After two failed attempts due to weather for his space jump, “Fearless” Felix Baumgartner will embark on his third attempt Sunday to break a record in a 23 mile free fall jump from the edge of space, watched by millions on the Red Bull Stratos live stream video.

Baumgartner, 43, plans to make the free-fall jump from the edge of space at 120,000 feet in the air, wearing nothing but a space suit and helmet. If successful, he will break the record of the highest altitude ever jumped by man and break the sound barrier before landing in New Mexico. The mission, called Red Bull Stratos, will be livestreamed by Red Bull at the Mission to the Edge of Space landing page, or embedded below.

Mission control officials said the three hour ascent will begin around 8 a.m. MT Sunday. The live stream is scheduled to begin at the same time.

Over the weekend, mission meteorologist Don Day said the weather forecast was favorable for the jump in Roswell, N.M. Sunday's jump comes after two failed attempts from wind. The Monday and Tuesday jumps were cancelled after officials said winds on the ground cannot exceed three miles per hour.

"I want to break the speed of sound, no matter what it takes," he said in a statement. "As long as we have a spare balloon and more launch days, I'm good."

By coincident, Sunday marks the 65th anniversary of U.S. test pilot Chuck Yeager who was the first man to break the sound barrier aboard an airplane. Baumgartner will do it wearing just a space suit. His space jump will be the world's highest free-fall, surpassing a 52-year-old record set by U.S. Air Force Colonel Joe Kittinger in 1960 at 102,800. Mentored by Kittinger, Baumgartner’s other goal is to become the first person to break the speed of sound without the protection of an aircraft.

Baumgartner will ascend in a giant helium balloon for about two hours before plunging headfirst at speeds over 700 miles per hour in 40 seconds as air provides virtually no resistance. Baumgartner said the jump will take 10 minutes total, as he falls 115,00 feet in less than five minutes and parachutes the final 5,000 feet for another five minutes.

"I practiced this for so many years, and now, we are almost there, so this is my biggest dream," he said.

The only dangers that “Fearless Felix” face revolve around his suit, which if the pressure fails, could cause his lungs to burst and boil his blood due to rapid changes in the atomospheric pressures and temperatures in space. The extreme cold, uncontrolled spins, chute or life-support system failure pose also pose threats to the daredevil's life.

This isn’t “Fearless Felix's” first extreme jump; Baumgartner set the record for the highest B.A.S.E. jump from a building in 1999 at 1,479 feet off the Petronas Twin Towers in Kuala Lumpur, Malaysia, as well as the lowest B.A.S.E. jump the same year off the Christ Statue in Rio de Janeiro, Brasil. Then, in 2003, he became the first to cross the English Channel by skydiving across the waterway. In 2007, Baumgartner jumped into the "Seating of the Spirits" in Oman, the second biggest cave in the world, as well as the world's tallest building, Taipei's 101 Tower, at 1,669.95-feet tall.

"I'm not nuts," Baumgartner told CNN in 2010. "You know, our records are meant to be broken, and I'm a very competitive person. I like the challenge."
