The German startup successfully launched its Spectrum rocket from Norway, marking a milestone for European commercial spaceflight.
Key facts
- •The Spectrum rocket reached orbit approximately seven minutes after its 4:12 pm EST liftoff from Andøya Spaceport.
- •Isar Aerospace has raised roughly $1 billion in private funding and employs nearly 500 people.
- •The rocket carried five small CubeSats and a non-separating technology experiment into orbit.
- •The German Space Agency (DLR) previously awarded the company $13 million in 2021 to support rocket development.
- •Spectrum is the first rocket built predominantly in Germany to reach orbit.
Isar Aerospace successfully launched its two-stage Spectrum rocket into low-Earth orbit on Saturday from the Andøya Spaceport in northern Norway. The mission, which carried five CubeSats and a technology experiment, makes Isar the first European company to reach orbit with a fully commercial launch vehicle. The rocket lifted off at 4:12 pm EST and reached orbit seven minutes later.
By the numbers
Company Origins and Development
Founded in 2018 by Daniel Metzler, Josef Fleischmann, and Markus Brandl, Isar Aerospace emerged from a student workshop at the Technical University of Munich. The company has raised approximately $1 billion in private financing and employs nearly 500 people, making it the most well-capitalized private launch company in Europe. The development of the Spectrum rocket took eight years, following a path similar to other commercial space startups.
Technical Specifications and Mission Success
The 92-foot-tall Spectrum rocket utilizes nine Aquila main engines burning propane and liquid oxygen, generating over 150,000 pounds of thrust. It is designed to carry up to one metric ton of payload into low-Earth orbit. This successful flight, dubbed "Onward and Upward," followed a failed test flight in March 2025, where the vehicle spun out of control shortly after liftoff due to a vent valve issue.
Strategic Importance for Europe
The success of the mission is viewed by European officials as a step toward strategic autonomy in space, reducing reliance on non-European launch providers. Unlike incumbent providers like Arianespace and Avio, which rely on government-funded procurement models, Isar operates on a privately-funded basis. The European Space Agency recently awarded Isar a $230 million contract to support its development as part of the European Launcher Challenge.
