Europe must quickly get its own reusable rocket launcher to catch up to billionaire Elon Musk's dominant SpaceX, European Space Agency director Josef Aschbacher told AFP in an interview.

While the US company has an overwhelming lead in the booming space launch industry, a series of setbacks, including Russia's withdrawal of its rockets, left Europe without an independent way to blast its missions into space.

That year-long hiatus ended with the first launch of Europe's much-delayed Ariane 6 rocket in July 2024. But the system is not reusable, unlike SpaceX's Falcon 9 workhorse.

"We have to really catch up and make sure that we come to the market with a reusable launcher relatively fast," Aschbacher said at AFP's headquarters in Paris.

"We are on the right path" to getting this done, he added.

'Paradigm shift'
The ESA has already announced a shortlist of five European aerospace companies bidding to build the continent's first reusable rocket launch system.

That number will be narrowed down to two—or even one—at the agency's ministerial council in the German city of Bremen next month, Aschbacher said.

"Ariane 6 is an excellent rocket—it's very precise," Aschbacher said. "We have now had three launches," with two more expected before the year's end, he added.

Despite finally getting Ariane 6 and the new, smaller Vega C launcher off the ground, the ESA has decided on a "paradigm shift," Aschbacher said.
