I know there have been some others who have had a chance to ask someone who knows how to read the Busa Kanji symbol what the exact translation is. Well, I had an opportunity to do that too. Was having lunch with 3 Japanese guys who are here on a business trip. I brought up the Hayabusa to see if they knew what I was talking about. After lunch I printed out the Kanji symbol and asked them what the exact meaning was.
He said the symbol was a Chinese Kanji, and the word "Hayabusa" was the pronunciation of the symbol and that it meant "falcon" in general, but could specifically mean "peregrine falcon". Then he gets out a piece of paper and draws the Chinese symbol for falcon in it's basic form, and also gets on his computer to verify ... and this is what the "raw" symbol looks like.

Now here's the way the symbol is used on the Busa.

You can see the similarities ... the Busa Kanji is all "fancy" looking of course.
From other translations posted on the board, I've heard it means "fast" or "powerful", etc ... but from what this guy is saying it's a direct translation to falcon or peregrine falcon. Makes the best sense to me.
