Japan launches mission to explore Mars' moons and bring back samples

A Japanese spacecraft rocketed towards Mars on Tuesday on an unprecedented quest to explore its mysterious moons and bring back samples. Five of the world’s space agencies joined forces for the five-year mission that will attempt to land a robotic prospector plus a rover on Phobos, the larger and closer of Mars’ two pint-sized moons.

Officials declared success an hour later when the spacecraft separated as planned from the rocket's upper stage. Flight controllers burst into applause and jumped to their feet, shaking hands and embracing. While NASA has successfully landed nine spacecraft on Mars over the past 50 years and China scored a 2021 touchdown, no one has ever ventured onto Phobos or its sidekick Deimos.

If successful, bits of dust, soil and rocks from Phobos will arrive on Earth in 2031. “There’s a lot of adrenaline and a lot of excitement and a lot of wow,” said NASA astrophysicist Tom Statler, who’s involved with the project.
