Martian dust storms are driving away spacecraft-saving dust devils
Dust devils are pretty common on Mars – the Red Planet is, after all, a very dusty and windy place. What’s a bit more rare is capturing one of the whirling devils on film. That’s because they fade away nearly as quickly as they appear.
But in October 2019, NASA’s Mars Reconnaissance Orbiter managed to snap a photo of a massive dust devil in action, courtesy of the Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment (HiRISE), a powerful camera that’s been snapping photos of the Martian surface since 2006.
NASA’s first glimpse of one of these dust storms came in 1971 when the Mariner 9 spacecraft — the first to orbit another planet — arrived at the red planet. Since then, we’ve seen quite a few of these dusty spectacles global storms: in 1977 (twice), 1982, 1994, 2001, 2007 and 2018.
In 2018, we lost the Opportunity rover to the strongest dust storm ever observed on Mars. It blotted out nearly all of the sun’s light for several weeks, turning day into night and preventing the rover from being able to charge its batteries. (Opportunity and its twin, Spirit, ran on solar power, as opposed to Curiosity and the Mars 2020 rover, which run on nuclear power.)
Martian dust storms are common, especially at specific times in the year, like during the southern hemisphere’s spring and summer. Localized storms tend to last a couple of days and can cover regions of the planet the size of the United States. But planet-encircling ones are a different story.
These massive, global storms are usually unpredictable, and can linger for months at a time. “We still don’t know what drives the variability, but the 2018 storm gives another data point,” says Scott Guzewich, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who’s a lead in NASA’s dust storm investigation.
Dust devils are rotating columns of air and dust that form when hot air from the surface rises. The current of air created forms a whirlwind, which can be useful for clearing off solar panels on spacecraft as they pass over.
As we move towards potential human missions we need to know how the dust will affect astronauts as well as their equipment. Understanding how often these phenomena occur will be extremely helpful for future missions.
During the dust storm of 2018, Curiosity was able to collect data about the storm, watching as its effects were felt half a world away from where Opportunity sat, hunkered down and hibernating.
Curiosity discovered that dust devils disappear during a dust storm, which happens to be when we need them the most. And they’re gone for several months afterwards as well. This is because the storm interrupts the wind-generating processes that spawn the dust devils.
According to Guzewich, understanding a global storm’s impact on dust devils is a crucial component in planning how to manage equipment during future Mars missions. “You need to be prepared to go a while before your next dust devil passes over and cleans you off,” he said.
Researchers at the University of Arizona recently published details on a newly photographed dust devil, which formed on the volcanic plains of Amazonis Planitia.
According to the HiRISE imaging team, the core of the dust devil is 164 feet (50 meters) wide, and probably about 2,32 feet (650 meters) tall. As massive as it sounds, there are even larger ones whirling around.
In March 2012, HiRISE took a photo of an active dust devil that was a whopping 12 miles (20 kilometers) tall. But was only slightly wider than the most recent one, at just over 229 feet (70 meters) wide.
For the first time, humanity has a fleet of spacecraft orbiting Mars as well as one rover roaming the surface right now (with two more to follow in the coming months). With their help, scientists will be able to better understand this puzzling phenomenon.
Chevy answered Tesla’s new Standard Model 3 and Model Y offerings with its second-generation Bolt EV, a car that actually appeals to those who were looking for affordability.
Earlier this week, Tesla unveiled the Model 3 and Model Y Standard, two stripped-down versions of the cars of the same name it already offers. The Long Range versions are now labeled as “Premium,” while the Performance configurations stand alone.

