ESA’s Mars Express spacecraft has captured striking new images of Mars’ Utopia Planitia region, revealing a surface now largely covered in dark volcanic ash where the planet’s traditional reddish hue once dominated.
The images, taken in November 2024 and released by the European Space Agency on April 16, 2026 (local time), demonstrate a dramatic transformation compared to observations made decades ago. Viking mission data from 1976 indicated significantly less ash distribution in the same area, highlighting the rapidity of the change.
According to ESA, the shift may result from strong Martian winds removing surface dust layers, thereby exposing underlying volcanic deposits. Mars, home to Olympus Mons—the largest volcano in the solar system—has a long volcanic history, with major eruptions occurring billions of years ago followed by more gradual lava activity in later periods.
The visual contrast is stark: dark ash now blankets wide expanses of the terrain, creating a divided appearance across the landscape. While such geological shifts typically unfold over millions of years, this alteration has become evident within just a few decades.
