ESA's Themis reusable rocket may miss its 2026 flight window
ESA says it isn't sure its Themis reusable-rocket demonstrator will complete its first hop test before the end of 2026.
what happened
ESA's director of space transportation, Géraldine Naja, said on Oct. 22 that she was not sure the agency could complete Themis's first hop test before the end of the year, citing approaching winter conditions at Sweden's Esrange Space Center, per European Spaceflight. ESA will make a go/no-go call by the end of November on whether to attempt the flight before winter shutdown; the program's development schedule requires a hop test before June 2027.
why it matters
Themis is ESA and ArianeGroup's demonstrator for vertical-landing, reusable first-stage technology, the capability SpaceX and Blue Origin already fly commercially and that European launch providers need to match on cost. Another slip, after successive wet-dress-rehearsal delays, pushes back when Europe gets real flight data on its own reusability approach, with a hard June 2027 program deadline now in view.
