Japan launched the Martian Moons eXploration (MMX) spacecraft from Tanegashima Space Center on Tuesday, marking the start of a mission to collect samples from Phobos, one of Mars' two moons.

The MMX spacecraft, led by the Japan Aerospace Exploration Agency (JAXA) in partnership with NASA, the European Space Agency, and the French and German space agencies, will arrive at Mars in August 2027.

Upon arrival, MMX will use a device called a Pneumatic Sampler to collect at least 10 grams of soil from Phobos. The spacecraft is equipped with 13 scientific instruments, including NASA’s MEGANE instrument, which will help determine the elemental composition of Phobos' surface.

The mission aims to understand the origins of Phobos and Deimos, Mars' two moons. Scientists believe that meteor impacts on Mars could have blasted material up off the planet's surface, some of which may have landed on Phobos.

Planetary scientist Michael Zolensky of NASA’s Johnson Space Center in Houston said, “A few grams of sample are going to be a real bonanza for scientists.”

The MMX spacecraft will not orbit Phobos but will use a quasi-satellite orbit, circling Mars in a path that keeps it near Phobos.

The mission's science and return samples will complement decades of Mars exploration and help inform future discoveries, including potential crewed missions to Mars.

Scientists hope that Martian material collected from Phobos will shed light on the origins of the solar system and life on Earth.

The mission begins with a journey lasting several months before MMX reaches Mars in 2027, with the spacecraft expected to return to Earth in 2031 with samples from Phobos.

The MMX project manager, Yasuhiro Kawakatsu, said samples from Phobos will provide useful data for scientists to consider using a Martian moon as a base for a future manned mission to the planet.

What this adds

The mission's launch was confirmed by multiple outlets, including ABC News, Aerospace Global News, and The Guardian.

The spacecraft will deploy a lander, touch down, and collect soil and small pebbles from Phobos.

The mission's success could provide insights into the formation of the Martian system and the origins of materials essential for life on Earth.
