Three ESA-built satellites on present in France

ESA’s Fluorescence Earth Explorer satellite tv for pc, referred to as FLEX, along with the Meteosat Third Technology (MTG) Imager climate satellite tv for pc, MTG-I2, in addition to the subsequent satellite tv for pc within the European Fee’s Copernicus programme, Sentinel-3C, had been all on present on the media occasion hosted by Thales Alenia House at their cleanrooms in Cannes, France.

Members of the media had a possibility to hearken to displays and conduct interviews with key mission companions in addition to {photograph} and movie all three spectacular spacecraft and their devices. This was the final public view of the satellites earlier than they’re transported to the European Spaceport in French Guiana, the place they’re scheduled for liftoff on ESA’s Ariane 6 and Vega-C launchers.

The three missions display the excellence of European trade within the area of Earth statement. Leaders and specialists from ESA’s Earth Statement Directorate, Eumetsat, the European Fee, Thales Alenia House and different companions had been on web site in Cannes to offer speeches and communicate individually to journalists.

ESA’s Earth Explorer Missions Programme Supervisor, Dirk Bernaerts, mentioned, “We’re thrilled to see every of those missions of their ultimate phases earlier than launch. Every one of many satellites may have an essential function to play in offering knowledge to watch and measure our planet’s ecosystems, from vegetation well being to extra correct forecasting of climate occasions and exact monitoring of circumstances of sea ice, oceans and land. We sit up for seeing them launch later this 12 months and take this chance to reiterate the significance of European collaboration in every mission’s success.”

ESA’s Director of Earth Statement Programmes, Simonetta Cheli, mentioned, “Many thanks go to all of the groups which have contributed to the design and realisation of the FLEX Earth Explorer mission, MTG-I2 with Eumetsat and Sentinel-3C with the European Fee. I’m pleased with the dedication and experience that ESA brings to the event of those Earth statement missions. The final word purpose for every satellite tv for pc is, in fact, to supply world-class knowledge merchandise that may enhance the lives of residents, benefitting individuals in quite a few methods: from extra well timed excessive climate warnings, to a greater understanding of the vegetation photosynthesis course of and its affect on the carbon and water cycles, in addition to the operational provision of correct knowledge supporting prediction and forecasting, and long run observations that may enhance future local weather fashions. We now sit up for some profitable launches later within the 12 months.”

FLEX able to detect world plant well being

FLEX is the eighth progressive Earth Explorer mission developed by ESA’s FutureEO programme at the side of the science group. FLEX is designed to measure and map the well being of vegetation from house by detecting the fluorescent sign emitted by vegetation.

Photosynthesis is among the most elementary processes on Earth and is important for sustaining life. Most individuals understand it because the mechanism that enables vegetation to develop by consuming carbon dioxide and releasing oxygen. Nevertheless, few could realise that as vegetation photosynthesise, additionally they emit a really faint fluorescence sign.

Fluorescence is invisible to the bare eye, however FLEX will have the ability to detect it with its fluorescence imaging spectrometer, or FLORIS for brief. The instrument supplies knowledge on how the sign varies in response to environmental circumstances and the well being or stress of the vegetation.

Each FLEX and Copernicus Sentinel-3C can be launched on the identical Vega-C flight, due for liftoff in September 2026. As soon as operational, FLEX will fly in the identical orbit because the Sentinel-3 mission, which is able to present FLEX with required info on the environment and Earth’s floor properties.

Ralf Bock, ESA’s FLEX Mission Supervisor, famous, “Due to the excellence and dedication of greater than 30 European corporations we’ve accomplished the difficult improvement of the FLEX satellite tv for pc and can quickly be prepared for launch. We’re trying ahead to demonstrating the innovation within the FLEX Earth Explorer mission that guarantees to provide thrilling new scientific insights into our Earth system and advance our understanding of the function of vegetation within the carbon cycle.”

