Colorful world from the sensors of sattelite

April 1, 2012
European Space Agency has celebrated the anniversary with a gallery of the unforgettable imagery captured by Envisat’s eight sensors.The largest civilian Earth-observing satellite has orbited the planet more than 50,000 times.With ten sophisticated optical and radar sensors, the satellite continuously observes and monitors Earth’s land, atmosphere, oceans and ice caps.

Envisat’s largest instrument is the Advanced Synthetic Aperture Radar, which can be used day or night because it sees through clouds and darkness.This is particularly useful over polar regions, which are prone to long periods of bad weather and extended darkness.

Other instruments include the Radar Altimeter, which measures surface topography to an accuracy of a few centimetres, revealing the changes in sea-surface height over time.
