88 years ago today, Robert Goddard launched the world's first liquid-fueled rocket. For space exploration, this was a moment akin to what the Wright brothers did at Kitty Hawk 23 years earlier. Goddard's rocket used gasoline and liquid oxygen and solved the problem of stability by the unique device of putting the engine at the top of the rocket instead of the bottom. Goddard would go on to make enormous strides in all areas of rocket technology. It's tragic that he didn't live to see the first satellites, but NASA's Goddard Space Flight Center is only one of many tributes maintained today to the father of liquid-fueled rocketry. Hats off, Dr. Goddard!
