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."

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 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.
