MetOp is a series of three new polar-orbiting satellites to be launched sequentially starting in 2006. The series forms the space segment of the Eumetsat Polar System and represents the European contribution to a new cooperation with the USA marking a new era in global weather monitoring and forecasting.

MetOp-A was launched on 19 October 2006 from the Baikonur Cosmodrome in Kazakhstan, on a Soyuz ST rocket with a Fregat upper stage. MetOp-B is scheduled to launch in 2012.
