Static firing test of second stage motor of the Epsilon S Launch Vehicle
IHI Aerospace Co., Ltd. (hereinafter referred to as “IA”) has been developing the Epsilon S launch vehicle under the contract with the Japan Aerospace Exploration Agency (hereinafter referred to as “JAXA”).
On November 26, 2024, a static firing test of second stage motor was conducted at the Tanegashima Space Center. And during the test, unexpected combustion occurred, resulting in the explosion of the rocket motor. We regret that we were not able to meet the supportive expectations of all those concerned.
In order to ensure a reliable and prompt response to this issue, we set up a task force team headed by company’s director on the day of the test.
We will fully cooperate with JAXA, and proceed with the investigation of the cause and consideration of countermeasures for this issue, with full responsibility.

IHI Aerospace Co., Ltd. received a certificate of appreciation for the SLIM project from JAXA.
IHI Aerospace Co., Ltd. has been recognized for its contribution to the success of the "Small Lunar Landing Demonstrator (SLIM)" project, which demonstrates pinpoint landing technology on the moon, and has received a certificate of appreciation from the Japan Aerospace Exploration Agency (JAXA) in honor of its achievements. The certificate presentation ceremony was held on September 6th at IHI Aerospace headquarters in Tomioka City, Gunma Prefecture.
As interest in lunar utilization increases and water resource surveys are being planned, SLIM has taken on the challenge of developing precise landing technology for reaching scientifically interesting points on the moon.
SLIM is equipped with 12 thrusters developed and manufactured by IHI Aerospace. These thrusters respond to guidance control instructions based on information such as image matching, and play a crucial role in adjusting the attitude at the final landing near the moon surface, greatly contributing to the achievement of pinpoint lunar landing, i.e., "landing where we want to land."
The various technologies demonstrated by SLIM will be important elements supporting Japanese space exploration, such as the Mars Satellite Exploration Project (MMX) and the Lunar Polar Mission. We are very honored to have contributed to their success and to have demonstrated Japanese advanced technologies to the world.
IHI Aerospace will continue to contribute to the expansion of human activity areas and the development of Japanese space industry, responding to the growing global interest in space utilization, based on its reliable technological capabilities.

The companies have completed the preliminary design review and are planning to collaborate toward the critical design.
Since 2021, IHI Aerospace has been working with Japan Aerospace Exploration Agency on the development of an IDSS compliant active docking system. In the future, both active and passive docking systems are expected to become key technologies supporting not only Low Earth Orbit (LEO) activities but space exploration in the Artemis program [4].
Steve Berroth, Senior Vice President and General Manager of EarthSpace™ Systems at Sierra Space,
“Our mission at Sierra Space is to create a platform in space to benefit life on Earth. In realizing that vision, safety is paramount in everything we do in commercial space station design and development. IHI Aerospace shares this commitment and we are confident that the company’s passive docking system is the optimal technology to integrate into our platform.”Ryoichi Kidokoro, Senior Executive Officer of Kanematsu’s and COO of Motor Vehicles & Aerospace Division,
”We are delighted that the passive docking system manufactured by IHI Aerospace has been selected by Sierra Space, one of the leading space companies in the United States. Through this collaboration, we would like to accelerate to support on the export of Japanese manufacturers. We will continue our efforts to gain international recognition and trust for the superiority and high quality of space technology that Japanese companies have established so far, leading to the expansion of commercial space activities and the establishment of international cooperative relationships.”Kazumasa Goto, Board Director at IHI Aerospace
“We are very pleased that our passive docking system, which is being developed based on the mechanical system technology and heritage we have cultivated on the International Space Station and H-II Transfer Vehicle “KOUNOTORI” [5], has been adopted by Sierra Space for their space station technology. We believe this will also contribute to the future of benefit to humankind on the earth through our technology as a part of future commercial space stations.”About Sierra Space

IHI AEROSPACE's Hydrogen Fuel Cell Electric Propulsion System Technology Development Initiative adopted as NEDO’s Green Innovation Fund Projects to Accelerate Development of Zero-Emission Aircraft
IHI AEROSPACE Co., Ltd. announces today that the New Energy and Industrial Technology Development Organization (NEDO) has adopted a hydrogen fuel cell electric propulsion system technology development initiative of IHI AEROSPACE Co., Ltd. (Headquarters: Tomioka City, Gunma Prefecture, President: Fumiharu Namiki), as the Next-Generation Aircraft Development Project under NEDO’s Green Innovation Fund Projects (see note below).
Note: Green Innovation Fund Projects
NEDO established a \2.8 trillion Green Innovation Fund to ramp up efforts to achieve carbon neutrality by 2050, through structurally transforming the energy and industrial sectors and investing extensively in innovation. The fund will provide ongoing support to public and private sector entities collaborating to pursue ambitious and specific goals from R&D and demonstrations to social implementation of outcomes over the next 10 years. This assistance is primarily in 14 priority fields for which the Green Growth Strategy has formulated action plans.

For this project, IHI AEROSPACE will develop a four-megawatt-class hydrogen fuel cell electric propulsion system. This zero-emission setup would power an aircraft with more than 40 seats and feature a cruising duration of more than three hours. The University of Tokyo(President: Teruo Fujii) will partner in this development project, contributing with technical studies and international standardization efforts.
The project will run for approximately six years from FY 2024 to FY2029. IHI AEROSPACE will examine fundamental design of this zero-emission propulsion system which has fuel cell and hydrogen supply system at its core, as well as looking into the optimal layouts and specifications of each component, after which actual components will be developed. A critical goal will be to demonstrate the ability of the system to operate continuously for more than three hours through ground-based demonstration tests.
IHI AEROSPACE aims to leverage its extensive expertise in system integration for rockets and other space vehicles, its experience with liquid hydrogen, and its capabilities as the IHI Group’s aero engine manufacturer to develop an internationally competitive hydrogen fuel cell electric propulsion system. By combining these strengths, IHI AEROSPACE seeks to enter the market as a key provider of propulsion systems for decarbonized aircraft.
The IHI Group is committed to carbon neutrality by 2050, as part of which it will help to decarbonize aviation economically. It will accordingly step up efforts to commercialize this system, help electrify aircraft, innovate distinctive lightweight technologies, and develop synthetic fuels.
