The first of Europe’s next-generation meteorological satellites, MetOp-SG A1, launched earlier this week from Europe’s Spaceport in Kourou, French Guiana, on board an Ariane 6 rocket. The
Airbus-built satellite, developed under the lead of the
European Space Agency (ESA) for
EUMETSAT (the European Organisation for the Exploitation of Meteorological Satellites), has established communication and is beginning its commissioning phase. This launch marks the start of a new era that will significantly enhance weather forecasting accuracy, and provide critical data for years to come.
Alain Fauré, head of Space Systems at Airbus, said: “The successful launch of MetOp-SG A1 is a landmark moment for Europe and for global weather forecasting. Having designed and built the first generation of MetOp satellites, we now see the first of this powerful new series in orbit. These satellites will be the sentinels of our planet, helping to deliver more accurate weather predictions that benefit citizens around the globe.”
MetOp-SG A1 is the first in a new series of six satellites that will ensure the continuity and enhancement of meteorological data from space into the mid-2040s. The programme consists of two types of satellites with three satellites each, 'A' and 'B', which carry complementary instrument packages. This first 'A' satellite is equipped with sophisticated atmospheric sounding and imaging instruments. The MetOp-SG B satellites carry instruments for microwave imaging and radar observations.
Monitoring atmospheric compositionThe advanced payload on MetOp-SG A1 includes the Infrared Atmospheric Sounding Interferometer - Next Generation (IASI-NG), which will provide highly detailed data for weather forecasting and climate research. It also carries the METimage visible and infrared imager, a Microwave Sounder, a Radio Occultation Sounder, and the innovative Multi-viewing, Multi-channel, Multi-polarisation Imager, designed to improve aerosol and cloud monitoring. Furthermore, the satellite hosts the Copernicus Sentinel-5 instrument, which will measure trace gases and pollutants to monitor atmospheric composition in unprecedented detail.
This mission is a testament to European collaboration, developed through a partnership between EUMETSAT, ESA, the European Union’s
Copernicus programme, the
French Space Agency (CNES), the
German Aerospace Center (DLR), the
UK Space Agency, and an industrial consortium led by Airbus.
The A series satellites are being built at Airbus in Toulouse, France, and the B series at Airbus in Friedrichshafen, in southern Germany. The nominal operational lifetime of each MetOp-SG satellite is 7.5 years, ensuring full operational coverage over a 21-year period.
Ariane 6 is a programme developed within the framework of ESA. As prime contractor and design authority for the launcher, ArianeGroup is responsible for development and production alongside its industrial partners. Arianespace, the launch service provider, oversees launch operations from the Guiana Space Centre, including the integration and deployment of the MetOp-SG A1 satellite into orbit.
