EU extends SALTO deadline again as Themis hop test slips
The European Commission pushed the SALTO reusable-launcher project's deadline to Dec. 31, 2026, as Themis's first hop test slips again.
what happened
The European Commission extended the completion deadline for the SALTO (reuSable strAtegic space Launcher Technologies & Operations) project to December 31, 2026, per the EU's own project database, cited directly by European Spaceflight. SALTO is a 42.8 million euro EU research project led by ArianeGroup, layered onto the ESA-managed Themis reusable-rocket demonstrator, funding its first two low-altitude hop tests. It is the latest in a series of extensions pushing the deadline back from the original November 2025 date. Themis arrived at Sweden's Esrange facility on June 27, 2025, and completed an initial wet dress rehearsal on July 23, 2025, using liquid nitrogen to simulate cryogenic conditions; the next scheduled milestone is a hot-fire test of the vehicle's single Prometheus engine. ESA's own public 2026 highlights calendar had briefly listed the first hop test as completed in the second quarter of 2026, a discrepancy European Spaceflight flagged against the project's own extension filing.
why it matters
Europe's reusable-launch roadmap keeps slipping against the cost-reuse economics SpaceX and newer entrants like Rocket Factory Augsburg and Isar Aerospace are already chasing; each SALTO extension pushes back when ArianeGroup can credibly demonstrate vertical-landing technology toward a future Ariane successor, a schedule gap that matters to European institutional and commercial customers weighing launch-cost trajectories.
