Venus, often called as the twin sister planet of the earth, fosters the environment extremely different from that of the earth. Our knowledge about Venus has advanced by ESA's Venus Express and JAXA's Akatsuki missions mostly about its atmosphere (the former is primarily for the chemistry and the latter for the dynamics). Two of the upcoming 3 Venus missions, NASA's VERITAS and ESA's EnVision, are more focused on the geology, interior and evolution of the solid planet, Venus with synthetic aperture radar technique. Another NASA mission DAVINCI sense both the atmosphere and the surface by a descent probe. There may be more to come, such as Chinese VOICE, Indian Shukurayaan-1, Russian Venera-D, and even from a private company (inclined to the astrobiology).

This momentum is supported by the analysis studies with the previous and the current Venus missions, numerical simulations (recently with data assimilation), ground-based observations, laboratory experiments, etc. This session will therefore cover all aspects of science related to Venus, from its interior to the surrounding plasma environment, either by observationally or by theoretically. Implications to the exoplanets are also important objectives of studies of Venus. Contributions by all levels, from early-career researchers to experts, are all welcome.
