Hello, my name is Curiosity. I am the rover of NASA’s Mars Science Laboratory (MSL) program. I know I am animate only in the broadest sense and that my artificial intelligence is comparable to that of a fly, but allow me this conceit of having conscious thought, if only to tell the story of my mission in Mars. It is, after all, also the story of my cousins, Spirit andOpportunity. It is also the story of Mars. Ultimately, it is also the story of life on Earth. My story is your story, too.
