The tantalizing prospect of a readable record of martian climatic variations has driven decades of work toward deciphering the stratigraphy of the martian polar layered deposits and understanding the role of the residual ice caps that cover them. Spacecraft over the past decade have provided a massive infusion of new data into Mars science. Polar science has benefited immensely due to the near-polar orbits of most of the orbiting missions and the successful landing of the Phoenix spacecraft in…

Orbital Forcing of Martian Climate Revealed in a South Polar Outlier Ice Deposit

Deciphering paleoclimate on Mars has been a driving goal of Martian science for decades. Most research has addressed this issue by studying Mars' large polar layered deposits (PLDs) as a paleoclimate

Planetary polar explorer – the case for a next-generation remote sensing mission to low Mars orbit

We propose the exploration of polar areas on Mars by a next-generation orbiter mission. In particular, we aim at studying the seasonal and regional variations in snow-deposits, which – in combination

Stratigraphic and Isotopic Evolution of the Martian Polar Caps From Paleo‐Climate Models

Exposed scarps images and ice‐penetrating radar measurements in the North Polar Layered Deposits (NPLD) of Mars show alternating layers that provide an archive of past climate oscillations, that are

A revised surface age for the North Polar Layered Deposits of Mars

The North Polar Layered Deposits (NPLD) of Mars contain a complex stratigraphy that has been suggested to retain a record of past eccentricity‐ and obliquity‐forced climate changes. The surface

Remnant Massifs of Layered Deposits at High Northern Latitudes of Mars

Ice deposits of the permanent northern polar cap of Mars exhibit a clearly expressed layered structure connected with consecutive accumulation of a solid phase of H2O (ice) with different impurity

High-Resolution Stratigraphy of the Mars North Polar Layered Deposits

The Mars north polar layered deposits (NPLD) consist primarily of water ice and dust, and represent the bulk of the north polar cap [Byrne, 2009]. The NPLD likely hold the most extensive record of

SHARAD Observations of Temporal Variations of CO2 Ice Deposits at the South Pole of Mars

Mars’s polar regions are covered by kilometers-thick layered deposits which carry a record of the planet’s climate history. The deposition and volatilization of the shallow CO2 deposits in the south

Polar deposits of Mars

Layered deposits unique to the poles of Mars indicate long-term winter deposition of ice and sediment modulated by periodic climate change. The layered deposits contain at least two kinds of

Mars North Polar Deposits: Stratigraphy, Age, and Geodynamical Response

TLDR
The Shallow Radar (SHARAD) on the Mars Reconnaissance Orbiter has imaged the internal stratigraphy of the north polar layered deposits of Mars, revealing a laterally continuous deposition of layers which typically consist of four packets of finely spaced reflectors separated by homogeneous interpacket regions of nearly pure ice.

An Inventory of Impact Craters on the Martian South Polar Layered Deposits

The polar layered deposits (PLD) of Mars continue to be a focus of study due to the possibility that these finely layered, volatile-rich deposits hold a record of recent eras in Martian climate

North polar stratigraphy and the paleo-erg of Mars

An accurate self-consistent way of coregistering the imaging and topographic data sets of the Mars Global Surveyor mission was developed and used to begin a stratigraphic analysis of the northern

Geology and insolation-driven climatic history of Amazonian north polar materials on Mars

TLDR
The history of geologic materials and features in the north polar region that span the Amazonian period are mapped and shown, suggesting generally higher obliquity and insolation conditions at the poles than at present.

The state and future of Mars polar science and exploration.

TLDR
The current state of Mars polar research is assessed, the key questions that motivate the exploration of the polar regions are identified, the extent to which current missions will address these questions are discussed, and what additional capabilities and investigations may be required to address the issues that remain outstanding are speculated.

Density of Mars' South Polar Layered Deposits

TLDR
The results demonstrate that the deposits of south polar layered deposits are probably composed of relatively clean water ice and also refine the martian surface-water inventory.

Recent ice ages on Mars

TLDR
Evidence is shown that dusty, water-ice-rich mantling deposits on Mars formed during a geologically recent ice age that occurred from about 2.1 to 0.4 Myr ago, a key pacemaker of ice ages on the Earth.

PFS-MEX observation of ices in the residual south polar cap of Mars

Accumulation and Erosion of Mars' South Polar Layered Deposits

TLDR
The sounding radar SHARAD on the Mars Reconnaissance Orbiter mapped detailed subsurface stratigraphy in the Promethei Lingula region of the south polar plateau, Planum Australe, indicating recent erosion of ice-rich layered deposits.
