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)

ESA is pleased to announce the release of several new features as part of the ESA On-The-Fly data processing and dissemination service providing data from the Envisat ASAR and ERS-1/2 SAR mission archives.
29 October 2018
Due to a planned software maintenance on Tuesday 30 October 2018, the ERS and Envisat (A)SAR On The Fly (OTF) dissemination service will be unavailable from 09:00 to 12:00 CET.
Furthermore, the maintenance activities may impact the OTF data search on the same platform (ERS and Envisat) from 13:00 to 15:00 CET.
27 August 2018
Due to a scheduled maintenance, access to the ESAR OADS-OTF instance providing access to the ERS and Envisat (A)SAR data will be unavailable for 3 hours, on Tuesday 28 August 2018, starting from 10:00 CEST.

Using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster.

Over two decades of observations by five radar satellites show the acceleration of ice loss of 30 glaciers in Western Palmer Land in the southwest Antarctic Peninsula.

Five satellites spanning two decades have revealed variations in the timing and pace of glacial retreat in West Antarctica. Some glaciers' thinning spreads up to three times faster than on neighbouring tributaries, and was offset by decades.
Since the launch of the first Earth-observing satellites in the 1970s, numerous missions from international space organisations have taken to the sky. Today, decades of data are helping scientists to build a better picture of changes to our planet.
