Thermal Inertia Controls on Titan’s Surface Temperature and Planetary Boundary Layer Structure

The Planetary Science Journal
Understanding Titan’s planetary boundary layer (PBL)—the lowest region of the atmosphere influenced by surface conditions—remains challenging due to Titan’s thick atmosphere and limited observations.

A Geostratigraphic Map of the Rachmaninoff Basin Area: Integrating Morphostratigraphic and Spectral Units on Mercury

Earth and Space Science
Geological maps of Earth typically incorporate field observations of rock lithology, structure, composition, and more. In contrast, conventional planetary geological maps are often made using primarily qualitative morphostratigraphic remote sensing ...

Automated Global Feature Analyzer - A Driver for Tier-Scalable Reconnaissance [PDF]

, 2008
For the purposes of space flight, reconnaissance field geologists have trained to become astronauts. However, the initial forays to Mars and other planetary bodies have been done by purely robotic craft.

A Comprehensive Spectroscopic Reference of the Solar System and Its Application to Exoplanet Direct Imaging

The Planetary Science Journal
We present a calibrated database of reflectance spectra for the solar system planets (i.e., Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and for Titan, spanning from the ultraviolet to the near infrared.

Improved automatic impact crater detection on Mars based on morphological image processing and template matching

Geomatics, Natural Hazards & Risk, 2017
Impact craters help scientists to understand the geological history of planetary bodies. The aim of this paper is to improve the existing methodology for impact craters detection in images of planetary surfaces using a new approach based on morphological

Application of numerical methods to planetary radiowave scattering [PDF]

Existing numerical techniques for the solution of scattering problems were investigated to determine those which might be applicable to planetary surface studies, with the goal of improving the interpretation of radar data from Venus, Mars, the Moon, and

Subsurface Thermophysical Properties of Europa’s Leading and Trailing Hemispheres as Revealed by ALMA

The Planetary Science Journal
We present best-fit values of porosity—and the corresponding effective thermal inertiae—determined from three different depths in Europa’s near-subsurface (∼1–20 cm).
