Venus has always attracted attention of the scientists. This planet is the Earth antipode with crashing pressure, hellishly hot surface, poisonous atmosphere, and stormy circulation. The key and still open question is why and when the evolutionary pathways of Earth and Venus so drastically diverged. Despite more than 20 space missions and associated intensive research, the planet still keeps many fundamental mysteries. The radar mapping Magellan, Pioneer-Venus and Venera-15 missions unveiled unusual geology of very young and volcanically active surface. The orbiting spacecraft, especially Pioneer-Venus (NASA), Venus Express (ESA) and Akatsuki (JAXA) performed comprehensive study of the Venus atmosphere, its temperature structure, composition, clouds, and dynamics. Significant efforts were put into investigation of the plasma environment, its interaction with the solar wind and escape processes. The space missions established basic understanding of the conditions and processes at Venus, but many of them still remain unexplored due to limited payload capabilities. This talk will overview the current knowledge about Venus, outline the progress expected from EnVision, VERITAS and DAVINCI missions, identify remaining knowledge gaps and outline possible future mission concepts. 

Dmitrij V. TITOV教授于1981年毕业于莫斯科物理技术学院，1985年获博士学位后任职于莫斯科空间研究所（IKI），担任高级科学家；随后于1998年至2010年在德国马克斯·普朗克太阳系研究所担任高级研究员。2011年至2022年期间，Dmitrij V.

Titov教授在欧空局行星探测任务的科学管理方面贡献卓著。他曾担任“金星快车”任务科学协调员、“火星快车”任务项目科学家，以及“木星冰卫星探测器”（JUICE）和“恩维星”（EnVision）任务研究科学家。此外，他还是国际空间研究委员会（COSPAR）泽尔多维奇奖和欧洲地球科学联盟（EGU）大卫·贝茨奖章的获得者。

Prof. Dr. Dmitrij V. TITOV graduated from Moscow Institute of Physics and Technology in 1981. After receiving PhD degree in 1985 he worked as senior scientist at the Space Research Institute (IKI) (Moscow), and then, in 1998-2010, as a senior researcher at the Max Planck Institute for Solar System Research (Germany). In 2011-2022 D. Titov was the staff scientist at ESTEC/ESA (European Space Research and Technology Centre of the European Space Agency). Since 2022 D. Titov is the adjunct lecturer at Leiden University (The Netherlands). In 2024 he became a professor at Sun Yat-sen University (Zhuhai Campus). The main scientific interests and achievements of D. Titov are in the field of remote sensing of planets, structure, cloud morphology, radiative energy balance and dynamics of the Venus atmosphere, and water cycle on Mars. Dr. Titov was the co-investigator in many space experiments on Soviet, ESA and NASA missions. D. Titov significantly contributed to the science management of ESA planetary missions. He was the science coordinator of Venus Express, the project scientist for Mars Express, the study scientist for Jupiter Icy Moons Explorer (JUICE) and EnVision. D. Titov is a recipient of Zeldowich Award of COSPAR and David Bates medal of EGU.
