I love the idea of somebody some day getting to Mars and reading the message: “To those, who visit here, we wish a safe journey and the Joy of Discovery.” A weary traveler reading a hopeful message from home.
You should head over and read the rest of the speech. Bill Nye is a good guy.
By the way, while you’re on Mars, stroll by The Spirit, Opportunity, or Curiosity Mars rovers. Each is fitted with a photometric calibration target, a small sundial that serves as a test pattern for their cameras. Look closely. Engraved on each are these words: “To those, who visit here, we wish a safe journey and the Joy of Discovery.” The joy of knowing: that’s science; that’s what drives us. It brings out the best in us — and makes our species worthy of the future.
