Mars Express: From horizon to horizon
Fifteen years ago, ESA’s Mars Express was launched to investigate the Red Planet. To mark this milestone comes a striking view of Mars from horizon to horizon, showcasing one of the most intriguing parts of the martian surface. On 2 … Continue reading

HiRISE: All that the lava leaves behind
All that the lava leaves behind. There are streamlined and eroded forms in this lava channel, a region with very little HiRISE coverage. Beautiful Mars series. [More at links]

THEMIS: Volcanic fissure in Labeatis Fossae
THEMIS Image of the Day, May 8, 2018. The feature that crosses this VIS image is a graben. Graben are formed by tectonic action, where a block of material moves downward between a pair of faults. The northern part of … Continue reading

Perfect beaches ruined by martian volcanoes
The presence of potential shorelines in the northern hemisphere of Mars suggests that Mars once had oceans. The non-constant elevations of these putative shorelines, however, do not support that hypothesis. Recent work [published in Nature] by Robert Citron and colleagues … Continue reading

Mars’ oceans formed early, with a possible assist from volcanism
A new scenario seeking to explain how Mars’ putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million years earlier and were not as deep as once thought. The proposal [published … Continue reading

HiRISE: Diverse composition and stratigraphy in the Claritas Region
Diverse composition and stratigraphy in the Claritas Region. This region, west of Solis Planum, is a tectonic and volcanic area located south-east of the Tharsis volcano group (the Tharsis Montes) on the Tharsis rise. It extends roughly north to south … Continue reading

THEMIS: Chains of pit craters near summit of Arsia Mons volcano
THEMIS Image of the Day, January 4, 2018. The three large aligned Tharsis volcanoes are Arsia Mons, Pavonis Mons and Ascraeus Mons (from south to north). There are collapse features on all three volcanoes, on the southwestern and northeastern flanks. … Continue reading

THEMIS: Pits at caldera’s edge
THEMIS Image of the Day, January 3, 2018. This THEMIS image shows part of the caldera floor of Arsia Mons. It is not uncommon for calderas to have “flat” floors after the final explosive eruption the empties the subsurface magma … Continue reading
