Spectrum: Europe’s First Commercial Rocket Reaches Orbit

On the crisp morning of September 5, 2026, a thin plume of white flame rose from the frozen runway of Andøya Spaceport, deep inside the Arctic Circle. It was the moment Europe had been waiting for: a privately built rocket, conceived in a Munich workshop, finally finding its way into orbit.

The vehicle was called Spectrum, a 28‑metre tall, two‑metre wide launch system that runs on liquid oxygen and propane. Propane may sound like the fuel you’d use for a backyard grill, but it’s actually cheap, easy to store and burns cleaner than the kerosene that powers most launchers today. For a company hoping to reuse parts of its rocket, that cleanliness matters.

Built almost entirely in‑house at Isar Aerospace’s new factory near Munich, Spectrum packs nine engines on its first stage and a single engine on the second. Together they can lift about a tonne of payload to low‑Earth orbit, or roughly 700 kg into a polar trajectory – a perfect fit for the modest‑sized cubesats that were on board.

The payload consisted of five cubesats, each no bigger than a shoebox, coming from a mix of universities and commercial partners across Europe: research labs in Slovenia, Berlin and Vienna, a Norwegian student team, plus commercial hardware from Bulgaria and Germany. When the rocket completed its sequence – stage separation, second‑stage burn, fairing jettison, circularisation burn – the tiny satellites were released and began their own quiet journey around the planet.

It wasn’t all smooth sailing the first time. In March 2025, Spectrum’s maiden flight lasted a heartbreaking 30 seconds before a vent‑valve opened at the wrong moment, sending the vehicle tumbling into the sea. The failure was a harsh lesson, but the team used it to refine the design and their launch procedures.

Seventeen months later, the second flight flew the full script without a hitch. The moment the rocket cleared the launch pad, it felt like a small victory for European commercial space – a sector that has long been dominated by government rockets launched from French Guiana. Now, Europe has a home‑grown, private launcher that can operate from its own soil.

Isar Aerospace’s new manufacturing line is built for speed – up to 40 rockets a year – because hitting orbit once is only half the battle. Consistently delivering payloads on schedule is what will turn this into a sustainable business, and the successful launch of Spectrum is the first real proof that the company can do it.

So, while the world still watches the big players, a modest German startup has quietly nudged Europe a step closer to a more diverse, commercial space future.
