Space Data Releases "GROUND IMPACT SIMULATOR" to Visualize Impact and Damage from Landings and Collisions

Space Data, Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Kohei Sato; hereinafter "Space Data") is pleased to announce the release of "GROUND IMPACT SIMULATOR," a collision and explosion damage simulator that visualizes and estimates damage on the actual 3D map, ranging from explosions caused by warheads of missiles to asteroid impacts. This simulator is the second feature released under "AMATERASU," an AI platform responsible for operational command within the space AI platform "SpaceBrain." By simply clicking any point on the map, users can instantly estimate physical effects such as blast waves, heat, and earthquakes, as well as casualties, economic losses, and impacts on critical infrastructure.

Background: To Foresee the Consequences of Threats

In July 2026, Space Data launched "AMATERASU," an AI platform aiming to achieve superior commander decision-making in the operational command domain of the space AI platform "SpaceBrain." As its first feature, they released "AIR OPERATION SIMULATOR," which simulates aerial operations in a digital twin space replicating all of Japan. AMATERASU emphasizes the importance of foreseeing the consequences of actions or threats and creating a state where decisions can be made with a solid basis. To achieve this, it is essential to be able to share what would happen on the ground if an incoming object were to actually land or collide, with concrete numbers and maps.

Traditionally, estimating damage from explosions or celestial impacts required specialized analysis tools and knowledge, making it difficult for policymakers and general stakeholders to intuitively grasp the scale of the damage. GROUND IMPACT SIMULATOR addresses this challenge by providing damage estimations based on physical models published in celestial impact research, in a format that anyone can use on actual 3D city models.

Main Features of "GROUND IMPACT SIMULATOR"

1. Includes 71 Collision and Explosion Scenarios

It includes 14 types of natural celestial bodies, such as the Chelyabinsk meteor (2013) and the Tunguska event (1908), as well as 57 types of artificial explosions, ranging from conventional warheads of cruise missiles to large bombs, and historical large-scale explosion accidents and nuclear tests. It handles an energy range exceeding 10 orders of magnitude in TNT equivalent, allowing for comparison of damage differences based on the type and scale of warheads or explosives at the same location and under the same conditions.

2. One-Click Damage Estimation on Actual 3D Maps

Users can set the impact point by simply clicking on the map over satellite imagery and photorealistic 3D city models. Based on the explosion scale, it draws concentric circles for five damage levels, from total destruction to window breakage, and instantly calculates the released energy (TNT equivalent), altitude of airburst or crater size, fireball radius, and seismic magnitude. It also supports one-click navigation to major cities such as Tokyo, New York, and London.

3. Estimation of Human, Economic, and Infrastructure Damage

It retrieves population density around the impact point in real-time from public databases and calculates estimated casualties, affected population, economic losses, infrastructure damage rate, and overall severity (0-100). For Tokyo, it can visually confirm on the map whether critical infrastructure such as government agencies, defense-related facilities, power, communications, and water supply are within the damage range.

4. Visualization from Orbit to Ground Damage

It allows seamless switching between SpaceBrain's orbital view (displaying catalogs of satellites, debris, asteroids, etc.) and the ground view, enabling the handling of everything from orbital object monitoring to ground impact assessment on a single platform. It can also be utilized for planning preparations for asteroid impacts (planetary defense).

Anticipated Use Cases

Anticipated use cases include tabletop exercises for security and critical infrastructure protection, initial grasp of damage scale in disaster prevention and crisis management departments, sharing the magnitude of threats in education, public relations, and policy discussions, and planning for planetary defense. The physical calculations employ publicly available analysis models internationally used in celestial impact research, and it can be utilized for initial assessments and for forming common understanding among stakeholders as a simulation for approximate calculations and comparisons.

Future Prospects

Space Data will progressively enhance GROUND IMPACT SIMULATOR by incorporating more precise physical models that consider impact angles and atmospheric deceleration, reproducing chain reactions such as tsunamis and secondary fires, engineering damage estimations based on building data, global coverage of critical infrastructure information, and integration with orbital information of actual Near-Earth Objects (NEOs).

Furthermore, following simulations of aerial operations and impact damage, AMATERASU plans to expand its scope to simulations across land, sea, air, space, and cyber domains, from equipment level to strategic level. By establishing a foundation for perceiving threats from space to the ground on a planetary scale, Space Data aims to support decision-making in disaster prevention and defense fields and contribute to enhancing societal resilience.
