The penultimate Vega-C launch of the year is arranged 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).”YouTube video player” 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 arranged for about an hour after liftoff and FLEX will release almost an hour after that.”https://www.youtube.com/embed/6gBHkNXsv8M?si=NzPJXGAUp2L6ytOB” Spaceflight Now will have live protection starting about an hour prior to liftoff.”678″ “bookmark” 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.”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” Avio produces the 2nd and 3rd phases, while the P120C is established by Europropusion, a joint endeavor in between Avio and Arianespace.”mce_SELRES_start”The AVUM+utilizes a Ukrainian RD-843 engine and can carrying out approximately 7 special burns.

4as the oxidizer.The VV30 objective will be the 2nd handled exclusively 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) happened 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.

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 offer appropriate details: another on the status of the health of the greenery. 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 set up for about one hour 56 minutes after liftoff.
