Japan is launching a Mars moon probe later today.

The Martian Moons eXploration mission is scheduled to launch at 2:41PM ET and, if successful, should return to Earth in 2031 carrying samples from Phobos. It’ll study both Phobos and Deimos on its journey to shed some light on how they came to exist, and hopefully provide new insights into both Mars and Earth.
