pdate: Baumgartner's jump has been aborted due to high winds.

Despite a few early setbacks due to the weather Tuesday morning, daredevil Felix Baumgartner is expected to hurl his fragile human body from the bleeding edge of space for the long-awaited Red Bull Stratos Mission today. The 43-year-old Australian will attempt the record-breaking, 23-mile supersonic dive after ascending through the atmosphere in a specially outfitted capsule. The jump is expected to begin around 1:15 p.m. ET. Once Baumgartner jumps, he'll go from zero to 690 mph in 25 seconds, and break the sound barrier. If all goes according to plan, he'll be plummeting 120,000 feet towards Earth at supersonic speeds for a full five and a half minutes before deploying his parachute. "The pressure is huge," said Baumgartner. "We're excellently prepared, but it's never going to be a fun day. I'm risking my life, after all."
