Konstandin Tschaikovsky， the father of modern astronautics， first established in 1903 the laws of movement of the rockets. He was the first to define accurately the characteristics of the man — spacecraft capable of going out to the space and back. Space offers freedom， a source of life， which could one day leave the shadows behind.
