Tokyo, Japan - Space Data Inc. (Headquarters: Minato-ku, Tokyo; CEO: Koyo Sato, hereinafter "Space Data") and KDDI Corporation (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Makoto Takahashi, hereinafter "KDDI") will conduct a demonstration (hereinafter "the Demonstration") of robotic operations inside the Virtual International Space Station (hereinafter "Virtual ISS"), which was jointly developed with the Japan Aerospace Exploration Agency (hereinafter "JAXA"). This demonstration will take place from April 2025 to October 2025.

In preparation for this Demonstration, Space Data and KDDI have developed a technology (hereinafter "the Technology") that enables robotic movements inside the Virtual ISS in response to the same operational commands used for JAXA's Int-Ball2, a space robot currently operating on the real ISS.

Through this Demonstration, the companies will simulate and replicate the behavior of space robots within the Virtual ISS and compare their movements to those of actual robots in the real ISS using identical operational commands. By leveraging environmental data, including imagery and gravitational conditions obtained from the real ISS, the companies aim to enhance the accuracy of the Technology and improve the fidelity of the Virtual ISS. This will enable more comprehensive validation in the development and design phases of spacecraft and robots, significantly reducing development costs and improving space station operations through increased robotic utilization.

Additionally, from March 3 to March 6, 2025, Space Data and KDDI will showcase the Virtual ISS at MWC Barcelona 2025, the world's largest mobile technology exhibition in Barcelona, Spain. Partner companies will have the opportunity to experience the Virtual ISS, evaluate its effectiveness, and provide feedback for potential feature enhancements.

■Background

In April 2024, the Japanese government announced the establishment of a 1 trillion yen ($6.8 billion) Space Strategy Fund, emphasizing the growing importance of the space industry. The global space economy is projected to reach $1 trillion by 2040, creating new business opportunities for private companies. However, space remains a challenging frontier due to its extreme conditions-including microgravity, vacuum, and space radiation-as well as the high costs and uncertainties associated with space business development.

Space Data is committed to democratizing space through digital technology, making it as accessible as the internet. To achieve this, the company is developing a digital twin of space, allowing anyone to participate in space development. The Virtual ISS replicates the ISS with high-precision 3D spatial data and physical environment simulations. It is expected to be utilized in space robotics development, astronaut training, and space station environmental monitoring. Currently, it is available for free worldwide on Steam, the largest PC gaming platform, targeting gamers and educational institutions.

KDDI launched the MUGENLABO UNIVERSE program on May 30, 2024, fostering co-creation between startups and enterprises to leverage space technology for solving global challenges. Through this program, KDDI supports Space Data in expanding the user base for its simulation platform, providing computational resources, and offering financial assistance to facilitate commercialization.

■Details of the Demonstration

The Demonstration will recreate JAXA's Int-Ball2 space robot inside the Virtual ISS, allowing it to operate based on real ISS commands using the newly developed Technology. This will enable high-fidelity testing and validation of robotic systems within the Virtual ISS before deployment to the real ISS.

The behavior of the virtual robot in the Virtual ISS will be compared with that of the actual robot in the real ISS, evaluating the Technology's accuracy in replicating ISS environmental conditions. Data collected from the real ISS will be utilized to further improve the precision of the Virtual ISS.

The Demonstration will be conducted using JAXA's "Kibo" Utilization Program for commercial applications.
The high-precision Virtual ISS developed through this initiative will be provided to startups and enterprises via the MUGENLABO UNIVERSE program, enabling companies to test their space robots and infrastructure in a digital environment. Additionally, the companies plan to develop the Virtual ISS into a space experience platform, expanding its applications beyond research and development.

Schedule Phase 1: Compare operation and physics (~2025.6), Phase 2: Compare operation (2025.6~2025.8), Phase 3: Compare physics (2025.8~2025.10)
