I often tell my children that generations pass and centuries pass, but it seems that the sense of curiosity in people does not change. Sure, our environment changes and technology changes, but people are still human. We still carry the spirit and adventure of those we read about in history, the Bible, the Greek plays, the discoveries of Columbus, and the exploration of the Americas. Likewise, astronauts love to explore, and they feel very confident, focused, and determined about it.
