Abstract

Mars is characterized by geological landforms familiar to terrestrial geologists. It has a tenuous atmosphere that evolved differently from that of Earth and Venus and a differentiated inner structure. Our knowledge of the structure and evolution of Mars has strongly improved thanks to a huge amount of data of various types (visible and infrared imagery, altimetry, radar, chemistry, etc) acquired by a dozen of missions over the last two decades. In situ data have provided ground truth for remote-sensing data and have opened a new era in the study of Mars geology. While large sections of Mars science have made progress and new topics have emerged, a major question in Mars exploration—the possibility of past or present life—is still unsolved. Without entering into the debate around the presence of life traces, our review develops various topics of Mars science to help the search of life on Mars, building on the most recent discoveries, going from the exosphere to the interior structure, from the magmatic evolution to the currently active processes, including the fate of volatiles and especially liquid water.

火星:一个小的类地行星

火星的地质地貌为陆地地质学家所熟悉。它有着与地球和金星不同的稀薄大气层和不同的内部结构。我们对火星结构和演化的认识大大提高了，这要归功于过去二十年来十几个任务获得的大量不同类型的数据(可见光和红外图像、测高、雷达、化学等)。实地数据为遥感数据提供了地面真实性，并开启了火星地质研究的新时代。虽然火星科学的大部分领域已经取得了进展，新的课题也出现了，但火星探索的一个主要问题——过去或现在存在生命的可能性——仍然没有得到解决。在不进入关于生命痕迹存在的争论的情况下，我们的评论发展了火星科学的各种主题，以帮助寻找火星上的生命，建立在最近的发现之上，从外逸层到内部结构，从岩浆演化到目前活跃的过程，包括挥发物的命运，特别是液态水。

期刊介绍： The Astronomy and Astrophysics Review is a journal that covers all areas of astronomy and astrophysics. It includes subjects related to other fields such as laboratory or particle physics, cosmic ray physics, studies in the solar system, astrobiology, instrumentation, and computational and statistical methods with specific astronomical applications. The frequency of review articles depends on the level of activity in different areas. The journal focuses on publishing review articles that are scientifically rigorous and easily comprehensible. These articles serve as a valuable resource for scientists, students, researchers, and lecturers who want to explore new or unfamiliar fields. The journal is abstracted and indexed in various databases including the Astrophysics Data System (ADS), BFI List, CNKI, CNPIEC, Current Contents/Physical, Chemical and Earth Sciences, Dimensions, EBSCO Academic Search, EI Compendex, Japanese Science and Technology, and more.
