They tell legends of Mars, long ago.

Here is an extraordinary photograph of the Curiosity Rover, coming into land, taken by NASA’s Mars Reconnaissance Orbiter.

So there is life on Mars – at least, man-made life capable of taking a photo of another piece of man-made life!

Of course, the Doctor has had more than a few adventures with life on Mars – namely the Ice Warriors.

The Tenth Doctor got there just a bit too late, but the images of Mars from his story are in HD and a lot better quality than Curiosity’s have been so far!
