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, each capable of producing 120,000 lbs of axial thrust 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.Read more of this story at Slashdot.
