The meteorite who was too magnetic

Somewhere in the vast landscape of the Sahara desert, a man stumbles upon an unusual kind of rock. After being passed around from dealers to collectors, the rock finds itself in a research laboratory. The rock is confused and does not remember where it comes from. A researcher invites the rock to a space journey, leading it back to its origins, planet Mars.

Meteors and meteorites have always fascinated people, but a particular aspect of these space rocks remains enigmatic to most people: their magnetic records. This comic illustrates how planetary magnetic fields are generated, how rocks record them and how the magnetic record of rocks helps scientists decipher how planets form and evolve over time.
