Spacecraft spots mesmerizing swirls at one of the lowest points on Mars
The curving patterns — found inside one of the largest impact craters in the solar system — have a puzzling origin.

This story is part of Welcome to Mars, our series exploring the red planet.
Try to comprehend the scale of the Hellas impact basin on Mars. At 1,430 miles (2,300 kilometers) in diameter and 4.3 miles (7 kilometers) deep, it’s a doozy of a crater, one of the largest we know of in the solar system. It’s an epic region on Mars, but it gets even more interesting when you zoom in on the details of its landscape.
On Friday, the European Space Agency shared a view snapped by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter back in May. It shows a wild wonderland of swirls and curves the space agency described as «mesmerizing.»
ESA traces the history of Hellas back to between 3.8 and 4.1 billion years ago when an asteroid struck the planet. Visit ESA for the full, detailed image and spend some time getting lost in the dramatic whorls, like an elongated fingerprint etched across the Martian ground.
The stretch of surface seen in the image is one of the lowest points on Mars. «The swirling nature of the landscape evokes a feeling of flow,» ESA said in a statement. «The exact reason for its origin is a puzzle, however, and could be attributed to one of many different processes: salt tectonism, or viscous deformation of ice and sediments, for example.»
The Trace Gas Orbiter spacecraft has been studying the red planet and cataloging its atmospheric gases. It’s one facet of the ExoMars program, which will also involve sending a rover to Mars in 2022. The rover, like the orbiter, is a joint project from ESA and Russian space agency Roscosmos.
We’ve seen some other wild views from inside Hellas, including a look at «scratch marks,» likely created by dry ice sliding down sandy dunes — as seen by NASA’s Mars Reconnaissance Orbiter.
The questions around the impact basin formations show we still have a lot to learn about the red planet. We might have rovers on the surface and spacecraft in orbit, but there are plenty of mysteries left to solve.

Amazon’s Delivery Drivers Will Soon Wear AI Smart Glasses to Work
The goal is to streamline the delivery process while keeping drivers safe.
Amazon announced on Wednesday that it is developing new AI-powered smart glasses to simplify the delivery experience for its drivers. CNET smart glasses expert Scott Stein mentioned this wearable rollout last month, and now the plan is in its final testing stages.
The goal is to simplify package delivery by reducing the need for drivers to look at their phones, the label on the package they’re delivering and their surroundings to find the correct address.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
A heads-up display will activate as soon as the driver parks, pointing out potential hazards and tasks that must be completed. From there, drivers can locate and scan packages, follow turn-by-turn directions and snap a photograph to prove delivery completion without needing to take out their phone.
The company is testing the glasses in select North American markets.
Watch: See our Instagram post with a video showing the glasses
A representative for Amazon didn’t immediately respond to a request for comment.
To fight battery drain, the glasses pair with a controller attached to the employee’s delivery vest, allowing them to replace depleted batteries and access operational controls. The glasses will support an employee’s eyeglass prescription. An emergency button will be within reach to ensure the driver’s safety.
Amazon is already planning future versions of the glasses, which will feature «real-time defect detection,» notifying the driver if a package was delivered to the incorrect address. They plan to add features to the glasses to detect if pets are in the yard and adjust to low light.
