Last updated:
9 November 2017
This issue includes papers from the 5th International Planetary Dunes Workshop that was held  in May 2017 in St. George, Utah. All  the papers focusing on eolian and fluvial bedforms on different bodies of our Solar System (including Earth) are welcomed. The papers of the special issue can focus on all aspects of the mechanism of bedform formation and development (geology, geomorphology, sedimentology, physics of transport and modeling). Papers on yardangs morphology and development are also welcomed. Attendance at the 5th IPDW is not required to submit a paper to the special issue.

Mars Aeronomy

The Mars upper atmosphere, ionosphere, magnetosphere, and solar-wind interactions are becoming increasingly important for understanding loss of atmosphere to space and the evolution of the Martian climate.  Recent observations have been made from Mars Express over the last decade, from MAVEN for the most-recent Mars year, and from Mars Odyssey, the Mars Reconnaissance Orbiter, and the Mars Orbiter Mission; landed spacecraft and earlier orbiters also provided valuable information. The International conference on Mars Aeronomy held in May 2017 in Boulder, Co, USA brought together all aspects of Mars aeronomy, including pertinent observations, analyses, theoretical models and results. The proposed special issue will collect the papers presented at the conference as well as will be open to all relevant manuscripts about the Mars upper atmosphere and space environment, even if the authors did not attend the conference. This collection is a joint special section between JGR-Space Physics and JGR-Planets, so the authors can submit manuscripts to either journal.

Investigations of the Bagnold Dune Field, Gale crater

The Bagnold Dune Field, Gale crater, is a large and active Martian sand deposit. This special issue welcomes publications studying the dunes, utilizing orbital data and/or the full suite of MSL instruments from Curiosity's winter 2015/2016 in situ investigation. Related papers on dunes and sands on Mars that contextualize the Bagnold dune field are also welcome.

This special issue is dedicated to Nathan Bridges, who co-organized the issue and passed away before it was completed.

Manuscripts should be submitted through the GEMS Web site for JGR Planets.

Planetary Mapping: Methods, Tools for Scientific Analysis and Exploration

Imaging, geologic and geospatial mapping of planetary surfaces is key to exploration. A growing wealth of data has triggered the development of new tools, capabilities and techniques for storing, serving, analyzing and interpreting planetary mission data. The process of planetary geologic and thematic mapping also evolves both in standards and practice with the availability of more diverse, more complex, complementary datasets. This special section aims at summarizing the state of the art and perspective of planetary mapping in broad sense (imaging, geospatial, geologic) and its underlying techniques for future robotic and human exploration of solid bodies in the Solar System. Encouraged topics of the special section include: planetary cartography, analysis and visualization tools, scientific case studies for geologic/geospatial mapping matching traditional and innovative approaches. This is a special joint section and will welcome software and algorithm development (Earth and Space Science) as well as scientific data analysis papers (JGR-Planets). Manuscripts should be submitted appropriately through the GEMS Web site for either JGR-Planets orEarth and Space Science.

Editors’ Highlights from Cassini Mission

After two decades of incredible exploration, the Cassini Mission to Saturn finished on September 15, 2017. The Cassini spacecraft has beamed back images and vast amounts of data, first from its flybys of Earth, Venus and Jupiter, then from 13 years spent circulating the ringed planet and its moons, as well as insights from landing the Huygens probe on the surface of Titan, the largest moon. According to NASA, 3948 science papers have been published as a result of the mission. A search for papers in AGU journals with Cassini mentioned in the abstract published since the mission started in 1997 generated more than 750 results across 6 different journals. We are very proud that AGU has played a significant role in publishing some of the important findings from the mission. We invited some of the editors to reflect on papers published in their journals and how they have contributed to our scientific understanding. Read their comments here; the papers they chose to highlight are included in this collection.
