Since 2000, we have been designing a small nucleic acid sequencing instrument to send to Mars to detect and sequence DNA or RNA. The primary goal of this instrument will be to test the theory that DNA or RNA-based life may have exchanged between Earth and Mars, perhaps early in solar system evolution to carry life from one planet to the other. Our project will test the hypothesis on Mars by finding and sequencing DNA. Sequencing is necessary because it would confirm both the discovery of life and its deep branching relationship to Earth life, ruling out contamination.
