Baumgartner Completes 13.5-Mile Free-Fall Jump, Aims For Record

An anonymous reader writes "On Thursday Felix Baumgartner climbed into a capsule carried by a balloon, floated up to 71,500 feet, and jumped out. He free-fell through the atmosphere for almost four minutes, hitting an estimated top speed of 364 mph. 'I wanted to open the parachute after descending for a while but I noticed that I was still at an altitude of 50,000ft,' he said. After finally deploying his chute, he fell for a bit over four more minutes, before successfully touching down in the New Mexico Desert. This was a test to prepare him for a jump of 120,000 feet later this summer, during which Baumgartner will break the record for highest free-fall jump — and the sound barrier. '... a 36-pound spacesuit is all that separates Baumgartner from a hostile world that would boil the blood in his body. Baumgartner will wear a chest pack crammed with data-hungry instruments to help ground controllers monitor the attempt — and log scientific data. Some will keep tabs on his heart rate and oxygen intake to see how a body in a spacesuit reacts to a boundary no one has broken (and lived to tell the tale): the speed of sound.'"

    The whole attempt will be a win, win situation for him - he's guaranteed to make it into the Guinness Book.

    After the attempt, he'll either he'll have the record for the highest freefall jump, or he'll have the record for the world's largest pizza.

    No. If he survives till the ground it will be the longest free fall jump. Survival is not required for being the first person to break the sound barrier without a means of propulsion.

    Sorry to hear you got bored halfway, bro.

    If this works, maybe the people who were designing things like the MOOSE orbital bail-out system weren't as crazy as everyone thought....

    I'd like to point out that your blood doesn't boil in a low pressure environment, even if that's a vacuum. As it's contained by your skin and tissues that are rather noncompliant tissue and thus maintain a certain level of internal pressure.

    However, the starling forces are severely disrupted, resulting in oedema of any exposed tissue, this however can be compensated for by using skin tight clothing. NASA did in fact once research a wet-suit like space suit that wouldn't be pressure sealed, concept was good, however, if the suit is kinked and the pressure is relieved you get oedema, and this is hard to prevent in regions such as around joints and crotch.

    So basically hipsters can jump from 100,000+ feet safely?

      Kittinger did several flights of this sort. Manhigh I and Excelsior I, II, III. There may have been others. I'm not that well versed on old USAF projects.

      As I recall from interviews I've read regarding the 1st flight, Kittinger was flying blind for a good bit of the ascent. His visor frosted over, so he couldn't see anything, including his altimeter. On the 3rd flight, his right glove leaked, causing his hand to swell. There was no permanent injury from that though.

        While not mentioned in the summary, it's in the story that Kittinger is consulting on Baumgartner's jumps. He's also been planning it for a while. Here's a 2010 story on it.

        As far as I know, there were no failed attempts of this sort. Well, not that resulted in the person not surviving, despite the blurb at the end of the summary. Well, it fails twice in that Kettinger did break the speed of sound.

  9. The Speed of Sound is not 700 mph by iliketrash · · Score: 4, Informative

    From TFA: "Thirty seconds after leaping, he’ll exceed the speed of sound in the thin upper atmosphere by traveling almost 700 miles per hour."

    The speed of of sound in the upper atmosphere is _not_ 700 miles per hour. That figure relates to the speed of sound at one atmosphere and normal temperatures and also has to consider partial pressures including water vapor. In the upper atmosphere, the speed of sound is much less.

    Claims similar to this over the years that the space shuttle is traveling at Mach 25 are just as ill-informed, since the "mach" number is supposed to be based on local conditions, not at some hypothetical place on a beach (one atmosphere, nice temperatures). It is wrong to simply divide some velocity by the speed of sound at sea level and then apply it to conditions present at the object's location.

    Here is what NASA says:

    theory predicts -- and animal experiments confirm -- that otherwise, exposure to vacuum causes no immediate injury. You do not explode. Your blood does not boil. You do not freeze. You do not instantly lose consciousness. Various minor problems (sunburn, possibly "the bends", certainly some [mild, reversible, painless] swelling of skin and underlying tissue) start after ten seconds or so. At some point you lose consciousness from lack of oxygen. Injuries accumulate. After perhaps one or two minutes, you're dying. The limits are not really known.

    You do not explode and your blood does not boil because of the containing effect of your skin and circulatory system. You do not instantly freeze because, although the space environment is typically very cold, heat does not transfer away from a body quickly. Loss of consciousness occurs only after the body has depleted the supply of oxygen in the blood.
