Mars Colors Explained: ESA Image Analysis
- A new satellite image from the European Space Agency (ESA) shows the diverse colors of Mars.
- the high-resolution camera on ESA's Mars Express orbiter captured the image of Arcadia Planitia, an area northwest of the solar system's tallest volcanoes.
- The image reveals four dust devils, columns of wind that form when the Martian surface warms the air above it, causing it to rise and pull dust.

Mars Express Captures Earth-Toned Surface of Arcadia Planitia
Updated June 27, 2025
A new satellite image from the European Space Agency (ESA) shows the diverse colors of Mars. The Mars Express orbiter captured the swirling yellows, oranges, and browns of Arcadia Planitia, a region critical to research about the planet’s past and its potential to house humans in the future.The image also reveals an impact crater and four dust devils traversing the region.
the high-resolution camera on ESA’s Mars Express orbiter captured the image of Arcadia Planitia, an area northwest of the solar system’s tallest volcanoes. the area is significant because solidified lava flows, no more than 3 billion years old, cover it. Scientists believe water ice exists close to the surface, making it a key area for future mars missions, according to the ESA.

The image reveals four dust devils, columns of wind that form when the Martian surface warms the air above it, causing it to rise and pull dust. The dust devils appear as whitish puffs near the center of the image.
An impact crater,measuring 9 miles (15 kilometers) across,sits in the bottom right corner of the photo. The layered material around the crater suggests the ground contained water ice during impact. The crater’s lack of erosion indicates it formed relatively recently.
The image may appear blurry due to wind picking up and carrying particles of debris from the planet’s surface, creating a visual haze.
The wind also forms yardangs, ridges created when wind erodes vulnerable rock, leaving resistant rock standing. A purplish-brown terrain, with a high concentration of silicates and a low concentration of iron, lies below the red section. Differences in sand properties, like density and size, affect how grains accumulate and travel across Mars, contributing to the color variations.
What’s next
Future missions to Mars may focus on Arcadia Planitia to explore its water ice deposits and assess its potential for human habitation.
