This video clip shows some of the amazing footage from Felix Baumgartner’s chest and head cameras during his successful supersonic skydive attempt Sunday. I’m sure you’ve heard most of this by now, but the preliminary numbers are 9 minutes & 3 seconds jump to landing, top speed of 833.9 mph or Mach 1.24, jump height of 128,100 feet, and freefall time of 4 minutes & 20 seconds. He broke all the records previously owned by Col. Joe Kittinger (who was a consultant on the mission and coached Felix through the whole jump) except for one: longest freefall. Presumably this is because he fell so fast. The faster you fall the shorter your freefall time will be. Felix entered a terrifying spin during the first part of the dive, but he managed to regain control and did not have to deploy the emergency stabilization chute, which would have prevented him from breaking speed of sound.
In other science-related news, photographer and videographer Christopher Malin created a surreal new type of timelapse that I’ve yet to see used on space station footage- a stack. Stacking involves blending each frame of the footage into the next, creating a blurred effect with light trails and star trails. Just watch it, it’s kind of a head trip:
A combination of technical problems and gusty winds caused Feliz Baumgartner’s record-breaking 23-mile supersonic skydive attempt to be aborted just as the balloon was being inflated today. They had a good window of calm winds to work with, but weren’t able to get the balloon off before a gust of wind came along and blew parts of the partially inflated balloon onto the ground. This is a dicey situation, because the balloon material is so delicate and folded so meticulously that once it’s been unfolded, it cannot be deflated and used again. As far as I can gather from what was said during live webcast, they only have one backup balloon. Since this is the largest balloon of its type ever made or used, it’s REALLY expensive, so they really have to get it right on the next attempt.
The air at the surface, and for roughly the first 1,000 feet off the ground, must be absolutely still for the launch to happen safely. Even a little bit of crosswind can take the balloon off course, dragging the capsule across the ground or smashing it into anything nearby, just as NASA learned first-hand a few years ago during this failed balloon launch in Australia.
