Europe’s flagship Ariane 5 rocket retired in 2023, a year before its replacement—the Ariane 6—debuted on its first test flight from the Guiana Space Center. The first operational flight of the Ariane 6 delivered a French military spy satellite to orbit March 6. The smaller Vega C rocket successfully launched in December, two years after officials grounded the vehicle due to an in-flight failure.
ESA funded development of the Ariane 6 and Vega C in partnership with ArianeGroup, a joint venture between Airbus and Safran, and the Italian defense contractor Avio.
For the moment, Europe’s launcher program is back on track to provide autonomous access to space, a capability European officials consider a strategic imperative. Philippe Baptiste, France’s minister for research and higher education, said after the Ariane 6 flight earlier this month that the launch was “proof” of European space sovereignty.
“The return of Donald Trump to the White House, with Elon Musk at his side, already has significant consequences on our research partnerships, on our commercial partnerships,” Baptiste said in his remarkably pointed prepared remarks. “If we want to maintain our independence, ensure our security, and preserve our sovereignty, we must equip ourselves with the means for strategic autonomy, and space is an essential part of this.”
The problem? Ariane 6 and Vega C are costly, lack a path to reusability, and aren’t geared to match SpaceX’s blistering launch cadence. If Europe wants autonomous access to space, European taxpayers will have to pay a premium. Isar’s Spectrum also isn’t reusable, but European officials hope competition from new startups will produce fresh launch options, and perhaps stimulate an inspired response from Europe’s entrenched launch companies.
“In today’s geopolitical climate, our first test flight is about much more than a rocket launch: Space is one of the most critical platforms for our security, resilience and technological advancement,” Metzler said. “In the next days, Isar Aerospace will lay the foundations to regain much needed independent and competitive access to space from Europe.”
Tolker-Nielsen, in charge of ESA’s space transportation division, said this is the first of many steps for Europe to develop a thriving commercial launch sector.
“This launch is a milestone, which is very important,” he said. “It’s the first conclusion of all this work, so I will be looking carefully on that. I cross my fingers that it goes well.”
