What happens to a dive deferred? It explodes with anticipation, of course, at least in the case of “Fearless” Felix Baumgartner’s postponed attempt to jump 23 miles from space and break the sound barrier. He’s been training for this day for five years, but dangerously high winds delayed Baumgartner’s most recent high-flying attempt on Tuesday morning. The edge-of-the-world jump was already moved from Monday to Tuesday, and this latest delay only extends the anticipation for Baumgartner and his team–and for all of us wide-eyed onlookers at the edge of our earthbound seats.

Baumgartner has many safety precautions in place for his jump, including the latest technologically advanced gear built by specialized engineers. When he leaps from a balloon filled with helium floating at the cusp of the earth’s atmosphere, Baumgartner will don a pressurized space suit that traces its origins to the orange suits astronauts wear at launch and will protect his blood from boiling at such great heights. Reaching 120,000 feet above Roswell, New Mexico will take time, two and a half hours to reach the planned height, while the free fall will only take about 10 minutes before Baumgartner opens his parachute.

While a dangerous plan even with so many precautions and so much preparation, Fearless Felix is no novice to daredevilish dives. In July he succeeded in a 18.3 mile skydive from the Red Bull Stratos balloon, where he reached a top speed of  536 mph. This time, he’s hoping to move faster than sound moves through air. If successful, Baumgartner will become the only human to travel that fast outside the safe walls of a machine.

A member of Baumgartner’s team, Joe Kittinger, holds the previous record for the longest jump from space. In August 1960, Kittinger lept almost 20 miles; in October 2012, he’ll assist his successor through radio communication from the ground below.

Barring any other delays, the attempt has been postponed just a bit longer: until Thursday, October 11. When the mission is finally a go, fans will be able to cheer him on and watch the jump live in high definition here.
