Discovery channel is carrying it but winds have delayed launch for several hours.

Discovery channel talk now and only about Ghost ,UFO ,wizards , curses, zombies and all kind of pseudo sciences   

I remember this was the first scientific channel of science investigation ,Space ,Biology animals , Now you can even see your Horoscope 

Wednesday: October 10.

..its still a bit windy up there... ...>>> http://www.bbc.co.uk/news/science-environment-19884699

Paul.

Soo... Has he jumped yet?

Well it's on Discovery right now...

Just watched it live. Not sure what is more of a feat, Herr Baumgartener jumping out at 127,000 feet or..........watching on my laptop, in Germany, in my house, via wifi, the whole thing live   Because my wife is glued to Strictly Come Dancing..............AND then she watches over my shoulder whilst Johnny Ball does his stuff

Matt

PS, well Done Felix

And that was just fart of relief when he got on the ground........I know how bad it is for me after I have spent a couple of hours on an airliner and need to degas........

Press conference about to start

WOW!

preliminary speed, mach 1.24 - 833.9 mph

Now confirmed and way more than they had hoped for.....

65 years ago today... Chuck Yeager officially broke the sound barrier in the Bell X-1.

The sound barrier had been broken several times between 1945-1947.

I reckon that was something we'll remember watching for many years!

With no lateral motion and no air resistance he would fall very quickly.

The force of gravity on the ISS 200 miles above the earth's surface is 90% of that on the surface.

Any object that travels at 17,500 mph will orbit the earth regardless of its altitude.  It could be a foot off the ground and it would still orbit.  You would have a difficult time keeping it on orbit, though, because the air and buildings and trees and mountains would tend to slow it down and you would constantly have to apply force to overcome the resistance.  You don't have that problem in space.

Conversely, any object that travels less than 17,500 mph will be overcome by gravity and fall back to earth.

How do spacecraft re-enter the atmosphere?  They fire braking rockets to slow their lateral motion.  Once their lateral motion is insufficient to overcome gravity they fall.

Edit - I neglected to consider the relative gravity based upon distance from the center of gravity.  Orbital velocity at the earth's surface is 17,650 mph.  In low earth orbit it is 17,450 mph.  Wikipedia

It was an awesome spectacle.

And 8th & 9th.

One question I have that is not answered;
Once in the lower atmosphere he would have been falling at terminal velocity as a normal free fall parachutist, that being around 140mph. Why did he deploy his parachute at around 6000 feet??

If you jump from the Moon to the Earth you will likely travel faster than the speed of light in the first two minutes.

This has happened before when the Apollo 13 astronauts ran out of air and had to hold their breath for the entire trip back from the Moon.

This is why he was able to make the entire trip in a little over four minutes (although it takes light a little over one second to travel from the Moon to the Earth).
