Why it matters
Mars has two tiny moons that researchers note shouldn't exist, making their origins a mystery. The Japanese Aerospace Exploration Agency mission represents a once-in-a-lifetime chance to study these bodies directly. Bringing home material from Phobos could help scientists understand how the Martian system formed and evolved.
