The last weather satellite in Europe’s highly successful Meteosat Second Generation series lifted off on an Ariane 5 launcher at 21:42 GMT (23:42 CEST) on 15 July from Europe’s Spaceport in Kourou, French Guiana.

The two-satellite MSG system provides up-to-date weather coverage over Europe and Africa every 15 minutes and ‘rapid scan’ imagery over Europe every five minutes.
Some 40 minutes after launch, MSG-4 separated from Ariane 5 into the planned transfer orbit. Over the next 10 days, the satellite’s propulsion system will raise it into a geostationary orbit some 36 000 km above the equator, where its speed matches Earth’s rotation.
Once these initial efforts are completed by ESA’s European Space Operations Centre in Darmstadt, Germany, MSG-4 will be handed over to the satellite’s owner, the European Organisation for the Exploitation of Meteorological Satellites – Eumetsat – to commission the payload.
ESA’s Director General, Johann-Dietrich Woerner, commented, “After just two weeks as the new DG for ESA, it has been a pleasure not only to witness the launch of this satellite, but also observe the continued cooperation between ESA and Eumetsat.
“Tonight’s launch allows the continuation of high-quality observations of weather from space, including rapid detection and warning of extreme weather situations – imperative for keeping European citizens safe.”
After commissioning, MSG-4 will become Meteosat-11 and be ‘stored’ until it replaces one of its predecessors. It will then ensure the continuity of the data until the first Meteosat Third Generation (MTG) satellites enter service, expected in 2019 and 2021.
