The return to flight of the Vega-C rocket must wait no less than yet another 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 resulted in failure as a consequence of 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 can have a really restricted postponement of the mission as a consequence of 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 might 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 fully glad with, we’d like to intervene and conduct extra checks.
“And I feel it will be important, as a coverage we’ve got in Europe, to make sure the utmost flight worthiness, that we achieve this, particularly for this very related flight in full transparency, by the best way, with the shopper. That is essential.”
Return to flight
The almost two-year hole between the final flight of a Vega-C rocket and the forthcoming one has been crammed with a collection of exams to validate the corrective actions taken on the higher stage.
These included a pair of scorching hearth exams of Avio’s Zefiro-40 engine, the latest of which came about on Oct. 3, 2024.
🔊Sound on (however it’s very loud)…
Hear the mighty energy of @Avio_Group‘s Zefiro-40 throughout testing. In simply two minutes this rocket stage burns by 36000 kg of propellant!

“The launcher is at the moment fully built-in, has carried out all of those exams for the readiness to the launch,” Ranzo stated. “We’ll proceed performing some checks and operational actions over the subsequent few days and previous to launch, we are going to execute the launch readiness evaluate, 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 will likely be positioned into its supposed orbit at about 700 km (435 mi) above the Earth’s floor at an inclination of 98.19 levels. It would 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 statement part of the European Union’s house program,” which “supplies steady, free and dependable Earth statement knowledge and providers to public authorities, corporations and residents across the globe.”
This system is managed by the European Fee and funded by the European Union.
“Simply to offer you some figures, every month, greater than 150,000 merchandise based mostly on Sentinel-1 knowledge are printed and made obtainable to customers and for the reason that starting of the operations of the Sentinel-1, we’ve got generated over 30 petabytes of knowledge and greater than 14 million merchandise had been made obtainable,” stated Christoph Kautz, the Director for Satellite tv for pc Navigation and Earth Remark for the European Fee.
“So, it’s actually a vital mission for us and general I can say that should you look additionally into the longer term, and also you take a look at market forecasts, you will notice that the general revenues of the worldwide Earth statement 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 referred to as Biomass.
Ranzo stated the European member states are pushing for a plan that may “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 will likely be launching one launcher on the pad, in parallel, we’ll be already getting ready the subsequent launcher for launch.”
