The return to flight of the Vega-C rocket should wait at the least yet one more day. The announcement, from Arianespace, the corporate managing the mission, got here lower than per week forward of the deliberate launch.
The mission, which is known as VV25, will see the launch of the Sentinel-1C spacecraft to a Solar-synchronous Earth orbit. The final time a Vega-C launched was on Dec. 20, 2022, which led to failure resulting from an anomaly on the higher stage.
Stéphane Israël, the CEO of Arianespace, the corporate overseeing the launch operations, confirmed the sooner or later slip throughout a prelaunch briefing on Wednesday.
“We could have a really restricted postponement of the mission resulting from further checks and certification on the launcher. We’ll push, hopefully by sooner or later, the mission,” Israël stated. “We’ll verify to you on Friday that it’s restricted to sooner or later, however that is, at present, I’d say, our baseline expectation.”
“As an built-in workforce throughout Arianespace, ESA, Avionics and so forth, we deem (it) applicable to conduct additional checks and additional actions to offer even higher flight worthiness to the launch,” stated Giulio Ranzo, the CEO of Avio, the corporate that can take over managing Vega-C launches starting with the VV29 mission. “It’s one thing we usually do in a tradition of doubt that the place we see one thing we’re not utterly happy with, we’d like to intervene and conduct extra checks.
“And I feel it will be significant, as a coverage we’ve got in Europe, to make sure the utmost flight worthiness, that we accomplish that, specifically for this very related flight in full transparency, by the best way, with the shopper. That is essential.”
Return to flight
The practically two-year hole between the final flight of a Vega-C rocket and the forthcoming one has been full of a sequence of exams to validate the corrective actions taken on the higher stage.
These included a pair of scorching fireplace exams of Avio’s Zefiro-40 engine, the latest of which happened on Oct. 3, 2024.
🔊Sound on (but it surely’s very loud)…
Hear the mighty energy of @Avio_Group‘s Zefiro-40 throughout testing. In simply two minutes this rocket stage burns by way of 36000 kg of propellant!

“The launcher is at present utterly built-in, has performed all of those exams for the readiness to the launch,” Ranzo stated. “We’ll proceed performing some checks and operational actions over the following few days and previous to launch, we are going to execute the launch readiness assessment, as we usually do, in cooperation with Arianespace, with the European Area Company, with the French Area Company (CNES) and with the shopper.”
The roughly 2.3 ton Sentinel-1C spacecraft might be positioned into its meant orbit at about 700 km (435 mi) above the Earth’s floor at an inclination of 98.19 levels. It is going to separate from the Vega-C’s higher stage about 1 hour and 43 minutes after launch and is designed to have a lifespan of seven.25 to 10 years.
The spacecraft is the sixth satellite tv for pc that’s a part of the Copernicus program to be launched by Arianespace. Copernicus is described by ESA as “the Earth commentary element of the European Union’s area program,” which “offers steady, free and dependable Earth commentary knowledge and companies to public authorities, firms and residents across the globe.”
This system is managed by the European Fee and funded by the European Union.
“Simply to provide you some figures, every month, greater than 150,000 merchandise primarily based on Sentinel-1 knowledge are printed and made accessible to customers and because the starting of the operations of the Sentinel-1, we’ve got generated over 30 petabytes of knowledge and greater than 14 million merchandise have been made accessible,” stated Christoph Kautz, the Director for Satellite tv for pc Navigation and Earth Statement for the European Fee.
“So, it’s actually a vital mission for us and total I can say that when you look additionally into the long run, and also you have a look at market forecasts, you will notice that the general revenues of the worldwide Earth commentary knowledge and worth added service market are projected to achieve a number of billions of Euros. So economically, clearly, it’s a vital mission for us.”
Way forward for Vega-C
Beginning in 2025, Israël stated he anticipated an annual launch cadence of 4 Vega-C flights per 12 months, which is able to start with the launch of a P-band artificial aperture radar satellite tv for pc known as Biomass.
Ranzo stated the European member states are pushing for a plan that will “improve the manufacturing capability all the best way as much as roughly six launches per 12 months.” He stated it could take about 2.5 years to achieve that time.
“This can require that we put in operation a so-called ‘launcher pre-integration constructing’ that can allow us to combine the launcher, not on the launch pad, however on a close-by facility that was formally utilized by Ariane 5,” Ranzo stated. “So, whereas we might be launching one launcher on the pad, in parallel, we’ll be already getting ready the following launcher for launch.”
