Mars’ longtime polar mystery may have finally been solved
From the surface, Mars may seem like a dry, desert-like world lacking water, but a closer look at the planet’s poles will some striking structures: massive polar ice caps.
At the north pole, the ruddy terrain peeks through the ice, like zebra stripes. In the south pole lurks a mystery, a massive deposit of frozen carbon dioxide and water ice. Scientists have spent decades trying to understand how it formed and how it’s linked to the amount of carbon dioxide (CO2) in the Martian atmosphere.
A pair of scientists in the 1960s came up with a plausible theory, and now, decades later, a new study published in Nature Astronomy may have confirmed their findings.
The massive deposit — measuring 3,280 feet (1 kilometer) thick — contains sheets of water ice and carbon dioxide arranged in alternating layers, like a cake. It’s topped off with a thin frosting of carbon dioxide ice, and scientists noticed something interesting: the massive ice deposit contains as much carbon dioxide as the entire Martian atmosphere.
Peter Buhler, a planetary scientist at NASA’s Jet Propulsion Laboratory led the new study. The team used computer simulations to map out the ice, and they were surprised at how closely their models matched with what Robert B. Leighton and Bruce Murray predicted decades ago.
“Usually, when you run a model, you don’t expect the results to match so closely to what you observe,” he said in a statement. “But the thickness of the layers, as determined by the model, matches beautifully with radar measurements from orbiting satellites.”
The ice cap puzzled researchers because according to science, it shouldn’t exist. That’s because water ice is more thermally stable and darker than carbon dioxide ice, which means that it should destabilize when layered between water ice.
However, the new model explains this behavior. Buhler and his team say there are three reasons why the frozen carbon dioxide exists. First, Mars wobbles as it orbits the sun, and when it does, the slight changing of the tilt alters the amount of sunlight that hits the ice. Second, each type of ice reflects the sun a bit differently. And lastly, because of the exposure to sunlight, the carbon dioxide sublimates–meaning it goes directly from a solid to a gas–which alters the atmospheric pressure.
As Mars wobbles, the amount of sunlight reaching the ice varies, causing the ice to form and then later sublimate. When the carbon dioxide ice was forming, water ice would’ve been trapped with it. But when that ice sublimated, the more stable water ice would have remained behind, forming the layers we now see at the south pole.

Mars’ climate, just like Earth’s, has changed over millions of years. To that end, not all of the carbon dioxide ice was lost; some were left behind to build up the varying layers we see—a process that has altered the red planet’s atmospheric pressure.
This is what Leighton and Murray hypothesized back decades ago, and this is what Buhler’s new model shows.
“Our determination of the history of Mars’s large pressure swings is fundamental to understanding the evolution of Mars’s climate, including the history of liquid water stability and habitability near Mars’s surface,” Buhler said in a statement.
By understanding what processes formed the south polar ice cap, scientists can better understand more of what happened in Mars’ history.

Tesla adjusts Robotaxi safety monitor strategy in Austin with new service area
The positioning of the driver, as well as the driver’s hands being closer to the steering wheel, is more similar to what Tesla is doing in the Bay Area Robotaxi program than it is to what it has done in Austin.
Tesla has adjusted its Robotaxi safety monitor strategy in Austin after it expanded its service area in the city last week for the third time.
Tesla has been operating its Robotaxi platform in Austin since June 22. The vehicles have been operated without a driver, but Tesla has placed safety monitors in the passenger’s seat as a precaution.
The safety monitors are responsible for performing any necessary interventions and maintaining a safe and comfortable cabin for riders as they experience Tesla’s first venture into the driverless ride-sharing space.
Last week, Tesla expanded its service area in Austin for the third time, expanding it from about 90 square miles to 170 square miles. The expansion included new territory, including the Austin-Bergstrom International Airport, Tesla’s Gigafactory Texas, and several freeways.

