Overview
- Isar's Spectrum, which lifted off Sept. 5, 2026, reached orbit on its second mission and reported the deployment of five cubesats plus an in‑flight experiment.
- The vehicle cleared key test points including transiting MaxQ, completing main-engine cutoff and stage separation, igniting the second stage, crossing the Kármán line, jettisoning the fairing, performing a circularization burn, and reporting spacecraft separation.
- Payload teams and Isar say they are working to confirm the health and operations of the five small satellites after the live video feed ended about ten minutes into the flight when the vehicle exceeded the broadcast range.
- The flight follows an investigation of Spectrum’s March 2025 failure that traced the loss of attitude control to an unintended vent valve opening and led Isar to change software, raise system margins, and carry out integrated static‑fire and wet dress rehearsals.
- Isar and ESA frame the result as a step toward European autonomous launch capacity, with Isar moving to serial production of additional Spectrum vehicles and planning a second launch site in Canada that could deepen competition and reduce reliance on non‑European rockets.
