Finding life on Mars, or anywhere in the solar system, would be huge and would radically improve our ability to predict life elsewhere. If it's chemically different from earth life, that would revolutionize our knowledge of complex chemistries. If Mars life is chemically similar but independent of earth life, that would suggest that life tends to use common chemistry. If life on earth and mars has a common origin, that would tell us a lot about the early solar system. In short, N=2 doesn't sound great, but it is lightyears better than N=1.
