Japan launched a spacecraft from Tanegashima Island on Tuesday, beginning a five-year mission aimed at exploring Mars' moons Phobos and Deimos. The \$578 million project, led by the Japan Aerospace Exploration Agency and involving five international space agencies, will attempt to land a rover named Idefix and collect samples from Phobos for return to Earth in 2031. This mission is the first of its kind, as no…

Japanese scientists are launching a mission to Mars's moons Phobos and Deimos using an unmanned probe called Martian Moons eXploration (MMX). Set to launch from Tanegashima Space Centre on Tuesday at 4:41 am local time, the MMX will orbit Phobos for up to three years before landing and collecting at least 10 grams of surface material. The mission aims to determine the origin of Mars's moons and explore their…

Japan has launched a space rocket from Tanegashima Space Centre to study Phobos, one of Mars's moons, for the first time. The five-year mission by the Japan Aerospace Exploration Agency (JAXA) aims to collect at least 10 grams of sand and rock samples from Phobos using a rover equipped with special landing legs to ensure stability on the low-gravity moon. Upon completion of its objectives in 2027, the MMX spacecraft…

Japan launched a spacecraft from Tanegashima Island on Tuesday as part of an ambitious five-year mission to explore Mars's moon Phobos and return samples to Earth by 2031. The $812 million project, known as MMX for Martian Moons Exploration, aims to land a robotic prospector and the French-German rover Idefix on Phobos, which is about 22 kilometers in diameter. If successful, this would be the first landing and…
