Mars’ stunning polar ice caps spotted in new image captures from orbiter

Mars: beautiful, desolate, and the planet in the solar system whose seasons most closely match ours.

The European Space Agency (ESA) recently released an image of the red planet’s north polar region and its stunning ice caps. The image coincided with the Seventh International Conference on Mars Polar Science and Exploration which took place last week (Jan. 13 to 17) in Argentina.

The image, taken by the Mars Express orbiter, highlights some of the natural processes that shape the planet’s surface.

Mars may seem like a dry, desert-like world devoid of water, but its supply is locked up at the poles. Thick layers of water ice cover the Martian polar regions all-year long, with an added layer of frozen carbon dioxide forming in the frigid winter months.

In the image, the Martian terrain peeks through the ice, appearing as zebra stripes. This view highlights the stark contrast between the ice and ruddy Martian terrain.

The stripes are part of larger spiral patterns that emanate outward from the center of the north pole. But what causes them?

Scientists think that this unique pattern is formed by katabatic winds, that carry higher-density air to lower elevations. On Mars, these winds ferry cold, dense air from the regions’ glaciers down to lower elevations containing valleys and depressions.

At the same time, Mars is rotating (just like the Earth) creating another cool phenomenon called the coriolis effect, which manifests as the spiral pattern we see in the image. (On Earth, the Coriolis force is seen in weather events such as hurricanes.)

Scientists are very interested in the ice deposits covering Mars’s polar regions. Not only do they contain evidence that can tell us how the red planet’s climate has changed over millions of years, but it’s also a source of water for future human missions.

The Mars Express orbiter was designed to study the red planet’s surface processes over time, documenting seasonal changes at the poles as well as track winds and any storms that pop up.

To date the orbiter has lived up to the task, expanding our understanding of just how wet ancient Mars was. It also sheds light on activities below the planet’s surface.

Understanding what sort of processes are happening at the poles will help inform future human missions to the red planet, especially in regards to the search for water.

Water is a precious commodity and if there are other places thanks to some recent data, NASA is hoping that future missions can land a bit further south, near a region called Arcadia Planitia, and rely on its water resources instead of having to travel to the poles and hauling water back.

Tesla Full Self-Driving gets sparkling review from South Korean politician

“Having already ridden in an unmanned robotaxi, the novelty wasn’t as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about.”

Tesla Full Self-Driving got its first sparkling review from South Korean politician Lee So-young, a member of the country’s National Assembly, earlier this week.

Lee is a member of the Strategy and Finance Committee in South Korea and is a proponent of sustainable technologies and their applications in both residential and commercial settings. For the first time, Lee was able to utilize Tesla’s Full Self-Driving technology as it launched in the country in late November.

Her thoughts on the suite were complimentary to the suite, stating that “it drives just as well as most people do,” and that “it already feels like a completed technology.”

Her translated post says:

“Finally, today I got to experience Tesla FSD in Seoul. Thanks to the Model S sponsored by JiDal Papa^^, I’m truly grateful to Papa. The route was from the National Assembly -> Mangwon Market -> Hongik University -> back to the National Assembly. Having already ridden in an unmanned robotaxi, the novelty wasn’t as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about. Once it actually spreads into widespread use, I feel like our daily lives are going to change a lot. Even I, with my license gathering dust in a drawer, don’t see much reason to learn to drive a manual anymore.”

Tesla Full Self-Driving officially landed in South Korea in late November, with the initial launch being one of Tesla’s most recent, v14.1.4.

It marked the seventh country in which Tesla was able to enable the driver assistance suite, following the United States, Puerto Rico, Canada, China, Mexico, Australia, and New Zealand.

It is important to see politicians and figures in power try new technologies, especially ones that are widely popular in other regions of the world and could potentially revolutionize how people travel globally.

Tesla dispels reports of ‘sales suspension’ in California

“This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.

Sales in California will continue uninterrupted.”

Tesla has dispelled reports that it is facing a thirty-day sales suspension in California after the state’s Department of Motor Vehicles (DMV) issued a penalty to the company after a judge ruled it “misled consumers about its driver-assistance technology.”

On Tuesday, Bloomberg reported that the California DMV was planning to adopt the penalty but decided to put it on ice for ninety days, giving Tesla an opportunity to “come into compliance.”

Tesla enters interesting situation with Full Self-Driving in California

Tesla responded to the report on Tuesday evening, after it came out, stating that this was a “consumer protection” order that was brought up over its use of the term “Autopilot.”

The company said “not one single customer came forward to say there’s a problem,” yet a judge and the DMV determined it was, so they want to apply the penalty if Tesla doesn’t oblige.

However, Tesla said that its sales operations in California “will continue uninterrupted.”

It confirmed this in an X post on Tuesday night:

The report and the decision by the DMV and Judge involved sparked outrage from the Tesla community, who stated that it should do its best to get out of California.

One X post said California “didn’t deserve” what Tesla had done for it in terms of employment, engineering, and innovation.

Tesla has used Autopilot and Full Self-Driving for years, but it did add the term “(Supervised)” to the end of the FSD suite earlier this year, potentially aiming to protect itself from instances like this one.

This is the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” naming. Previous Transportation Secretary Pete Buttigieg was vocally critical of the use of the name “Full Self-Driving,” as well as “Autopilot.”

New EV tax credit rule could impact many EV buyers

We confirmed with a Tesla Sales Advisor that any current orders that have the $7,500 tax credit applied to them must be completed by December 31, meaning delivery must take place by that date. However, it is unclear at this point whether someone could still claim the credit when filing their tax returns for 2025 as long as the order reflects an order date before September 30.

Tesla owners could be impacted by a new EV tax credit rule, which seems to be a new hoop to jump through for those who benefited from the “extension,” which allowed orderers to take delivery after the loss of the $7,500 discount.

After the Trump Administration initiated the phase-out of the $7,500 EV tax credit, many were happy to see the rules had been changed slightly, as deliveries could occur after the September 30 cutoff as long as orders were placed before the end of that month.

However, there appears to be a new threshold that EV buyers will have to go through, and it will impact their ability to get the credit, at least at the Point of Sale, for now.

Delivery must be completed by the end of the year, and buyers must take possession of the car by December 31, 2025, or they will lose the tax credit. The U.S. government will be closing the tax credit portal, which allows people to claim the credit at the Point of Sale.

If not, the order can still go through, but the buyer will not be able to claim the tax credit, meaning they will pay full price for the vehicle.

This puts some buyers in a strange limbo, especially if they placed an order for the Model Y Performance. Some deliveries have already taken place, and some are scheduled before the end of the month, but many others are not expecting deliveries until January.
