Envisat still going strong after five successful years

01 March 2007

Launched from Kourou in French Guiana on the night of 28 February 2002, ESA's Envisat spacecraft marks its fifth year in space. Having orbited Earth more than 26 000 times, the world's largest and most complex environmental satellite ever launched has travelled a distance of more than 1 000 000 000 kilometres, nearly the equivalent of travelling to Jupiter and back.

ESA Earth Observation Campaigns Data

13 February 2007

During the last 25 years about 50 Earth Observation campaigns have been conducted including ground-based, air-borne, balloon-borne, ship-borne and small satellite experiments. These were initiated in support of future mission development and of validation of missions in orbit. It is now well established that these activities constitute essential elements of Earth Observation missions.

ESA mission controllers react to solar flare

18 December 2006

An energetic storm on the Sun has forced ESA mission controllers to react to anomalies or take action to avoid damage to spacecraft. Several missions, including Integral, Cluster and Envisat, felt the storm's effects, highlighting the need for ESA's ongoing development of space weather forecasting tools.

Climate experts search for answers in the oceans

14 December 2006

By absorbing half of the carbon dioxide emitted into the atmosphere, the oceans have a profound influence on climate. However, their ability to take up this carbon dioxide might be impaired as a result of climate change. To determine their response to global warming, ESA has backed two projects that provide systematic data on key oceanic variables - colour and temperature.
