Konstantin Tsiolkovsky (1857-1935) is a man whose ideas made space exploration possible. In the 1910s he has already proven that it’s not impossible to send some kind of operated apparatus into space, also he calculated the speed and conditions of such travel. His ideas were too ahead of their time and he met a little support. He was producing different projects of aerostats, aeronats and dirigibles trying to find the one that would fit his calculations. He had to publish the project using his own money in his native town of Kaluga and send brochures out to scientific societies and individual scientists. This brochure is one of the early projects of Tsiolkovsky.
The first book edition of the main work of Konstantin Tsiolkovsky, dedicated to the theory of jet propulsion, where he derived the equation of motion of a rocket as a body with variable mass, expressed ideas about automatic flight control using a hydroscopic device, about the possibility of using sunlight to orient the rocket, predicted the phenomenon of weightlessness , expressed the idea of creating near-earth orbital stations, theoretically substantiated the possibility of interplanetary flights using a rocket.
The works under same titles were published in periodicals in 1903 and 1911-12, in which Tsiolkovsky has defended the similar ideas. Later in 1926 another edition appeared. One of the characteristics of Tsiolkovsky’s bibliography is that every new edition he has prepared he always altered the text, adding new data, sometimes the editions with the same titles differ completely, as his scientific narrative developed.
The copy of this edition with autographs of the Russian-American team of astronauts of Soyuz-Apollo 1975 is located in the The Museum of Cosmonautics in Moscow. It has been signed by them in space on their mission.
