About the book: year / Mid-twenty-first century. A planet has been discovered in the orbit of the star closest to the Sun, on which, with a high degree of probability, life is present. To study this planet, an international expedition of five astronauts is sent to it. Humanity places special hope on it, since growing demographic and environmental problems threaten the very existence of earthly civilization in the long term. The start is successful. The main and backup systems of the ship do not record any failures either during launch or during acceleration. The astronauts are put into a state of artificial sleep for the next four years. But when they wake up, it becomes obvious that something happened during their flight that none of them could have even foreseen..
