Splendid meditation by Mark Anderson on the meaning of the Mars mission.

As you are no doubt aware, at 1:38 a.m. this morning, NASA and the Jet Propulsion Laboratory/Caltech succeeded in landing a one-ton rover named Curiosity on the surface of Mars.  This effort required years of scientific, technical and engineering preparation, resulting in a novel multi-stage process for getting heavy equipment onto the red planet, rife with steps which, if any failed, would likely cause mission failure.

The landing occurred without a single problem, including minutes during the critical last phases of the flight when the spacecraft was out of communications with Earth and ran autonomously.

While this effort will no doubt have a great impact in improving our knowledge of the Mars geology and surface, including habitability for future human missions, and perhaps information on past life in the targeted crater, there is a deeper meaning to this effort:

Science is reality.

At a time when a large and increasing fraction of the U.S. population does not “believe in” science (i.e., objectively provable reality) – or, worse, has bought into the idea that science is just one choice on the reality menu – NASA has again given concrete reason to understand that science works, and that science is not an option, not a theory, not a menu item, but instead represents the finest efforts of human minds in understanding, and addressing, objective reality.

Those on Earth who currently think that science is a political football should take note: not only are you endangering your own reputation, you are endangering the welfare of your constituents, and today, of the planet itself.

Any person or party which mocks science should be considered for what he or it is: a threat to the welfare and future of us all.  Under the influence of political propagandists, misled religious zealots, and truly dangerous television and radio empires (such as Fox (Not) News and Rush Limbaugh), too many people today have been led to believe that science is in some way an option to opinion.

Science is as optional as gravity.  Ignorance is the only real option.
