23 mile skydive!

Heard about this when I was at uni (or that he was going to attempt it) and the dangers he faced if he started to spin, with the lack of atmosphere he wouldn't be able to correct it and could end up in serious trouble through that alone.

Would still love to give it a go :)

Been following this with great interest. 23miles up is an awful long way though, especially if things go wrong early on, extremely brave for trying it, must surely be worth it for the 16+ minutes of free-fall. Having done jumps in the army and two HALOs (normally around two mintues of free-fall) they are still the greatest experiences i've ever had, can't begin to imagine how falling for that amount of time would feel like.
 
anyone know if there is an official twitter feed for this?

One I have found seems to be out of data (Oct 2010 with the last tweet saying "The Red Bull Stratos project has been stopped immediately due to a lawsuit".

If you put water in a pressurised environment and let the pressure out you can actually see the water bubble. Our blood is no different, furthermore, if you get the nitrogen bubbles expanding in your blood, you're going to be in a bad state.

Kittinger lost the use of his right hand as a result of exposure. Still managed to open his chute though!

Freefaller, what sort of altitude do you think he would open up the shute at? I think the last one was something like 18,000, 19,000ft, was this a "safe" choice, or do you think you could get away with going further, say around 11,000ft?

Well I don't know the technology they'll use, they could do it like tandem parachutes, and deploy a small "drogue" chute to stabilise the fall and to bright the speed down, and have a multi staged deployment system. Obviously the longer he is in atmosphere the more he'll slow down, however he'll have limited oxygen. Ideally you don't want to be above 18,000ft for too long as you'll go into oxygen starvation fairly quickly with the adrenaline and effort his body will be under. At high altitudes he'll be travelling a lot quicker than his terminal velocity at 15,000 feet for example.

The time I usually deployed was around 2,500-3,000 feet. However that was at around 100-120mph, with thick atmosphere.

The problem is if you're going too fast you'll either rip the material (rare) or ping some of the lines. I doubt he'll use a square chute - but I could be wrong.

I might actually ask on some of my skydiving forums and see if anyone has any further info. He'll have to slow down though to a fairly pedestrian speed, probably around 150-200mph before deploying. At what altitude this happens I couldn't tell you. However he'll want to get to a breathable altitude ASAP and if he deploys too high he might run out of air :(

I think he's got a blog:

http://felixbaumgartner.com/index.php?id=8

Might be something on there. :)


Excellent links there Simulatorman :cool:

As for when - I guess it's when they finish testing. I hope it'll be this year though!
 
Thanks for the info :)

Will check out the blog later.

I certainly hope there is a nice long documentary to go with this when he attempts in, filmed in super HD :)

Sorry I should have been clearer. I know it will be fatal if there was a hole in it, I was more referring to the use of the word "vapourise".

See: http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/970603.html

Actually, I just checked and the article now says:
Felix Baumgartner will jump from a balloon 36.5km (120,000ft) up, where a leak in his pressurised suit could lead to a rapid loss of consciousness.

My understanding that the hand injury was purely down to cold. And you don't get the bends from dropping to vacuum because there isn't enough of a pressure differential. The partial pressure of the nitrogen isn't enough to get it out of solution. The only danger of a suit breach is asphyxia due to oxygen starvation. And cold-related issues. Your body will freeze long before your blood boils. And is it me, or has this jump been "imminent" for years now?

Yeah I remember it being talked about ages ago. Hopefully it's getting closer to the day!

Seems OK in the video. He's waving it about like a spare willy at a willy-waving contest.
