PARIS (Reuters) – The European Space Agency (ESA) has started preliminary technical discussions with SpaceX, the company of billionaire Elon Musk, which could lead to the temporary use of its launchers after the war in Ukraine blocked the Western access to Russian Soyuz rockets.
Arianespace’s American competitor is with Japan and India among the top candidates to solve this temporary problem, but the final choice will depend on the timetable for the Ariane 6 rocket, which has not yet been finalized.
“I would say that we are discussing two and a half options. One is SpaceX, that’s clear. Another is maybe Japan,” ESA director general Josef Aschbacher told Reuters.
“Japan is awaiting the maiden flight of its next-generation rocket. Another option could be India,” he added. “I would say SpaceX is the most operational of them.”
Josef Aschbacher clarified that discussions were at a preliminary stage and that any solution would be temporary.
“Of course we have to make sure they fit. It’s not like jumping on a bus,” he said. For example, the interface between the satellite and the launch vehicle must be appropriate and the payload must not be compromised by unusual vibrations during takeoff.
“We are looking at this technical compatibility, but we haven’t requested a commercial offer yet. We just want to make sure that this is a (viable) option to make a decision on requesting a commercial offer,” said Josef. Aschbacher.
SpaceX did not respond to a request for comment.
Until now, Europe has depended on the Italian Vega rocket for small payloads, the Russian Soyuz rocket for medium payloads and the Ariane 5 rocket for heavy missions. The next generation of Vega C debuted last month and the new Ariane 6 has been delayed until next year.
According to Josef Aschbacher, the Ariane 6 schedule will be clearer in October. ESA will then be able to finalize a rescue plan which will be presented to the ministers of the Agency’s 22 member countries in November.
According to the agency’s director, the invasion of Ukraine demonstrated that Europe’s cooperation strategy with Russia in gas supplies and in other areas, including space, was not working more.
“It was a wake-up call, we have been too dependent on Russia… We really need to strengthen our European capabilities and independence.”
He, however, downplayed the possibility of Russia fulfilling its promise to withdraw from the International Space Station (ISS).
