German launch provider Isar Aerospace successfully conducted the second test flight of its Spectrum orbital rocket on September 5, 2026. The mission, designated "Onward and Upward," carried six payloads to orbit as part of the European Space Agency's "Boost!" educational program. The payload manifest included five CubeSats developed by European universities—CyBEEsat from TU Berlin, TriSat-S from the University of Maribor, Platform 6 from EnduroSat, FramSat-1 from NTNU, and SpaceTeamSat1 from TU Wien Space Team—alongside a non-separable experiment called "Let It Go" from Dcubed.

The launch occurred from Andøya Spaceport in northern Norway, a site increasingly utilized for small-lift-vehicle operations in Europe. Spectrum is a three-stage, solid-fueled launch vehicle designed to deliver small satellites to low Earth orbit. The mission followed approximately eighteen months after Spectrum's inaugural flight, which experienced a failure during its first test in early 2025.

The successful completion of this second test flight represents a significant milestone for Isar Aerospace's development program. The mission demonstrated the vehicle's capability to reliably reach orbit and deploy multiple educational payloads, validating key systems and paving the way for future commercial operations supporting Europe's small-satellite launch ambitions.
