As skydiver, pilot and BASE jumper Felix Baumgartner prepares for his record-breaking jump from 36.5 km, you can watch it take place live on YouTube.
Along with the feed, a number of live data points, like his direction of movement, altitude and so on, are available on the YouTube page.
The live feed will show the jump from the large number of cameras tracking the progress.
There are nine cameras attached to the capsule itself, including three cameras shooting at 4K resolution, four times bigger than HD.
The full-pressure suit that will protect Felix from the extreme conditions at that altitude is also fitted with three HD cameras.
The live feed will come from the cameras on the capsule and on the ground.
In order to track one man falling 36 km above, a specialized camera system was devised for the ground dubbed Joint Long-range Aerospace Imaging and Relay (JLAIR). Two of these are used.
The ground units come with a high-speed camera, capable of shooting at 60 fps, one 4K camera capable of 120 fps if shooting in 2K.
There's also a shortwave infrared camera, much better at spotting Felix against the coldness of space in the background.
The optics of the ground devices were initially designed to track Shuttle launches and feature high-zoom lens and telescopes capable of "seeing" at that distance.
UPDATE: The jump has been postoned due to weather and the earlies that the balloon will begin its two and a half hour ascent is 14:30 GMT, one hour from now, if there are no other delays.
UPDATE 2: Well, it's now been moved to 17:30 GMT, four hours from now, with the next update scheduled for two hours from now. So, you know, come back later, unless the spectacle of the sun rising over the Roswell, New Mexico desert is enough to keep you entertained.
UPDATE 3: The launch time has been changed again, but this time the other way around, and the balloon is now scheduled to start rising at 17:00 GMT.
UPDATE 4: It's off, Baumgartner has now left the capsule where he was preparing to launch after difficulties made it impossible to launch today. Along with the wind, a radio communication problem prompted the team to abort the launch.
