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

With this mission, ESA completes the primary trio within the Meteosat Third Technology (MTG) constellation. MTG-I2, which was 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.
A revolution in forecasting excessive climate occasions
Positioned 36,000 kilometres above the Earth in geostationary orbit, MTG-I2 will keep a hard and fast place, permitting it to behave as a “hawk’s eye” over the planet’s floor. Its primary instrument, the Versatile Mixed Imager, will present a speedy scanning service over Europe, delivering high-resolution observations each 2.5 minutes.
This very excessive refresh price represents a paradigm shift for instant climate prediction, bettering forecasts and proving important for the monitoring of disasters comparable to floods and wildfires. The know-how will make it attainable to trace atmospheric fronts in actual time, anticipate the formation of extreme storms or DANA and enhance the monitoring of fires and air air pollution throughout Europe, with a selected concentrate on the Mediterranean and North Africa.
The satellite tv for pc additionally carries the Lightning Imager, a sensor able to detecting and mapping particular person lightning discharges each day and night time. Integrating these satellites will make it attainable to create a “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 for Ariane 6 and the primary flight wherein Europe’s heavy-lift launcher has carried a satellite tv for pc to a Geostationary Switch Orbit (GTO). To achieve the furthest distance achieved by this rocket so far, the configuration with two P120C solid-fuel boosters was used.
After satellite tv for pc separation, profitable contact was established with the spacecraft. Floor groups are actually coordinating the deployment of the photo voltaic panels and the gradual activation of its propulsion system to lift the perigee and alter its trajectory in direction of its remaining geostationary orbit. As soon as it has been reoriented in direction of Earth, the preliminary operations part (LEOP) will finish and scientific calibration will start.
Industrial cooperation and the way forward for the programme
The event of the MTG household has been led by ESA along with a European industrial consortium headed by Thales Alenia House, with assist from OHB System and Leonardo. As soon as the calibration part has been accomplished, duty for working the satellites and distributing knowledge to the worldwide scientific group will go to Eumetsat.
This fleet ensures continuity of the observations begun with the Meteosat Second Technology collection (operational between 2002 and 2015). From 2033, a second collection of MTG satellites is anticipated to be launched in phases, making certain continuity of the service past 2040.
