MTG-I1, officially designatedMeteosat-12 upon entering operational service, is the first of four imaging satellite of theMeteosat Third Generation (MTG) system developed byEUMETSAT in cooperation with theEuropean Space Agency (ESA). Launched on 13 December 2022,[4] it became fully operational on 7 January 2024,[5][6] replacingMSG-4 as the prime geostationarymeteorological satellite over Europe and Africa.[1][7][8][9]

Timeline

[edit]

Development

[edit]
  • In November 2010,ESA awarded a contract toAstrium (now part ofAirbus Defence and Space) to develop and build four MTG-I satellites. At the time, the launches were expected to happen in 2017.[10]
  • In November 2012, ESA and EUMETSAT signed an agreement to cooperate on MTG Program.[11]

Launch campaign

[edit]
  • In March 2022, MTG-I1 satellite had completed all functional and environmental tests and was pronounced ready for transport to the launch site.[12]
  • On 29 September 2022, the MTG-I1 satellite leftMarseille on board theMNToucan cargo ship and arrived atKourou on 18 October.[13][14]
  • On 6 December 2022, ESA announced that the MTG-I1 satellite would launch no earlier than 13 July 2022, 20:30 UTC[4]
  • On 12 December 2022, Arianespace rolled out theAriane 5 carrying the MTG-I1 satellite and two other satellites (Galaxy-35 & 36 forIntelsat) to the pad.[15]
  • Ariane 5 with the MTG-I1 satellite launched on 13 December 2022 at 20:20 UTC towardgeostationary transfer orbit.[16][17]

In orbit

[edit]
  • In May 2023, ESA published first preliminary images from the MTG-I1 mission.[18]
