About the book: 1963 / "The terrible seconds dragged on unbearably. The spaceship was rushing headlong, perhaps into the very center of the flow of penetrating radiation, from which no protection could save. Death was approaching with oppressive inevitability...” Resourcefulness and courage more than once helped the astronauts avoid terrible danger. Will they help again? Will the astronauts have the strength to endure the trials of an unfamiliar strange world discovered not so far from Earth? This book tells about the courage, inquisitive mind and strong friendship of five astronauts.
