High-Resolution Observations of Planetary Geological and Geomorphic Investigation (Second Edition)

Dear Colleagues,

As some of the emerging topics in current scientific research, planetary geology and geomorphology exploration have reshaped our understanding of the space world. The continuous improvement in planetary remote sensing technology has greatly supported planetary geology and geomorphology investigation, as well as numerous scientific studies on the Moon, Mars and other planetary bodies in the solar system. In addition, it is regarded as one of the indispensable technologies for planetary exploration. Remote sensing data can be used to study planetary surface processes, identify sediments in planetary craters, detect liquid water on Mars, measure space weathering rates, reconstruct geological history, etc.

Only with high-resolution data can remote sensing be effectively used to observe these planetary landforms and topographic features. For Mars, there are many similar high-resolution data sets available; for example, the High-Resolution Imaging Sensor Experiment (HiRISE), the Color and Stereo Surface Imaging System (CaSSIS), the High-Resolution Stereo Camera (HRSC), and the Mars Orbiter Camera (MOC), etc., have provided repeated high-resolution images of Mars, and many discoveries of active processes have been made on the Martian surface. In addition, Spectrometers and Imagers for MPO BepiColombo Integrated Observatory SYStem of ESA’s BepiColombo Mercury mission also played an important role in data collection and in the terrain reconstruction of Mercury. Additionally, the Lunar Reconnaissance Orbiter (LRO) and Lunar Reconnaissance Orbiter Camera (LROC) for lunar exploration are necessary for the generation of a high-resolution Digital Elevation Model (DEM). However, there are still major challenges in planetary exploration, such as how to extract high-resolution images of smaller ranges or specific objects from a high-resolution image (HRI), precise landing site positioning, and accurate terrain reconstruction processing methods, etc.

This Special Issue aims to document expertise in the exploration of all aspects of planetary geology, geomorphology, and landscape evolution through high-resolution observation, as well as contributions to the study of terrestrial planets. Topics include, but are not limited to, exploring planetary geomorphology, planetary surface processes, shallow subsurface tectonics, and space weathering using high-resolution (HR) and very-high-resolution (VHR) satellites.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
