Ascreaus Mons Flank (THEMIS_IOTD_20250520a)

This VIS image shows a cross section of the eastern flank of Ascraeus Mons. Ascreaus Mons is the northernmost volcano of the three large Tharsis volcanoes. In order from north to south the volcanoes are Ascreaus Mons, Pavonis Mons and Arsia Mons. All three volcanoes form a line located along a tectonic bulge caused by extensional forces in the region. Along this trend there are increased tectonic features, collapse features, and additional lava flows that arose from the flanks of the volcanoes rather than just the summit. Like the other large volcanoes in the region, Ascraeus Mons is a shield volcano. Shield volcanoes are formed by lava flows originating near or at the summit, building up layers upon layers of lava. In shield volcanoes summit calderas are typically formed where the surface collapses into the void formed by an emptied magma chamber. Ascraeus Mons is the largest of the three volcanoes with a summit of 18km (11 miles) and a width of 460 km (286 miles). For comparison Mauna Kea - the tallest volcano on Earth - is 10.2 km tall (6.3 mi) measured from the base on the sea floor.

Ascraeus Mons Summit (THEMIS_IOTD_20240401a)

This VIS image shows part of the summit of Ascraeus Mons. Ascraeus Mons is the northernmost and tallest of the three large aligned Tharsis volcanoes. Calderas are found at the tops of volcanoes and are the source region for magma that rises from an underground lava source to erupt at the surface. Volcanoes are formed by repeated flows from the central caldera. The final eruptions can pool within the summit caldera, leaving a flat surface as they cool. Calderas are also a location of collapse, creating rings of tectonic faults that form the caldera rim. Ascraeus Mons has several caldera features at its summit. Ascraeus Mons is 18 km (11 miles) tall, for comparison Mauna Kea - the tallest volcano on Earth - is 10 km tall (6.2 miles, measured from the base below sea level).

Perspective view of Mars’s Tharsis volcanoes

This oblique perspective view shows a slice of Mars imaged to mark a milestone for ESA’s Mars Express: its 25 000th orbit around the Red Planet.

It was generated from a digital terrain model and the nadir (downward-pointing) and colour channels of Mars Express’s High Resolution Stereo Camera. The vertical scale is exaggerated by a factor of approximately three, making the volcanoes look three times higher than they are in real life.

Three of Mars’s famously colossal volcanoes are shown here: from left to right, Arsia, Pavonis and Ascraeus Mons. The mound of Mars’s largest volcano, Olympus Mons, can be spied further away at the top of the frame, while the fractured terrain of Noctis Labyrinthus, Mars’s ‘labyrinth of night’, can be seen in the foreground.

New Mars Express image celebrates 25 000 orbits (labelled)

This image from ESA’s Mars Express shows a slice of Mars imaged to mark a milestone for ESA’s Mars Express: its 25 000th orbit around the Red Planet. The stunning view shows volcanoes, valleys, craters, clouds, and even a flying visit from Mars's largest moon, Phobos.

Numerous labels have been placed across the terrain, highlighting features and regions of note. Be sure to zoom in to explore the landscape in detail!

This image comprises data gathered by Mars Express’s High Resolution Stereo Camera (HRSC) on 19 October 2023 during orbit 25 000. It was created using data from the nadir channel, the field of view aligned perpendicular to the surface of Mars, and the colour channels of the HRSC. The ground resolution is <450 m/pixel and the image is centred at about 2°N/248°E.

[Image description: This image shows a large, tan-coloured slice of Mars, with the curvature of the planet visible at the top and bottom of the frame. Cutting diagonally right to left across the centre of the planet like a belt are three darker raised patches (volcanoes). Many other features are visible across the frame, including scarred terrain, clouds, and the moon Phobos, which can be seen as a dark, irregular blob to the lower left.]

Topography and context of Tharsis and surroundings

This colour-coded image shows the location and topography of a slice of Mars imaged to mark a milestone for ESA’s Mars Express: its 25 000th orbit around the Red Planet.

The area outlined by the diagonal rectangular box indicates the area imaged by Mars Express on 19 October 2023. The globe view is based on a digital terrain model of the region, from which the topography of the landscape can be derived. Lower parts of the surface are shown in blues and purples, while higher altitude regions show up in whites and reds, as indicated on the scale at the bottom. The ground resolution is <450 m/pixel and the image is centred at about 2°N/248°E.

Valles Marineris and Tharsis by jccwrt

Valles Marineris and Tharsis

Mars' Tharsis region and Valles Marineris imaged by Mars Express HRSC. This image, taken shortly after the northern hemisphere's summer solstice, captures the planet's Aphelion Cloud Belt near peak density. The cloud belt forms when the planet is furthest from the Sun, when lower atmospheric temperatures cause the condensation temperature for water ice crystals to fall to altitudes with more water vapor. The aphelion cloud belt is generally thickest over the high terrain of the Tharis volcanic region.

Olympus Mons is visible at far left, near the horizon. A small windstorm is present near its summit, lifting large dust clouds. A large orographic cloud is visible on the western slopes of Ascraeus Mons (top left/center). Pavonis Mons (left center) and the northern flanks of Arsia Mons are visible in a line just below it.

The large canyon system of Valles Marineris dominates the left side of the image. This gigantic canyon system formed due to the immense weight of the large shield volcanoes to its west. The weight of these volcanoes pushes down on the planet's interior, causing the landscape to swell and buckle in the region of Valles Marineris.

This image was taken during Mars Express' 24,725th orbit of Mars, on August 1, 2023.
