KONSTANTIN TSIOLKOVSKY: (1857 - 1935) Pioneering Russian scientist and rocket designer who laid out the basic principles of modern space flight. Outstanding, early, very rare A.Ms.S. on rocket travel, signed "K. Tsiolkovsky" in the text, 2pp. 8vo., [n.p., n.d. but ca. 1920-1930], comprising two full pages of notes on his work on rocket travel, and adorned with six drawings showing a prototypical airlock's operation, depicting an astronaut entering the airlock, interior door closing, depressurization, and the opening of the exterior hatch to space. Untranslated, but the text undoubtedly describes the operations of the airlock. A very rare document, in very good condition.
