Live protection: Avio to release spacecraft to keep an eye on plant health and ocean conditions

The penultimate Vega-C launch of the year is set up to fly from Europe’s Spaceport in French Guiana Monday night.

The launch, bring the classification VV30, hosts 2 spacecraft onboard: the ocean- and atmosphere-monitoring Copernicus Sentinel-3C, handled by the European Organisation for the Exploitation of Meteorological Satellites( EUMETSAT), and the plant health-monitoring Fluorescence Explorer(FLEX), handled by the European Space Agency(ESA).

Liftoff of the four-stage rocket from Ensemble de Lancement Vega at Europe’s Spaceport in French Guiana is set up for 10:21 p.m. regional time (9:21 p.m. EDT/ 0121 UTC/ 3:21 a.m. CEST). Implementation of the Sentinel-3C is set up for about an hour after liftoff and FLEX will release almost an hour after that.

Spaceflight Now will have live protection starting about an hour prior to liftoff.

The Vega-C rocket stands at a height of 34.8 meters(114.2 ft.)and includes 4 different phases. 3 solid-propellant motors power the very first 3 phases( P120C, Zefiro-40, and Zefiro-9)and the Attitude Vernier Upper Module (AVUM+)is the re-ignitable liquid-fueled upper phase.

Avio produces the 2nd and 3rd phases, while the P120C is established by Europropusion, a joint endeavor in between Avio and Arianespace.

The AVUM+utilizes a Ukrainian RD-843 engine and can carrying out approximately 7 special burns. The phase is sustained by hypergolic propellants unsymmetrical dimethylhydrazine (UDMH) and utilizes dinitrogen tetroxide (N₂O₄as the oxidizer.

The VV30 objective will be the 2nd handled entirely by Italian business, Avio, and not collectively with Arianespace. This will likewise be the 2nd Vega-C launch of 2026 and the 8th overall.

The Vega-C rocket has the ability of providing up to 2,300 kg of mass to a 700-km Sun-Synchronous Orbit (SSO), which has to do with 50 percent more capability than its predecessor, Vega. The last launch of the initial Vega rocket (VV24) occurred in September 2024.

The 2 spacecraft on this specific objective will be released to an elevation of 820 km with a disposition of 98.6 degrees. It will take about 116 minutes to release both satellites.

The very first payload be released, the Copernicus Sentinel-3C. It’s the 3rd in the Sentinel-3 series is set up to be launched from the AVUM + upper phase one hour after liftoff.

The spacecraft is geared up with a fit of science instruments developed to keep an eye on ocean color, sea-level increase, and topography. It likewise tracks climatic modifications and wildfires.

“The oceans are definitely at the heart of this story. They take in around 90 percent of the excess heat produced by human activities, protecting us from even higher effects of warming,” stated Phil Evans, Director-General of EUMETSAT throughout a prelaunch news instruction.

“But the oceans are paying a rate with increasing temperature levels, modifications to communities, speeding up water level increase, and systems such as Sentinel-3C are important and important facilities that can offer us with constant details about what’s going on in the oceans.”

Onboard the Vega-C rocket, nestled under the secondary payload adapter called Vespa, is FLEX. The 397 kg (875 pounds) spacecraft is the 8th in a series of Earth Explorer objectives established through ESA’s FutureEO program.

Throughout an approximately 3.5-year prepared objective, FLEX will utilize its Fluorescence Imaging Spectrometer (FLORIS) to assist scientists comprehend “how carbon moves in between plants and the environment and how photosynthesis impacts the carbon and water cycles,” according to ESA.

Simonetta Cheli, ESA’s Director of Earth Observation Programmes, stated that this objective has to do with technology development, considered that the FLORIS instrument will be running in the 500-780 nanometer spectrum variety, flying in tandem with Sentinel-3C.

“That’s likewise why we introduce them together due to the fact that every one of those 2 satellites will supply appropriate details: another on the status of the health of the plants. The other another on the climatic context and all what is surrounding it,” Cheli stated. “They will fly one kilometer apart from among the other with a couple of minutes, I would state seconds apart. And this FLEX objective will have a review duration of 27 days. It’s predicted to live 3 and a half years, however as you have actually seen, the majority of the Earth Explorer objective have actually lived well beyond their preliminary life time.”

The release time for FLEX is arranged for about one hour 56 minutes after liftoff.
