NASA Successfully Tests Orion's New Crew Escape System
Boccaccio writes "NASA on Wednesday successfully tested its MLAS alternative launch escape system designed for the new Orion Crew module. MLAS, or Max Launch Abort System, is named after the inventor of the crew escape system on the Mercury program, Maxime (Max) Faget and consists of four rocket motors built into a fairing that encloses an Orion module during Launch. MLAS is designed to pull the crew away from the main rocket stack during the critical first 2.5 minutes of flight in the event of a catastrophic failure. The advantage of the MLAS system over the more traditional LAS (Launch Abort System) is that it reduces the total height of the rocket, lowering the center of gravity and adding stability, and potentially allowing higher fuel load.
You can watch a video of the launch at the NASA website, and there are also a bunch of pictures."
Jettison + primary escape stage + jettison stage + deploy nose cone parachutes + jettison nosecone + deploy primary parachute primers + deploy primary chutes
Failure of any of those steps results in loss of crew.
I initially thought the same thing, but perhaps they need variable descent rates and perhaps the first set or two of chutes is more likely to get tangled, ripped, or burned. We also don't know if the failure of one system prevents all the subsequent systems from operating or not. It may be more reliable than it first appears.
No, it only confuses pedantic old timers who are unable to keep straight the difference between a project long dead and an active project. The rest of us old timers have no problems at all.
