Outlook --Addendum --PostscriptFor all being interested in astronautics, this translation of Hermann Oberth's classic work is a truly historic event. Readers will be impressed with this extraordinary pioneer and his incredible achievement. In a relatively short work of 1923, Hermann Oberth laid down the mathematical laws governing rocketry and spaceflight, and he offered practical design considerations based on those laws.Interplanetary voyagesSpace flightSpace flightRockets (Aeronautics)Interplanetary voyages.Space flight.Space flight.Rockets (Aeronautics)629.47/52629.4Oberth Hermann6715DE-B1597DE-B1597BOOK9910966281503321The Rocket into Planetary Space4450310UNINA
