On Saturday, September 5, 2026, Munich-based launch service provider Isar Aerospace successfully achieved orbital insertion with its Spectrum launch vehicle during its inaugural test flight, designated “Onward and Upward.”
Liftoff occurred from the Andøya Spaceport in Nordmela, Norway, marking the first orbital launch by a privately developed European launch vehicle from continental Europe.
Launch Vehicle Parameters and Payload Integration
The Spectrum launch vehicle is a two-stage liquid-fueled rocket designed specifically to deploy small and medium-class satellites into low Earth orbit (LEO) and sun-synchronous orbits (SSO). The rocket uses propane and liquid oxygen (LOX) propellants across both stages, utilizing nine Aquila engines on the first stage and a single vacuum-optimized Aquila engine on the upper stage.
During the inaugural flight, the vehicle successfully executed second-stage shutdown, orbital insertion, and payload separation protocols:
- Payload Manifest: Deployed five small satellites and one technology demonstration experiment into a 500-kilometer orbit.
- Payload Capacity: Engineered to carry up to 1,000 kilograms to low Earth orbit and up to 700 kilograms to sun-synchronous orbit.
- Additively Manufactured Hardware: Features 3D-printed engine combustion chambers and turbopumps manufactured at Isar Aerospace’s integration facilities in Munich.
Institutional Context and Spaceport Infrastructure
The orbital flight validates the commercial readiness of Andøya Spaceport, an orbital launch facility located on the Norwegian island of Andøya. Isar Aerospace secured exclusive multi-year access to Launch Pad 1 at Andøya to support sovereign European launch capacity for commercial, civil, and defense satellite operators.
The mission addresses ongoing European launch access constraints following the retirement of Ariane 5 and the transition to Ariane 6, providing European smallsat operators with dedicated domestic orbital access.
Operational Roadmap and Production Scaling
Following telemetry verification from the maiden orbital flight, Isar Aerospace will integrate its second Spectrum vehicle at its Munich manufacturing center. The company plans to scale production and flight operations toward a commercial launch cadence from Andøya Spaceport to serve commercial constellation customers across Europe and international markets.
