Groundwater flow induced collapse and flooding in Noctis Labyrinthus, Mars

Published in Planetary and Space Science

Catastrophic floods of enormous proportions are thought to have played a major role in the excavation of some of the Solar System s largest channels; the circum-Chryse outflow channels. The generation of the floods has been attributed to both the evacuation of regional highland aquifers and ancient paleo-lakes. Numerous investigators indicate that ...

Fluvial geomorphology on Earth-like planetary surfaces: A review

Published in Geomorphology

Morphological evidence for ancient channelized flows (fluvial and fluvial-like landforms) exists on the surfaces of all of the inner planets and on some of the satellites of the Solar System. In some cases, the relevant fluid flows are related to a planetary evolution that involves the global cycling of a volatile component (water for Earth and Mar...

Martian outflow channels: How did their source aquifers form, and why did they drain so rapidly?

Published in Scientific Reports

Catastrophic floods generated~ 3.2 Ga by rapid groundwater evacuation scoured the Solar System s most voluminous channels, the southern circum-Chryse outflow channels. Based on Viking Orbiter data analysis, it was hypothesized that these outflows emanated from a global Hesperian cryosphere-confined aquifer that was infused by south polar meltwater ...

Constraints, Approach and Present Status for Selecting the Mars Surveyor 2001 Landing Site

There are many similarities between the Mars Surveyor 01 (MS 01) landing site selection process and that of Mars Pathfinder. The selection process includes two parallel activities in which engineers define and refine the capabilities of the spacecraft through design, testing and modeling and scientists define a set of landing site constraints based...
