It gave me goosebumps when the guy finally jumped. My son kept asking me if he was going to die.

So I admit I am not a space/science buff but...why was there gravity when he was in space??? Was he not high enough?

Gravity is everywhere there is mass. (mass being a planet for example). Gravity exists regardless of an atmosphere.

The earths atmosphere is made up of lots of elements, nitrogen, oxygen, helium, etc. Gravity holds those gases around our planet. Space is simply the point at which our atmosphere ceases to exist. It is not a clearly defined line but the atmosphere slowly gets less and less livable the higher up you go. But gravity exists regardless of that atmosphere line.

You already know that gravity exists in empty space. That is why our earth revolves around the Sun. There is nothing but space (well, let's say there is no atmosphere) between the Sun and the Earth yet gravity keeps the earth revolving around the Sun.

So, when this skydiver went that high up, he simply went past the livable atmosphere, but of course gravity still exists up there, and thus he fell when he jumped off the capsule.

Too much for me to wrap my head around five beers in LOL.

I'll ask another potentially stupid question if I may...

Why didn't he "burn up" as he entered the atmosphere?

Great questions! Not stupid at all. I'm not an expert, so my answers could be wrong. I've just read a lot about astronomy and crap like that. I'll try to answer.

Why didn't he burn up? Speed is the critical factor. His speed at the beginning of his jump (relative to the atmosphere around him) was zero. Once he jumps he immediately starts to gain speed. (accelerate) However, all objects have what's called a terminal velocity: the speed at which your own drag causes your acceleration to stop. Drag simply means his body was hitting all those particles in the atmosphere, and that creates drag, and drag slows down your acceleration eventually until you stop accelerating.

If he'd had been shot out of a cannon at 10,000 miles per hour before he hit the atmosphere, yeah, then he'd be burnt to a crisp. But he wasn't going that fast. That is why the space shuttle burnt up on re-entry years ago, it was going so freaking fast BEFORE it entered the atmosphere, it was impossible for drag to slow it down without the shuttle ripping apart.

Of course, there was some risk in it. He was the first human being to go faster than the speed of sound without any ship, car, shuttle, craft of any kind. Just a body suit. Some people thought that was risky, no one knew what was going to happen when his body hit the speed of sound. But he survived it. Pretty amazing!

Ahh....got it...thanks...interesting stuff. I just wish Red Bull or whoever marketed this thing better...I would have liked to research it before hand!

Bet this guy will never enjoy skydiving or base jumping again

Just to put this in perspective...

He jumped from 24 miles.

The International Space Station orbits at 230 miles.

GPS Satellites orbit at about 12,000 miles.

TV and Radio Satellites orbit at 22,236 miles.

So you are going to be that guy, huh? Are you also the type of person who would scoff at how fast Usain Bolt runs because he isn't as fast as a gazelle or a cheetah?

It was near space. He was never weightless nor was the vehicle ever in space despite news reports claiming so.

While watching the whole guy in his capsule, I kept having this song going through my head:

I've been following this jump since April or May. I watched every minute of the coverage on YouTube including the aborted attempts earlier in the week. My wife made fun of me for following it so closely and even yesterday as I was watching before the actual jump. However after the jump, she thanked me for making her watch it.
It's hard to quantify it, but I think what I liked about the mission so much was that Felix had Kittinger's respect so much that Joe wanted to be apart of this mission. That was the coolest part of the jump to me.
