The European Envisat satellite

Launched from Kourou in French Guiana on the night of 28 February 2002, Envisat is the largest Earth Observation spacecraft ever built.

Can you imagine ? It weighs 8.5 tonnes and is 10 m long, about the size of a double decker bus !

ESA satellite Envisat flies in a sun-synchronous polar orbit of about 800-km altitude. The repeat cycle of the reference orbit is 35 days, and for most sensors, being wide swath, it provides a complete coverage of the globe within one to three days.

Where is Envisat now ?

Envisat carries 10 sophisticated instruments to provide continuous observation and monitoring of the Earth's land, atmosphere, oceans and ice caps.
