European Space Agency launches radar satellite

The biggest civil Earth-observation programme ever conceived has begun with the launch of a radar satellite from French Guiana.

The EU's Sentinel-1a spacecraft will be followed into orbit by a fleet of other satellites in the coming years.

Together, they will return an unprecedented volume of data on the state of the planet.
