The large-area coverage at a resolution of 10–20 metres per pixel in colour and three dimensions with the High Resolution Stereo Camera Experiment on the European Space Agency Mars Express Mission has made it possible to study the time-stratigraphic relationships of volcanic and glacial structures in unprecedented detail and give insight into the geological evolution of Mars. Here we show that calderas on five major volcanoes on Mars have undergone repeated activation and resurfacing during the…

Recent Activity on Mars: Fire and Ice
Written by Linda M. V. Martel Hawai'i Institute of Geophysics and Planetology Scientists combined the time-honored method of counting craters to estimate the age of planetary surfaces with brand new
Discovery of a flank caldera and very young glacial activity at Hecates Tholus, Mars
TLDR
New image and topographic data from the High Resolution Stereo Camera reveal previously unknown traces of an explosive eruption on the northwestern flank of the shield volcano Hecates Tholus, meaning that large-scale explosive volcanism on Mars was not confined to the planet's early evolution.
Tropical to mid-latitude snow and ice accumulation, flow and glaciation on Mars
Images from the Mars Express HRSC (High-Resolution Stereo Camera) of debris aprons at the base of massifs in eastern Hellas reveal numerous concentrically ridged lobate and pitted features and
The volcanic history of Mars: High-resolution crater-based studies of the calderas of 20 volcanoes
Abstract Determining absolute surface ages for bodies in the Solar System is, at present, only possible for Earth and Moon with radiometric dating for both bodies and biologic proxies such as fossils
Quantifying geological processes on Mars - Results of the high resolution stereo camera (HRSC) on Mars express
This review summarizes the use of High Resolution Stereo Camera (HRSC) data as an instrumental tool and its application in the analysis of geological processes and landforms on Mars during the last
Debris-covered piedmont glaciers along the northwest flank of the Olympus Mons scarp: Evidence for low-latitude ice accumulation during the Late Amazonian of Mars
We use Viking and new MGS and Odyssey data to characterize the lobate deposits superimposed on aureole deposits along the west and northwest flanks of Olympus Mons, Mars. These features have
Thermal history of Mars inferred from orbital geochemistry of volcanic provinces
TLDR
Geochemical data derived from the Gamma Ray Spectrometer on board NASA's Mars Odyssey spacecraft is presented, focusing on twelve major volcanic provinces of variable age, revealing clear trends in composition that are found to be consistent with varying degrees of melting of the martian mantle.
Late-stage water eruptions from Ascraeus Mons volcano, Mars: Implications for its structure and history
Abstract Ascraeus Mons was one of the first of the Martian volcanoes to be imaged by the High Resolution Stereo Camera (HRSC) experiment onboard the ESA Mars Express spacecraft. These images show
Planetary science: Picturing a recently active Mars
TLDR
The evaluation of the first six months of data from the high-resolution stereo camera on board ESA's Mars Express probe reveals evidence for a frozen sea similar in area and depth to the North Sea on Earth, and some 5 million years old.
The global martian volcanic evolutionary history
Abstract Viking mission image data revealed the total spatial extent of preserved volcanic surface on Mars. One of the dominating surface expressions is Olympus Mons and the surrounding volcanic

Evidence from the Mars Express High Resolution Stereo Camera for a frozen sea close to Mars' equator
TLDR
High Resolution Stereo Camera images from the Mars Express spacecraft indicate that evidence is consistent with a frozen body of water, with surface pack-ice, around 5° north latitude and 150° east longitude in southern Elysium, which is a place that might preserve evidence of primitive life, if it has ever developed on Mars.
Volcanism on Mars
More than 15 years of planetary exploration of Mars have given insight into the geologic processes that have shaped its surface. The newly acquired Viking data have shown that volcanism is one of the
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.
Explosive volcanism on Hecates Tholus, Mars - Investigation of eruption conditions
Evidence is presented supporting the identification of a discrete, well-preserved air fall deposit generated by explosive volcanism on Mars. The deposit is located immediately to the west of the

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
Evidence for recent volcanism on Mars from crater counts
Impact craters help characterize the age of a planetary surface, because they accumulate with time. They also provide useful constraints on the importance of surface erosion, as such processes will
Perennial water ice identified in the south polar cap of Mars
TLDR
This work presents the first direct identification and mapping of both carbon dioxide and water ice in the martian high southern latitudes, at a resolution of 2 km, during the local summer, when the extent of the polar ice is at its minimum.
Mars and Earth: Comparison of cold-climate features
Abstract On Earth, glacial and periglacial features are common in areas of cold climate. On Mars, the temperature of the present-day surface is appropriate for permafrost, and the presence of water
