Europe's 'eco-policeman' in space
|
| ||||
Europe's largest and most complex Earth observation satellite, the ENVIronmental SATellite, Envisat, was launched in 2002 by an Ariane 5 into an 800-km polar orbit. This European Space Agency satellite is helping scientists gain a better understanding of the effects of global warming, El Niño, climatic changes and the depletion of the ozone layer, as well as variations in ocean-levels, ice caps, vegetation and the composition of the atmosphere.

Development and construction of the 8,200 kg spacecraft took more than 10 years, and involved almost 100 companies in 14 countries. EADS Astrium sites in the UK, Germany and France all participated in the programme: EADS Astrium UK was the prime contractor for the Polar Platform and two of the major instruments; EADS Astrium Germany held overall responsibility for the instruments, the payload equipment bay and two instruments; and EADS Astrium France supplied the service module and other instruments.
