| | | | | | | Introduction
Envisat is the most powerful tool ever created for monitoring the state of our planet and the impact that our activities have on it. Producing enough digital data to fill the hard drives of 500 desktop PCs every day, Envisat views the Earth with unprecedented detail and richness. The truck-sized satellite carries 10 instruments, powered by a 70 m2 solar array generating 6 kW of electricity after 5 years.
Envisat's uniqueness is not only driven by its instruments. The ability to combine data from different sources into highly sophisticated products - often digital images or 'maps' - reveals views of the world that have never before been possible. In addition, its long lifetime, coupled with the legacy of compatible data from ESA’s ERS-1 and 2 satellites, gives scientists the possibility to create four-dimensional pictures showing the evolution of complex environmental phenomena over a 10-year timescale.
