Smile, Earth! 10 years ago on Mar. 1, the European Space Agency launched an 8 ton satellite called Envisat, armed with high-tech photographic weapontry, radar to see through clouds, as well as instruments to capture ocean color and cloud cover, see infrared and thermal spectrums, and even register surface topography. Envisat has since orbited the earth 50,000 times and captures some of the most gorgeous photos of this spinning ball of mud we lovingly refer to as home. Smile, Earth!
