SpaceX Testing Passenger Escape System Tomorrow
An anonymous reader writes: On Wednesday, SpaceX will be performing the first test of a prototype for its passenger capsule escape system. Most rockets have a launch abort system that will save the lives of its crew within the first few minutes of launch, but not beyond a relatively low altitude. SpaceX is designing the new system to be able to return astronauts safely whether they're close to the ground or near orbit.
The Dragon capsule will fire eight SuperDraco thrusters, capable of producing 120,000 lbs of axial thrust between them in under a second. With that amount of thrust, the capsule can get half a kilometer away from a failing rocket in under 5 seconds. SpaceX will have 270 sensors aboard the prototype, including a crash test dummy. The main mission goals include: determining the best sequencing for the launch abort timeline, getting all eight thrusters to fire in unison, and seeing how an aborted launch affects both the inside of the capsule and the area around it. The test is planned to start at 7 a.m. EDT (11:00 UTC), but they have a 7.5-hour window if there are minor delays.

Don't tell anyone, but I'm from the future and wanted to give you a heads up how it goes:
Test 1: Make sure all thrusters installed pointing out.
Test 2: Humans can only withstand how much thrust?
Test 3: Make sure to thrust away from, not underneath, falling debris.
Test 4: Emergency homing signal for safe landing should be changed to not match Arbys drive through wireless mics. "Smoked with real smoke from real wood that's on real fire" ended up being a grimly accurate tagline.
Test 5: Turns out Ed was right and we really do need to add a laser canon for those damn pelicans.
Test 6: Success!
