Today, we’re going to discuss Mars – the planet, not the candy maker. Mars has held a cultural interest for the world for literally millenia, being named after the Roman god of war due to its red, angry color. In the late 1800’s, Mars fascination peaked again as research revealed what seemed to be artificial structures – leading to books such War of the Worlds and the Princess of Mars. And now, it seems as if Mars has taken the spotlight again. Curiosity currently wanders the planet, and my office in a much smaller form, NASA just verified that liquid water still flows on today’s Mars, intermittently at least, and the movie “The Martian” was just released, the first decent Mars movie in years.
