ESA has been dedicated to observing the Earth from space since the launch of its first meteorological mission, Meteosat, in 1977. The later series of Meteosat satellites plus ERS-1, ERS-2, Envisat and more have provided us with invaluable data about the Earth, its climate and changing environment.
ESA mission controllers manage some of the most sophisticated Earth observation spacecraft ever built. CryoSat-2 and Swarm are in orbit and the mission control infrastructure for several other vital missions is now in development. An additional mission, SMOS, is being operated for ESA by CNES, France's space agency, from Toulouse.
