Today is the 50th anniversary of the first space flight by a human. If that person had been Alan Shepard, the United States would be having a national celebration. Instead, the national celebration is in Russia. The rest of the world, to varying degrees (unless you’re in a war, recovering from an earthquake and tsunami, or a cast member of the “Jersey Shore”) are paying tribute. One of the best is being featured on YouTube – a documentary that was released online today. The story of Yuri Gagarin is a great one, and Gizmodo has a nice piece about him and his historic achievement. Below is the documentary: First Orbit.
