The realistic proposal of space travel goes back to Konstantin Tsiolkovsky.

Potočnik's book described geostationary satellites ( first put forward by Konstantin Tsiolkovsky ) and discussed communication between them and the ground using radio, but fell short of the idea of using satellites for mass broadcasting and as telecommunications relays ( developed by Arthur C. Clarke in his Wireless World article of 1945 ).
