Isar Aerospace reaches orbit on second Spectrum flight, opening new European launch option

Isar Aerospace's Spectrum rocket reached orbit and deployed payloads on only its second flight, the Munich-based company said. The launcher uses kerosene and liquid oxygen propulsion and is designed to carry up to 1,000 kg to sun-synchronous orbit. Isar secured €200 million in ESA Launcher Challenge contracts in August 2026 alongside Rocket Factory Augsburg.

Why it matters: Two flights, orbit achieved — Isar now has the fastest ramp in European small-launch history, which matters because Ariane 6 remains supply-constrained and the continent still lacks sovereign rapid-reconstitution capacity.
