Researchers studying the red planet uncovered a big surprise: the Martian magnetic field is about 10 times stronger than previously thought, and constantly changing.

NASA’s InSight lander, a stationary robotic explorer tasked with studying the Martian interior, has spent just over a year on the red planet’s surface. In that brief time, it’s learned a lot of new information about our celestial neighbor. Namely, that its magnetic field is changing rapidly.

InSight is the first Mars robot to be outfitted with a magnetic sensor, which allows it to study Mars’ magnetic field up close and in detail.

“The ground-level data give us a much more sensitive picture of magnetization over smaller areas, and [pinpoints] where its coming from,” Catherine Johnson, lead author on the new study and a professor at the University of British Columbia said in a statement. “In addition to showing that the  magnetic field at the landing site was ten times stronger than the satellites anticipated, the data implied it was coming from nearby sources.”

InSight’s main objective is to help scientists understand how rocky planets grow and evolve by studying their interior. Before the lander touched down on the Martian surface, the planet’s magnetic field was measured by a fleet of satellites orbiting Mars. The satellites orbit at a distance, which could have skewed the data a bit.

Billions of years ago, Mars used to have a global magnetic field. That’s no longer the case, and scientists are trying to understand what happened. Without a global magnetic field, Mars’ atmosphere has slowly leaked out into space over billions of years.

There are localized magnetic fields, and thanks to InSight, we now know that they could have been attributed to ancient rocks buried beneath the planet’s surface. Johnson and her team are hopeful that InSight will be able to pinpoint which rocks are responsible and where exactly they’re located.

The new research, published this week in the journal Nature Geosciences, also suggests that the Martian magnetic fields are affected by the sun. No surprise there, as we learned with the Solar Orbiter and Parker Solar Probe missions, the sun affects everything in the solar system.

Charged particles emanate from the sun’s surface and whizz through the solar system, making up a celestial phenomenon called the solar wind. These particles carry a charge and as such can cause changes within the Martian magnetic fields when they come in contact with each other.

This was somewhat of a surprise as most of the previous observations have been from space looking down through the atmosphere.  Here on Earth, our planet’s global magnetic field protects much of the surface from the solar wind. But, since Mars doesn’t have a global magnetic field, solar particles are able to make their way through the planet’s atmosphere and to the surface.

“Because all of our previous observations of Mars have been from the top of its atmosphere or even higher altitudes, we didn’t know whether disturbances in solar wind would propagate to the surface,” said Johnson. “That’s an important thing to understand for future astronaut missions to Mars.”

InSight’s sensor recorded fluctuations in the magnetic field between day and night, including several short, mysterious pulsations around midnight. According to Johnson, this confirms that sensors on the planet’s surface can detect processes in the upper atmosphere.

So what causes these mysterious pulsations? The team believes that they form in multiple ways:  first from the solar wind and IMF enveloping the planet, and also from solar radiation charging the upper atmosphere and producing electrical currents, which in turn generate magnetic fields.

“We think these pulses are also related to the solar wind interaction with Mars, but we don’t yet know exactly what causes them,” said Johnson. “Whenever you get to make measurements for the first time, you find surprises and this is one of our ‘magnetic’ surprises.”

Tesla is hiring an Autopilot Test Engineer in Shanghai, a move that signals continued groundwork for the validation of Full Self-Driving (FSD) in China. The role is based in Lingang, the district that houses Gigafactory Shanghai and has become a key testing zone for advanced autonomous features.

As observed by Tesla watchers, local authorities in Shanghai’s Nanhui New City within Lingang have previously authorized a fleet of Teslas to run advanced driving tests on public roads. This marked one of the first instances where foreign automakers were permitted to test autonomous driving systems under real traffic conditions in China. 

Tesla’s hiring efforts come amid ongoing groundwork for a full FSD rollout in China. Earlier reporting noted that Tesla China has been actively preparing the regulatory and infrastructure foundation needed for full FSD deployment, even though the company has not yet announced a firm launch date for the feature in the market.

As per recent comments from Tesla China Vice President Grace Tao, the electric vehicle maker has been busy setting up the necessary facilities to support FSD’s full rollout in the country. In a comment to local media, Tao stated that FSD should demonstrate a level of performance that could surpass human drivers once it is fully rolled out.

“We have set up a local training center in China specifically to handle this adaptation,” Tao said. “Once officially released, it will demonstrate a level of performance that is no less than, and may even surpass, that of local drivers.”

Tesla CEO Elon Musk has been quite bullish about a potential FSD rollout in China. During the 2025 Annual Shareholder Meeting, Musk emphasized that FSD had only received “partial approval” in China, though full authorization could potentially arrive around February or March 2026. This timeline was reiterated by the CEO during his appearance at the World Economic Forum in Davos.

Tesla Model Y outsells all EV rivals in Europe in 2025 despite headwinds

The result highlights the Model Y’s continued strength in the region.

The Tesla Model Y was Europe’s most popular electric car in 2025, leading all EV models by a wide margin despite a year marked by production transition, intensifying competition, and anti-Elon Musk sentiments. 

The result highlights the Model Y’s continued strength in the region even as Volkswagen overtook Tesla as the top-selling EV brand overall.

As per data compiled by JATO Dynamics and reported by Swedish outlet Allt om Elbil, the Tesla Model Y recorded 149,805 registrations across Europe in 2025. That figure placed it comfortably at No. 1 among all electric car models in the region.

The Model Y’s performance in Europe is particularly notable given that registrations declined 28% year-over-year. The dip coincided with Tesla’s Q1 2025 transition to the updated Model Y, a changeover that temporarily affected output and deliveries in several markets. Anti-Elon Musk sentiments also spread across several European countries amidst the CEO’s work with U.S. President Donald Trump.

Even with these disruptions, the Model Y outsold its nearest rival by more than 50,000 units. Second place went to the newly launched Skoda Elroq with 93,870 registrations, followed by the Tesla Model 3 at 85,393 units. The Model 3 also recorded a 24% year-over-year decline. Renault’s new electric Renault 5 placed fourth with 85,101 registrations.

Other top performers included the Volkswagen ID.4, ID.3, and ID.7, along with the BMW iX1 and Kia EV3, many of which posted triple-digit growth from partial-year launches in 2024.

While the Model Y dominated individual model rankings, Volkswagen overtook Tesla as Europe’s top EV brand in 2025. Volkswagen delivered 274,278 electric cars in the region, a 56% increase compared to 2024. Much of that growth was driven by the Volkswagen ID.7. Tesla, by contrast, sold 236,357 electric vehicles in Europe, representing a 27% year-over-year decline.

JATO Dynamics noted that “Tesla’s small and aging model range faces fierce competition in Europe, both from traditional European automakers and a growing number of Chinese competitors.”

Despite intensifying competition and brand-level shifts, however. the Model Y’s commanding lead demonstrates that Tesla’s bestselling crossover remains a dominant force in Europe’s fast-evolving EV landscape.

SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.

Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.

The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.

Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:

“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”

Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.

Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.

This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.

Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:

“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”

Starlink recently crossed a massive milestone of over 10 million subscribers.
