Daredevil Felix Baumgartner survives 17-mile plunge

[Doomsday101]

Next stop: the edge of space.

Daredevil adventurer Felix Baumgartner has successfully jumped from from 96,640 feet (29,455 meters) from a custom balloon -- the last test required before his planned 23-mile freefall from the edge of space can take place.

On that jump, Baumgarther will achieve supersonic speeds.

The test jump, completed Wednesday morning over Roswell, N.M., involved 3:48 minutes of free fall leading up to a 10 minute and 36 seconds decent. A spokesman for the Red Bull Stratos event, as the jump has been branded, could not provide additional details on the 17-mile leap.

"It felt completely different at 90,000 feet," Baumgartner told the AP. "There is no control when you exit the capsule. There is no way to get stable."

Baumgartner's test jump had been tentatively set for Mon., July 23, following a review of nine years of local weather data. But two days of storm clouds led to the two-day delay.

In compliance with U.S. Federal Aviation Administration regulations, the Red Bull Stratos team could not launch the balloon if skies were half overcast or if the horizontal visibility was less than 3 miles.

I bet he was the guy that we could dare him to do anything as a kid and he would do it while we sat back and laughed. :laugh2:

Okay. Why can't I find his methodology for landing safely? Is it a series of chutes that open?

Once he hits the atmosphere during his free fall friction will eventually decelerate his speeds. The deceleration should cause him to end up falling at terminal velocity(120 mph), which is the typical speed for any sky diver.

I read about similar type theorized space dives in Popular Science several years ago:

if the temperature is -70, why would his blood boil? freezing seems to be the intuitive outcome to me.

also, he will be using a drogue chute so technically he wont be in a free fall

The boiling point of liquids diminishes as the pressure is reduced. So, the higher his altitude, the more likely to boil.

At 63,000 ft, the blood begins to boil at 98 F and the higher you go, the lower the temperature.

That is interesting. The boiling point of blood at sea level is 256.2 degrees Fahrenheit. The boiling point of water goes down 1 degree Fahrenheit for every 500 ft increase in altitude, so it should be similar for blood. At 23 miles, that is a 242 degree difference, so the boiling point of blood at that altitude should be 14.2 degrees. The -70 degrees is obviously lower than that, but if it were an instantaneous exposure to the air his normal body temp of 98.6 degrees would be enough to boil his blood. That is what I come up with.

[dexternjack]

I am still trying to grasp the neg 70 in relation to the atmo pressure. I read somewhere -70 was in C but that would put it at -94 F. Also read the -70 was already in F, kind of confusing. I cant find anywhere on the internet that the temperature at 23 miles is anywhere close to those temperatures. Still searching......

[joseephuss]

that neg 70 degrees is in Celcius.

From the article: "With air temperatures of -70 degrees Fahrenheit"

There is a significant decrease in pressure at those altitudes and as pressure decreases so do boiling points. Thus, at extremely high altitudes it takes far less energy from heat to boil one's blood.

Pressure......or lack of, I believe.

Think of a pressure cooker......or reverse actually.

I'm betting they are going to heat the suit.

Can't imagine they are going to just let him suffer through minutes at -70 and hope he pulls through.

It's crazy to think that he'll be slowed down that much. Terminal velocity.

I read that the claim of killing someone with a penny from the top of Empire State is false because the penny won't reach a high enough speed.

Not sure if it is true or not.

Definitely. The article just mentioned that the blood boiling would occur if his skin was exposed just to provide an example of the extreme conditions.

Shoot a bullet from a high powered rifle straight in the air. Let's say it leaves the rifle at the speed of sound. It reaches a stopping point and returns back to Earth, but it doesn't reach the same velocity it had when it left the rifle. It only gets to its terminal velocity. Physics is some crazy stuff.

It's true.

Think about it...let's say rain falls from higher than the Empire State Building. I know it doesn't always, but someday, somewhere, it has. People aren't diving out of the way to avoid rain drops. You hardly feel them, and, according to physics, they'd be falling at the same speed as the penny.

It's called ebullism. Boiling is actually a mixture of heat and atmospheric pressure. As you know, at sea level it requires 212 degrees for water to boil. At around 60-65k feet, your blood would boil at it's normal body temperature of 98.6 Fahrenheit.

Being in a complete vaccum of space would be a very bad thing. Ebullism to you would be like Mike Tyson in his prime.

You've probably heard of the bends that scuba divers deal with. Pretty much the same thing. Their blood basically boils out compressed nitrogen gas as the diver ascends to the surface. If it comes out fast, you get the bends and sometimes die from it. This is why scuba divers ascend slowly.

Is that show cancelled, postponed or what? Last I heard, it was cancelled after the donkey episode but 2 weeks ago was a new episode but don't see any future listings?

Entertaining show, I like it.

LOL. Last I heard, the Donkey episode helped tube the show, but you never know.

Reruns showing thru mid-August for now, is all I know of.

This guy did not fare as well, BTW he lives, it would be morbid to put this up if he didn't.

Good job, camera man.

Make sure you get the entire fall and plenty of time after to get the shot.
