Researchers now hoped to find traces of this era inside the planet and answers to the question of why Mars changed so drastically. What they then actually discovered shows that Mars is still alive.

What does this mean now exactly also in view of the future settlement of the planet? And could Mars become a living world again through clever terraforming?
