AMSU-A1 is re-installed on MetOp. The photo shows the instrument in the top right position of the Payload Module, and the place for AMSU-A2 – yet to be installed - is easily recognizable by the metal surface without MLI.
MetOp-A was launched on 19 October 2006 from the Baikonur Cosmodrome in Kazakhstan, on a Soyuz ST rocket with a Fregat upper stage.
