Europe’s most advanced weather satellite, MTG-S1, successfully launched into orbit on July 1, 2025, marking a significant milestone in meteorological forecasting capabilities. The satellite promises to revolutionize weather prediction and early warning systems with unprecedented three-dimensional atmospheric data.
Key Facts:
- Launch: July 1, 2025, aboard SpaceX Falcon 9 from Cape Canaveral
- Mission: Hosts EU’s Copernicus Sentinel-4 mission
- Technology: First space-based infrared sounder for Europe
- Coverage: Europe, Africa, and surrounding regions from 36,000 km above Earth
Historic Launch Success
The MTG-S1 satellite launched aboard a SpaceX Falcon 9 rocket from Cape Canaveral, generating applause at EUMETSAT headquarters in Darmstadt, Germany. Staff and media watched the historic moment unfold as the satellite separated from its launcher and continued its journey into orbit.
Following separation, MTG-S1 entered its Launch and Early Operations Phase, with engineers now activating systems and guiding it to its geostationary orbital position approximately 36,000 kilometers above the equator.
Revolutionary Technology
The satellite’s Infrared Sounder represents a breakthrough in meteorological technology. This instrument captures data on temperature, humidity, and trace gases to generate three-dimensional maps of the atmosphere.
Unlike traditional systems, MTG-S1 shifts forecasting from flat imagery to comprehensive three-dimensional atmospheric views, allowing meteorologists to observe weather patterns at every altitude level.
“MTG-S will, for the first time, offer a space-based view of the full lifecycle of convective storms. This will provide tremendous support to national meteorological services in carrying out their vital work, helping to save lives, reduce disruption, and strengthen resilience.”
— EUMETSAT Director-General Phil Evans
Enhanced Weather Forecasting Capabilities
The satellite will provide Europe’s national meteorological services with high-frequency data on atmospheric conditions. This enhanced capability will enable forecasters to detect the earliest signs of severe weather and extend lead times for weather warnings.
MTG-S1 will generate a completely new type of data product, especially suited to nowcasting severe weather events. The system will help detect and predict rapidly evolving and potentially dangerous weather systems, supporting the Early Warning for All (EW4All) initiative.
“MTG-S1 will bring a treasure trove of new data that will provide National Meteorological and Hydrological Services with improved information for their weather prediction. Every time we check the weather, we rely on something bigger than technology. We rely on international trust, data, and cooperation. Reliable forecasts don’t happen by accident. They are made possible by a system of global solidarity. EUMETSAT is a key part of that global solidarity.”
— WMO Secretary-General Celeste Saulo
Aviation Safety Benefits
The aviation industry stands to gain significantly from MTG-S1’s capabilities. By providing three-dimensional pictures of temperature, wind, and humidity that evolve over time, the satellite will help identify turbulent regions.
Turbulence remains a perennial hazard for air traffic, causing both discomfort and danger for pilots and passengers. MTG-S1’s data will enable smarter flight planning and reduce risks in aviation operations.
Climate Monitoring Applications
Beyond weather forecasting, the satellite’s Infrared Sounder can detect greenhouse gases including carbon monoxide, carbon dioxide, methane, and ozone. This capability supports long-term climate change monitoring efforts and provides crucial data for environmental research.
The satellite will contribute to the Copernicus Atmosphere Monitoring Service, which protects public health and strengthens environmental monitoring across Europe.
European Collaboration Success
The mission represents a successful collaboration between multiple European organizations and dozens of industry partners. This achievement demonstrates the power of international cooperation in advancing scientific capabilities.
“It is thanks to the outstanding work our teams have done with EUMETSAT, the European Commission and dozens of European industry partners, that we are able to now look forward to more accurate and timely ways of predicting storm events and air pollution.”
— European Space Agency Director of Earth Observation Programmes Simonetta Cheli
“This achievement is a powerful example of how European cooperation can provide vital data in support of services such as the Copernicus Atmosphere Monitoring Service that protect public health, strengthen environmental monitoring, and improve lives across Europe.”
— European Commission Director for Space Policy, Earth Observation and Satellite Navigation Christoph Kautz
Global Impact
While primarily serving European meteorological services, the benefits of MTG-S1 will extend globally. The Meteosat Third Generation satellite system will enable more precise monitoring of Earth’s changing atmosphere, land, and oceans.
From its strategic position aligned with Earth’s rotation, MTG-S1 will maintain continuous surveillance of Europe, Africa, and surrounding regions, contributing to worldwide weather forecasting improvements and climate research.
What Happens Next
MTG-S1 is now undergoing commissioning and testing phases before becoming fully operational. During this period, engineers will validate all systems and ensure the satellite meets performance specifications.
Once operational, the satellite will begin providing continuous atmospheric monitoring data to meteorological services across Europe, marking a new era in weather prediction capabilities.
