The Europlanet 2024 Research Infrastructure provides access to well characterised field sites that represent the most realistic terrestrial geological-geomorphological analogues for volcanic, dry-and humid-cold, hot, highly saline and metalliferous and impact conditions for studies in support of current and forthcoming missions to Mars, the Moon and the icy moons of Jupiter. Europlanet 2024 RI offers free ‘transnational access’ to seven diverse PFA sites around the world that have been comprehensively characterised. This enables researchers to undertake multi-disciplinary research programmes in support of planetary missions allowing to: • quantify the complex (bio) geo-chemical feed-back processes that control planetary evolution: • develop (quantified) models to explain observations of planets in our Solar System from rovers: orbiting instruments, and ground-based observations and (potentially) interpret data from exoplanets. • study the processes that influence the strategy and adaption of life to extreme conditions: • test our ability to detect unambiguously records of past or present biological activity: • test new instrumentation and operational systems for future planetary space missions under fully operational conditions: Iceland offers a multitude of different environments, including glacial and sub-glacial environments, lava fields of different ages, volcanic areas and active hydrothermal systems. The Greenland Kangerlussuaq field site provides excellent access to a glacial ice sheet and regions with permafrost, glacial sediment deposits and also glacial run-off which meets the ocean. The Makgadikgadi pans of Botswana represent the largest inland evaporitic basin in the world. The pans provide different environments that vary from the playa lake with the ephemeral spring to a fossil dunes field. The unique nature of Rio Tinto, Spain, is caused by rock-water-biology interactions that produces a river with a pH of ~ 2.3 over a length of ~ 100 km. Unfortunately, due to political instability, the acidic hydrothermal and highly saline environments of the Danakil Depression in Ethiopia are currently inaccessible. However, two new field areas will be made available for Europlanet TA access in subsequent calls: i) the Qaidam Basin in the north of the Tibetan Plateau includes Mars-analog lacustrine environments and ii) the Puna, Patagonia and Tierra del Fuego regions in Argentina provide access to cold and wet-cold, extreme glacial and lacustrine environments. The presentation will briefly review the characteristics of the Planetary Field Analogues. More details are available at: https://www.europlanet-society.org/europlanet-2024-ri/ta1-pfa/
