Daring Austrian base-jumper and skydiver Felix Baumgartner is aiming to break a record that has stood for almost 52 years. In fact he is aiming to break four long established records, starting with world's highest manned balloon flight (120,000 feet or 36,576 meters) highest skydive (currently 102,000 feet ) and the longest freefall, which may well see him break the sound barrier as he plummets for nearly 23 miles (37 km) towards Earth. Last week Baumgartner jumped from 71,581 feet in the first manned flight test by the Red Bull Stratos project, but to reach its ultimate goal the team must beat Joe Kittinger's record for the highest freefall set in August, 1960.

A record that's tough to beat

Kittinger is amazing. He is not only an advisor to the Red Bull team, but is a decorated military pilot as well as the first person to cross the Atlantic solo in a gas balloon. His career includes three combat tours of Vietnam, before he was shot down and spent 11 months as a POW, eventually returning to the USA and retiring as a colonel in the Air Force in 1978. He is still an active pilot, but best remembered for his part in the research into high altitude bale-outs.

Leaping from his open gondola at 76,400 feet (23,300 m) on November 16, 1959, Kittinger's very first high altitude jump nearly ended in disaster as he lost consciousness and went into a flat spin that was calculated to have exerted 22 times the force of gravity on his extremities. Fortunately his parachute opened automatically and a year later, he made his final jump from an altitude of 102,800 feet (31,300 m), reaching a speed of 614 mph (988 km/h). During this jump his pressurized right hand glove failed and in the rarefied atmosphere his hand swelled to about double normal size, but he completed the jump to set records for the highest balloon ascent, highest parachute jump, longest drogue-fall, and fastest speed by a human being through the atmosphere.

Col. Joe Kittinger's leap of faith

Baumgartner's 71,581 feet test jump

Fast forward 52 years, and the Red Bull Stratos team has just spent five years developing its state-of-the-art, pressurized life-support capsule and space suit, intent on breaking Kittinger's records. Weighing 2,900 pounds (1,315 kilograms) 11 feet (3.4 m) high by 8 feet (2.4 m) wide, the capsule hangs approximately 150 feet (46 m) below the helium-filled balloon which will take it to the edge of space. When Baumgartner jumps, the capsule releases the balloon and returns to Earth via its own parachute. As he leaves the safety of the capsule, Baumgartner relies on his special space suit to protect him from the minus 70 degree F outside temperature.

The Red Bull Stratos team's first manned test flight took place on March 15 over the New Mexico desert. During the jump from 71,580 feet, Baumgartner hit speeds of almost 365 miles per hour and spent 3 minutes and 33 seconds in freefall before his chute opened at 7,890 feet.

The jump went "exactly as planned" although combating the extreme temperatures remains a challenge. "I could hardly move my hands," said Baumgartner. "We're going to have to do some work on that aspect."

Although just a stepping stone towards the 23 mile main event, this successful test means that Baumgartner joins Kittinger and Russia’s Eugene Andreev as only the third person to leap from that altitude and survive.

Another test from the altitude of 90,000 feet is planned before Baumgartner and the Stratos shoot for the record later this year ... and there will be one man with his fingers firmly crossed.

That is one of the few things I REALLY want to do....

Absolutely.

(5 miles of brown paper, 100 gallons of paper glue, 10 miles of string...... etc.)

I may be wrong, but I think that something known as "terminal velocity" will prevent him from getting anywhere near the sound barrier.

In normal atmospheric pressure the max speed a skydiver can reach is only about 130mph. But way up at that altitude where the air is thinner he could reach much more than that. Also when his body does break the sound barrier it will be less stress on him, again due to air density.

Speed of sound in space = 0 m/s

Speed of Sound at 102000 ft (31090m) = 327 m/s

Speed of Sound at sea level = 343 m/s

(Woolfram alpha)

Um 100k ft is not even half way to space...

Still plenty of air resistance....

Maybe he can get to 300 miles per hour (133 m/s)

Still a long way to Speed of sound....

Like to hear the boom...

Also, Probably the sonic buffet would vibrate a human body to pieces, and if not, merely kill the person...

We all need adventurers to do the things we can't afford to do.

@MD The article states that Kittinger reached 614mph in his jump from 102,800ft

Robt

According to this article, he achieved 690mph shortly after jumping.

http://www.nytimes.com/2010/03/16/science/16tier.html?_r=1&src=me&ref=general

There was a program on television (don't remember which) that estimated he topped out at around 800mph.

Why, with 26 pictures attached to this article, is there not a single one of him actually jumping from 71K feet?

What a supreme waste of resources!

It isn't a waste of resources at all if you stop looking at this through the eyes of a commoner. Sure it's an absolute thrill if you were the one to jump and set a new record. But the important thing is to learn the effects and the extent of it to a human being who free falls at such height, with a pressurized suit of course. That knowledge will come to use when astronauts need to make an emergency jump at such heights mid flight or return.

26 images and no video? Is gizmag a newspaper?

I would be sincerely impressed IF they started from the International Space station and came back through the atmosphere riding in a RED CORVETTE during re-entry , pulled the parachute and drove away , just like in the 1981 animated movie HEAVY METAL !!!

Did Redbull fund all of this? Most likely more tech gone into this as the Apollo missions.....

Looks like Redbull really can give u wings!!

So he's going to take a balloon 36,576 meters up, then freefall nearly 37,000 meters down? Is one of his other world records "most widely dispersed skydiver" by any chance?

@Fretting Freddy the Ferret pressing the Fret: "commoner"???? WTF? Are you some member of the intergalactic elitist society or something?

@ MD,

you might like to check your calculations. To break the sound barrier at 31,300 m i think you will find it is a lot faster that at sea level not slower. The reduced air resistance will result in a much increased speed required to create a sonic boom.

While he will most likely exceed the speed that would be required at sea level to create a sonic boom. His terminal velocity due to air resistance and general lack of aerodynamics will ultimately keep him from going fast enough to create a sonic boom, aside from all the problems associated with his lack of structural rigidity.

I was always in awe of kittinger, he are the coolest nut. As a kid i would imagine the feeling of reentry. I REALLY WOULD LOVE TO DO THIS. RedBull this is some hard stuff well done! Think back to a time when physicians believed that exceeding 30mph would kill a human to actually going almost 800mph! Next we gotta talk free fall from the space station thats how you get space tourism going and even more jobs for the people with the shovels waiting for you on the ground

Suggestion for the hands: a flap of medium thick plastic that can be allowed to lay back along the arms, or be discarded, when no longer needed.

Brian Hall

True, people typically hit terminal velocity at around 120 mph. However, when you are that high in the sky the air is very, very thin so an object would have to push less air out of the way to fall. Theoretically if someone were to fall from the International Space Station he or she would approach mach 5 before entering the thicker atmosphere that would ultimately slow 'em down to the speeds you're thinking of.
