This presentation was part of the session : Probe Missions to the Giant Planets, Titan and VenusSixth International Planetary Probe WorkshopIntroduction: To assess the feasibility and potential technology needs of a future planned Venus Flagship class mission, NASA is funding a mission study in this fiscal year (FY08). Such a mission was recommended in NASA's 2006 Solar System Exploration Roadmap [1] and in the NRC SSE Decadal Survey [2]. The final mission architecture is required to be in line with the primary science goals and objectives, as defined in the Venus Exploration Analysis Group (VEXAG) White Paper [3], and enabled by suitable extreme environments technologies [4]. In order to assist the Science and Technology Definition Team (STDT) for this year's study, an initial assessment was performed at JPL during the summer of 2007 [5], evaluating 17 potential mission architectures. Science requirements focused the architectures to near surface in situ missions only. Consequently, the studied architectures were bound by a New Frontiers (medium) class short lived surface mission concept at one end, working towards a future large Flagship class Venus Surface Sample Return (VSSR) mission at the other end, and through a number of architectures at various levels of complexities and corresponding cost levels. In this paper we outline the findings of last summer's study, including the recommended 3 key mission architecture groups - i.e., landers, mobile platforms, and geophysical networks - and link them to the final mission architecture from this year's study.
