A spacecraft from Japan embarked on a mission to Mars to explore its enigmatic moons and retrieve samples on Tuesday. This groundbreaking endeavor, involving five of the world’s space agencies, aims to land a robotic prospector and a rover on Phobos, one of Mars’s two tiny moons.
The Japan Aerospace Exploration Agency spearheaded the ambitious sampling mission, launching the spacecraft from Tanegashima Island’s main spaceport in the early morning. An hour after liftoff, officials confirmed the successful separation of the spacecraft from the rocket’s upper stage, prompting celebrations among flight controllers.
While NASA has landed nine spacecraft on Mars in the last five decades and China achieved a touchdown in 2021, no previous missions have explored Phobos or its companion Deimos, nor has anyone retrieved samples from Mars or its moons. If successful, samples containing dust, soil, and rocks from Phobos are expected to reach Earth in 2031.
“There’s a lot of adrenaline and excitement,” shared NASA astrophysicist Tom Statler, emphasizing the significance of the mission. Japan’s prior experience with two successful asteroid sample returns positions them favorably for this mission.
The spacecraft, named MMX (Martian Moons Exploration), has a price tag of $812 million and is set to reach Mars by late next summer. It will rendezvous with Phobos and deploy the French-German rover, Idefix, named after a character from the Asterix comics. Idefix, about the size of a microwave oven, will autonomously land on Phobos and act as a safety scout for 100 days.
After exploring Phobos, the lander will spend two hours collecting material before departing for Earth. The ultimate goal is to decipher the origins of Mars’s moons and potentially shed light on the formation of planetary systems and the possibility of life elsewhere.
Despite past challenges faced by other space agencies in Mars missions, the collaborative effort aims to unlock the mysteries surrounding Mars’s moons. The quest for knowledge extends beyond national borders, as China and NASA plan their own sample return missions, with Japan and China aiming to bring back samples by 2031.
Financially backed by multiple agencies, including NASA, the French Space Agency, the German Space Agency, and the European Space Agency, the mission signifies a significant investment in space exploration and discovery.
