For a long time experts thought that not much was going on inside Mars, but researchers at the Australian National University made their finding after combing through data from NASA's InSight Mars lander. New research has revealed previously undetected quakes beneath the Martian surface, which experts think is proof that it hosts a sea of magma in its mantle. Mars has very little in the way of a magnetic field, which suggests a lack of internal activity. However, when NASA's InSight lander arrived in November 2018 and started 'taking Mars' pulse', it found that the planet was rumbling. 'Understanding Mars' magnetic field, how it evolved, and at which stage of the planet's history it stopped is obviously important for future missions and is critical if scientists one day hope to establish human life on Mars.'
