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

THEMIS: Double impact at Buvinda Vallis
THEMIS Image of the Day, August 10, 2018. Today’s VIS image shows a portion of Buvinda Vallis, a channel near the flank of Hecates Tholus. The closeness of the volcano suggests that the channel was eroded by a lava flow, … Continue reading

HiRISE: Flow over a crater rim in Daedalia Planum
A flow over a crater rim in far eastern Daedalia Planum. Lava flow over-topped crater rim and some lava poured down crater wall. Perhaps it is possible to use knowledge of crater rim, wall (slope), etc., as well as lava … Continue reading

THEMIS: Daedalia Planum crater
THEMIS Image of the Day, July 30, 2018. This VIS image shows part of an unnamed crater on the northwest margin of Daedaia Planum. Lava flows are visible around the crater rim. The interior of the crater has been filled … Continue reading

HiRISE: This is not the hydrothermal deposit you’re looking for
A hotspot for exploration on Mars centers on areas that were once, or are currently, next to a significant source of heat such as volcanoes. Martian volcanoes have not been active for the last couple million years, but beneath the … Continue reading

THEMIS: Lava flow dodges impact crater’s ejecta
THEMIS Image of the Day, July 26, 2018. This VIS image shows a small portion of the vast lava flow field of Daedalia Planum. The flows originate at Arsia Mons, the youngest of the three Tharsis volcanoes. See more THEMIS … Continue reading

HiRISE: Cored island
Cored island. This channel may have been used by both lava and water. One of the processes produced a crater-cored island and later, the downstream side was eroded away, leaving knobs and an inverted streamlined form. Beautiful Mars series. [More … Continue reading

THEMIS: Winding channels of Elysium Fossae
THEMIS Image of the Day, July 16, 2018. Today’s VIS image shows part of one of the Elysium Fossae on the western flank of the Elysium volcanic complex. The fossae have both a tectonic and volcanic origin. The linear fractures, … Continue reading

HiRISE: Lava-coated craters
Lava-coated craters. The larger crater looks normal–dimpled depression with a protruding rim barely covered by lava which later deflated. The smaller depression looks deeper and steeper-sided, and the rim does not protrude, so it is probably below the level of … Continue reading
