It is difficult to say what is impossible, for the dream of yesterday is the hope of today and the reality of tomorrow
Born in Worcester, Massachusetts. On October 19, 1899, I climbed a cherry tree and looked up at the sky. I imagined a device that could reach Mars. I climbed down a different person. Published A Method of Reaching Extreme Altitudes in 1919. The New York Times mocked me -- said rockets cannot work in a vacuum. Newton Third Law. On March 16, 1926, I launched the first liquid-fueled rocket. It flew for 2.5 seconds, reached 41 feet. Pathetic by any standard except it was the first time in history. Tip: The press will mock you. The military will ignore you. Do the work anyway. Document everything. Von Braun admitted his V-2s used my patents. NASA Goddard Space Flight Center is named for me. I never saw it.
