Austrian skydiver Felix Baumgartner will have to wait a few more days to complete his "Mission to the Edge of Space," in which he will jump from "near-space" over Roswell, N.M. and attempt to exceed the speed of sound as he plummets to Earth.
HuffPost Science will live-blog Baumgartner's jump, with coverage starting at 10:30 a.m. EDT on Sunday, Oct. 14. We'll be streaming video and keeping you up to date on all things Felix.
The Red Bull Stratos balloon launch is slated for local sunrise on Sunday, which is around 8 a.m. EDT. The ascent to 120,000 feet is expected to take nearly three hours, according to the Associated Press. Three hours puts his arrival at peak altitude at about 11 a.m. EDT.
The exact time Baumgartner will jump on live camera is unclear, but the descent should take 15 to 20 minutes, according to CBS News. Within 35 seconds, he will approach 700 mph. For the last 10 minutes of the descent, he will use a parachute.
"I climb out and step off, and within the first 30 seconds I'm going to accelerate so fast that I'm going to break the speed of sound," Baumgartner told CBS News.
If a Sunday launch proves impossible, the window of opportunity will "remain open until the end of play on Monday," according to Red Bull Stratos.
Baumgartner's Red Bull Stratos mission was aborted on Tuesday, when strong winds threatened the ultra-thin, 55-story helium balloon.
"When Art told me we were aborting the mission I thought it was a joke," Baumgartner said during a Wednesday conference. "I thought, there's no way that the conditions are not right. I couldn't tell what was happening with the balloon because I was in the capsule. I want this to happen this year. We've made it so far. There's no turning back. We're here, we've got the helium and we're good to go. Whether that's tomorrow or the first day next week, I don't really care."
Another attempt was set for Thursday, but weather reports nixed that as well.
If the jump is completed successfully, the 43-year-old extreme athlete will become the first person to break the speed of sound in free fall.
