Austrian daredevil Felix Baumgartner has lifted off on his mission to break a series of freefall records.
His giant helium balloon left the ground at Roswell, New Mexico, and is currently at a height of over 50,000ft. When it reaches a little ove 120,000ft (36.5km), Baumgartner is expected to jump out. His fall would result in him breaking the speed of sound. The whole mission should end in 10 minutes after he takes the jump.
No person has ever gone so high in a helium balloon, nor attempted to make such a jump before. You can watch the entire mission live here on the video embedded below.
