・Interstellar Technologies has secured four customers (Ocullospace, Wolfpack, DALRO Aerospace, Osaka Metropolitan University and, Tokyo City University) for the first flight of its orbital launch vehicle, ZERO.
・Securing commercial and institutional payloads for a first launch is an extraordinary milestone in the space industry, showcasing the strong trust and shared ambition among Interstellar and its partners.

Tokyo (Japan), August 12, 2025 – Interstellar Technologies (“Interstellar”),a leading space infrastructure company, is proud to announce the 5 secured customers to fly aboard the first flight of orbital launch vehicle ZERO. This milestone mission will include CubeSats from four organizations, Ocullospace, Wolfpack, Osaka Metropolitan University and Tokyo City University, and a fifth participant, DALRO Aerospace, that will supply the separation system for the universities’ CubeSats. These 5 customers have already signed each a Launch Service Agreement with Interstellar. This launch highlights Interstellar’s growing global partnerships and commitment to expanding access to orbit.

Interstellar, a pioneer in private space transportation in Japan, was the first domestic private company to reach space with its suborbital vehicle, MOMO. The company is currently developing ZERO, an orbital vehicle designed to launch small satellites in response to the global shortage of launch capacity and in alignment with the Japanese government’s goal to enhance domestic launch capabilities .

Securing commercial and institutional payloads for an inaugural orbital launch is a rare achievement in the space industry, where first flights are typically reserved for internal testing. The presence of external customers on ZERO’s first mission showcases the forward-thinking mindset of the participating organizations, who are taking this opportunity to test and validate their own technologies in space. Their participation is a testament to the strength of the space industry and its shared drive to take on new challenges in expanding access to orbit.

Their decision to join this flight reflects a deep spirit of collaboration. This mission represents a unique alliance of student-built CubeSats, pioneering startups, and visionary institutions, all united by a common goal: to reach space.
