Image showing an advertisement for the "Planetary Geomorphology and Surface Processes" session at EGU 2026 (between 3-8 May 2026). Deadline for abstract submission is the 15th of January 2026. On the image you can see a large dark coloured dune field in a larger impact crater on Mars. Smaller impact craters are also visible on the image. List of conveners of the session is also given; Lonneke Roelofs, Stephen Brough, Lisanne Braat, Joe McNeil and Nikolaus Kuhn. A QR code is provided that links to the session's webpage: https://meetingorganizer.copernicus.org/EGU26/sessionprogramme/5864

Call for Abstracts 📣 Our session "Planetary Geomorphology and Surface Processes" - GM6.1, at the EGU (3-8 May 2026 in Vienna) will provide a platform for cross-planetary discussion on geomorphological and geological processes. Abstract deadline is January 15!

The image shows a circular (white) water ice deposit in a crater on Mars, which is around 12 km in diameter. The surrounding area outside of the crater is yellow in colour. In the upper left corner of the circular ice deposit a darker patch (dark grey) is visible. This patch contains dunes. In lower right half of the ice deposit layers can be recognized by faint, slightly grey lines.

The IAG #Planetary Gemorphology Image of the Month 📸 for May is now available. PhD candidate Marie Azevedo explains how the layers of different types of dusty ice deposits in Louth crater on #Mars tell us a story about the past. planetarygeomorphology.wordpress.com/2025/05/01/k...

A four panel image showing black and white photos of the surface of Enceladus. The surface of Enceladus is highly fractured and hosts a lot of craters. In the images, steep slopes around the geological structures are highlighted on which darker streaks are present.

‪The IAG #Planetary Gemorphology Image of the Month 📸 for April is now available. Undergraduate student Kyleshaquill Fred Velez takes us to Enceladus, an icy moon of Saturn, where mass wasting occurs on the steep slopes along tectonic features.

Two images of clouds on Mars. Left image: clouds and dust at the Northern Polar Region of Mars during the local spring (HRSC image). Right image: clouds and dust at the Northern Polar Region of Mars during the local winter (VMC image). The left panel shows a textured spiral dust storm (brownish) mixed with water ice clouds (bright white) (indicated by arrows). The right panel shows the North Polar Hood, a large scale water ice cloud system.
