In June 2021, NASA and ESA selected a fleet of three international missions to Venus. Moreover, the ISRO orbiter mission Shukrayyan-1 and VOICE (Chinese Academy of Sciences) are currently proposed for launch in the mid 2020s. With the ‘Decade of Venus’ upon us, many fundamental questions remain regarding Venus. Did Venus ever have an ocean? How and when did intense greenhouse conditions develop? How does its internal structure compare to Earth's? How can we better understand Venus’ geologic history as preserved on its surface as well as the present-day state of activity and couplings between the surface and atmosphere? Although Venus is one of the most uninhabitable planets in the Solar System, understanding our nearest planetary neighbor may unveil important lessons on atmospheric and surface processes, interior dynamics and habitability. It may further help us draw important conclusions on the history of our own planet. Beyond the solar system, Venus’ analogues are likely a common type of exoplanets, and we likely have already discovered many of Venus’ sisters orbiting other stars. This session welcomes contributions that address the past, present, and future of Venus science and exploration, and what Venus can teach us about (ancient) Earth as well as exo-Venus analogues. Moreover, Venus mission concepts, new Venus observations, Earth-Venus comparisons, exoplanet observations, new results from previous observations, and the latest lab and modelling approaches are all welcome to our discussion of solving Venus’ mysteries.
