A film footage from NASA showing the trip of a solid rocket booster, from the moment it separates from the space shuttle, to its landing. Awesome! Enjoy!

A cool video showing the launching of a rocket (NASA probably) in slow motion. Scortching hot! Enjoy!

This cool engine is probably the one with which NASA will reach Mars. The advantage of it compared to current ones, is that it's cheaper, and that you can potentially harvest it from other planets! Awesome engine!

NASA hopes that this new rover concept is the way to go into the future and it will lead towards a new way of exploring harsh environments, hopefully on other planets! Very cool! And here's an actual (smaller) project built by NASA:

Here's a cool and spectacular explosion of an American DELTA rocket which self-destructed at 13 seconds into its flight. It left behind a massive fire blast. Luckily, it was unmanned.

A really cool video from the Transition Region and Coronal Explorer (TRACE). TRACE is a NASA Small Explorer mission to image the solar corona and transition region at high angular and temporal resolution. Whatever that means. All I can say is that these video of the Sun rulz!

This is NASA WorldWind 1.4 and it makes Google Earth look like child's play. It just takes it to a next level. Besides exploring Earth, you can explore the Solar System's planets just like in Google Earth and see the volcanoes, craters and planet rings. It's plain awesome!
