Ocean Worlds: A Roadmap for Science and Exploration

Many of the ROW results are summarized by Hendrix and Hurford et al. (2019). In this white paper we summarize the mission priorities for Ocean Worlds in the next ~decade. Because this is a community document, numerous authors have contributed including those listed below. Accompanying white papers review science goals and technologies.

The case for a multi-channel polarization sensitive LIDAR for investigation of insolation-driven ices and atmospheres Planetary Science Decadal Survey White Paper

And met many of our Mars Climate Goals."-Anon. 2020 Key point of this white paper: All LIDAR instruments are not the same, and advancement of LIDAR technology requires an ongoing interest and demand from the community to foster further development of the required components. The purpose of this paper is to make the community aware of the need for further technical development, and the potential payoff of investing experimental time, money and thought into the next generation of LIDARs. Technologies for development: We advocate for future development of LIDAR technologies to measure the polarization state of the reflected light at selected multiple wavelengths, chosen according to the species of interest (e.g., H 2 O and CO 2 in the Martian setting). Key scientific questions: In the coming decade, dollars spent on these LIDAR technologies will go towards addressing key climate questions on Mars and other rocky bodies, particularly those with seasonally changing (i.e. insolation driven) plumes of multiple icy volatiles such as Mars, Enceladus, Triton, or Pluto, and insolation-driven dust lifting, such as cometary bodies and the Moon. We will show from examining past Martian and terrestrial lidars that orbital and landed LIDARs can be effective for producing new insights into insolation-driven processes in current planetary climate on several bodies, beyond that available to our current fleet of largely passive instruments on planetary missions.

Using satellite imagery to identify and analyze tumuli on Earth and Mars

Earth and Planetary Science Letters, 2018

Tumuli are small, dome-like features that form when magmatic pressures build within a subsurface ... more Tumuli are small, dome-like features that form when magmatic pressures build within a subsurface lava pathway, causing the overlying crust to bulge upwards. As the appearance of these features has been linked to lava flow structure (e.g., underlying lava flow tubes) and conditions, there is interest in identifying such features in satellite images so they can be used to expand our understanding of lava flows within regions difficult to access (such as on other planets). Here, we define a methodology for identifying (and measuring) tumuli within satellite imagery, and validate it by comparing our results with fieldwork results of terrestrial tumuli reported in the literature and with independent measurements we made within Amboy Field, CA. In addition, we present aggregated results from the application of our methodology to satellite images of six terrestrial fields and seven martian fields (with >2100 tumuli identified, per planet). Comparisons of tumuli morphometrics on Earth and Mars yield similarities in size and overall shape, which were surprising given the many differences in the environmental and planetary conditions within which these features have formed. Given our measurements, we identify constraints for tumulus formation models and drivers that would yield similar shapes and sizes on two different planets. Furthermore, we test a published hypothesis regarding the number of tumuli that form per a square kilometer, and find it unlikely that a diagnostic "tumuli density" value exists.

Preparation for the Planetary Decadal Survey: The 2018 MEPAG Goals Document and Plans for 2019 Updates

This "Goals Document" is a living document that is revised regularly (~every few years) in light of new Mars science results, and it serves as a reference for science priority for Mars-related flight and research projects. It is organized into a hierarchy of goals, objectives, and investigations (Figure 1, Table 1). The four Goals are not prioritized and are organized around major areas of scientific knowledge: "Life", "Climate", "Geology", and "Preparation for Human Exploration". Don Banfield (Cornell University) is the current MEPAG Goals Committee Chair, and he oversees 2-3 representatives per Goal (Table 1) [2].

The formation of gullies on Mars today

Geological Society, London, Special Publications, 2017

A decade of high-resolution monitoring has revealed extensive activity in fresh Martian gullies. ... more A decade of high-resolution monitoring has revealed extensive activity in fresh Martian gullies. Flows within the gullies are diverse: they can be relatively light, neutral or dark, colourful or bland, and range from superficial deposits to 10 m-scale topographic changes. We observed erosion and transport of material within gullies, new terraces, freshly eroded channel segments, migrating sinuous curves, channel abandonment, and lobate deposits. We also observed early stages of gully initiation, demonstrating that these processes are not merely modifying pre-existing landforms. The timing of activity closely correlates with the presence of seasonal CO2 frost, so the current changes must be part of ongoing gully formation that is driven largely by its presence. We suggest that the cumulative effect of many flows erodes alcoves and channels, and builds lobate aprons, with no involvement of liquid water. Instead, flows may be fluidized by sublimation of entrained CO2 ice or other mecha...

Current knowledge was drawn from many studies about cratering dynamics in the strength regime and in porous material, ejecta velocity distributions, and 25143 Itokawa&amp;#x27;s probable interior structure. Based on all of this, it has been shown that this asteroid should not have a deep, global regolith layer like that found on 433 Eros. Instead, small and thin (millimeters to centimeters) patches of regolith ...
