Morphological, structural, and spectral characteristics of amorphous iron sulfates [0.03%]
无定形铁硫酸的形态、结构和光谱特征

E C Sklute et al.
Current or past brine hydrologic activity on Mars may provide suitable conditions for the formation of amorphous ferric sulfates. Once formed, these phases would likely be stable under current Martian conditions, particularly at low- to mid...
Vortices in Saturn's Northern Hemisphere (2008-2015) Observed by Cassini ISS [0.03%]
卡西尼号 ISS 拍摄的 2008 年至 2015 年间土星北半球的大气旋涡结构

Harold Justin Trammell et al.
We use observations from the Imaging Science Subsystem on Cassini to create maps of Saturn's Northern Hemisphere (NH) from 2008 to 2015, a time period including a seasonal transition (i.e., Spring Equinox in 2009) and the 2010 giant storm. ...
Wind-Driven Erosion and Exposure Potential at Mars 2020 Rover Candidate-Landing Sites [0.03%]
火星2020候选着陆点的风蚀与出露潜力
Matthew Chojnacki,Maria Banks,Anna Urso
Matthew Chojnacki
Aeolian processes have likely been the predominant geomorphic agent for most of Mars' history and have the potential to produce relatively young exposure ages for geologic units. Thus, identifying local evidence for aeolian erosion is highl...

Anna Urso
Isolated landscapes largely shaped by aeolian processes can occur on Earth, while the majority of Mars' recent history has been dominated by wind-driven activity. Resultantly, Martian landscapes often exhibit large-scale aeolian features, i...
The Geologic Exploration of the Bagnold Dune Field at Gale Crater by the Curiosity Rover [0.03%]
好奇号巡视器在盖尔陨石坑拜格尔 dunefield的地质探测

Matthew Chojnacki
The Mars Science Laboratory rover Curiosity engaged in a monthlong campaign investigating the Bagnold dune field in Gale crater. What represents the first in situ investigation of a dune field on another planet has resulted in a number of d...
Investigating Mercury's South Polar Deposits: Arecibo Radar Observations and High-resolution Determination of Illumination Conditions [0.03%]
水星南极沉积物的研究：阿雷西博雷达观测和照明条件的高分辨率确定

Nancy L Chabot
There is strong evidence that Mercury's polar deposits are water ice hosted in permanently shadowed regions. In this study, we present new Arecibo radar observations of Mercury's south pole, which reveal numerous radar-bright deposits and s...
Sedimentary processes of the Bagnold Dunes: Implications for the eolian rock record of Mars [0.03%]
巴古特沙丘的沉积过程及其对火星风成岩记录的意义
R C Ewing,M G A Lapotre,K W Lewis et al.
R C Ewing et al.
The Mars Science Laboratory rover Curiosity visited two active wind-blown sand dunes within Gale crater, Mars, which provided the first ground-based opportunity to compare Martian and terrestrial eolian dune sedimentary processes and study ...
Chemistry, mineralogy, and grain properties at Namib and High dunes, Bagnold dune field, Gale crater, Mars: A synthesis of Curiosity rover observations [0.03%]
火星盖尔陨石坑拜诺利沙丘场纳米布和高地沙丘的化学、矿物学及颗粒特性：基于好奇号火星车观测结果的综合研究
B L Ehlmann,K S Edgett,B Sutter et al.
B L Ehlmann et al.
The Mars Science Laboratory Curiosity rover performed coordinated measurements to examine the textures and compositions of aeolian sands in the active Bagnold dune field. The Bagnold sands are rounded to subrounded, very fine to medium size...
Mineral paragenesis on Mars: The roles of reactive surface area and diffusion [0.03%]
火星上的矿物共生关系：反应性表面积和扩散的作用
Alberto G Fairén,Carolina Gil-Lozano,Esther R Uceda et al.
Alberto G Fairén et al.
Geochemical models of secondary mineral precipitation on Mars generally assume semiopen systems (open to the atmosphere but closed at the water-sediment interface) and equilibrium conditions. However, in natural multicomponent systems, the ...
Limited role for thermal erosion by turbulent lava in proximal Athabasca Valles, Mars [0.03%]
