Abstract An exciting and novel science mission concept called Seismic and Atmospheric Exploration of Venus (SAEVe) has been developed which uses high-temperature electronics to enable a three-order magnitude increase in expected surface life (120 Earth days) over what has been achieved to date. This enables study of long-term, variable phenomena such as the seismicity of Venus and near surface weather, near surface energy balance, and atmospheric chemical composition. SAEVe also serves as a critical pathfinder for more sophisticated landers in the future. For example, first order seismic measurements by SAEVe will allow future missions to deliver better seismometers and systems to support the yet unknown frequency and magnitude of Venus events. SAEVe is focused on science that can be realized with low data volume instruments and will most benefit from temporal operations. The entire mission architecture and operations maximize science while minimizing energy usage and physical size and mass. The entire SAEVe system including its protective entry system is estimated to be around 45 ​kg and approximately 0.6 ​m diameter. These features allow SAEVe to be relatively cost effective and be easily integrated onto a Venus orbiter mission. The technologies needed to implement SAEVe are currently in development by several funded activities. Component and system level work is ongoing under NASA’s Long Lived Insitu Solar System Explorer (LLISSE) project and the HOTTech program. . LLISSE, is a NASA project to develop a small Venus lander that will operate on the surface of Venus for 60 days and measure variations in meteorology, radiance, and atmospheric chemistry. LLISSE is developing a full-function engineering model of a Venus lander that contains essentially all the core capabilities of SAEVe thus greatly reducing the technology risk to SAEVe. The SAEVe long duration Venus lander promises exciting new science and is an ideal complimentary element to many future Venus orbiter missions being proposed or planned today.

用于地震和大气科学的长期金星着陆器

摘要 已开发出一种名为金星地震和大气探测 (SAEVe) 的激动人心且新颖的科学任务概念，该概念使用高温电子设备使预期的地表寿命（120 个地球日）比已取得的成果增加了三个数量级。日期。这使得能够研究长期的、可变的现象，例如金星的地震活动和近地表天气、近地表能量平衡和大气化学成分。SAEVe 还可以作为未来更复杂着陆器的关键探路者。例如，SAEVe 的一阶地震测量将使未来的任务能够提供更好的地震仪和系统，以支持未知的金星事件频率和震级。SAEVe 专注于可以通过低数据量仪器实现的科学，并且最能从时间操作中受益。整个任务架构和操作最大限度地提高了科学性，同时最大限度地减少了能源使用和物理尺寸和质量。整个 SAEVe 系统包括其保护进入系统估计约为 45 公斤，直径约为 0.6 米。这些功能使 SAEVe 具有相对成本效益，并且可以轻松集成到金星轨道飞行器任务中。实施 SAEVe 所需的技术目前正在由几项资助活动开发。在 NASA 的长寿命原位太阳系探索器 (LLISSE) 项目和 HOTTech 计划下，组件和系统级工作正在进行中。. 利斯，是 NASA 的一个项目，旨在开发一个小型金星着陆器，该着陆器将在金星表面运行 60 天，并测量气象、辐射和大气化学的变化。LLISSE 正在开发金星着陆器的全功能工程模型，该模型基本上包含 SAEVe 的所有核心功能，从而大大降低了 SAEVe 的技术风险。SAEVe 长持续时间金星着陆器承诺令人兴奋的新科学，是当今提议或计划的许多未来金星轨道飞行器任务的理想补充元素。
