Water has supposedly marked the surface of Mars and produced characteristic landforms. To understand the history of water on Mars, we take a close look at key locations with the High-Resolution Imaging Science Experiment on board the Mars Reconnaissance Orbiter, reaching fine spatial scales of 25 to 32 centimeters per pixel. Boulders ranging up to ∼2 meters in diameter are ubiquitous in the middle to high latitudes, which include deposits previously interpreted as finegrained ocean sediments or… 

Investigating evidence of geologically recent liquid water on Mars

Geologically young gullies have been proposed to be evidence of recent liquid water on Mars. This dissertation details work I have done to address issues surrounding the Martian gullies and recent

Examination of gully sites on Mars with the shallow radar

[1] Martian gullies, found on steep slopes along broad mid-latitudinal bands, have morphologies resembling those of water-carved gullies on Earth and have been dated to <10 Ma. As such, one of the

Geology of Mars

A principal scientific objective for sending spacecraft to Mars has been to explore its geology as interpreted from data returned to Earth (see Chapter 2 for a review of the history of Mars

Formation of gullies on Mars: Link to recent climate history and insolation microenvironments implicate surface water flow origin

TLDR
Analysis of the insolation geometry of this pole-facing crater wall, and similar occurrences in other craters at these latitudes on Mars, shows that they are uniquely favored for accumulation of snow and ice, and a relatively more rapid exposure to warmer summer temperatures.

HiRISE observations of new impact craters exposing Martian ground ice

Twenty small new impact craters or clusters have been observed to excavate bright material inferred to be ice at mid‐latitudes and high latitudes on Mars. In the northern hemisphere, the craters are

ooting crater: Geology and geomorphology of the archetype large, fresh, impact rater on Mars

The 27.2 km diameter Tooting crater is the best preserved young impact crater of its size on Mars. It offers an unprecedented opportunity to study impact-related phenomena as well the geology of the

Evidence for recent climate change on Mars from the identification of youthful near-surface ground ice

TLDR
Observational evidence for a mid-latitude reservoir of near-surface water ice occupying the pore space of soils is reported and it is inferred that the reservoir was created during the last phase of high orbital obliquity less than 100,000 years ago, and is now being diminished.

Mars Global Surveyor Mars Orbiter Camera: Interplanetary cruise through primary mission

More than 3 years of high-resolution (1.5–20 m/pixel) photographic observations of the surface of Mars have dramatically changed our view of that planet. Among the most important observations and

Modeling water ice lifetimes at recent Martian gully locations

Mars Global Surveyor identified two instances of recent changes in gully morphology. Images suggest that two gullies had recent discharges of some liquid, leaving a residue behind. The residue might

Formation of recent martian gullies through melting of extensive water-rich snow deposits

TLDR
It is shown that gullies can form by the melting of water-rich snow that has been transported from the poles to mid-latitudes during periods of high obliquity within the past 105 to 106 years.

Present-Day Impact Cratering Rate and Contemporary Gully Activity on Mars

TLDR
The Mars Global Surveyor Mars Orbiter Camera has acquired data that establish the present-day impact cratering rate and document new deposits formed by downslope movement of material in mid-latitude gullies on Mars, suggesting that liquid water flowed on the surface of Mars during the past decade.

Environmental Effects of Large Impacts on Mars

TLDR
The martian valley networks formed near the end of the period of heavy bombardment of the inner solar system, about 3.5 billion years ago, and warmed the surface, keeping it above the freezing point of water for periods ranging from decades to millennia, depending on impactor size.

Fracture-Controlled Paleo-Fluid Flow in Candor Chasma, Mars

TLDR
These findings demonstrate that fluid flow along fractures was a mechanism by which subsurface fluids migrated through these layered deposits and are thus promising sites for investigating the geologic history of water on Mars.

Martian permafrost features

The outgassing history of Mars and the prevailing temperature conditions suggest that ground ice may occur to depths of kilometers over large areas of the planet. The presence of permafrost is also
