"On October 4, 1957, the era of exploration of interplanetary space began with the launch of the Soviet artificial Earth satellite. After this significant date, only three and a half years passed, and man entered the stellar path. Will you ever forget the source of life on our planet - incredibly generous a bluish-white Sun, completely unlike the Earth's. So far, only a few have seen it. But I am sure that in the future dozens or even hundreds of earthlings will see it, and these will be people of different professions and citizens of different countries. All of them will penetrate into the secrets of the universe. with a single thought about the good of humanity. The path to the stars is not easy for both these people and those who equip them with technology... Without breaking away from the real possibilities of science and technology, but only slightly intruding into the realm of fantasy, I try to imagine how one behind the other, giant steps are erected leading man into the universe." Yuri Gagarin, February 20, 1968
