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.

More than 800 scientists from around the world will gather in Montreux, Switzerland, to attend the 2007 Envisat Symposium from 23 to 27 April to present and review results from ESA Earth observation satellites.
Decision-makers, scientists and local authorities require up-to-date environmental information in order to manage natural resources, respond to natural disasters and better understand climate change.

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.

The most authoritative report on climate change to date will be released tomorrow in Paris, France, and is expected to warn of rising global sea levels and temperatures. Earth observation from space plays an invaluable role in helping scientists advance our understanding of climate change and capability to model its evolution.

Due to a problem with the Proba star trackers following the solar storm event in December last year, the satellite is currently unavailable for CHRIS data acquisitions. Measures are being taken to resolve the situation. It is assumed that nominal CHRIS acquisitions will be resumed from February.

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.

A new section of Earthnet Online devoted to the background planning of Envisat ASAR and MERIS instruments is now available. This planning is done in absence of user requests with the aim of building a consistent data archive.

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.
