在最近发表的一篇论文中，NASA的科学家和工程师提供了有关该局稀有气体、化学和成像深大气层金星调查任务（Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging , DAVINCI）的新细节，该任务将于2031年中期穿过金星的多层大气到达金星表面。达芬奇是第一个利用航天器飞掠和降落探测器研究金星的任务。 飞行分析化学实验室达芬奇将首次测量金星大规模大气气候系统的关键方面，其中许多自20世纪80年代初以来一直是金星的测量目标。它还将提供金星山地高地的首次降落图像，同时以轨道不可能的尺度绘制其岩石成分和地表地形。该任务支持对少量存在的未发现气体和最深处大气的测量，包括氢同位素的关键比例——水的组成成分，有助于揭示水的历史，无...
