“…However, the secondary process(es) that could have operated to evolve a pit crater into a large trough is not clear. Nonetheless, the prevalence of rampart craters in the region, as well as evidence given in previous work (e.g., Hajna et al, 2017;Rodriguez et al, 2016) for the presence of surface and groundwater within the troughs of Noctis Labyrinthus, support the possibility that interactions of pit craters with sub-surface volatiles (i.e., water ice) or groundwater could continue the modification and deepening of pit crater walls after initial formation by tectonic processes. Such a scenario is bolstered by global estimates for the depth of the current Martian cryosphereto be 0-5 km below the surface at equatorial latitudes (Clifford & Parker, 2001;Clifford et al, 2010).…”

“…At the bases of the large troughs in Noctis Labyrinthus is geomorphological evidence for landslides, periglacial processes, and karst (Hajna et al, 2017). For example, identified 232 landslides in the region, all within features mapped as troughs in this study (e.g., Figures 4 and 11).…”

“…The formation of the deep, large troughs at Noctis Labyrinthus has been postulated to have resulted from several processes, including lava tube collapse (Leone, 2014), magma body withdrawal (Andrews-Hanna, 2012a, 2012b, 2012c), tectonic processes leading to groundwater discharge and subsequent collapse (Rodriguez et al, 2016), and karstic dissolution of material (Hajna et al, 2017). In contrast, we infer from photogeological mapping and fault and pit crater analyses that the initial formation of Noctis Labyrinthus progressed from pit craters and normal fault systems that formed because of regional extensional tectonics.…”

“…Large troughs cross-cut both the normal faults and pit craters (Figure 1b). Additionally, hillslope modification within the troughs of Noctis Labyrinthus is evidenced by landslides and periglacial features (Hajna et al, 2017;Rodriguez et al, 2016) that together are indicative of mass-wasting processes that have helped shape the troughs.…”

“…Additional work has focused on the troughs in Noctis Labyrinthus and the physiographic landforms therein (Hajna et al, 2017;Rodriguez et al, 2016). Rodriguez et al (2016) argued for fault-controlled groundwater circulation through conduits with easternmost outlets in Valles Marineris, including some probably connected to outflow channel heads.…”

Introduction Noctis LabyrinthusNoctis Labyrinthus, Mars, is situated east of the Tharsis rise, at the western end of Valles Marineris (Figure 1a). Despite being located between the biggest volcanic complex and largest canyon system on the planet, the exact nature and formational history of Noctis Labyrinthus is not well understood. The region sits on a topographic high and could be considered a dissected dome or plateau (Andrews-Hanna, 2012a, 2012b, 2012c) (Figure 1b). The region abounds with normal faults (Bistacchi et al., 2004;Masson, 1977) and pit craters. Large troughs cross-cut both the normal faults and pit craters (Figure 1b). Additionally, hillslope modification within the troughs of Noctis Labyrinthus is evidenced by landslides and periglacial features (Hajna et al., 2017;Rodriguez et al., 2016) that together are indicative of mass-wasting processes that have helped shape the troughs.The broad structural characteristics of Noctis Labyrinthus have been recognized since the original mapping from Viking imagery by Masson (1977), who concluded that the region resembled the East African

Fundamental Science and Engineering Questions in Planetary Cave Exploration

et al. 2022

Nearly half a century ago, two papers postulated the likelihood of lunar lava tube caves using mathematical models. Today, armed with an array of orbiting and fly-by satellites and survey instrumentation, we have now acquired cave data across our solar system-including the identification of potential cave entrances on the Moon, Mars, and at least nine other planetary bodies. These discoveries gave rise to the study of planetary caves. To help advance this field, we leveraged the expertise of an interdisciplinary group to identify a strategy to explore caves beyond Earth. Focusing primarily on astrobiology, the cave environment, geology, robotics, instrumentation, and human exploration, our goal was to produce a framework to guide this subdiscipline through at least the next decade. To do this, we first assembled a list of 198 science and engineering questions. Then, through a series of social surveys, 114 scientists and engineers winnowed down the list to the top 53 highest priority questions. This exercise resulted in identifying emerging and crucial research areas that require robust development to ultimately support a robotic mission to a planetary caveprincipally the Moon and/or Mars. With the necessary financial investment and institutional support, the research and technological development required to achieve these necessary advancements over the next decade WYNNE ET AL.
