ROSWELL, N.M. —
Baumgartner spent Monday at his hotel, mentally preparing for the dangerous feat with his parents, girlfriend and a few close friends, his team said. He had a light dinner of salmon and a salad, then had a massage. He spent Tuesday morning resting in an Airstream trailer near the launch site.
Among the risks: Any contact with the capsule on his exit could tear the pressurized suit. A rip could expose him to a lack of oxygen and temperatures as low as 70 degrees below zero. It could cause potentially lethal bubbles to form in his bodily fluids, a condition known as "boiling blood."
He could also spin out of control, causing other risky problems.
The energy drink maker Red Bull, which is sponsoring the feat, has been promoting a live Internet stream of the event at http://www.redbullstratos.com/live from nearly 30 cameras on the capsule, the ground and a helicopter. But organizers said there will be a 20-second delay in their broadcast of footage in case of a tragic accident.
Despite the dangers and questionable wind forecast, high performance director Andy Walshe said the team was excited, not nervous. Baumgartner has made two practice jumps, one from 15 miles in March and another from 18 miles in July.
"With these big moments, you get a kind of sense that the energy changes," he said Monday. "It really is just kind of a heightened energy. It keeps you on your toes. It's not nervousness, it's excitement."
During the ascent, Walshe said, the team will have views from a number of cameras, including one focused directly on Baumgartner's face. Additionally, they will have data from life support and other systems that show things like whether he is getting enough oxygen.
The team also expects constant communication with Baumgartner, although former Air Force Capt. Joe Kittinger, whose 1960 free-fall record from 19.5 miles Baumgartner hopes to break, is the only member of mission control who will be allowed to talk to him.
