A key pacemaker of ice ages on the Earth is climatic forcing due to variations in planetary orbital parameters. Recent Mars exploration has revealed dusty, water-ice-rich mantling deposits that are layered, metres thick and latitude dependent, occurring in both hemispheres from mid-latitudes to the poles. Here we show evidence that these deposits formed during a geologically recent ice age that occurred from about 2.1 to 0.4 Myr ago. The deposits were emplaced symmetrically down to latitudes of…

Dynamics of ice ages on Mars

TLDR
Simulations of the retreat and growth of ground ice as a result of sublimation loss and recharge reveal forty major ice ages over the past five million years of Mars, and how the subsurface ice sheets could have evolved to the state in which the authors see them today is explained.

Mars in ice ages for ∼25% of post-Noachian geologic history

An ice age recorded in the polar deposits of Mars

TLDR
Detailed analysis of observational data is presented showing that ~87,000 cubic kilometers of ice have accumulated at the poles since the end of the last ice age ~370,000 years ago; this volume is equivalent to a global layer of ~60 centimeters.

A recent ice age on Mars: Evidence for climate oscillations from regional layering in mid‐latitude mantling deposits

Two end‐member hypotheses have been proposed to account for the emplacement and distribution of ice in the near‐subsurface of Mars at mid to high latitudes during recent spin‐axis/orbital…

Preservation of Midlatitude Ice Sheets on Mars

Excess ice with a minimum age of tens of millions of years is widespread in Arcadia Planitia on Mars, and a similar deposit has been found in Utopia Planitia. The conditions that led to the formation…

Recent ice-rich deposits formed at high latitudes on Mars by sublimation of unstable equatorial ice during low obliquity

TLDR
Using the ice accumulation rates estimated from global climate model simulations, it is shown that, over the past ten million years, large variations of Mars' obliquity have allowed the formation of such metres-thick, sedimentary layered deposits in high latitude and polar regions.

An extended period of episodic northern mid-latitude glaciation on Mars during the Middle to Late Amazonian: Implications for long- term obliquity history

Mars is the only planet other than Earth in the Solar System that has a preserved nonpolar geological record of glaciation on its surface. Nonpolar ice deposits on Mars have been linked to variations…

Recent Ice Ages on Mars: The role of radiatively active clouds and cloud microphysics

Global climate models (GCMs) have been successfully employed to explain the origin of many glacial deposits on Mars. However, the latitude‐dependent mantle (LDM), a dust‐ice mantling deposit that is…

Wet-based glaciation on Mars

Mars is a glacial planet. It hosts water ice in large polar ice caps, and in thousands of ‘viscous flow features’ in its mid latitudes that are thought to be debris-covered water ice glaciers. These…

The distribution and behavior of Martian ground ice during past and present epochs

Mars undergoes significant oscillations in its orbit, which will have a pronounced effect on its climate and, in particular, on the behavior of subsurface water ice. We explore and map the behavior…

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.

Formation of Recent Martian Debris Flows by Melting of Near-Surface Ground Ice at High Obliquity

TLDR
It is shown that these gullies on Mars may result from the melting of water ice in the top few meters of the martian subsurface at high obliquity, and that above-freezing temperatures can occur in the near surface of Mars, but are only predicted at latitudes and for slope orientations corresponding to where the gullies have been observed on Mars.