Sentinel-3C to proceed monitoring for Copernicus

Copernicus Sentinel-3C is the third satellite tv for pc for the Sentinel-3 mission, which captures operational knowledge and supplies companies for close to actual time responses in addition to for long run local weather monitoring over Earth’s land surfaces, inland water, ice, oceans and environment. It’s a part of the Copernicus fleet of satellites, which contributes altimetry knowledge and optical imagery to the European Fee’s Copernicus Earth statement programme. Sentinel-3 is usually thought of because the ‘workhorse’ mission for Copernicus because of the breadth of knowledge it supplies, which ranges from altimetry to spectrometry and radiometry in infrared and thermal channels.

Identical to the 2 Sentinel-3 satellites already in orbit, Sentinel-3C carries a set of cutting-edge devices that measure the peak of the ocean, sea and ice floor temperatures, ocean color and sea ice thickness. Over land, it measures vegetation, wildfires, the variations of ice sheet in addition to the water top of inland lakes and rivers. Its knowledge assist us perceive multi-scale, world local weather dynamics of the Earth System and are freed from cost to customers worldwide.

ESA’s Sentinel-3 Mission Supervisor, Nic Mardle, famous, “We’re delighted that Sentinel-3C is now becoming a member of the -A and -B satellites in orbit, to proceed the Sentinel-3 mission into the subsequent decade. This mission tracks many phenomena – sea-level rise, ice sheet melting, wildfires and flooding are only a few examples – that are so carefully associated to the climatic modifications we are actually experiencing.”

MTG-Imager the storm nowcaster

Meteosat Third Technology-Imager2 (MTG-I2) would be the first of the three satellites proven at right this moment’s occasion to be rolled out on the launch pad. It’s a part of the MTG constellation for Eumetsat – two are already in orbit – and it’ll produce pictures for climate forecasting in Europe in unprecedented element. This mission supplies utterly new knowledge merchandise and capabilities for European climate companies, particularly suited to nowcasting of extreme climate occasions. MTG-I2 is scheduled for launch on Ariane 6 this summer time.

The MTG-Imager satellites carry two devices, a Lightning Imager and a Versatile Mixed Imager. The Lightning Imager presents utterly new capabilities for European meteorological satellites by constantly monitoring for lightning. By doing this from geostationary orbit, which is at an altitude of about 36 000 km above the equator, it may well scan greater than 80% of Earth’s floor seen from that viewpoint.

The Versatile Mixed Imager, then again, builds an image of fast-evolving climate techniques and can be utilized to difficulty well timed climate warnings. It’s significantly related for air visitors security. It is ready to scan the complete Earth disc in simply 10 minutes and may scan Europe and northern Africa each 2.5 minutes.

When MTG is totally operational, it’s anticipated to provide at the least 50 occasions extra knowledge than the earlier Meteosat Second Technology (MSG) satellites.

ESA’s MTG Mission Supervisor, James Champion, mentioned, “Reaching this milestone means we’re a step nearer to having all three MTG satellites in orbit. I wish to thank all of the groups all through Europe whose dedication has enabled us to get up to now – it helped that that is the second MTG-Imager and we had been in a position to work extra fluidly as a group through the satellite tv for pc’s construct and check section. Everyone seems to be now very a lot trying ahead to starting the launch marketing campaign in French Guiana.”

Collaboration

FLEX is an ESA mission and can be operated from ESA’s European House Operations Centre (ESOC) in Darmstadt, Germany. Mission management for FLEX can be in coordination with Eumetsat for tandem flight with Copernicus Sentinel-3.

The opposite two satellites had been constructed for European companions. MTG-I2 is developed by ESA and can be operated by Eumetsat, whereas Sentinel-3C is constructed for the European Fee’s Copernicus programme and can be collectively operated by ESA and Eumetsat.

Thales Alenia House France leads the commercial consortium for MTG as the general prime contractor for the MTG mission. It’s also the prime contractor for the Sentinel-3C satellite tv for pc (and two of its devices) in addition to for ESA’s FLEX satellite tv for pc. Leonardo (Italy), OHB System (Germany) and Airbus (Spain) had been additionally prime contractors and major companions on a number of of the missions.
