Keith Cowing thinks that “Everyone@NASA Should Have A Facebook Page” which I agree. In fact, I think what he is thinking is similar to what I have said: “Engineers, please write blog or diary“.

Qian Xuesen (钱学森)
The news that Qian Xuesen died on October 31 created a shock wave in China, but the wave didn’t seem to reach the other end of the Pacific ocean. If one search Google news on Qian Xuesen, there are only 228 results (as of Nov 2, 2009). But if one search 钱学森, there are 5,389 results. One of them was from LA Time: “Qian Xuesen dies at 98; rocket scientist helped establish Jet Propulsion Laboratory. NASA didn’t say a word. Cal Tech had few. I asked a few space engineers. None of them know about the news. One CFD expert said to me that he never saw Qian’s photo.

The story about Wan Hu (Wan Hoo, 万虎) was a legend first described by American author Herbert S. Zim in his book “Rockets and Jets” in 1945. Since then, Wan has been considered as the world’s first recorded “astronaut”. But there has not been any Chinese source that confirmed the legend. Recently, I found a story about Tsien Hsue-shen (Qian Xuesen, 钱学森) from a Chinese literature in which Tsien told a story to young scientists that he learned from his Chinese advisor Wang Shizhuo: “The Story of Wan Hu”. It has a lot of details about the first astronaut in history. It even claims that Chinese invented two stage rocket earlier than anyone else It happened in the year of 1465. Believe it or not. Here I translated the story to English:
