Minimize Envisat

Envisat (2002 - 2012) was launched in 2002 with 10 instruments aboard and at eight tons was the largest civilian Earth observation mission ever operated. 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 three atmospheric sensors monitoring trace gases. The Envisat mission ended on 08 April 2012, following the unexpected loss of contact with the satellite.
