The group flight of the Soviet spacecraft Vostok-3 and Vostok-4 with cosmonauts Andriyan Nikolaev and Pavel Popovich on board is the greatest achievement of modern science and technology, marking a new stage in the exploration of outer space. The book "The Path to Space is Open" by V. Bazykin and V. Komarov, published by our publishing house in 1961, contains materials for thematic evenings in the club dedicated to the achievements of astronautics and the first space flights of Yu. Gagarin and G. Titov in the history of mankind. This collection is, as it were, a continuation of this book. It tells about the life and studies of the heroes-cosmonauts A. Nikolaev and P. Popovich, provides new scientific data obtained as a result of a group flight; this includes poems and songs about Soviet cosmonauts. The final article by V. Komarov gives a detailed plan of the thematic evening. The bibliographic section will help you find the materials you need to prepare for lectures and conversations, and can also be used to organize a book-illustrative exhibition.
