SUMMARY:Astrobiology and the Torridonian
DESCRIPTION:Mars is thought to have been habitable early throughout its history (>3 billion years\nago)\, when it sustained an atmosphere and stable bodies of liquid water at its\nsurface. Although the surface of Mars is now entirely inhospitable\, traces of a\nputative biosphere may be archived within its sedimentary rock record. The potential\nof finding fossilised traces of life on Mars has been the driving force behind its\nexploration for several decades\, and continues with the NASA Curiosity and\nPerseverance rovers\, which are currently exploring Gale and Jezero craters. A\nrecent discovery by Perseverance of organic matter associated with reduced mineral\nphases in the Neretva Vallis river channel has stimulated new interest in the\npossibility of a Martian biosphere\, and these materials have been sampled for\neventual return to Earth.\nUntil we achieve Mars Sample Return\, developing hypotheses about Mars’ early\nhabitable history requires us to harness understanding of similar localities here on\nEarth; we term such setting ‘planetary field analogues’. In this talk\, I will discuss the\nimportance of planetary field analogues for understanding ancient Martian\nenvironments\, and consider how exceptionally well-preserved fossiliferous\nsedimentary rocks from the Torridon Group of NW Scotland provide insights into\npotential habitable environments on early Mars and the types of biosignatures for\nwhich we might search following the sophisticated laboratory analysis of Martian\nsamples brought to Earth in the future. \nKeyron Hickman Lewis\, GSG Grant Awardee\, School of Natural Sciences\, Birkbeck College\, London \nKeyron has been a Research Assistant (2019–2020) \, CNRS Orléans (France) and Università di Bologna (Italy) \nAurora Research Fellow (2021–2024)\, Natural History Museum\, London \nResearch Fellow (2024–2024) \, Imperial College London \nand from 2024 a Lecturer in Planetary Exploration\, Birkbeck\, University of London \nHis research interests are \nCo-evolution of Earth and Life in the Precambrian: can we constrain the emergence of major microbial metabolisms throughout the Precambrian and their relationship with changing sedimentary environments and ocean chemistry? \nModern analogues of ancient ecosystems: How can we use extreme planetary field analogues most effectively to explain geological and ecological aspects of environments on the early Earth and Mars? \nTechnique development: How can we harness non-traditional and emerging instrumentation and data treatment (e.g. chemometrics) to shed new light on the ancient fossil record? \nPlanetary exploration: How can we effectively utilise space mission observations\, including rover and orbiter datasets\, to reconstruct past environments and habitability throughout the Solar System? \n  \n\n\n\nBook

SUMMARY:Geo-natter
DESCRIPTION:These informal meetings are the perfect opportunity to meet like-minded rock enthusiasts and chat about all things geological and palaeontological! \nA chance to look at rocks and fossils\, get your own specimens identified\, ask questions about geology and find out what’s happening locally. Tea and coffee provided. \n
