International partners are looking ahead to the newest member in a series of weather satellites that deliver images to European forecasters: MSG-3 is set for launch this summer. The Meteosat Second Generation (MSG) satellites are designed to improve weather prediction. The first in the series, MSG-1 – also known as Meteosat-8 – was launched in 2002. MSG-2 followed three years later. Both have been successful in continuing the legacy of the operational meteorological satellites that started with Meteosat-1 in 1977.
