What is Envisat?
Envisat was ESA's successor to ERS. Envisat was launched in 2002 with 10 instruments aboard and at eight tons is the largest civilian Earth observation mission.
More advanced imaging radar, radar altimeter and temperature-measuring radiometer instruments extend ERS data sets. This was supplemented by new instruments including a medium-resolution spectrometer sensitive to both land features and ocean colour. Envisat also carried two atmospheric sensors monitoring trace gases.
The Envisat mission ended on 08 April 2012, following the unexpected loss of contact with the satellite. (See related news from 09 May 2012)

Satellite readings show that atmospheric methane and carbon dioxide are continuing to increase despite global efforts to reduce emissions.

Antarctica is surrounded by huge ice shelves. New research, using ice velocity data from satellites such as ESA's heritage Envisat, has revealed that there is a critical point where these shelves act as a safety band, holding back the ice that flows towards the sea. If lost, it could be the point of no return.

One of Greenland's glaciers is losing five billion tonnes of ice a year to the ocean, according to researchers. While these new findings may be disturbing, they are reinforced by a concerted effort to map changes in ice sheets with different sensors from space agencies around the world.

A new study using satellite data suggests that Europe's vegetation extracts more carbon from the atmosphere than previously thought.

Lovers of architecture and history can rest easy: the stability of historical buildings can now be monitored in real time by a new technique with its roots in space.
