What happened

Japan's space agency is leading a five-year uncrewed mission to collect samples from Phobos, one of Mars's two moons, and bring them back to Earth. The spacecraft, called the Martian Moons eXploration craft, lifted off on an H3 rocket before dawn from the Tanegashima Space Center in southwestern Japan. Its climax is planned for 2029, when it will attempt up to two landings on Phobos.

Why it matters

The mission would be the first to gather samples from Phobos and could be the first spacecraft to return from orbit around Mars. Scientists hope the samples will help explain how Mars acquired its two moons.
