AstroX Secures 1.8 Billion Yen in Funding for Rockoon Rocket Development

AstroX Secures Funding for Groundbreaking Rockoon Technology



AstroX, a burgeoning private space startup based in Minamisoma, Fukushima, has successfully raised a total of 1.8 billion yen in funding through a Series A round, including 1.36 billion yen in equity financing led by Alpha Corporation and 440 million yen in debt financing from multiple financial institutions. This significant investment will allow AstroX to accelerate the development of its satellite launch vehicle using the innovative Rockoon method, aiming to reach outer space by 2026.

The Vision Behind AstroX


Founded in May 2022, AstroX is committed to reclaiming Japan's status as a leader in space development. As the global space industry experiences rapid growth, it is expected to exceed approximately 160 trillion yen by 2040, with satellite services being a primary driver in this expansion. However, Japan currently faces a severe shortage of rockets capable of launching satellites, relying almost entirely on foreign rockets for its small satellite launches. This gap in launch opportunities poses a significant challenge to Japan's space development endeavors.

AstroX aims to overcome this issue and transform the space industry into one of Japan's major sectors by implementing a cost-effective, high-frequency, and responsive launch method through the Rockoon system, which utilizes balloons to launch rockets from high altitudes.

Accelerating Development Post-Funding


Following a successful test of their hybrid rocket at an altitude of 10 km in November 2024, AstroX is diligently progressing with various technical evaluations, including ground combustion tests of their small hybrid rocket engine, and wind tunnel tests aimed at verifying posture control devices. The funding acquired will expedite the development of the Rockoon system, contributing towards the practical application of this pioneering technology in space transport.

Seeking Passionate Individuals in Aerospace


AstroX is actively looking for talented individuals to join its rocket development efforts. Those who resonate with the company's mission or have even a slight interest in space development are encouraged to reach out.
