There they will find that some of its craters have been renamed to honour the Apollo 8 mission, the first to orbit our natural satellite 50 years ago.

Mars has to resign to the idea that earthlings have figured out how to grow plants on it. Not even perchlorates can stop them. And last but not least, New Horizons is unstoppable going towards Ultima Thule.
