauts are seated in the capsule during launch. The emergency system is basically a rocket on top of the capsule. If there is an emergency, the rocket fires and pulls the capsule away from the stack.

You went to college didn't you? It shows!
It is the same sort of escape system attached to the top of the
capsule as the soyuz spacecraft has. If you do some searching it
is a tried and proved emergency escape system. Look for Soyuz T-10,
a fire on the pad occurred during launch causing a explosion that
destroyed the pad. The cosmonauts where launched to safely by their
emergency escape rockets.

People who have investigated the ejector seats on Soviet military aircraft have commented that in some ways they were better than ones used on many NATO planes,and the armor on Soviet helicopters was truly impressive. After all, who do you think worked on the Soviet space and military aircraft programs? Hint: they weren't heroic Stakhanovite peasants. They were the sons and daughters of Party members, the people who were on top in the Soviet Union. And middle class people are notorious for caring an awful lot what happens to their children.
So I guess what I am saying is, there is no a priori reason for believing that the US and USSR attitude to space flight safety was significantly different, but, as Arthur Clarke once commented, the Russians preferred to go with solid, proven, perhaps over-engineered systems even if they were bigger and heavier.
