Edgar Mitchell was the first man to set foot on the Moon after the near disastrous Apollo 13 mission. Their trip to the Moon re-assured a rather nervous country that space travel could be fairly safe. Within a few years after their return to the Moon, the Apollo mission was cancelled without fanfare and no man has stepped on the Moon since. The Mercury, Gemini, and Apollo astronauts have always been my biggest idols. Nothing to me defined guts more than leaving your planet in a tiny, tiny, metal can.
