In a significant step forward for international space cooperation, NASA and Japan have inked a groundbreaking agreement that promises to shape the future of lunar exploration. This collaboration is not just a testament to the enduring partnership between the two nations but also a strategic move to advance sustainable human presence on the Moon.

The Agreement

On April 9, 2024, NASA Administrator Bill Nelson and Japan’s Minister of Education, Culture, Sports, Science and Technology, Masahito Moriyama, came together at NASA Headquarters in Washington to sign an historic agreement. The agreement outlines that Japan will design, develop, and operate a pressurized rover for both crewed and uncrewed missions on the Moon's surface. In return, NASA will provide the launch and delivery of the rover to the Moon, along with two opportunities for Japanese astronauts to travel to the lunar surface.
“The quest for the stars is led by nations that explore the cosmos openly, in peace, and together. This is true for the United States and Japan under the leadership of President Biden and Prime Minister Kishida,” said Nelson. “America no longer will walk on the Moon alone. With this new rover, we will uncover groundbreaking discoveries on the lunar surface that will benefit humanity and inspire the Artemis Generation.”

The arrangement falls under the “Framework Agreement Between the Government of Japan and the Government of the United States of America for Cooperation in Space Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies, For Peaceful Purposes,” which was signed in January 2023 and recognizes the nations’ mutual interest in peaceful exploration.

The framework agreement facilitates a broad swath of joint activities between the countries, including space science, Earth science, space operations and exploration, aeronautical science and technology, space technology, space transportation, safety, and mission assurance, and much more. In addition to the agreement for lunar surface exploration, the partners will build on the framework agreement with future agreements for Japan’s participation in NASA’s Dragonfly mission and the Nancy Grace Roman Space Telescope. The U.S. and Japan also intend to collaborate on JAXA’s Next-generation Solar-observing Satellite, SOLAR-C, which will investigate the mysteries of solar atmospheres by conducting observations of ultraviolet radiation from the Sun.


A Pressurized Rover for Extended Missions

The pressurized lunar rover is a game-changer for space exploration. It is intended to enable astronauts to travel farther and work for longer periods on the lunar surface, serving as a mobile habitat and laboratory. The rover will accommodate two astronauts for up to 30 days, allowing them to traverse the area near the lunar South Pole. “The pressurized rover will be a powerful contribution to the overall Artemis architecture as Japan and the U.S. go hand in hand with international and industry partners to the lunar surface and beyond,” said Hiroshi Yamakawa, JAXA (Japan Aerospace Exploration Agency) President. “JAXA is ready to assist MEXT and push this forward with our science and technological expertise to establish sustainable human presence on the Moon.”
NASA plans to utilize this rover on Artemis VII and subsequent missions, expecting it to have an operational lifespan of approximately 10 years.

Japanese Astronaut on the Moon

In this historic announcement, President Biden and Prime Minister Kishida shared the goal for a Japanese national to be the first non-American astronaut to land on the Moon on a future Artemis mission, provided that certain benchmarks are achieved. Under the Gateway Implementing Arrangement signed in 2022, NASA will provide an opportunity for a Japanese astronaut to serve as a Gateway crew member on a future Artemis mission and Japan will provide Gateway’s environmental control and life support systems and cargo transportation. This marks a significant milestone in space exploration history, as until now, only American astronauts have walked on the Moon during Apollo missions.

The Significance of the Agreement

Through Artemis, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon, make new scientific discoveries, and explore more of the lunar surface than ever before for the benefit of all.

This agreement is more than just a technical collaboration; it represents a commitment to peaceful exploration and the sharing of knowledge and resources. The pressurized rover will enable groundbreaking discoveries on the lunar surface that will benefit humanity and inspire future generations of explorers.

The signing of the agreement between NASA and Japan is a momentous occasion that heralds a new era of lunar exploration. It signifies a collaborative spirit and a shared vision for the future of space exploration. As we look forward to the achievements this partnership will bring, one thing is clear: the journey to the stars is not a solitary one but a path we walk together with our international partners.
