The International Space Station is more than just an orbiting home and laboratory for its crew members. Floating more than 200 miles above our planet, it also serves as the ultimate manned Earth observation outpost. Using professional digital cameras with an ample array of lenses, astronauts capture images of the planet’s dynamic atmosphere and changing landscape from this unique vantage point. More than 700,000 photographs have been taken to date. The collection includes shots of glowing auroras and brightly lit cities from around the globe. Such images compliment observations made by NASA's fleet of Earth science satellites. Watch the video to see a compilation of time-lapse views of Earth taken by astronauts aboard the space station.
