The return to flight of the Vega-C rocket must wait at the very least yet one more day. The announcement, from Arianespace, the corporate managing the mission, got here lower than every 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 resulting from an anomaly on the higher stage.
Stéphane Israël, the CEO of Arianespace, the corporate overseeing the launch operations, confirmed the someday slip throughout a prelaunch briefing on Wednesday.
“We could have a really restricted postponement of the mission resulting from extra checks and certification on the launcher. We are going to push, hopefully by someday, the mission,” Israël mentioned. “We are going to verify to you on Friday that it’s restricted to someday, however that is, as we speak, I might say, our baseline expectation.”
“As an built-in group throughout Arianespace, ESA, Avionics and so forth, we deem (it) acceptable to conduct additional checks and additional actions to supply even higher flight worthiness to the launch,” mentioned Giulio Ranzo, the CEO of Avio, the corporate that may 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 aren’t utterly glad with, we’d like to intervene and conduct extra checks.
“And I feel it will be important, as a coverage we now have 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 client. 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 stuffed with a collection of assessments to validate the corrective actions taken on the higher stage.
These included a pair of scorching hearth assessments of Avio’s Zefiro-40 engine, the latest of which came about 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 carried out all of those assessments for the readiness to the launch,” Ranzo mentioned. “We are going to proceed performing some checks and operational actions over the subsequent few days and previous to launch, we’ll execute the launch readiness evaluation, as we usually do, in cooperation with Arianespace, with the European Area Company, with the French Area Company (CNES) and with the client.”
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’s 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 “gives steady, free and dependable Earth commentary information 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 provide you some figures, every month, greater than 150,000 merchandise based mostly on Sentinel-1 information are printed and made obtainable to customers and for the reason that starting of the operations of the Sentinel-1, we now have generated over 30 petabytes of information and greater than 14 million merchandise had been made obtainable,” mentioned Christoph Kautz, the Director for Satellite tv for pc Navigation and Earth Statement for the European Fee.
“So, it’s actually an important mission for us and general I can say that if you happen to look additionally into the longer term, and also you take a look at market forecasts, you will note that the general revenues of the worldwide Earth commentary information and worth added service market are projected to succeed in a number of billions of Euros. So economically, clearly, it’s an important mission for us.”
Way forward for Vega-C
Beginning in 2025, Israël mentioned he anticipated an annual launch cadence of 4 Vega-C flights per yr, which is able to start with the launch of a P-band artificial aperture radar satellite tv for pc referred to as Biomass.
Ranzo mentioned 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 yr.” He mentioned it could take about 2.5 years to succeed in that time.
“This can require that we put in operation a so-called ‘launcher pre-integration constructing’ that may 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 mentioned. “So, whereas we will likely be launching one launcher on the pad, in parallel, we’ll be already making ready the subsequent launcher for launch.”
