Astrogeology

These astrogeology dissertation examples are student-contributed and focus on the geology of planetary bodies — how surfaces are formed, altered, and interpreted using remote sensing and mission data. Students in astrogeology often build dissertations around one target (Mars, the Moon, asteroids, icy moons) and one process (impact cratering, volcanism, tectonics, erosion, regolith development, or past water activity), then test interpretations against mapped evidence.

Common themes include planetary surface mapping using orbital imagery, interpreting landforms and stratigraphy, and using crater counts to estimate relative ages. Many projects examine the signatures of past environments, such as channel networks, deltas, sedimentary layering, or mineral indicators of alteration, and what they imply about habitability. Method-heavy dissertations frequently use GIS workflows, spectral datasets (e.g., mineral mapping), photogeology, and comparative planetology (what Earth analogues can and cannot tell us). Students also explore mission constraints and uncertainty: resolution limits, lighting effects, incomplete coverage, and how competing hypotheses can fit the same surface features. Some topics extend to meteorites and impact processes, linking planetary materials to surface evolution.

Use these astrogeology dissertation examples to develop keywords such as planetary geomorphology, crater chronology, remote sensing, GIS mapping, regolith, volcanism, sedimentary processes, and comparative planetology.
