Early lifeEdit

Konstantin Tsiolkovsky was born on 17 September [O.S. 9 September] 1857 at Izhevskoye, Ryazan Governorate, Russian Empire. When he was 10, he had scarlet fever; because of that he had some problems with hearing. When he was 13, his mother died.[3] Due to the hearing problems, he was not admitted to the school, so he had to study by himself. He passed much of his time by reading books. Later, he became interested in mathematics and physics. As a teenager, he began to believe that space travel would possible.[1]

Tsiolkovsky spent three years attending a Moscow library, where Russian cosmism proponent (who supports the library) Nikolai Fyodorov worked. He later believed that living in space would make the human race immortal.[4]
