But whether Baumgartner can make what he vows will be his final jump depends on the weather. Winds from a cold front already delayed the jump by a day. Even the Albuquerque International Balloon Fiesta, 200 miles to the north, was forced to delay by a day its mass ascension of more than 500 balloons over the weekend. Baumgartner's jump can only be made if winds on the ground are less than 2 mph.
Still, Baumgartner's team remained optimistic about Tuesday.
"From what we are looking at so far, we are on schedule," meteorologist Don Day said at a media briefing Sunday.
Weather permitting, Baumgartner will be lifted into the stratosphere around 7 a.m. MDT by a helium balloon that will stretch 55 stories high. Once he reaches his target altitude, he will open the hatch of his capsule and make a gentle, bunny-style jump. Any contact with the capsule on his exit could break open the pressurized suit that will protect him from temperatures as low as minus 70 and a lack of oxygen. He hopes to reach a speed of 690 mph to break the sound barrier.
Baumgartner, who has made more than 2,500 jumps from planes, helicopters, landmarks and skyscrapers over the past 25 years, promises this jump will be his last.
He says he plans to settle down with his girlfriend and fly helicopters on mountain rescue and firefighting missions in the U.S. and Austria.
