The Mars Exploration Rover Opportunity has spent more than 2 years exploring Meridiani Planum, traveling ∼8 kilometers and detecting features that reveal ancient environmental conditions. These include well-developed festoon (trough) cross-lamination formed in flowing liquid water, strata with smaller and more abundant hematite-rich concretions than those seen previously, possible relict “hopper crystals” that might reflect the formation of halite, thick weathering rinds on rock surfaces… Expand
Meridiani Planum and the global hydrology of Mars
TLDR
It is demonstrated that Meridiani is one of the few regions of currently exposed ancient crust predicted to have experienced significant groundwater upwelling and evaporation, and the evaporite formation coincided with a transition to more arid conditions that increased the relative impact of a deep-seated, global-scale hydrology on the surface evolution.

Evidence for Amazonian acidic liquid water on Mars—A reinterpretation of MER mission results
The Mars Exploration Rover (MER) missions have confirmed aqueous activity on Mars. Here we review the analyses of the field-based MER data, and conclude that some weathering processes in MeridianiExpand
Sedimentary textures formed by aqueous processes, Erebus crater, Meridiani Planum, Mars
New observations at Erebus crater (Olympia outcrop) by the Mars Exploration Rover Opportunity between sols 671 and 735 (a sol is a martian day) indicate that a diverse suite of primary andExpand
Contrasting styles of water-rock interaction at the Mars Exploration Rover landing sites
The nature of ancient hydrological systems on Mars has been the subject of ongoing controversy, driven largely by a disconnect between observational evidence for flowing water on the Martian surfaceExpand
Exploration of Victoria Crater by the Mars Rover Opportunity
TLDR
Analysis of rocks in the walls of Victoria reveals that the aqueous alteration processes that operated at Eagle and Endurance also acted at Victoria, and sedimentary layering in the crater walls preserves evidence of ancient windblown dunes. Expand
Sulphate clastic injectites at Sinus Meridiani on Mars
Abstract Based on stratigraphic sections, the 1500 m-thick sulphate-based “Sinus Meridiani complex” appears to be composed of a superposition of three lithologically similar stratigraphic units, eachExpand
A case for ancient springs in Arabia Terra, Mars.
TLDR
There is a case can be made that several structures in Vernal Crater, Arabia Terra are ancient springs, and this interpretation is based on comprehensive geomorphologic analysis coupled with assessment of multiple hypotheses. Expand
Hematitic concretions at Meridiani Planum, Mars: Their growth timescale and possible relationship with iron sulfates
Using diffusion-based models for concretion growth, we calculate growth times of hematitic concretions that have been found in the Burns formation at Meridiani Planum, Mars, by NASA's OpportunityExpand
Meridiani Planum sediments on Mars formed through weathering in massive ice deposits
Although a number of hypotheses have been put forward to explain the sulphate deposits discovered by the Opportunity rover at Meridiani Planum, Mars, the sedimentary layers remain enigmatic. AExpand
Sulfate-Rich Eolian and Wet Interdune Deposits, Erebus Crater, Meridiani Planum, Mars
This study investigates three bedrock exposures at Erebus crater, an ~ 300 m diameter crater approximately 4 km south of Endurance crater on Mars. These outcrops, called Olympia, Payson, and Yavapai,Expand

The Opportunity Rover's Athena Science Investigation at Meridiani Planum, Mars
TLDR
The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum, and the rocks are interpreted to be a mixture of chemical and siliciclastic sediments formed by episodic inundation by shallow surface water, followed by evaporation, exposure, and desiccation.

TLDR
The geologic record at Meridiani Planum suggests that conditions were suitable for biological activity for a period of time in martian history. Expand

An astrobiological perspective on Meridiani Planum
Sedimentary rocks exposed in the Meridiani Planum region of Mars record aqueous and eolian deposition in ancient dune and interdune playa-like environments that were arid, acidic, and oxidizing. OnExpand
Impact origin of sediments at the Opportunity landing site on Mars
TLDR
A simple alternative explanation involving deposition from a ground-hugging turbulent flow of rock fragments, salts, sulphides, brines and ice produced by meteorite impact is presented, which can account for all of the features observed without invoking shallow seas, lakes or near-surface aquifers. Expand
A volcanic environment for bedrock diagenesis at Meridiani Planum on Mars
TLDR
An alternative model for diagenesis of Meridiani bedrock is proposed that involves deposition of volcanic ash followed by reaction with condensed sulphur dioxide- and water-bearing vapours emitted from fumaroles, which invokes an environment considerably less favourable for biological activity on Mars than previously proposed interpretations.
