Mission Details
MTG-S1/Sentinel-4A
MTG (Meteosat Third Generation) is the follow-up system to the Meteosat MSG series of geostationary satellites.
The satellite system will consist of a twin configuration of 3-axis-stabilised satellites: the Imaging mission satellite (MTG-I) and the Sounding mission satellite (MTG-S).
The payload proposed for MTG-S would have an Infrared Sounder (IRS) and Ultra-violet Visible Near-infrared (UVN) Sounder, the later of which is included as the Sentinel-4 mission
The Sentinel-4 mission focuses on monitoring trace gas concentrations and aerosols in the atmosphere to support operational services covering air-quality near-real-time applications, air-quality protocol monitoring, and climate protocol monitoring. The specific objective of Sentinel-4 is to support this with a high revisit time over Europe.
The Sentinel-4/UVN instrument is a high-resolution spectrometer system operating with 3 designated bands in the solar reflectance spectrum, covering the ultraviolet (305-400 nm), visible (400-500 nm), and near-infrared (750-775 nm) bands. The central Sentinel-4/UVN instrument parameters are a spatial sampling of 8 km over Europe and a fast repeat cycle over Europe and North Africa (Sahara) of 60 minutes.
The respective spectral resolution is 0.5 nm in the ultraviolet and visible bands, with the goal of 0.12 nm in near-infrared.
Payloads: 1  Total Mass: 3,800.0 kg  Geostationary Transfer Orbit

While our forest mission - Biomass - is preparing for liftoff, another mission has just started its journey to the launch site!
These pictures were taken at the departure of the MTG-S1 mission.
MTG-S1, the first European geostationary satellite to carry an Infrared Sounder instrument, also hosts the Copernicus Sentinel-4 mission.

Hello, Florida
MTG-S1 and @CopernicusEU Sentinel-4 have safely reached Cape Canaveral harbour after their boat ride. Next step? Unloading and heading to the launch site.
Once in orbit, MTG-S1 will capture data on temperature, humidity, wind and trace gases with its Infrared Sounder instrument while Sentinel-4 will track air quality over Europe.

SpaceX is targeting Tuesday, July 1 for a Falcon 9 launch of the Eumetsat MTG-S1 mission to geosynchronous transfer orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The 150-minute window opens at 5:04 p.m. ET. If needed, a backup launch opportunity is available on Wednesday, July 2 at the same time.

A live webcast of this mission will begin about 15 minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This will be the ninth flight for the Falcon 9 first stage booster supporting this mission, which previously launched Crew-9, RRT-1, Firefly Blue Ghost Mission 1, Fram2, SXM-10, and three Starlink missions. After stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean...

Falcon 9 first stage B1085-9 is vertical at LC-39A with EUMETSAT's MTG-S1 satellite ahead of launch in just over 90 minutes at 21:04 UTC. MTG-S1 also hosts ESA's Sentinel-4A payload. Weather is not looking great, with only a 20% chance of favorable weather conditions.

Погода - 20%
