GAUSS -- A Sample Return Mission to Ceres
AI总结：
GAUSS旨在通过返回谷神星样本研究其起源、演化及潜在宜居性，探索其地质结构、水历史及生命起源可能性。
摘要：
GAUSS项目的目标是返回谷神星样本，以研究其起源、演化及潜在宜居性，探索其地质结构、水历史及生命起源的可能性。谷神星是目前最易接近的海洋世界候选者，也是太阳系内最大的水储备库。其近期表现出的活跃冰火山活动和水热活动导致了目前除地球地壳外其他行星未发现的矿物。可能存在的近期地下海洋及复杂的地球化学特性表明了过去可能的宜居性，甚至可能持续的宜居性。GAUSS旨在回答关于谷神星起源和演化的广泛问题及其潜在宜居性，将首次返回该可能的海洋世界样本。项目将回答以下顶级科学问题：1）谷神星的起源及太阳系内水和其他挥发性物质的起源和转移是什么？2）谷神星的物理性质和内部结构是什么？它们告诉我们什么关于冰质矮行星的演化和水蚀变历史？3）谷神星的天体生物学意义是什么？它过去是否宜居，现在是否仍然宜居？4）谷神星与我们目前收集的原始陨石之间的矿物学联系是什么？GAUSS将首先进行高分辨率全球遥感调查，表征谷神星的地球物理和地球化学性质。候选采样地点将被确定，然后进行观察活动以深入评估候选地点。一旦选定采样地点，将部署着陆器在表面采集样本并将其以低温条件返回地球，以尽可能保持挥发性物质和有机物的组成以及原始物理状态。
英文摘要：
The goal of Project GAUSS is to return samples from the dwarf planet Ceres. Ceres is the most accessible ocean world candidate and the largest reservoir of water in the inner solar system. It shows active cryovolcanism and hydrothermal activities in recent history that resulted in minerals not found in any other planets to date except for Earth's upper crust. The possible occurrence of recent subsurface ocean on Ceres and the complex geochemistry suggest possible past habitability and even the potential for ongoing habitability. Aiming to answer a broad spectrum of questions about the origin and evolution of Ceres and its potential habitability, GAUSS will return samples from this possible ocean world for the first time. The project will address the following top-level scientific questions: 1) What is the origin of Ceres and the origin and transfer of water and other volatiles in the inner solar system? 2) What are the physical properties and internal structure of Ceres? What do they tell us about the evolutionary and aqueous alteration history of icy dwarf planets? 3) What are the astrobiological implications of Ceres? Was it habitable in the past and is it still today? 4) What are the mineralogical connections between Ceres and our current collections of primitive meteorites? GAUSS will first perform a high-resolution global remote sensing investigation, characterizing the geophysical and geochemical properties of Ceres. Candidate sampling sites will then be identified, and observation campaigns will be run for an in-depth assessment of the candidate sites. Once the sampling site is selected, a lander will be deployed on the surface to collect samples and return them to Earth in cryogenic conditions that preserves the volatile and organic composition as well as the original physical status as much as possible.
