Japan's Martian Moons eXploration (MMX) probe will launch on October 20, aiming to collect samples from Phobos, one of Mars's moons. The mission may reveal how Mars and its moons formed, a key piece of knowledge in working out how the solar system was born.

Why it matters

The mission could unlock the origins of the solar system and life on Earth, providing crucial knowledge for future space exploration.

Imagine sending a robot to Mars to collect rocks and learn about the planet's history. That's basically what Japan is doing with its Martian Moons eXploration (MMX) probe. The robot will fly to Mars, collect rocks from one of the planet's moons, and then come back to Earth. This will help scientists learn more about how the solar system was formed and how life on Earth might have started.

Japan's Ambitious Mars Mission: Unlocking the Origins of the Solar System and Life on Earth

Japan's Martian Moons eXploration (MMX) probe is set to launch on October 20, marking a significant milestone in the country's space exploration endeavors. The uncrewed mission, a collaboration with U.S. and European space agencies as well as numerous universities and tech companies, aims to collect and bring back samples from one of Mars's moons, Phobos. This ambitious endeavor may help unlock the origins of the solar system and life on Earth, providing crucial knowledge for future space exploration.

The MMX probe will stay in Mars' orbit for around three years, during which time it will attempt to land on Phobos. The spacecraft will collect at least 10 grams of material from the surface of Phobos, while the rover IDEFIX will conduct surface observations. The spacecraft will also observe Deimos, another Mars moon, but without landing. A return capsule is meant to head back to Earth and land in Australia in 2031.

JAXA hopes that the mission will reveal how Mars and its moons formed, a key piece of knowledge in working out how the solar system was born. The mission will also explore the possibility of using Phobos as a 'natural space station' by establishing the technology required for a round trip to Mars — something 'essential for crewed Mars exploration.'

The MMX mission is a testament to Japan's commitment to space exploration and its desire to push the boundaries of human knowledge. With its cutting-edge technology and international collaborations, Japan is poised to make significant contributions to the field of space exploration and beyond.

Key points

  • Japan's Martian Moons eXploration (MMX) probe will launch on October 20.
  • The mission aims to collect samples from Phobos, one of Mars's moons.
  • The MMX probe will stay in Mars' orbit for around three years.
  • The mission will explore the possibility of using Phobos as a 'natural space station.'
The Upside

If the MMX mission is successful, it could lead to a better understanding of the origins of the solar system and life on Earth. This knowledge could be used to develop new technologies and strategies for future space exploration, including potential human missions to Mars.

The Downside

However, there are also risks associated with the MMX mission. For example, the spacecraft could experience technical difficulties or encounter unexpected obstacles during its journey to Mars. Additionally, the mission's reliance on international collaborations and complex technology could lead to delays or cancellations.
