The European Space Agency (ESA) has reached a historic milestone in Earth remark and meteorological science, amid the local weather disaster and meteorological disasters. The MTG-I2 (“Meteosat Third Technology Imager-2”) satellite tv for pc has been efficiently launched aboard the Ariane 6 rocket from the European Spaceport in Kourou, French Guiana.

With this mission, ESA completes the primary trio within the Meteosat Third Technology constellation (MTG). MTG-I2, efficiently launched on 27 July, is the second imaging satellite tv for pc on this fleet and joins the primary Imager (launched in 2022) and the Sounder (launched in 2025). As soon as its commissioning part is full, the constellation will start working at full capability.
Revolution in forecasting excessive climate occasions
Positioned at an altitude of 36,000 kilometres in geostationary orbit, MTG-I2 will keep a hard and fast place, performing as a watchful eye over the Earth’s floor. Its major instrument, the Versatile Mixed Imager, will present a rapid-scan service over Europe, delivering high-resolution observations each 2.5 minutes.
This very excessive refresh fee represents a change of paradigm for nowcasting, enhancing short-term climate forecasts and proving very important for the monitoring of disasters comparable to floods or wildfires. The expertise will make it attainable to trace atmospheric fronts in actual time, anticipate the formation of extreme storms or DANA occasions and enhance the monitoring of fires and air air pollution throughout Europe, with a specific concentrate on the Mediterranean and North Africa.
As well as, the satellite tv for pc contains the Lightning Imager, a sensor able to detecting and mapping particular person lightning discharges each day and evening. Integrating these satellites will make it attainable to construct the “climate dice”, a three-dimensional illustration of lightning, winds, cloud dynamics and greenhouse gases.
A milestone for the Ariane 6 rocket and the subsequent operational steps
The launch marked the ninth mission of Ariane 6 (source in Spanish) and the primary time the European heavy-lift rocket has carried a satellite tv for pc to a Geostationary Switch Orbit (GTO). To achieve the furthest distance achieved by this launcher up to now, it flew in a configuration with two P120C solid-fuel boosters.
After satellite tv for pc separation, contact with the spacecraft was efficiently established. Floor groups are actually overseeing the deployment of the photo voltaic panels and the gradual ignition of its propulsion system to boost the perigee and fine-tune its trajectory in direction of its last geostationary orbit. As soon as it has been repointed in direction of Earth, the Launch and Early Orbit Section (LEOP) will finish and scientific calibration can start.
European industrial cooperation and the way forward for the programme
Growth of the MTG household has been led by ESA along with a European industrial consortium headed by Thales Alenia Area, with assist from OHB System and Leonardo. As soon as the calibration part is full, accountability for working the satellites and distributing knowledge to the worldwide scientific neighborhood will cross to Eumetsat.
This fleet ensures continuity of the observations begun by the Meteosat Second Technology sequence (operational between 2002 and 2015). From 2033, a second household of MTG satellites is anticipated to be launched in levels, making certain the continuity of the service past 2040.
