Challenge Challenging new frontiers

Space exploration is a great challenge to expand humanity's sphere of activity and develop a new frontier.
JAMSS expands the experience and skills earned thru development and operation of the Japanese Experiment Module “Kibo” of the International Space Station (ISS) and engages in space exploration.

Exploration From the ISS to Space Exploration

Since its launch in 1998, ISS that orbits around the Earth has been operated as the frontline of manned space activities by humanity.
As the next stage for manned human activities, projects aimed at Moon and Mars exploration are ongoing, led by space agencies around the world.

The Artemis program by the United States aims to achieve manned Moon exploration by 2025, the first since the Apollo program of the 1960s and the 1970s.
Moreover, JAXA and Toyota Motor Corporation are conducting research on “LUNAR CRUISER”, a manned lunar rover, aimed to launch to the lunar surface in 2029.

JAMSS engages in various projects in order to contribute to space exploration for developing new frontiers, such as the Martian Moons eXploration (MMX) and Lunar Orbital Platform -Gateway.

Exploration from the ISS

mission-01 Lunar Orbital Platform-Gateway

Lunar Orbital Platform-Gateway is a space station whose purpose is to support manned activities on the lunar surface and to conduct technical verification toward deep space exploration, for instance of Mars, as a part of the Artemis program led by NASA.

Gateway consists of eight modules and robotic arms. For these, Japan is planned to contribute through providing batteries, environmental control/life support systems and logistics vehicle.

Maintenance of crew life is one of the highest priorities in the development of manned space systems. JAMSS contributes to the manned space exploration of the future by supporting development and integration of environmental control and life support systems of Gateway I-HAB (International Habitation), as well as by its safety evaluations, using the skills acquired through technical support of safety development assurance of “Kibo”.

mission-02 MMX (Martian Moons eXploration)

Martian Moons eXploration (MMX) is a mission to explore Martian moons in order to elucidate their origins, as well as the formation and evolution of Mars area.

MMX is a mission to explore Phobos and Deimos, both moons of Mars, and bring back samples from the surface of Phobos to Earth. The probe is to be launched in 2024, and it is scheduled to bring back the samples to Earth in 2029. This will be the first ever time that samples are brought back from Mars area.

Utilizing the small celestial body sample retrieval technology Japan is widely known for, it is the largest international joint exploration mission of Mars area led by Japan.

MMX (Martian Moons eXploration)

Since 2019, JAMSS has been conducting operation preparations for MMX, supporting the operation design of its overall system, including the probe’s bus system, mission equipment and ground system, in order to ensure the success of MMX’s mission for its entirety, from its launch to the retrieval of the samples to the Earth.

In addition, we are examining the training plan for the flight control staff of MMX, using our knowledge acquired during the training of the control staff of the ISS and Hayabusa2.

Lunar society Toward the realization of a lunar surface society

Space agencies around the world are promoting manned lunar surface exploration, and many companies are engaging with various projects aimed at the realization of a “lunar society”. In addition to participating in these manned lunar surface explorations, JAMSS promotes the expansion of commercial utilization of manned activities in low earth orbit, using the ISS and other facilities in order to move the activities toward the lunar surface and realize a “lunar society”. Moreover, many companies, in addition to governments and space agencies, are taking part in a wide range of studies toward the realization of a “lunar society” that contributes value back to Earth. JAMSS is also participating in several projects working toward the realization of a lunar society.

Future Connecting the future of humanity and space

Where do we want to go in 10 years, when the ISS comes to an end? The story titled "Connecting the future of humanity and space,” compiled last year, imagines for ourselves where we want to go, and gives words to this vision. Like the First Penguin, we will not shy away from new challenges, and we will turn this story into reality.

Connecting the future of humanity and space

Corporate mission Until today, and into the future
Operation of "Kibo" by JAMSS

"JAMSS is the number one in space safety." We are in the business of connecting humanity with space through the ultimate operation technology required in this extreme environment.
We are involved in the operation of “Kibo” and “Kounotori” at the International Space Station (ISS) program, training of astronauts and control staff, and realization of space experiments.

Service Bringing space closer to life

"JAMSS is the number one in space safety."
We contribute to the development of rich life on Earth through providing services based on the skills and knowhow acquired through training of astronauts and control staff, and the safety, reliability, and maintainability that we ensure in space experiments.
