Felix Baumgartner's Supersonic Skydive Attempt

First time accepted submitter madcarrots writes "The Red Bull Stratos space jump is about to take place. The balloon is filling up and launch is expected around 10 AM MDT. Check out the live feed of the inflation process... it's beautiful!" After some delays it looks like the jump is finally going to happen. UPDATE: The jump was a success. Baumgartner is on the ground and apparently fine.

      Something was still off between those two on communications. I think Joe was trying to put him at ease, probably had direct view of his heart rate and other things we couldn't see. But I think Felix was having a fight or flight moment. I actually worried something with his suit pressure was wrong because he was acting like he had nitrogen narcosis ( or the equivalent at opposite extremes of pressure). He was slow to respond, and sometimes didn't respond or acknowledge at all. I can't help to think if this was a NASA or military exercise, they would have stopped the egress checklist and switched to a "is our pilot ok" checklist. It was painful to watch.

      I'm certified as an Enriched Air diver and you are a bit confused. It's the partial pressure of Oxygen that will kill you. The safe limit we dive to is 1.6 atm partial pressure of O2. This means that you could breath pure O2 in about 20 ft of water. Below that it's toxic.
      In spacesuits they breath pure O2 at about 3-4 psi. The reason is if you put in other gases your mixed gas pressure will be too high and you can't move in a flexible suit. If you go too low you are in trouble too.

NASA has totally failed to capture the imaginative of kids these days, even though decades ago they were doing things very similar to this.

    Why don't they use Hydrogen for things like this (one-time use balloon) and preserve more Helium for scientific and medical use (and for safe party balloons)?

    Hydrogen has been largely discredited as the root cause of the Hindenberg disaster, is it possible to use it safely in a high altitude research balloon?

      Well, I'm more interested in the medical usage - about six months ago, my dad had to reschedule an MRI, the imaging center said that there was a shortage of helium needed to run the unit. He had a non-critical need for his MRI so rescheduling was not a problem, but I have to think that the 30 million cubic feet of helium that they are venting to the atmosphere in this thrill ride would keep a lot of MRI machines running.

      Why don't they use Hydrogen for things like this

      Aside from the obvious hair shirt trolling, you can talk to the ham radio guys who launch balloons with radio repeaters slung underneath them.

      You'd superficially think the very slightly lower weight of H2 would make H2 lift more than He, but after all manner of handwaving it turns out that very cold low pressure helium displaces more air at altitude. So 100 Liters of H2 and He at STP, hauled up 100Kft, supposedly that results in a slightly higher volume of He than H2. I honestly don't care enough to research it, but urban legend or no its an entertaining story. And you're not solving it with ideal gas laws (need non-ideal gas laws/tables)

      Because H2 comes from natgas and He comes from natgas the obvious next calculation is if the larger balloon outweighs (get it?) the advantage of cheaper filling.

      You could probably create a whole low level undergrad or maybe AP high school science lab out of determining if the first claim is true or made up and secondly which would overall as a system be cheaper aka less damaging to the environment.

      Except that medical grade helium and the crap they fill party balloons with are two different things.

      Helium is an element. It won't break down, and actually due to being helium it won't even form compounds. The only problem is that it leaks into space, never to return.

      If helium is mixed up with other elements you can purify it. Compared to purifying gold ore it's probably child's play.

      The line about balloon helium being somehow different from important helium is actually the standard line of the balloon manufacturers. But it makes no scientific sense, so don't listen to it.

      Except that medical grade helium and the crap they fill party balloons with are two different things.

      No, they're the same thing subjected to different degrees of refinement. Everything from balloon helium to the highest-grade purified lab helium come from the same limited sources.

      The volume of the Red Bull Stratos balloon is close to a cubic kilometre. Factoring in the practice jumps and aborted launches, I'd estimate that this project could easily be accounting for over 3% of US helium consumption this year.

      I think it's perfectly reasonable to ask why hydrogen is not a viable alternative. There are probably some good, valid answers to that question, but I don't think that yours is one of them. And we do need a longer, louder discussion of how helium usage should be prioritized: it's neither renewable nor (in many applications) substitutable.

    5. Re:Hydrogen? by Xylantiel · · Score: 5, Informative

      My impression from the previous discussion on this was that helium shortage is a fictional crisis. Medical usages don't do helium recovery, which is where most of the loss occurs. Also the main source of helium - as a by-product of natural gas extraction - just vents most of it because its not worth capturing it. So complaining about "misuse" is nonsense. If one is really worried about a helium shortage one should be pushing for recovery in its biggest usage context and stockpiling. Neither of these are being discussed, so apparently this isn't actually serious.

      History and the modern world are fraught with examples of people wasting resources without adequate planning for the future. Deferring to market-think doesn't make that problem go away. Overconfidence in the market is what causes or exacerbates a high percentage of our problems.

      Even if it WERE true that the market would probably respond to a helium shortage by supplying additional quantities, that doesn't change the fact that one asshole, who wants glory badly enough and who has enough power and resources to make people assist him in his goal, can use much more of a resource than any person has a right to, given the current state of affairs and supply of that resource.
