Here’s a teaser from an article I’m writing on Mars. It should be coming out soon. When I sell the rights to Sony Pictures, I’m going to ask that Russell Crowe play Mars. Is there any other logical choice?
Two Visions of Mars
Before he became the Roman god of war, Mars lived a quieter life as the protector of farms, crops, and animals. He was beloved by Romans as the father of Romulus; this made him the celestial father of the Roman people. Mars began to change as the Roman Empire changed. While farmers continued to look to him for protection, so did the imperial legions which left the Italian peninsula on expeditions of conquest.
In the first century BCE, therefore, Mars represented two things at once. He was the giver of life, the guardian of agriculture. He was also the blood-stained warrior, the defender of soldiers marching at the frontiers of the known world. While Romans may have been united in their love of Mars, they looked to him for different reasons.
Despite the change from god to planet, Mars continues to mean different things for different people. On one hand, it is an archive of the past, a planetary laboratory where scientists seek answers about the history of the solar system and the origins of life. On the other, it is the landscape of the future, the next human frontier, the first real step out of our planetary cradle.
In principle, these different visions of Mars – as science laboratory and human frontier – are complementary. On the science side, mission planners have long defended robotic expeditions for their value in paving the way for human exploration. Mariner, Viking, and Pathfinder all found justification as the trailblazers of human missions. Most recently, the Jet Propulsion Laboratory defended its uber-Rover, the Mars Scientific Laboratory, as a mission that will “prove techniques that will contribute to human landing systems”

Advocates of human spaceflight also defend the compatibility of human exploration and science, often on the grounds that humans are more effective in doing science than remotely-operated probes. As Mars Society president Robert Zubrin declares, Martian science “is a job for humans” [Launius & McCurdy, Robots in Space, 21].
In practice, however, the divide over Mars runs deep. Many space scientists express growing frustration with human space flight, which they view as an expensive distraction from scientific exploration. Lower costs, improvements in computer design and miniaturization, and the proven durability of Martian probes have encouraged their faith in robotic science and made arguments for sending astronauts to Mars less compelling.
By contrast, many supporters of human missions to Mars believe that the focus on science and robotic exploration has become too narrow, ignoring the deeper meanings of exploration, its capacity to inspire people today, and shape the societies of tomorrow. For those looking to place boots on Mars, NASA seems to be drifting in a Sargasso Sea of underfunded programs and policy revisions, never able to chart its course for the New World….
