Japan Explores Phobos and Deimos with NASA Support

The Japan Aerospace Exploration Agency (JAXA) has launched its Martian Moons eXploration (MMX) mission, which aims to study the two moons of Mars, Phobos and Deimos, and return samples from Phobos. The mission is supported by NASA, which has provided two scientific instruments, including the MEGANE spectroscopy instrument and the Pneumatic collection mechanism. The MMX spacecraft is expected to arrive at Mars in August 2027 and return samples to Earth in 2031. Meanwhile, NASA is set to provide an update on its Artemis program on October 23, which may shed light on the progress of the mission to return American astronauts to the lunar surface.
