Envisat (" Environmental Satellite ") is a large Earth-observing satellite which has been inactive since 2012. It is still in orbit and considered space debris. Operated by the European Space Agency (ESA), it was the world's largest civilian Earth observation satellite. [2]
Launched on 1 March 2002 on an Ariane-5 rocket from Europe's spaceport in French Guiana, Envisat was the largest Earth observation spacecraft ever built with 10 instruments aboard and at eight tonnes was the largest civilian Earth observation mission ever launched.
In March 2002, the European Space Agency launched Envisat, an advanced polar-orbiting Earth observation satellite which provided measurements of the atmosphere, ocean, land, and ice. The Envisat satellite had an ambitious and innovative payload that ensured the continuity of the data measurements of the ESA ERS satellites.
2002年3月1日 · Envisat provided continuous observation and monitoring of the Earth's land, atmosphere, oceans and ice caps. Due to its near-Earth polar orbit (782 km mean altitude) and fast cycle time (one orbit in 100 minutes), the mission presented unique challenges for ground communications and data delivery.
Envisat is the most powerful European Earth Observation satellite yet built. It has begun making the most complete set of observations of our planet that any satellite has ever carried out. Envisat monitors: It helps scientists to understand how changes to one, say climate, affect the others.
Envisat was the largest Earth observation spacecraft ever built. The mission delivered thousands of images and a wealth of data used to study the workings of the Earth system, including insights into factors contributing to climate change.
2024年6月7日 · EnviSat was a satellite mission monitoring Earth’s environment. EnviSat application areas included meteorology, climatology, environment, atmospheric chemistry, vegetation, hydrology, land use, and ocean and ice processes.
