StellaCradle Inc. (Headquarters: Kobe City, Hyogo Prefecture) is pleased to announce its research and development concept for "StellaCradle," an artificial gravity technology for the space habitation era, within the scope that can be disclosed.
This concept aims to demonstrate and socially implement "cradle-style artificial gravity" which reduces discomfort by addressing human body load, living comfort, space medicine, space construction, and human-centered design in closed environments as crucial issues during long-term space stays.
Taking this announcement as an opportunity, our company will promote demonstration collaboration, joint research, and business co-creation with space-related companies, construction companies, universities/research institutions, local governments, and stakeholders in the medical and ergonomics fields.

■ Background of the Announcement
Space development is transitioning from an era of rockets, satellites, communications, and transportation to a stage where the focus is on "how to create environments for people to stay, work, and live in space for extended periods."
It is known that microgravity environments cause various effects on the human body, including bones, muscles, circulatory system, sense of balance, and immune function. For the future expansion of lunar bases, space stations, space hotels, and orbital research facilities, designing a safe and comfortable gravity environment for humans is considered a crucial challenge.
StellaCradle Inc. addresses this challenge by focusing not merely on "generating artificial gravity through rotation" but on "human-centered artificial gravity environments" designed to include the direction of gravity perceived by humans, the posture of living spaces, and discomfort during movement.

■ What is StellaCradle?
"StellaCradle" is a research and development concept for artificial gravity technology towards the space habitation era.
The "cradle-style artificial gravity" that our company is researching and developing focuses on a structure where the living space follows the effective direction of gravity while utilizing centrifugal force generated by rotation.
In conventional rotating artificial gravity, discomfort and physical burden associated with movement can be problematic when people move within the rotating environment.
StellaCradle aims to achieve an artificial gravity environment suitable for long-term stays by aligning the living space itself with a direction closer to human sensory perception.
This announcement is limited to the scope of a research and development concept that can be disclosed. Detailed mechanism, design information, and verification data will be progressively released through individual discussions from the perspectives of intellectual property protection and safety confirmation.

■ Key Areas StellaCradle Aims For
1. Space Habitation Field
Aims to improve living comfort in lunar bases, orbital facilities, space hotels, space stations, etc.
2. Space Medicine and Space Life Sciences Field
Aims to evaluate the effects of microgravity environments on the human body, conduct research in variable gravity environments, and apply it to future space medical centers.
3. Space Construction and Space Infrastructure Field
Considers its utilization as gravity environment technology to support long-term work, stays, training, and construction activities in space, on the Moon, and Mars.
4. Ground Demonstration, Education, and Experience Field
Promotes applications in ground small-scale models, visualization experiments, space education, science experiences, closed-environment training, and next-generation human resource development.
5. Integration with Disaster Prevention and Crisis Management Field
In collaboration with the World Disaster Prevention Center, our company is also working on disaster prevention and mitigation, emergency communication, and rescue support technologies, aiming to create new social infrastructure through the fusion of space technology and terrestrial disaster prevention technology.
