With the Mars rover Perseverance and the small helicopter Ingenuity, Martian scientists learn new things about Mars every single day. Samples are collected and wind, weather and earthquakes are recorded. The geology of Mars is mapped in a large area and various craters are explored using the rover.

It turns out that even though Mars does not have a particularly strong magnetic field, the planet has a liquid core, which can make the whole thing shake once in a while.

Planetary scientist Morten Bo Madsen from the Niels Bohr Institute at the University of Copenhagen talks to Science Journalist Jens Degett from Science Stories.
