There is a lot of interesting scientific information in this video starting at 2 minutes.
Watch live as our Low-Density Supersonic Decelerator takes to the skies over Kauai, Hawaii, in its second flight test. Via cameras aboard the test vehicle, media and public can watch live on NASA TV and http://ustream.tv/NASAJPL2 as the rocket-propelled craft attains velocity four times the speed of sound, inflates and deploys the world’s largest parachute. This technology may someday help land humans on Mars.
