The European Space Agency launched the MTG-I2 weather satellite aboard an Ariane 6 rocket from Kourou, French Guiana, completing the first trio of the Meteosat Third Generation constellation. According to the European Space Agency, the mission places the new imaging satellite into a geostationary orbit 36,000 kilometres above Earth to improve the forecasting of severe storms, wildfires, and floods across Europe, the Mediterranean, and North Africa.
Revolution in Forecasting Extreme Weather Events
Operating from a fixed position at an altitude of 36,000 kilometres, the MTG-I2 satellite relies on its primary instrument, the Flexible Combined Imager, to monitor atmospheric changes. According to the European Space Agency, this instrument delivers high-resolution observations over Europe every 2.5 minutes through a rapid-scan service.
This 2.5-minute refresh rate provides a paradigm shift for nowcasting, giving meteorologists tools to track atmospheric fronts in real time and anticipate severe storms or DANA events. According to the European Space Agency, the satellite also features a Lightning Imager sensor that detects and maps individual lightning discharges day and night. These instruments will combine to form a three-dimensional representation of lightning, winds, cloud dynamics, and greenhouse gases known as the “weather cube.”
Did you know? The Meteosat Third Generation constellation builds on decades of observation, directly succeeding the Meteosat Second Generation series that operated between 2002 and 2015, with a second family of MTG satellites planned for launch starting in 2033.
Ariane 6 Reaches Geostationary Transfer Orbit
The launch of MTG-I2 marked the ninth mission for the Ariane 6 rocket and the first time the European heavy-lift launcher has delivered a satellite to a Geostationary Transfer Orbit. According to the European Space Agency, the rocket flew with a configuration of two P120C solid-fuel boosters to achieve this distance.

Ground teams established contact with the spacecraft following its separation from the rocket. According to the European Space Agency, operators are currently overseeing the deployment of the solar panels and igniting the propulsion system to raise the perigee, fine-tune the trajectory, and repoint the spacecraft toward Earth to conclude the Launch and Early Orbit Phase.
Industrial Cooperation and Operational Future
Development of the Meteosat Third Generation family is managed by the European Space Agency alongside an industrial consortium led by Thales Alenia Space, with contributions from OHB System and Leonardo. According to the European Space Agency, responsibility for routine operations and distributing data to international researchers will transition to Eumetsat once the satellite completes its scientific calibration phase.
The current fleet ensures continuous Earth observation data well into the future. According to the European Space Agency, the operational lifespan of these spacecraft bridges the gap toward a second family of MTG satellites scheduled for staggered launches beginning in 2033, securing service continuity past the year 2040.
