Blame it on the wind. Again.

Extreme athlete Felix Baumgartner has postponed his second attempt at making a supersonic skydive over New Mexico due to high winds. What’s a supersonic skydive? Good question. It’s a free-fall jump toward Earth from 120,000 feet at supersonic speeds. The feat would make him the first human to break the sound barrier without the propulsion, or protection, of a vehicle.

Sky diver Felix Baumgartner free-falls toward New Mexico during test dive.

Red Bull Stratos, the sponsors of the mission to the edge of space, say that “Baumgartner hopes to help improve our scientific understanding of the stratosphere and how the body copes with the extreme conditions so high above the Earth’s surface.”

Baumgartner’s team estimates the Austrian sky diver and helicopter pilot will reach Mach 1.2 — roughly 690 miles an hour — and free-fall for five and a half minutes before opening a parachute at 5,000 feet to float him to the ground.

The 55-story, ultra-thin helium balloon that is to carry him into the stratosphere is so delicate that it can only take off if winds are 2 mph or below on the ground. The wind on Tuesday got up to 25 mph near the airport in Roswell, N.M., hence the postponement.

Since we didn’t get to see the live footage of Baumgartner performing his death-defying stunt yet, let’s just all watch this Wind Tunnel Acrobatics video from Red Bull to tide us over:
