Earlier today Felix Baumgartner survived his sky dive from more than 24 miles above the Earth’s surface. In doing so he became the first person to break the sound barrier without an engine. The Red Bull Stratos website is packed with information about the science and technology involved in the jump. Two videos from the site that might be of interest to science teachers and their students are Speed of Sound Explained and this video about the balloon that lifted Baumgartner more than 128,000 feet above sea level.

I recommend visiting Larry Ferlazzo’s blog for a list of graphics and images outside of the Red Bull website. I particularly like this infographic that Larry listed.
