Abstract

The Close-Up Imager (CLUPI) onboard the ESA ExoMars Rover is a powerful high-resolution color camera specifically designed for close-up observations. Its accommodation on the movable drill allows multiple positioning. The science objectives of the instrument are geological characterization of rocks in terms of texture, structure, and color and the search for potential morphological biosignatures. We present the CLUPI science objectives, performance, and technical description, followed by a description of the instrument's planned operations strategy during the mission on Mars. CLUPI will contribute to the rover mission by surveying the geological environment, acquiring close-up images of outcrops, observing the drilling area, inspecting the top portion of the drill borehole (and deposited fines), monitoring drilling operations, and imaging samples collected by the drill. A status of the current development and planned science validation activities is also given. Key Words: Mars-Biosignatures-Planetary Instrumentation. Astrobiology 17, 595-611.

摘要

欧洲航天局“火星外生物学探测器”搭载的特写成像仪（CLUPI）是一款功能强大的高分辨率彩色相机，专为特写观测而设计。它安装在可移动钻头上，可实现多种定位。该仪器的科学目标是对岩石的纹理、结构和颜色进行地质特征描述，并寻找潜在的形态学生物特征。我们介绍了CLUPI的科学目标、性能和技术描述，随后描述了该仪器在火星任务期间计划采用的操作策略。CLUPI将通过勘测地质环境、获取露头特写图像、观测钻探区域、检查钻孔顶部（以及沉积的细粒物质）、监测钻探操作以及对钻头采集的样本进行成像，为探测器任务做出贡献。文中还给出了当前的研制状态以及计划开展的科学验证活动。关键词：火星 - 生物特征 - 行星仪器。天体生物学17, 595 - 611。
