will launch to the Mars moon Phobos today

Japan successfully launched a groundbreaking spacecraft, the Martian Moons eXploration (MMX) probe, from the Tanegashima Space Center on Tuesday at 4:41am local time. This ambitious mission, a collaboration between Japan, the United States, Europe, and various universities and tech companies, aims to become the first to retrieve samples from one of Mars' moons, Phobos.

If the spacecraft accomplishes its objectives, it will arrive near Mars by August next year and spend three years orbiting Phobos before landing to collect at least 10 grams of surface material. The mission, which marks the first round trip to Mars' Martian region, holds great potential in unraveling the origins of the Solar System and the emergence of life on Earth.

Two main theories - "the giant impact hypothesis" and "the capture hypothesis" - attempt to explain the formation of Mars and its two moons. If successful, the MMX mission will not only provide valuable insights into the Red Planet's history but also pave the way for future human exploration. The probe will also study Deimos, Mars' other moon, although it will not land on it.

Along its journey, the MMX mission will explore the possibility of using Phobos as a natural space station, an essential requirement for crewed Mars exploration.
