Mars Express: Triumph From Disaster

The video explores the Martian crustal dichotomy, a significant geological feature distinguishing Mars's northern and southern hemispheres. The northern hemisphere is smooth, while the southern is rugged and elevated. Two main hypotheses explain this: tectonic activity and a massive impact. Tectonic activity, driven by mantle plumes, may have thickened the southern crust. Alternatively, a collision with a Pluto-sized body could have smoothed the northern plains. Both theories are supported by magnetic field studies and geological evidence, but further research and rock samples are needed for confirmation.
