The MMX mission, which aims to collect and return to Earth more than 10 grams of sample from Phobos, one of Mars’ moons, has a key objective of investigating whether Phobos (and its sibling moon Deimos) are capture asteroids or were formed through a giant impact event. In this presentation, I will show how the isotopic composition of these samples can provide valuable insights into the origin and history of Phobos, and will make a comparison with what we have learned about the origin of our Moon using similar methods.
