Landsat 7
This is an engineering exact replica of Landsat 7 which has been providing images of earth since April 15, 1999. It is in a pole to pole orbit which covers photographic strips covering all the planet's land every 16 days. The images, in many different wavelengths, are used to measure land use and change. They look at everything from urban growth to forest fires and volcanos.
