Abstract The dynamics and evolution of Venus’ mantle are first-order relevance for the origin modification tectonic volcanic structures we observe on Venus today. Solid-state convection in induces stresses into lithosphere crust that drive deformation leading to signatures. Thermal coupling with atmosphere core leads a distinct structure substantial lateral heterogeneity, thermally compositionally. These processes ultimately shape regime provide framework interpret surface observations made Venus, such as gravity topography. Tectonic convective continuously changing through geological time, largely driven by long-term thermal compositional mantle. To date, no consensus has been reached geodynamic is presently in, mostly because observational data remains fragmentary. In contrast Earth, does not support existence continuous plate tectonics its surface. However, planet’s signature substantially deviates from those tectonically inactive bodies, Mars, Mercury, or Moon. This work reviews current state knowledge focussing dynamic system perspective. Available constrain deep interior evaluated their insufficiency pin down evolutionary path emphasised. Future missions will likely revive discussion these open issues boost our understanding filling gaps; some promising avenues discussed this chapter.

Abstract In this work we discuss various selected mission concepts addressing Venus evolution through time. More specifically, address investigations and payload instrument supporting scientific goals open questions presented in the companion articles of volume. Also included are their related (observations & modeling) discussion which measurements future data products needed to better constrain Venus’ atmosphere, climate, surface, interior habitability A new fleet missions has been selected, will continue be considered for selections. Missions under development include radar-equipped ESA-led EnVision M5 orbiter (European Space Agency 2021), NASA-JPL’s VERITAS (Smrekar et al. 2022a), NASA-GSFC’s DAVINCI entry probe/flyby (Garvin 2022a). The acquired with VERITAS, DAVINCI, from end decade fundamentally improve our understanding planet’s long term history, current activity evolutionary path. We further describe beyond framework missions, as well synergies between these concepts, ground-based space-based observatories facilities, laboratory measurements, algorithmic or modeling activities that pave way a program extends into 2040s (Wilson 2022).

Abstract Atla Regio is a large topographic rise, at the equator of Venus, considered to sit above young mantle upwelling. Hosting several giant shield volcanoes, including Maat Mons, it strong candidate for recent eruptive activity. Through detailed analysis material units and structures Ozza, Sapas northern Dali Chasma surrounding plains, we have unraveled tectono‐magmatic evolution Regio. Lithostratigraphic analysis, volcanic styles, lava flow relationships, rift–associated clusters, graben‐fissure systems pit cratering, in relation regional plains other older features, has enabled establishment model volcanism. Structural reveals that Ozza Mons transition outward into three major rifts, two new, unnamed volcanoes are identified. Our evidenced by stratigraphy cross‐cutting relationships with respect stratigraphic marker provided ejecta halo Uvaysi impact, using sound principles. A relative chronostratigraphic framework area around thus been constructed, our findings agreement prior research. new history proposed here, where volcanism was initially concentrated along Chasma, before plume took over finally, became most locus We propose pattern displaced centers here indicative minor crustal adjustments relatively long‐lived plume.
