Visiting The Sphere
Date: November 7, 2006
The first thing to greet Sphere theater visitors is an illuminated six foot globe hanging in the center of the room. It's a display screen unlike anything else. Images can be displayed fully in the round, affording educators unusual opportunities for presenting talks about planetary science to diverse audiences. As an educational tool it's not only powerful, but also captivating. But the Science On a Sphere environment also affords an extraordinary platform for portraying cinema quality media experiences. In FOOTPRINTS, the first fully produced movie for the Sphere platform, NASA introduces a variety of exciting subjects to national audiences. The film touches on hurricane science, how satellites collect data from space, lunar exploration, Mars exploration, the Earth's cryosphere, gamma ray bursts in deep space, and more.

The Sphere - How It Works?
Date: November 7, 2006
Here's how a Sphere theater works: Four computers each drive a single projector, positioned around the sphere in ninety degree increments. A fifth computer essentially regulates the system. When a source image-a flat map of the earth, for example-gets fed into the main system, the fifth computer essentially cuts up the image into quarters and distributes those quarters to each of the four projector computers.
Played back in properly timed sequence, those images fit back together on the screen, conforming to the shape perfectly.
NOAA developed Science On a Sphere projection technology. NASA developed the technique to put a full motion video on that Sphere.

"Data Analysis and Presentation" - NES Challenge continued
Date: May 12, 2006
"Data Analysis and Presentation”. Marci Delaney, from NASA Goddard Space Flight Center, returns to demonstrate another step needed to complete a project for the NES Challenge. Marci continues discussing the sample project: Can I land my spacecraft in the crater of the Moon? In this episode, Marci explains how to perform a ratio calculation when determining the actual diameter of a crater by using previously collected data. She also demonstrates two methods that can be employed when presenting project data.

Sun For Kids
Date: January 18, 2006
We look at the sun rising every day. It’s bright, it’s big and it warms us up. Our sun happens to be the brightest object in our universe and naturally we are really curious to know more about it. Our sun gives us light, heat and energy. It may seem that energy comes from other sources such as gasoline and electricity but the ultimate source of energy for the Earth is nothing else but the sun. Without the sun life on Earth would not exist. It would be so cold that no living thing would be able to survive and our planet would be completely frozen. In Sun for Kids scientists from NASA and the European Space Agency visit a classroom in Parkland Magnet School in Rockville, MD to talk to the students about the sun. This movie will tell you curious facts about this giant star and will show you fascinating images from the SOHO satellite as well as amazing animations of the largest eruptions in the solar system. Please note: Never look at the sun without proper eye protection!

Aura and Climate Change
Date: December 22, 2005
Aura will quantify and map the variability of ozone and water vapor, important "greenhouse gases" in the upper troposphere, and how aerosols either absorb or reflect radiation, in order to help us understand climate change.

Liquefying Air
Date: November 15, 2005
We're all familiar with the fact that hot air expands and cold air contracts. This video takes that idea to a level beyond what we see in everyday life. We take balloons filled with air and cool them with liquid nitrogen, which is at a temperature of minus 196 Celsius (minus 320 Fahrneheit). The balloons shrink visibly as the air inside them contracts. Some of the air even condenses into liquid air. When we remove the balloons from the liquid nitrogen coolant, they warm back up to room temperature. As they warm up, they expand to the size they were before we cooled them in the first place.

Properties of Matter
Date: November 15, 2005
This video shows how ordinary objects can have some strange properties when we cool them down to cryogenic temperatures. We use liquid nitrogen at a temperature minus 196 Celsius (minus 320 Fahrenheit) to cool bananas and flowers. The bananas become so strong when they freeze that we can use them as hammers. The flowers become so brittle that they shatter when grasped.
