Overview
- Isar Aerospace launched its two-stage Spectrum rocket from Andøya Spaceport and reported reaching orbit on Saturday, September 5, 2026, completing stage separation, second-stage burns, and deployment of five cubesats and an in‑flight experiment.
- The company says the flight met its qualification and challenge milestones after Spectrum crossed the 100 km Kármán line and completed circularization burns, and Isar is working with customers to confirm the on‑orbit status of the payloads.
- Spectrum's second flight follows a March 2025 failure that an internal investigation traced to an unintended vent‑valve opening and loss of attitude control; Isar applied software and margin changes and carried out integrated static fires and wet dress rehearsals before relaunching.
- ESA supported the mission through its Boost! programme and counts the flight as meeting the European Launcher Challenge milestone, a boost for efforts to create independent European access to space for civil and security needs.
- Isar plans to scale production, expand launch sites and fulfill a growing manifest for small and medium satellites, a development that could cut Europe’s reliance on non‑European launch providers and reshape the regional launch market.
