OUR SERVICES

SIRIUS : A range of reusable launchers suited for small and mid sized satellites

Sirius range is developped from innovative, reliable, and sustainable technological choices...

  • The Sirius range enables operators of small satellites to benefit from the same launch services as those offered to operators of heavy satellites.

    A few months before launch, we organize a pairing meeting in order to choose the most suitable launcher. 

    In this way, we enable the small satellite industry to benefit from fast, precise orbiting of their satellites.

  • Our range of launchers allows us to tailor our approach to each customer, ensuring a fill rate of over 85%.

    We use a maximum of space-qualified COTS components (Components on the Shelf) to reduce development and achieve a competitive launch cost.

  • Conscious of our responsibility, we are striving to improve our environmental footprint and are committed to provide for a more sustainable access to space. 

     

    Sirius Space Services prioritizes the reuse of its launcher components, with the aim of being 100% reusable in the long term.

    We use environmentally-friendly LOX / LCH4 propellants to propulse our launchers.

  • The Metal Additive Manufacturing process, deeply embedded in the company's DNA since its inception, provides both design freedom and the ability to enhance performance, reduce mass, and streamline assembly processes. 

    This manufacturing process, ingrained in Sirius' expertise, is employed to produce 85% of our STAR-1 engine.

    METAL ADDITIVE MANUFACTURING

  • To expand SIRIUS range, we're using the first stage of Sirius 1 as a booster, adding 2 boosters for Sirius 13 and 4 boosters for Sirius 15.

    A COMMON BASE

    To propel our launchers, the STAR-1 engine has a nozzle extension adapted to the 1st and 2nd stages.

OUR ENGINE

STAR-1: An innovative engine to propel our launchers

STAR 1 is our flight scale rocket engine, conceived to power Sirius’ launcher family.​

Powered by liquid methane and liquid oxygen, it generates a vacuum thrust of 55kN.​

STAR 1 core is composed by a nickel-based superalloy injection head and a copper alloy combustion chamber, both produced with Laser Powder Bed Fusion (L-PBF) process.​​