However, many people were sort of upset with what Tesla came to market with. For well over a year, it has been transparent that it was planning to develop affordable models, and this year, it was forced to take action to counter the loss of the $7,500 EV tax credit.
The Model 3 Standard starts at $36,990, while the Model Y Standard comes in at $39,990. While these are cheaper than the company’s Premium offerings, many fans said that Tesla missed the mark with the pricing, as these numbers are not necessarily “affordable.”
At the very least, they will likely miss the mark in helping Tesla regain annual growth rates for its deliveries. Tesla will likely rely on its “unboxed process,” which will be used to manufacture the Cybercab and potentially other affordable models in the future. These will be priced at below $30,000.
Other carmakers are making their moves and were able to undercut Tesla’s new Standard offerings, Chevrolet being one of them.
This week, the company launched its second-gen Bolt EV, which starts at just $28,995.
Here are the full specs:
- 65 kWh LFP battery
- 255 miles of range (EPA estimated)
- Native NACS port for Tesla Supercharger accessibility without an adapter
- Up to 150 kW charging speed
- Bidirectional power of 9.6 kW
- Front-Wheel-Drive
- 10-80% charging in just 26 minutes
- No Apple CarPlay or Android Auto
- SuperCruise capable
- 11.3″ touchscreen, 11″ digital gauge cluster
- 16 cubic feet of cargo capacity
- Other Trims
- RS – $32,000
- Base LT – $28,995
- Deliveries begin in early 2026
Let’s be frank: Tesla fans are unlikely to bat an eye at other OEM offerings. However, first-time EV buyers might be looking for something more price accessible, so vehicles under $30,000 are where they will look first, at least for most people.
If money isn’t an option, people will consider spending a minimum of $37,000 on a new vehicle, especially an EV, as a first-time owner.
The Bolt EV could be something that does well, especially considering its one of only a handful of EVs that are priced at around $30,000 brand new in the U.S.
The others are:
- Nissan Leaf S ($28,140)
- Mini Cooper SE ($30,900)
- Fiat 500e ($32,500)
While these cars are priced at around $30,000 and are affordable, they each offer minimal range ratings. The Nissan Leaf S and Fiat 500e have just 149 miles, while the Mini Cooper SE has 114 miles.
Tesla’s flagship sedan, the Model S, has officially been named one of TIME Magazine’s Best Inventions of the 2000s. It joins its sibling, the Model 3, which made the list in 2017.
The Model S is among the most crucial developments in the automotive industry in the last century.
Just as the Ford Model T made its mark on passenger transportation, becoming the first combustion engine vehicle to be successfully developed and marketed at a time when horse and buggy were the preferred mode of transportation, the Model S revolutionized things a step further.
Although it was not the first EV to be developed, the Tesla Model S was the EV that put EVs on the map. In 2012, TIME recognized the Model S as a piece of technology that could truly transform the car industry.
The publication wrote:
“This electric four-door sedan has the lines of a Jaguar, the ability to zip for 265 miles (426 km) on one charge—that’s the equivalent of 89 m.p.g. (2.6 L/100 km)—and touchscreen controls for everything from GPS navigation to adjusting the suspension.”
Looking back, TIME was right on. The Tesla Model S was truly a marvel for its time, and it, along with the OG 2008 Roadster, can be seen as the first two EVs to push electrification to the mainstream.
As TIME described this year, the Model S “proved to be a game-changing experience for electric vehicles,” and it ended up truly catalyzing things for not only the industry, but Tesla as well.
The Model S acted as a fundraiser of sorts for future vehicles, just as the Model X did. They paved the way for the Model 3 and Model Y to be developed and offered by Tesla at a price point that was more acceptable and accessible to the masses.
The Current State of the Tesla Model S
The Model S contributes to a very small percentage of Tesla sales. The company groups the Model S with the Model X and Cybertruck in its quarterly releases.
Last year, that grouping sold 85,133 total units, a small percentage of the 1.789 million cars it delivered to customers in 2024.
Things looked to be changing for the Model S and the Model X this year, as Tesla teased some improvements to the two cars with a refresh. However, it was very underwhelming and only included very minor changes.

It appeared as if Tesla was planning to sunset the two cars, and while it has not taken that stance yet, it seems more likely that the company will begin taking any potential options to heart.
CEO Elon Musk said a few years ago that the two cars were only produced due to “sentimental reasons.”
Tesla (NASDAQ: TSLA) has had a few weeks of overwhelmingly bullish events, and it is inciting several analysts to change their price targets as they expect the stock to potentially go Plaid Mode in the near future.
Over the past week, Tesla has not only posted record deliveries for a single quarter, but it has also rolled out its most robust Full Self-Driving (Supervised) update in a year. The new version is more capable than ever before.

However, these are not the only things moving the company’s overall consensus on Wall Street toward a more bullish tone. There are, in fact, several things that Tesla has in the works that are inciting stronger expectations from analysts in New York.
TD Cowen
TD Cowen increased its price target for Tesla shares from $374 to $509 and gave the stock a ‘Buy’ rating, based on several factors.
Initially, Tesla’s positive deliveries report for Q3 set a bullish tone, which TD Cowen objectively evaluated and recognized as a strong sign. Additionally, the company’s firm stance on ensuring CEO Elon Musk is paid is a positive, as it keeps him with Tesla for more time.

Musk, who achieved each of the tranches on his last pay package, could obtain the elusive title as the world’s first-ever trillionaire, granted he helps Tesla grow considerably over the next decade.
Stifel
Stifel also increased its price target on Tesla from $440 to $483, citing the improvements Tesla made with its Full Self-Driving suite.
The rollout of FSD v14.1 has been a major step forward for the company. Although it’s in its early stages, Musk has said there will be improved versions coming within the next two weeks.
Stifel raises Tesla price target by 9.8% over FSD, Robotaxi advancements
Analysts at the firm also believe the company has a chance to push an Unsupervised version of FSD by the end of the year, but this seems like it’s out of the question currently.
It broke down the company’s FSD suite as worth $213 per share, while Robotaxi and Optimus had a $140 per share and $29 per share analysis, respectively.
Stifel sees Tesla as a major player not only in the self-driving industry but also in AI as a whole, which is something Musk has truly pushed for this year.
UBS
While many firms believe the company is on its way to doing great things and that stock prices will rise from their current level of roughly $430, other firms see it differently.
UBS said it still holds its ‘Sell’ rating on Tesla shares, but it did increase its price target from $215 to $247.
It said this week in a note to investors that it adjusted higher because of the positive deliveries and its potential value with AI and autonomy. However, it also remains cautious on the stock, especially considering the risks in Q4, as nobody truly knows how deliveries will stack up.
In the last month, Tesla shares are up 24 percent.
