This review paper has several aims: first, briefly to characterize planetary photogeology as a scientific discipline; second, to provide some sense of the rapid emergence of this field; third, to systematically review the literature over the past few years; and fourth, to identify the more significant problems for future analysis.To some degree, the ...

PSUP: A Planetary SUrface Portal
Planetary and Space Science, 2018The large size and complexity of planetary data acquired by spacecraft during the last two decades create a demand within the planetary community for access to the archives of raw and high level data and for the tools necessary to analyze these data.

Humanoids for lunar and planetary surface operations
5th IEEE-RAS International Conference on Humanoid Robots, 2005., 2006This paper presents a vision of humanoid robots as human's key partners in future space exploration, in particular for construction, maintenance/repair and operation of lunar/planetary habitats, bases and settlements. It integrates this vision with the recent plans for human and robotic exploration, aligning a set of milestones for operational ...

Bistatic Radar Occultations of Planetary Surfaces
IEEE Geoscience and Remote Sensing Letters, 2020Assessing the variability of surface roughness on planetary bodies is crucial for understanding the physical mechanisms that have governed their surface evolution. In addition, it provides constraints on surface texture uncertainties associated with landing, anchoring, surface trafficability, and sampling. Herein, we present how orbital bistatic radar (

Planetary Surface Temperatures
1991It is no news that the major source of heat energy in the solar system is the Sun. Its energy comes from nuclear reactions that take place at its core. The energy of a particular photon created in these reactions is absorbed and reradiated many times before reaching the surface, a process that takes on average about a million years.

Predicting the Strength of Planetary Surfaces
2022Our curiosity and spirit for exploration has fueled advancements towards visiting Earth's neighbors in the solar system. Environments outside of Earth are extreme, however, and it is far from guaranteed that landing and operating on the surface of these bodies is an easy task.

Mapping of planetary surfaces by radar
Proceedings of the IEEE, 1973A review is presented of the several methods which are available for the mapping of both reflectivity and topography of planetary surfaces by ground-based radar. Emphasis is placed on observational methods rather than interpretation of results. The various observational schemes are illustrated by recent observational results.

Planetary Surface Processes is the first advanced textbook to cover the full range of geologic processes that shape the surfaces of planetary-scale bodies. Using a modern, quantitative approach, this book reconsiders geologic processes outside the traditional terrestrial context.
