A helium balloon carried Felix Baumgartner's capsule nearly 24 miles to the edge of space. He then jumped from an altitude of 128,000 feet.
On the way down Baumgartner became the first human to travel faster than the speed of sound without being inside a craft. He reached a top speed of mach 1.24, just under 834 miles an hour. Baumgartner opened his parachute at 5,000 feet to complete the 10-minute jump.
