I am tuning in tomorrow to see him go for the Speed of Sound!

Skydiving from 23 miles above Earth is certainly not for the faint of heart. That’s what 43-year-old Austrian daredevil Felix Baumgartner will set out to accomplish this Tuesday morning (Oct. 9).

With only a pressurized spacesuit and a parachute, Baumgartner hopes to become the first person to break the speed of sound during free fall. If successful (i.e. survives), he will set a new record for the highest and fastest human free fall in history.

I'll watch out for debris and human parts.

Crazy crazy crazy.

Here's the record he'll be breaking.

Can't wait to see this one.

650mph apparently. I have no idea how he will survive this. Starting at 2% pressure to 100% so quickly I'd have thought his lungs would be ****ed Also the temperature. Going from -50 to 20+ is going to be one costly body bag to land in

Pressure suit.

[ProomoSam]

Pressure suit.

No doubt, but it's gotta be some crazily good pressure suit to react so quickly to change of pressure, no?

[CaseyFan]

That's why he'll be wearing a spacesuit, anyway I still wouldn't want to be him.

/Off to check if there are any odds on Betfair.

Much faster than an airlock?

45 minutes left.

This guy has even bigger balls than Chuck Norris

Blasphemy.

Mmmm, it'd be close... but Chuck would win.

Rapid increases in pressure aren't really a concern. It's something I deal with all the time while scuba diving. The pressure changes this guy is going through is nothing compared to the changes a diver goes through. I've personally gone from 1ATA to 4ATA in less than 5 minutes on a couple of dives, and as long as you can equalize your air pockets (inner ear, sinuses, etc) it's no big deal. With a pressure suit, this jumper may experience a change of .5ATA.

The real concerns are from rapid "decreases" in pressure, and when pressures are so great, you have to worry about Nitrogen Narcosis or Oxygen Toxicity.

I don't believe it, a fact on a forum from someone who does it as his job. Blimey the internet isn't wasted... even I've learned something today.

Ok, so pressure won't be a problem, however would you not feel the temp change even in a suite?

I doubt it, otherwise the suit wouldn't be doing it's job!

Man I'm liking the fact you corrected my spelling and didn't have to say a word... hahaha...

I'm not quite as pedantic as the others, we're only human

Actually thinking about it, the cooling system in the suit has to be able to react fairly fast, so there maybe a few uncomfortable seconds, but it shouldn't be too bad, maybe 10'C either way?

Yeah that's what I'm thinking, traveling at that speed... there will be very quick temp changes, not like say a space suit (got it now!!!) that would normally just warm you up say... not sure... either way, it'd have to be reactive and do it quick I'd have thought...

That was my main concern earlier on in the thread. There is already a 75C temperature difference between surface and 20 miles up in the air. Then the suit has to withstand 690MpH of friction and a not so substantial radiation from being in space.
