Historic MMX Mars Moon Mission Prepares for Launch
Japan and world space agencies are ready to launch the historic MMX mission to explore Mars' moon Phobos and bring soil samples safely back to Earth.
Space scientists in Japan have completed thrilling preparations for an extraordinary journey into deep space. The Japan Aerospace Exploration Agency, widely known as JAXA, is gearing up for a historic mars moon mission called the Martian Moons eXploration, or MMX for short. The spacecraft will blast off from the Yoshinobu Launch Complex at the Tanegashima Space Center in Japan.
This daring robotic voyage will travel millions of kilometres to visit Phobos, one of the two rocky companions circling the Red Planet. Lift-off is scheduled for 19 October 2026 aboard an H3 rocket on Flight Number 10. The mission marks the start of an ambitious five-year effort to gather pieces of an alien world and deliver them straight back to Earth.
What happened?
The MMX programme brings together leading space scientists from across our planet. While JAXA leads the expedition, teams from NASA in the United States, the European Space Agency, France’s CNES, and Germany’s DLR are all working together. Their shared goal is to make MMX the very first space mission in history to collect soil from Phobos and return it safely home.
Following lift-off, the probe will spend ten months speeding across interplanetary space. It is scheduled to enter Martian orbit in August 2027 and begin circling Phobos in September 2027. Phobos is famous among astronomers because it looks like a giant, lumpy potato floating silently in the dark sky!
To study this strange world up close, the spacecraft carries a compact rover named Idefix, jointly created by French and German engineers. This tough little rover will roll across the low-gravity surface of Phobos. Next, the main mothership will land on Phobos to collect at least 10 grams of pristine regolith using JAXA’s special core drill and a pneumatic sampler provided by NASA.
Before heading home, the spacecraft will also carry out detailed flybys of Mars’ second moon, Deimos, and observe the Martian atmosphere. In late 2030, the return capsule will begin its homeward flight, with plans to touch down in the Woomera desert in Australia in 2031.
Why does it matter to you?
If you have ever gazed at the twinkling night sky from your terrace in India, this journey will spark your imagination! Scientists have spent decades debating where the two potato-shaped moons of Mars came from. Some researchers think they are wandering asteroids trapped by Mars’ gravity, while others believe they are shattered debris thrown out by a giant crash on Mars long ago.
By bringing pieces of Phobos back to Earth, scientists will finally be able to solve this cosmic puzzle. Studying these moons will also help humans understand how our Solar System formed and prepare future astronauts for real voyages to Mars. One day, you could be part of the international scientific team studying these alien rocks!
Words to know
- Regolith: the layer of loose rocky soil, broken pebbles, and dust resting on the surface of a moon or planet.
- Interplanetary: travelling or situated in the vast space that lies between different planets.
- Low gravity: a weak downward pulling force that allows objects to float or bounce around very easily.
- Pneumatic: using the force of pressurized air or gas to move objects or collect materials.
Did you know?
Mars has two tiny, potato-shaped moons called Phobos and Deimos, and Phobos orbits so closely that it zooms around Mars three times every single day!
Think about it
If you were an engineer designing the rover Idefix to explore a bouncy, low-gravity moon, what cool features would you add? What other space mysteries would you like countries around the world to investigate together?
