NASA to Test Emergency Ability of New Spacecraft 126
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."

But was it hubris, callousness, or bean counting? One from each column?
I'm somewhat embarrassed for NASA that they feel the need to press release this. It should be right up there with "NASA To Tighten All Screws On New Spacecraft". Of course you're going to do that.

When we built the previous generations of spacecraft we didn't know WTF we were doing -- Especially with the earliest attempts (made by the US) after the launch of Sputnik; We were trying to get something up fast, not something up safely.
The shuttle has been a compromise since its very inception. It was designed to be able to intercept/capture (as well as launch) satalites. Because of this, it doesn't really go up high enough to be [extremely] useful. Additionally, when we look at the first major shuttle disaster (challenger?), it was due to thermal failure of critical parts (Read: not designed to launch when it was cold out), which lead to nice fireworks.
But then again, my grandfather worked on [pieces of] most of the early space programs (he worked for G.E.), so my opinion is clearly biased...

Soviet attitude to safety (Score:4, Interesting)
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.

No, the crew will not be moving around during ascent.
In short: The software will monitor for abort conditions, at a point where any are detected the Launch Abort System (LAS) will take over and "pull" the CM in the proper direction away from the rocket.
More unofficial info (sorry, cant link to official docs):

(I also remember an animated video on NASA's site at one point, but cant seem to locate it on the new website.)

All three sources say the same thing: 3 of the 4 air packs were activated which can only be done manually.
