Skydiving attempt - (1 Viewer)

That is freakin sweet. So is 130k feet actually in space? Or is it just inside Earth's atmosphere/ozone layer/whatever?

130k feet = 24.62 miles = 39.4 kmNot even close to space.

the definition of where "space" begins is somewhat arbitrary. the variation in the earth's atmosphere is continuous.. there is no obvious point at which you say "this is space."

generally, i believe, altitudes above 100 km (62 miles) are considered to be "space."

Wow no kidding. Thanks for that info.

About 90% of the ozone in our atmosphere is contained in the stratosphere, the region from about 10 to 50 km (32,000 to 164,000 feet) above Earth's surface. Ten percent of the ozone is contained in the troposphere, the lowest part of our atmosphere where all of our weather takes place. Ozone concentrations are greatest between about 15 and 40 km, where they range from about 2 to 8 parts per million.

It depends on what you're modeling. Drag becomes significantly less of a factor much lower than 100k, but 100k is a nice number.

I think he meant "outer space".

That's what I'm talking about.FYI: "The Federation Aeronautique Internationale has established the Kármán line at an altitude of 100 km (62 miles) as a working definition for the boundary between atmosphere and space."

 
I liked this too from Wikipedia:

* Sea level - 100 kPa (1 atm; 1 bar; 760 mm Hg; 14.5 lbf/in²) of atmospheric pressure

* 4.6 km (15,000 ft) - FAA requires supplemental oxygen for aircraft pilots and passengers.

* 5.0 km (16,000 ft) - 50 kPa of atmospheric pressure

* 5.3 km (17,400 ft) - Half of the Earth's atmosphere is below this altitude.

* 8.8 km (29,035 ft) - Summit of Mount Everest, the highest mountain on Earth

* 16 km (52,500 ft) - Pressurized cabin or pressure suit required.

* 18 km (59,000 ft) - Boundary between troposphere and stratosphere

* 20 km (65,600 ft) - Water at room temperature boils without a pressurized container. (The popular notion that bodily fluids would start to boil at this point is false because the body generates enough internal pressure to prevent it.)

* 24 km (78,700 ft) - Regular aircraft pressurization systems no longer function.

* 24.7 km - Altitude record for manned balloon flight

* 32 km (105,000 ft) - Turbojets no longer function.

* 45 km (148,000 ft) - Ramjets no longer function.

* 50 km (164,000 ft) - Boundary between stratosphere and mesosphere

* 80 km (262,000 ft) - Boundary between mesosphere and thermosphere

* 100 km (328,084 ft) - Kármán line, defining the limit of outer space according to the Fédération Aéronautique Internationale. Aerodynamic surfaces no longer function due to lack of atmospheric pressure.

* 120 km (400,000 ft) - First noticeable atmospheric effects during reentry from orbit

* 200 km - Lowest possible orbit with short-term stability (stable for a few days)

* 350 km - Lowest possible orbit with long-term stability (stable for many years)

* 690 km - Boundary between thermosphere and exosphere

 
Old dude's got balls... :eek: But gravity's doing all the work.

If I fell for 24 miles, I'd pee my pants, drink 8 oz. of water to rehydrate, wait for my body to absorb the H2O and still have enough time to pee my pants a 2nd time before my chute opens.

:scared:

pressurized hot-air balloon cabin?WTF?

 
the terminal velocity of a skydiver in a normal free-fall position with a closed parachute is about 195 km/h (120 Mph). It would take about 5.5 seconds to reach that speed. This speed increases to about 320 km/h (200 Mph) if the skydiver pulls in his limbs—see also freeflying.

This guys going to have at least around 10 minutes to fall. Damn.

They're saying he expects to break the sound barrier. I guess that will happen early, in the thin air.

sound barrier = 343 m/s at STP. That's >1200 km/hr. I suppose terminal velocity might be higher up there and/or the speed of sound is drastically reduced (I'd imagine both are true)

looks like around 315 m/s, or 1134 km/h. Wow.
 
Saw a thing on the Science Channel about a test-pilot guy that skydived from 100,000 feet back in the 60's...he broke the sound barrier.

Similar debates have been going on for centuries concerning the exact point at which the ###### begins. For me, this is important, because I was either devirginized at 15 or 4. I wait while scientists confirm.

This may explain a lot.

In one of those weird moments in life that make you shake your head and say WTF, I'm sitting here reading this thread and then I start flipping through channels to find something to watch....and low and behold there is a special on about Kittinger and his original jump from over 100,000kms. :eek:

:goodposting: I knew I wasn't crazy.

The guy broke the friggin' sound barrier. From a balloon!

I think you have your units messed up there bro. I'm pretty sure that 100,000 km is far above the level where he would return to earth safely. In fact, that's 1/4th the distance to the moon (approx. 400,000 km).I think you mean 100,000 feet, which is still gnarly.

It happened after the balloon was inflated on the ground at the airport in North Battleford, Saskatchewan. The balloon drifted away into the sky without the capsule.

Fournier appeared disappointed as left the capsule and walked to the hanger. He was hugged by members of his entourage.

The balloon was reported to have cost at least US$200,000 and Fournier was said to have already exhausted his finances.

Bummer.
