Mesange is equipped with advanced technologies developed by Opus Aerospace, including innovations in structure, avionics, and propulsion. These systems have been refined by the company and are designed to be adaptable for use in future missions like Sterne, following the logic of modular space components.

Mesange suborbital launch will take place from the Guiana Space Center near Kourou, French Guiana, a key site for European space missions. This launch highlights the center's role in advancing space exploration.

Mesange is a suborbital testbed launch vehicle that builds on OPUS Aerospace's legacy technologies, paving the way for the development of the Sterne launcher & space systems.