The freeway is an area that is uncharted territory for the Tesla Robotaxi program, and this fact alone encouraged Tesla to switch up its safety monitor positioning for the time being.
For now, they will be riding in the driver’s seat when routes require freeway travel:

The positioning of the driver, as well as the driver’s hands being closer to the steering wheel, is more similar to what Tesla is doing in the Bay Area Robotaxi program than it is to what it has done in Austin.
This is sure to draw criticism from skeptics, but it is simply a step to keep things controlled and safe while the first Robotaxi drives take passengers on the highway with this version of the Full Self-Driving software.
This FSD version differs from the one that customers have in their own vehicles, but CEO Elon Musk has indicated something big is coming soon. FSD v14 is coming to vehicles in the near future, and Musk has said its performance is pretty incredible.

Tesla has best month ever in Turkey with drastic spike in sales
Tesla managed to sell 8,730 Model Y vehicles in Turkey, outpacing almost every competitor by a substantial margin. Only one brand sold better than Tesla in August in Turkey, and it was Renault.
Tesla had its best monthly performance ever in Turkey in August, thanks to a drastic spike in sales.
Tesla saw an 86 percent bump in sales of the new Model Y in Turkey in August compared to July, dominating the market.
The performance was one of Tesla’s best in the market, and the company’s sales for the month accounted for half of all EV sales in Turkey for August, as it dominated and led BYD, which was the second-best-selling brand with just 1,639 units sold.

Electric vehicles are, in some ways, more desirable than their gas counterparts in Turkey for several reasons. Most of the reasoning is financial.
First, EVs are subject to a lower Special Consumption Tax in Turkey. EVs can range from 25 percent to up to 170 percent, but this is less than the 70 to 220 percent rate that gas-powered vehicles can face. The tax is dependent on engine size.
Additionally, EVs are exempt from the annual Motor Vehicle Tax for the first ten years, providing consumers with a long-term ownership advantage. There are also credits that can amount to $30,000 in breaks, which makes them more accessible and brings down the cost of ownership.
Let’s not forget the other advantages that are felt regardless of country: cheaper fuel costs, reduced maintenance, and improved performance.
The base Model Y is the only configuration available in Turkey currently.

Tesla is upgrading airbag safety through a crazy software update
“This upgrade builds upon your vehicle’s superior crash protection by now using Tesla Vision to help offer some of the most cutting-edge airbag performance in the event of a frontal crash.”
Tesla is upgrading airbag safety through a crazy software update, which will utilize the company’s vision-first approach to enable better protection in the event of an accident.
Over the years, Tesla has gained an incredible reputation for prioritizing safety in its vehicles, with crash test ratings at the forefront of its engineers’ minds.
This has led to Tesla gaining numerous five-star safety ratings and awards related to safety. It is not just a statistical thing, either. In the real world, we’ve seen Teslas demonstrate some impressive examples of crash safety.
Everything from that glass roof not caving in when a tree falls on it to a Model Y surviving a drive off a cliff has been recorded.
However, Tesla is always looking to improve safety, and unlike most companies, it does not need a physical hardware update to do so. It can enhance features such as crash response and airbag performance through Over-the-Air software updates, which download automatically to the vehicle.
In Tesla’s 2025.32 Software Update, the company is rolling out a Frontal Airbag System Enhancement, which aims to use Tesla Vision, the company’s camera-based approach to self-driving, to keep occupants safe.
The release notes state (via NotaTeslaApp):
“This upgrade builds upon your vehicle’s superior crash protection by now using Tesla Vision to help offer some of the most cutting-edge airbag performance in the event of a frontal crash. Building on top of regulatory and industry crash testing, this release enables front airbags to begin to inflate and restrain occupants earlier, in a way that only Tesla’s integrated systems are capable of doing, making your car safer over time.”
The use of cameras to predict a better time to restrain occupants with seatbelts and inflate airbags prior to a collision is a fantastic way to prevent injuries and limit harm done to those in the vehicle.
The feature is currently limited to the Model Y.
