Japan launches spacecraft to collect samples from Mars and return them by 2031

Japan has successfully launched its H3 rocket carrying the Mars Moons Probe (MMX), placing the spacecraft into its designated orbit and advancing the country’s ambitions in space exploration.

In a statement issued on October 20, Japan’s Minister of Education, Culture, Sports, Science and Technology welcomed the launch, describing it as an important step for the country’s space science and exploration capabilities.

The latest launch also strengthens the H3 rocket’s record of reliability. According to the minister, the rocket has completed three consecutive successful launches since its sixth launch in June, steadily building confidence in Japan’s next-generation launch vehicle.

The MMX spacecraft now begins its journey to explore the Martian system, carrying an ambitious scientific objective: to become the first mission in the world to return samples from the region of Mars and its moons. The mission is scheduled to bring the samples back to Earth in 2031.

Beyond its scientific goals, the mission is expected to contribute to the advancement of Japan’s space technology and deepen understanding of the Martian system. It also carries an educational ambition, with Japanese authorities hoping that the mission will spark curiosity among children and young people and encourage greater interest in science and technology.

The Ministry of Education, Culture, Sports, Science and Technology said it would continue working with the Japan Aerospace Exploration Agency (JAXA) and other organisations to advance space development and utilisation, while meeting public expectations for Japan’s space programme.

As the MMX spacecraft embarks on its long journey, the mission represents both a major scientific undertaking and an opportunity to inspire future generations to explore the frontiers of space.
