After the launch of MSG-3 in 2012, the fourth and final satellite of the Meteosat Second Generation missions is ready for launch. Like its precursors, the MSG-4 satellite will be launched on top of an Ariane 5 rocket from the Europe’s Spaceport in Kourou, French Guiana. With the other MSG satellites still operational, MSG-4 will be put into ‘in-orbit storage’. It will ultimately bridge the gap between MSG-3 and the first Meteosat Third Generation satellites.
