This material about astronautics was written for the 25th anniversary of space exploration and the 20th anniversary of the first manned flight into space. There was not enough material about astronautics at that time: only periodicals of newspapers and magazines, popular science films. Therefore, people attended such lectures with interest, listened carefully and asked questions. Just think: at the beginning of 1957, everything stated was fantasy, but from October of that year it became a reality, and space exploration proceeded at a gigantic pace. Nowadays, space flights have become commonplace, but the pioneers remain forever the first. This book is a reminder of events related to space exploration and the people who took an active part. And if the reader, after reading, becomes interested and becomes more deeply acquainted with this or that event, then the goal of this book has been achieved.
