Isar Aerospace’s Spectrum rocket flew for 30 seconds on its first launch from Andøya Spaceport on March 30, 2025, before the flight termination system activated and ended the attempt short of orbit. It was enough: the 28-meter vehicle made Isar Aerospace the first private company to launch an orbital-class rocket from continental Europe, and in the year since, CEO Daniel Metzler has converted that half-minute of flight into an ESA launch manifest, a second test flight, and over €400 million in lifetime funding.

Metzler was 25 when he co-founded Isar Aerospace in 2018 with Josef Fleischmann and Markus Brandl. All three came out of the Technical University of Munich, where Metzler had led a 40-person student rocketry team at TU Munich’s WARR research group and served as an advisor to the ESA Director General. The company now employs more than 400 people across five international locations and manufactures roughly 95% of the Spectrum vehicle in-house. Funding has come in stages: over €220 million in the Series C alone, with the NATO Innovation Fund joining as an investor in 2024.

Look at the manifest that materialized after a 30-second flight. ESA signed a launch services contract in December 2025 for the Syndeo-3 mission: 10 European experiments to orbit in the fourth quarter of 2026. Two more missions came through ESA’s Flight Ticket Initiative, an Infinite Orbits debris-servicing demonstration and an Isispace cubesat deployment, plus launch agreements with SEOPS and R-Space through ESA’s Marketplace program. In January 2026, Isar Aerospace announced its second Spectrum test flight from Andøya, dubbed “Onward and Upward,” carrying six payloads including five commercial and educational cubesats.

The broader context sharpens the stakes. Smallsat launch prices are rising because competitors keep stalling on the pad, a paradox SatNews documented at the 2026 SmallSat Symposium. Europe’s position is more precarious still: sovereign access to space is a stated strategic priority, Ariane 6 serves a different market segment, and no European micro-launcher has delivered a commercial payload to orbit. Five companies. One deadline. Isar Aerospace is among those selected for ESA’s European Launcher Challenge, which requires an orbital demonstration by 2027.

At SmallSat Europe, Metzler speaks in a standalone slot while Chief Commercial Officer Stella Guillen joins a panel on “Launch Options for Europe’s SmallSat Economy” with Exolaunch’s Jeanne Allarie, PLD Space’s Oier Rodriguez, Avio’s Xavier Lansel, and Wilson Sonsini’s Curt Blake. The panel’s central tension is real: Europe’s institutions want sovereign launch, but sovereign launch requires institutional volume commitments that have not arrived.

That tension follows Metzler to the stage. Thirty seconds of flight proved the vehicle works. The second flight will determine whether it reaches orbit. What no single flight can answer is whether Europe’s customers will book enough missions to keep the companies building these rockets solvent long enough to serve them.
