STAR-1 :
POWERING SIRIUS LAUNCHER
STAR-1
STAR-1 is produced 100% in house using Laser Powder Bed Fusion (L-PBF), a state-of-the-art 3D printing technique.
This approach boosts performance and speeds up development, helping us push the limits of spaceflight.
Each first stage will be equipped with 9 STAR-1 engines, and the second stage with a single engine. For SIRIUS 13 and SIRIUS 15, each booster will also be fitted with 9 engines.
PROPULSION
STAR-1 fueled by liquid methane and liquid oxygen, it generates a vacuum thrust of 55 kN.
STAR-1 TESTS
DECEMBER 2023
DLR-Lampolshausen - P8
60 seconds at full thrust power
OCTOBER 2024
DLR-Lampolshausen - P8
120 seconds at full thrust power
APRIL 2025
DLR-Lampolshausen - P8
140 seconds at full thrust power
