Dynamic Mars. Recent and Current Landscape Evolution of the Red Planet

Authors

Richard J. Soare Professor, Department of Geography, Dawson College, Canada. Richard Soare is a physical geographer specializing in periglacial (cold-climate, non-glacial landscapes). Through the last twenty years he has spent considerable time off-planet, intellectually, i.e. identifying landscapes on Mars present or past possibly molded by the freeze-thaw cycling of water. His work spans the red planet geographically, ranging from the plains of Utopia Planitia in the northern hemisphere and the Moreux impact-crater at the Mars dichotomy through to the Argyre impact-crater in the southern hemisphere. Recently, he co-edited Dynamic Mars: Recent and Current Landscape Evolution on the red planet and a special issue of Icarus: Current and Recent Landscape Evolution on Mars. Susan J. Conway CNRS Researcher, CNRS UMR 6112 Laboratoire de Planetologie et Geodynamique, Universite de Nantes, France. Susan Conway is a CNRS research scientist in Nantes, France, having graduated with a PhD in planetary science from the Open University (United Kingdom) in 2010. She is chair of the International Association for Geomorphologists (IAG) Planetary Geomorphology Working Group, and has run the Planetary Geomorphology session at the European Geoscience Union since 2011. She is lead editor for a collection of papers on Martian gullies and their Earth analogues, based on the workshop she organized at the Geological Society of London in June 2016 and is co-editor on a collection of papers entitled "Frontiers in Geomorphometry". She is a team member on the High Resolution Imaging Science Experiment (HiRISE) instrument on NASA's Mars Reconnaissance Orbiter and Guest Investigator on the ESA Trace Gas Orbiter mission to Mars, specifically focused on the CaSSIS camera and NOMAD/ACS spectrometer instruments. She is on the author list of 35 peer-reviewed papers concerning the geomorphology of Earth, Mars, Mercury, the Moon and the asteroid Vesta. Her work is concentrated around glacial, periglacial and fluvial landforms on Mars, encompassing field, remote sensing and laboratory simulation data, with a specialty in analysis of 3D terrain data. Stephen M. Clifford Senior Scientist, Planetary Science Institute, Tucson, Arizona, USA. Stephen Clifford is a Senior Scientist at the Planetary Science Institute in Tucson, Arizona. He received his PhD in Astronomy from the University of Massachusetts in 1984. His research focuses on the nature, evolution and geophysical investigation of planetary volatiles, with a special emphasis on water on Mars. He is the author/co-author of 70 peer-reviewed publications whose topical focus has varied from investigations of H2O transport in cold planetary regoliths; large-scale groundwater transport; low-temperature hydrothermal convection in a sub-permafrost vadose zone; the formation and stability of gas hydrates; glacial flow and polar evolution; thermal modelling of planetary surfaces; the thermal, seismic and hydrologic effects of impact catering; and radar investigations of subsurface geology and the distribution and state of H2O. He was the principal convener of the 1st-4th International Conferences on Early Mars, 1st-5th International Conferences on Mars Polar Science and Exploration, and the Conference on the Geophysical Detection of Subsurface Water on Mars. Steve is the Deputy Science Team Leader for the WISDOM Ground Penetrating Radar which is part of the payload of ESA's 2020 ExoMars Rover. He is also a U.S. Participating Scientist on the MARSIS orbital radar sounder on ESA's Mars Express mission. Prior to joining the science staff at PSI in February 2018, Steve was a Senior Staff Scientist at the Lunar and Planetary Institute in Houston, Texas, where he conducted his Mars research for 34 years.
