In Depth

Key Findings

Interstellar Technologies (IST), a leading Japanese space venture, has published an updated video showcasing the construction progress of ‘Launch Complex 1’ (LC1) at Hokkaido Spaceport. This facility is a critical infrastructure for IST, which previously achieved Japan’s first private space launch with its MOMO suborbital vehicle, and is now advancing towards commercial satellite launch services.

Technical Details

LC1 at Hokkaido Spaceport is designed to accommodate the launch of IST’s medium to large-scale rockets, comprising payload integration facilities, propellant storage, and launch pads. The facility aims to meet the growing demand for commercial satellite launches and strengthen the domestic space industry ecosystem. IST’s vision is to provide high-frequency, low-cost space transportation services, and LC1 is foundational to realizing this objective.

Background & Context

IST has been at the forefront of Japan’s private space development, achieving the country’s first private space arrival with its MOMO suborbital rocket in 2019. The company has steadily expanded its operations, including progressing through stage gates in JAXA’s Space Strategy Fund program for satellite businesses. Hokkaido Spaceport is emerging as a significant spaceport in Asia, aiming to attract launch demands from both domestic and international space companies. Such privately-led infrastructure development is essential for revitalizing space activities in the commercial sector.

Strategic Significance & Outlook

The completion and operationalization of LC1 will mark the full-scale launch of IST’s satellite launch services, particularly in communication satellite-related ventures. This will enable IST to accommodate larger rockets and diverse payloads, offering competitive launch opportunities to clients globally. Hokkaido Spaceport, as a hub for private space development, is expected to further accelerate the growth of Japan’s overall space industry and enhance its presence in the international space race. This development forms a cornerstone for Japan’s ambition in the global space sector.
