Timeline

Launch

In January 2025, ESA signed a contract with Arianespace to launch the satellite in the August 2025 on Ariane 6. [11] On 13 August 2025, MetOp-SG A1 with Sentinel-5A has launched into space on Ariane 62 L6003. [12]

First data

Less than three weeks after launch, EUMETSAT received and processed initial data from two instruments: the Microwave Sounder (MWS) and Radio Occultation Sounder (RO). [13] [14] On 15 September 2025, EUMETSAT has released the first images captured by the Multiviewing multichannel multipolarisation imager (3MI) on 28 August over the Mediterranean showing cloud structures over Italy and wildfire smoke near Greece. [15] On 07 October 2025, EUMETSAT has released the first Earth images from the satellite's METimage instrument, including an image of Hurricane Humberto. [16] [17]
