The top of Ariane 6, flight VA264, that will launch Europe\u2019s first MetOp Second Generation, MetOp-SG-A1, weather satellite \u2013 which hosts Copernicus Sentinel-5 as part of its instrument package. This picture was taken from the upper level of the mobile gantry \u2013 a 90-m-tall rocket hangar on wheels \u2013 on 11 August 2025 during the final stages in preparation before liftoff. Inside the white dome \u2013 known as the fairing \u2013 52\u00a0m above ground level\u00a0is MetOp-SG-A1, the fairing will split in two once the rocket has escaped our atmosphere revealing the satellite to space.<\/p>\n
MetOp-SG-A1 is the first in a series of three successive pairs of satellites.\u00a0The mission as a whole not only ensures the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more than 20 years, but also offers enhanced accuracy and resolution compared to the original MetOp mission \u2013 along with new measurement capabilities to expand its scientific reach.<\/p>\n
MetOp-SG-A1, carries six instruments: a next-generation infrared atmospheric sounder, a microwave sounder, a multispectral imaging radiometer, a novel multiviewing, multichannel, multipolarisation imager, a radio occultation sounder (which is also embarked on the MetOp-SG-B satellites), and the European Commission\u2019s Copernicus Sentinel-5 spectrometer.<\/p>\n
Building on the success of the Copernicus Sentinel-5 Precursor satellite, the new Copernicus Sentinel-5 introduces an advanced imaging spectrometer. The first of these cutting-edge instruments, Sentinel-5A, is integrated into MetOp-SG-A1, and will work in synergy with other onboard instruments.<\/p>\n
The missions will launch on an Ariane 6 with two boosters.\u00a0Ariane 6\u00a0is Europe\u2019s heavy launcher and a key element of ESA\u2019s efforts to ensure autonomous access to space for Europe\u2019s citizens. Its modular and versatile design allows it to launch all missions from low-Earth orbit into deep space. Standing over 60 metres tall, Ariane 6 can weigh almost 900 tonnes when launched with a full payload.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
