Dr. Arthur Pendleton — Lead of the Xenobiological Life Division at Luna Research Dome 4 and author of Life in the Solar System and Beyond: What We Know, What We Don’t, and Why It Matters (2153, Luna University Press). Spent thirty years cataloguing non-terrestrial life for the Xenobiology Archive. His book’s introduction frames five open questions: the chirality problem (nine D-chiral worlds, no exceptions), Mars’s ambiguous biosignatures (possibly “a world that almost made it”), convergent evolution from shared D-chiral ancestry, the endosymbiosis wall (no confirmed mitochondrial-equivalent event in any non-terrestrial biosphere), and the implications of n=2 intelligence. In March 2167 he told The Peer Review that the Everett protocell result at Utopia closed the Mars question in exactly the direction he had hoped and feared: “Mars did not fail to have life. Mars succeeded at proto-life. That is a different failure, and a more interesting one.” The same broadcast reported the confirmation of Europa’s primary producer, Lithophagus radiolyticus, standing his endosymbiosis wall against its strongest test yet — a complete food chain, pre-endosymbiotic top to bottom.
