Isar Aerospace to Launch Spectrum Rocket from Norway on January 21 After Previous Failure
Isar Aerospace plans to attempt the second test flight of its Spectrum rocket on January 21, 2026, from the Andøya Space Center in Norway. The launch window opens at 21:00 CET, subject to weather and safety conditions.
This follows a failed inaugural flight on March 20, 2025. The Spectrum rocket, designed for small and medium satellite transport, stands 28 meters tall and 2 meters in diameter, powered by a combination of liquid oxygen and propane.
It can carry payloads of up to 1,000 kilograms to low Earth orbit or 700 kilograms to a sun-synchronous orbit. The mission will include five satellites, including TU Berlin's CyBEEsat for testing the RACCOON Operating System, and the ROSI-1 experiment from the University of Potsdam to evaluate perovskite solar cells in space conditions.
