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."

Re:Too many stories

To be fair, they point to different articles which happen to be on the same subject. The first was all about the jump and links so we could watch it, the second is all about the tech behind the jump. Personally I liked both posts. But if I hadn't liked the second post it would only have taken up a few seconds of my day to figure it out.

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.

Re:Hydrogen would have gotten him a lot higher

What makes you think they wanted to go any higher? They infact had to vent out helium, by opening valves, so that they dont go any higher than 128K ft.
