See the world from the space station

Astronauts aboard the International Space Station have used hand-held cameras to take more than 450,000 photographs of Earth as seen from their orbiting outpost about 220 miles up in the skies since November 2000.

The flexibility to look off to the side, change lenses and choose interesting features to photograph are some of the advantages over stationary Earth-observing cameras on satellites, noted Cindy Evans at the NASA Johnson Space Center in Houston where the database of images is maintained.
