Why does Mars look purple, yellow and orange in ESA's stunning new satellite image?

Despite being known as the Red Planet, Mars shows off its swirling yellows, oranges and browns in a new satellite photo from the European Space Agency (ESA). The Earth-toned surface also reveals an impact crater and four sneaky dust devils making their way across the region. The Rothko-like image was taken by a high-resolution camera on ESA's Mars Express orbiter and captures Arcadia Planitia, an area of Mars critical to research about the planet's past and its potential to house humans in the future. Northwest of the tallest volcanoes in the solar system, Arcadia Planitia is a region of intrigue. It's laden with solidified lava flows that are, at most, 3 billion years old. The area is also thought to host water ice close to the planet's surface, making it an area of interest when planning future missions to Mars, according to a statement from ESA. Arcadia Planitia is home to visiting "dust devils," short-lived columns of wind akin to small tornadoes. Dust devils form when the Martian surface warms the air just above it, leading the air to rise and pulling dust with it. The new image shows four dust devils as they snake their way across the plains of the region. Easy to overlook, you can spot them as whitish puffs of dust near the center of the image, straddling the boundary between the darker brown and lighter red parts of the plain. A large impact crater sits in the bottom right corner of the photo and measures 9 miles (15 kilometers) across, according to ESA. The formation of layered material around the crater is evidence that the ground encompassed notable amounts of water ice during impact, and lack of clear erosion of the crater dates it to relatively recently on the geological timeline. Related: Perseverance rover spots peculiar 'spider egg' rock on Mars — and scientists have no idea how it got there If you noticed that the image is blurry, you're discerning an effect of the wind on Mars. Gusts of air pick up and carry tiny particles of debris from the planet's surface, which creates a minor visual haze.

The red region is covered in ridges called "yardangs," which are formed when wind erodes vulnerable rock and leaves the most resistant rock still standing. Below the red section is purplish-brown terrain, which has a high concentration of silicates and a low concentration of iron, the statement notes. The difference in colors also stems from properties of the sand, like density and size, which affect how the grains accumulate and travel across Mars.

Media Advisory - Energy Sector Gains New Edge in Vegetation and Methane Emissions Monitoring with Maxar and Satelytics Partnership
PERRYSBURG, Ohio, June 25, 2025 (GLOBE NEWSWIRE) -- Maxar and its partner Satelytics are announcing today an expansion of their offerings to the energy industry. In addition to the methane monitoring solution that has been on the market for several years, Satelytics is now introducing a vegetation encroachment solution that leverages Maxar's very high-resolution satellite imagery. Monitoring vegetation growth along utility lines and pipelines Caption: Satelytics' vegetation monitoring product leverages Maxar's very high-resolution satellite imagery to identify vegetation, like the coniferous tree in the above screenshot, that could possibly fall on electrical distribution networks. This alert enables a utility company to go into the field and mitigate specific vegetation issues instead of spending time monitoring the whole transmission line from a truck. Satelytics will generate risk profiles of vegetation in and around customer assets using mono- and stereo-imagery collections from the Maxar constellation, including the recently launched WorldView Legion satellites. This solution will lean on Maxar's collection capability of 6 million sq km of capacity per day, which significantly outpaces any other commercial provider. Monitoring vegetation growth along utility lines or pipelines with Maxar's 30 cm-class resolution satellite imagery and Satelytics' value-added insights allows an energy company to prioritize sending ground crews to specific locations that are known to need trimming maintenance instead of having ground crews drive the entire lengths of lines, which can be hundreds of miles in distance. This targeted vegetation maintenance allows the energy company to reduce search time and increase efficiency of field crews, proactively identify and address potential threats outside the immediate corridor, verify completed work and optimize contractor management, and improve overall grid reliability by reducing vegetation-related outages. 'Maxar's recently expanded capacity with the new WorldView Legion satellites creates new opportunities for us to reliably collect fresh, very high-resolution satellite imagery along our customers' rights-of-way to analyze for vegetation encroachment. Our customers will benefit from the high-quality of Maxar's imagery as value-added products like our vegetation risk assessments improve with better input data.' — Sean Donegan, President and Chief Executive Officer of Satelytics Producing methane detection alerts Maxar's WorldView-3 satellite hosts a shortwave infrared (SWIR) sensor that collects imagery in wavelengths outside what the human eye can see. Satelytics uses this SWIR sensor to create a methane detection and measurement product for energy companies. Duke Energy's Piedmont Gas division, a local distribution company that operates in the Midwest and Southeast U.S., uses Satelytics' methane solution to improve operational efficiency, safety and reporting by quickly finding leaks, repairing them and reducing emissions across a five-state service territory. Since the beginning of 2022, Duke Energy has reduced recordable leaks by over 85% using Satelytics' solution. To learn more about Satelytics' methane detection and quantification alerts, read their blog post. 'Satelytics has been innovating with Maxar's very high-resolution satellite imagery for nearly a decade, and we're excited to see them expand their offerings to include vegetation management for utilities. The quality, currency and accuracy of our data enables use cases that require precision to make informed decisions and Satelytics is taking it a step further with their energy industry-focused products.' — Todd Surdey, SVP and GM of Enterprise at Maxar Geospatial insights for informed monitoring and mitigationThe combined power of Maxar's high revisit, very high-resolution satellite imagery and Satelytics' AI-driven algorithms provides energy companies with early detection geospatial insights and alerts that enable informed decision-making and minimize environmental risks. About SatelyticsSatelytics is a software company producing geospatial analytics for early detection, location and — in many instances — quantification of our customers' most pressing challenges. The Ohio-based company uses science, software, and technology to deliver valuable services to customers to identify problems before they become disasters – environmentally, financially, or otherwise. About Maxar IntelligenceMaxar Intelligence is a leading provider of secure, precise geospatial insights. Operating the most advanced commercial Earth observation constellation in orbit, we use the power of very high-resolution satellite imagery and software technology to deliver mission success on Earth and in space.

North Korea Appears to Have Added to Its Nuclear Complex
North Korea appears to have constructed a new building within its main nuclear complex, satellite imagery showed, in what could be an additional enrichment facility to ramp of the country's ability to produce nuclear weapons. The new structure at Yongbyon, some 100 kilometers (62 miles) north of Pyongyang, resembles an enrichment facility at Kangson, another North Korean nuclear site near the capital, the satellite image analyzed by weapons expert Jeffrey Lewis showed.
