[PCG23-P05] The Venera-D Mission Concept for Exploring Venus
Keywords:Venus , Mission, Orbiter, Lander, Aerial Platform, Surface Station
Currently, the JSDT is assessing a mission architecture concept for the comprehensive investigation of Venus that would consist of an orbiter (>3 yr. of operation) and a lander (2 hrs. on the surface). The scientific goals of the concept are tied closely to the key objectives established by VEXAG and the NASA Planetary Decadal Survey, and include: investigation of the thermal structure and chemical composition of the atmosphere and clouds, abundances and isotopic ratios of the light and noble gases; study of the thermal balance, dynamics, and super-rotation of the atmosphere; determination of the surface mineralogy and elemental composition including key radioactive isotopes; study of potential current volcanic and electrical activity; and the study of the plasma environment, magnetosphere, and atmospheric escape. The JSDT is also evaluating technology needs and the potential for innovative flight element augmentations including, free flying aerial platforms, sub-satellites, and small long-lived surface stations. The study is continuing and will refine the mission architecture and potential instrument suite for the different flight elements.
