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)

Unexpected issues have been observed in the On-The-Fly (OTF) processing upon downloading Envisat L1 data products from the OTF collections in EOLI-SA; as a result, the L1 product is not generated / downloaded, and marked as unavailable.
The issue is currently being actively investigated and will be solved as soon as possible.
For the last 30 years, the European Space Agency (ESA) has been providing Earth Observation (EO) data, technical information and data analysis tools in support of EO satellite missions. The HEDAVI (HEritage DAta Visualisation) service enables users to discover a wealth of heritage data from ESA's ERS and Envisat missions, as well as from Landsat-5 and Landsat-7, two important heritage Third Party missions at ESA, through ESA's heritage data programme ‘LTDP'.

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.
