Mars Express Delivers Ultra-High-Res View of a 1,300-km Martian Flood Channel

ESA’s Mars Express released high-resolution imagery of Shalbatana Vallis, a 1,300-km channel on Mars formed by ancient groundwater floods about 3.5 billion years ago. The new views reveal chaotic terrain, wrinkle ridges, volcanic ash deposits, buried craters, and other geological details that shed light on Mars’s watery past and the possibility of ancient oceans near Chryse Planitia. The mission has mapped the planet in detail since 2003 and is expected to continue operations through 2034.

ESA Image Reveals Volcanic Ash Lining an Ancient Martian Waterway

ESA’s Mars Express released a high-resolution view of Shalbatana Vallis, a nearly 1,300 km long Martian channel once carved by flowing water. The image shows dark volcanic ash concentrated along the valley floor, likely carried by winds, with hints of buried ice and subsidence shaping the landscape. The findings illustrate how Mars’ ancient hydrology and volcanic activity coexisted, leaving a rich record for studying its past climate and potential habitability.

Mars Express Detects Rapid Dark Patch Spreading Across Utopia Planitia

ESA's Mars Express images show a fast-growing dark ash blanket spreading across the Utopia Planitia basin, possibly from volcanic ash or winds removing ochre dust. The patch, made of mafic minerals like olivine and pyroxene, has expanded hundreds of kilometres in under 50 years, far quicker than typical Martian surface changes.

Martian Surface Collapses

The European Space Agency's Mars Express has provided new detailed images of the Acheron Fossae region on Mars, revealing a complex landscape of deep cracks, valleys filled with ice-rich rock, and transitional plains, offering insights into the planet's geological history and climate fluctuations over billions of years.
