Without a protective magnetic field, anyone living on the Red Planet would have to protect themselves from the harmful radiation from the Sun that we, on Earth, are shielded from.

Now, the European Space Agency (Esa) has released a series of pictures revealing its latest fascinating geological feature – a giant channel created by ancient mega-floods more than 3 billion years ago.
