Mantle plumes still active under Tharsis, Elysium?
[Editor’s note: From a paper by A.-C. Plesa and eight co-authors recently published in Geophysical Research Letters.] The thermal state and interior structure of Mars We constrain the thermal state and interior structure of Mars by combining a large number … Continue reading

HiRISE: Pitted material and mounds
Pitted material and mounds in Chryse Planitia. This rough-looking material has many meter-length pits. What exactly is this stuff? Chryse Planitia shows evidence of water erosion in the past, and is the bottom end for many outflow channels from the southern … Continue reading

Olympus Mons and Ascraeus Mons: Geologically recent lava inflation
The summit of Olympus Mons displays lava flows, some of which are truncated by the caldera, that appear to have flowed uphill. Because lava flows downhill, this mismatch between the flow direction and present-day topography suggests that the terrain has … Continue reading
THEMIS: High on the east flank of Pavonis Mons
THEMIS Image of the Day, October 11, 2018. This false-color VIS image shows the eastern flank of Pavonis Mons. The darker streaks are created by wind action, and the curving lines are faults produced when the volcano “relaxed” under the … Continue reading

THEMIS: Intersecting lava channels & tectonics
THEMIS Image of the Day, August 27, 2018. The Tharsis region contains both large volcanoes and extensive lava plains. Most of the channel features in this region were formed by the flow of lava rather than the flow of water. … Continue reading
THEMIS: Impact crater on volcanic plains
THEMIS Image of the Day, August 23, 2018. This VIS image shows an unnamed crater located northeast of Ascraeus Mons, on the volcanic plains of the Tharsis region. The rim has several concentric ridges. There are multiple layers of ejecta, … Continue reading

THEMIS: Big step-off at Olympus Rupes
THEMIS Image of the Day, August 20, 2018. Olympus Rupes is the name of the large escarpment surrounding Olympus Mons. The escarpment is a cliff where there is a large elevation change over a short distance. The elevation change from … Continue reading

HiRISE: Source of flow east of Olympus Mons
Source of flow to the east of Olympus Mons. Here we see part of a linear depression with branching segments in Amazonian volcanic plains east of Olympus Mons. The flow source from this feature that exhibit volcanic and/or fluvial characteristics. … Continue reading
