Amateras Space Inc. Participates as a Collaborating Organization in JAXA Space Strategy Fund Phase 2: "Fundamental Technologies for Ensuring Safety in Manned Space Transportation Systems"

Amateras Space Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Taisei Hasumi) is pleased to announce that, along with Space NS Plan Inc., it will participate as a collaborating organization in a proposed theme adopted by the JAXA open call for the "Space Strategy Fund Phase 2 / Fundamental Technologies for Ensuring Safety in Manned Space Transportation Systems," with Space System Development Corporation serving as the representative organization. In this project, we will work on establishing domestic foundational technologies for ECLSS (Environmental Control and Life Support System), which plays a core role in the safety of manned space transportation. Through this, we aim to establish Japan's proprietary life support technologies and achieve high safety and reliability in future manned space activities.

■ Background and Objectives
Following the planned end of operations for the International Space Station (ISS) in 2030, Low Earth Orbit (LEO) is expected to transition to a new, private-sector-led space economy. However, for many years, there has been a continuous dependence on foreign technology for ECLSS, which is the core technology for safely transporting people to space, accommodating their stay, and returning them to Earth.

For Japan to play a proactive role in manned space exploration going forward, it is essential to become independent in life support technologies and establish a domestic technological foundation.

In this project, we will integrate the elemental technologies possessed by domestic companies to build a uniquely Japanese ECLSS foundational technology and establish safety and reliability. With the resolve to realize independent manned space transportation and habitation technologies for Japan, we aim to contribute to strengthening the international competitiveness of the next-generation space industry and creating a new space economy.

■ Overview of the Development Project
This project aims to establish foundational technologies for the "ECLSS for Pressurized Cabins," which is essential for the round-trip flights of manned spacecraft.

Our company will tackle this project focusing primarily on oxygen and nitrogen management technologies. This technology is a crucial foundational element not only for manned space transportation but also for future space habitation technologies and spacesuits, making it indispensable for future manned space development.

In addition to manufacturing and verifying a physical prototype, the BBM (Bread Board Model), we will utilize advanced analysis and simulation technologies to enable safety evaluations during emergencies where actual flight testing is extremely difficult, such as fires, rapid depressurization, and the generation of toxic gases. This will allow us to achieve both safety and reliability at a high level while keeping development costs and time in check, while promoting the development of the following key elemental technologies:

- Oxygen and nitrogen management technologies
- CO₂ and trace toxic gas removal technologies
- Integrated analysis and simulation technologies utilizing digital twins
- Microgravity-compatible space toilet systems

In the future, in addition to installing these systems on domestic manned space transportation systems, we will also look into supplying components for overseas commercial space stations, contributing to the strengthening of the international competitiveness of Japan's manned space development and space industry.
