Understanding the Universe
Take a tour of the universe, galaxies, stars and planets. Find out how far a light year is, or find out about other stargazers at this site. If you have an assignment about space this is a great place to start.

International Space Station Tour
The International Space Station (ISS) will be a little “city in space” orbiting 250 miles above the Earth. About the size of two football fields, the space station will be a place where people from around the world can live and study in space over long periods of time. Learn all about the Station, how it works and what goes on there at this site.

Pictures of Earth From Space
Every time we send a person into orbit they take pictures of our Earth from space. The NASA Space Shuttle Earth Observations Photography database has over 375,000 images and they are putting selected photos on the web. See how the earth looks from space, and maybe if you are lucky you will see your neighborhood!
