The Tech Behind Felix Baumgartner's Stratospheric Skydive

MrSeb writes "Felix Baumgartner has successfully completed his stratospheric skydive from 128,000 feet (39km), breaking a record that was set 52 years ago by Air Force Captain Joe Kittinger — that much we know. From the balloon, to the capsule, to the gear that Baumgartner wore during his 730 mph (1174 kph) free fall, the technology behind the scenes is impressive, and in some cases bleeding edge. ExtremeTech takes a deep dive into the tech that kept Baumgartner alive during the three-hour ascent and (much shorter) descent — and the tech that allowed us to watch every moment of the Red Bull Stratos mission live, as captured by no less than 15 digital cameras and numerous other scientific instruments."

    Did you read abou this on Fox News by any chance? You obviously didn't watch the actual footage.

    Felix stabilised the spin manually WELL before deploying his parachute.

    They had a drogue chute ready to help stabilise the spin if it was required but he didn't use it because it could have prevented him from reaching Mach speed.

    If he HAD deployed his main parachute while in an uncontrollable spin it is VERY UNLIKELY that it would have deployed properly, much more likely he would have remained in a spin, not so fast but with his body mass further away from the centre of rotation and hence still massive G forces.

    Yes, it was. At those altitudes, the only thing to prevent spins would be a gas reaction system like satellites use. Aka, vent gas out of pressurized bottles to counter-act unwanted spin. Having those on his suit would have added a ton of weight, and precluded him wanting to do this in just a pressure suit. There's no air or anything to allow him to do it himself. That's why when he jumped, he tried to be as still as possible. Even while spinning, the idea was not to move or react. Just wait until you hit enough atmosphere that you can move your body to stabilize yourself with the drag. When he started tumbling, I was screaming for him to hit the atmosphere and be able to stabilize himself. Then he did, and once that happened I knew that he had it nailed.
