毅力号火星车矿物探测与样品采集进展(2021-2024年)
Progress in Mineral Exploration and Sample Collection by Perseverance Rover on Mars(2021-2024)
摘要
Abstract
NASA's Perseverance Mars rover successfully landed in Jezero crater(18.4°N,77.7°E)on 18 February 2021,and has been operating for nearly four years(2021-2024).To achieve these goals,Perse-verance is equipped with four spectrometric payloads:SuperCam,Mastcam-Z,Scanning Habitable Envi-ronments with Raman and Luminescence for Organics and Chemicals(SHERLOC)and Planetary Instru-ment for X-ray Lithochemistry(PIXL),allowing for detailed elemental and mineral analyses of surface materials.Comprehensive analyses have been conducted across several key geological units within Jezero crater,including the crater floor,delta front,upper fan,and margin unit.Each area's unique mineral compositions have been documented,revealing important information on Mars'geological and environ-mental evolution.The results indicate that Jezero crater region has undergone multiple aqueous alter-ation processes,leaving mineral evidence of historical water activity.These findings suggest that the re-gion,especially the west delta,was once exposed to prolonged aqueous environments,potentially provid-ing insights into Mars'paleoclimate,water salinity and possible habitability.Using its Sampling and Caching Subsystem(SCS),Perseverance has collected 21 rock core samples from various geological units,including igneous rocks from the crater floor and sedimentary rocks from the delta.These samples will undergo detailed analyses on Earth,expected to yield valuable insights into Mars'magmatic evolution,sedimentary history,water-rock interactions,geological development,and potential biosignatures.In summary,the comprehensive data collected by Perseverance has expanded our understanding of Mars,particularly Jezero crater,and provides a foundational reference for future Mars exploration and sample return missions,including China's Tianwen-3 mission.关键词
