Colonization of Mars: A captivating book, from chapter to chapter. The plot makes us speculate on heterogeneous outcomes, but due to its mastery of the story and the eagerness it generates throughout the development, the writer surprises us with a completely unexpected ending. Colonization of Mars exposes humanity's dream of once again sailing through intimidating outer space. The dazzling fascination with exploring and the unindulgent challenge of conquering the cosmos, which is as infinite as it is mysterious, allows a feat that has always been in the collective imagination and has occupied the most ambitious projects of the main organizations and powers of the world to become a reality. Only this time it is done with the label: Next destination: RED PLANET. The author gives us, in the first instances, a timely introduction to the life of the characters. From then on, he achieves an exquisite communion between the technical preparations for this purpose, and the individual training of the crew, carried out to undertake an adventure unprecedented until then in the history of humanity. The reader will follow each character both in moments of technical instruction and physical preparation, as well as in the mental aspect of them. This work allows us to gain insight into key moments in the private life of each protagonist, which will reveal the motivation that each one had to venture on this unprecedented journey, but which also implies a journey of no return. In this way, it is not difficult to identify with some of the characters, since they are possessors of personalities that, regardless of the difference in cultures, always converge in the same interests that the common people share: love, fear, guilt, uncertainty, longings, hope. Feelings that unite us as a species and that, ultimately, are the lever and the engine that moves the world. That curiosity that takes man to the extreme of his possibilities and, sometimes, the unconsciousness that pushes him to the point of no return, as if he were falling vertiginously off a cliff. In the course of this work, we will accompany the crew step by step on their way to the shuttle as a springboard to the great leap of humanity. We will be there, expectant together with each fellow citizen who follows the bombastic spectacle from the comfort of their home, in every corner of the world, through the media. It is likely that it will lead us to speculate as to the possibility or not of achieving such a high goal. Surely, each one of us will adopt his favorite character and also the one we would like to take off the ship by the arm. In this way, we will become privileged spectators of the interplanetary big brother that the entire mission will end up becoming. Fasten your seatbelt and embark on this unprecedented journey, which will undoubtedly give you a lot to think about. And, above all, I suggest that you pay attention from beginning to end, because the final destination of this incredible journey will be far from what you are prepared to find.
