A composite radar image showing Salt Lake City and the nearby Great Salt Lake in the US state of Utah. The line running across the lake is the Lucin Cutoff railway; the causeway supporting the line divides the lake and prevents the normal mixing of waters. The lower-left portion of the image shows Salt Lake City with marshlands and mudflats separating it from the water. Image credit: European Space Agency
Launched in 2002, the European Space Agency’s Envisat Earth observation satellite is the largest Earth observation spacecraft ever built. Envisat is now retiring after 10 magnificent years – double its planned mission lifetime.
In this wallpaper collection, we feature a very small sample of the formidably large collection of images captured by the eight-ton satellite – equipped with 10 sophisticated optical and radar instruments – in more than 50 000 orbits, together with images from ESA’s so-called “Third Party” missions. Envisat has contributed immeasurably to our knowledge of Earth, its weather patterns, oceans, atmosphere, environmental challenges and myriad other processes.
