Virgin America's Captain Christopher Owens gives us a tour of their high-tech flight simulator used for pilot training and reveals just why simulation is an effective learning tool.

Take to the skies on board the zeppelin Eureka with pilot Andrea Deyling of Airship Ventures and get a crash-free course in lighter-than-air flight: What’s the difference between an airship, a blimp, and a zeppelin? How do they stay aloft? How high and how fast can they fly? Airship Ventures operates the only commercial passenger airship operation in the United States.

This machinima, a movie made entirely within Second Life (a 3-D virtual world), shows a simulation of the impact of a meteor on the surface of Mars.

An introduction to making a simple rocket and a rocket launcher, including a demonstration of how the finished model will fly.

A step-by-step demonstration of how to make a simple rocket, including a discussion of materials needed and where to get them.

A step-by-step demonstration of how to make a launcher to send your rocket sky-high, including a discussion of materials needed and where to get them.

The science behind the rocket and rocket launcher in the Bottle Blast Off activity, with troubleshooting tips for how to fine-tune the nose and fins of the rocket for better flight. Also includes tips on how to take the activity further by making a simple inclinometer to measure how far your rocket flies.

Aeolian Landscape is an exhibit in which a miniature wind-swept desert landscape is recreated by an electric fan and finely ground sand that mimics the process of wind picking up and depositing small particles. Visitors can change the direction of the fan, influencing the shape of the dunes.

An clip of the Aeolian Landscape exhibit by artist Ned Kahn. Blowing air sculpts sand into an ever-changing landscape.

Mike Wiltberger, magnetospheric physicist at the National Center for Atmospheric Research, narrates this artist’s rendering of a coronal mass ejecting from the sun and then impacting the earth’s magnetic field. Animation produced by the National Aeronautics and Space Administration.
