They're looking to break the speed of sound by skydiving from space. D: I love Red Bull, they do such cool projects.
More pictures and info here.

that looks epic, can't wait until they do it
I don't think a person can break the speed of sound naturally. Terminal velocity for a person is like 500 mph slower than the speed of sound isn't it?
I assume it's possible because of the lack of air resistance when jumping from that height.
220mph?KEN-JENNINGS wrote:

sounds a bit low

Based on wind resistance, for example, the terminal velocity of a skydiver in a free-fall position with a semi-closed parachute is about 195 km/h (120 mph or 55 m/s).[2] This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on. Higher speeds can be attained if the skydiver pulls in his or her limbs (see also freeflying). In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),[2] which is also the terminal velocity of the peregrine falcon diving down on its prey.[3] And the same terminal velocity is reached for a typical 150 grain bullet travelling in the downward vertical direction — when it is returning to earth having been fired upwards, or perhaps just dropped from a tower — according to a 1920 U.S. Army Ordinance study.[4]
Competition speed skydivers fly in the head down position reaching even higher speeds. The current world record is 614 mph (988 km/h) by Joseph Kittinger, set at high altitude where the lesser density of the atmosphere decreased drag.[2]
An object falling toward the surface of the Earth will fall 9.81 meters (or 32.18 feet) per second faster every second (an acceleration of 9.81 m/s² or 32.18 ft/s²). The reason an object reaches a terminal velocity is that the drag force resisting motion is approximately proportional to the square of its speed. At low speeds, the drag is much less than the gravitational force and so the object accelerates. As it accelerates, the drag increases, until it equals the weight. Drag also depends on the projected area. This is why things with a large projected area, such as parachutes, have a lower terminal velocity than small objects such as bullets.
wtf, how is a parachute going to stop you from going that fast. When that parachute hits its going to snap his body apart
15 more years! 15 more years!
he will probably make him self less aerodynamic first to slow down, than maybe deploy a small parachute to slow down even more, and than open his main parachute.Mitch wrote:

I doubt he will brake the sound barrier. I guess he will be jumping from a similar height as the current record holder but he needs to go 250 km/h faster.

Red bull is a pretty crazy company, and damn good at marketing.
The product alone is one of the worst values in its category. All the competition came in with drinks twice the size for the same price, or cheaper. Instead of fighting back with products, they took it to marketing and associate their brand with every extreme sport possible and amazingly it seems to be working for them.

So did I victor...
EDIT: lol just noticed we googled the same image :3
Changed mine for 20th century epicness...

Your thoughts, insights, and musings on this matter intrigue me

I believe terminal velocity for a person is well below the sound barrier even at higher altitudes where the air is thinner?cl4u53w1t2 wrote:

Haha, and he's Austrian! But he's not jumping from space - he'll still be within Earth's atmosphere.
XS > Redbull, tbh.
but thats why they made the suit, it decreases air resistance, or am I wrong here?FloppY_ wrote:

@People who seem to be doubting this: I'm quite sure the guys at RedBull have put a lot of thought into this, so that it theoretically will be possible. There's no point skydiving from space if you're not going to make a decent effort at the record. Also note that the previous guy to do it did it spread eagle, so by jumping head first it will probably be enough to make up the difference. In lower altitudes (12,000ft - a 10th of what he's jumping from) the difference between the two positions accounts for about 80MPH.
Depends on the altitude, way up there the air is thin enough that you can get pretty high speeds. For example the RV's coming back from the moon mission slowed down gradually as the air got thicker.KEN-JENNINGS wrote:

He'll probably have to wear the equivalent of a space suit and stuff.
When an Astronaut does an EVA technically he's travelling way faster than the speed of sound relative to the Earth. So it wouldn't be the first time someone is like, outside on their own, going faster than the speed of sound, if you get me.
But it probably would be the first time someone is, outside, whilst breaking through the barrier under their own propulsion. It is possible, he'll defo need a specialised suit. Falling from space it's more than easily possible to break the sound barrier just depending on gravity. Depends on the height really.

I'm with ghetto on this one: I think the guys at Red Bull with the PHDs and Master degrees and all that jazz know better than a few gamer nerds on what is achievable and what is not.
It's basically about mastering the art of creating a space-suit that also works as a re-entry vehicle without killing the person inside.
