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.”

A Washington, D.C., man has been charged with vandalizing Tesla vehicles across Northeast D.C., with authorities labeling the acts as domestic terrorism. Tesla vandalism attacks increased in the first quarter.

Justin Fisher, 49, faces four misdemeanor counts of defacing public or private property for incidents between March 1 and March 21, 2025, U.S. Attorney Edward R. Martin Jr. and Metropolitan Police Department Chief Pamela Smith announced.

Court documents outline Fisher’s alleged offenses, which targeted Tesla vehicles owned by multiple victims. The first case of Tesla vandalism occurred on March 1 at 10:11 a.m. in the 200 block of K Street, followed by a second on March 2 at 6:15 p.m. in the 200 block of 11th Street. The third time Fisher reportedly vandalized a Tesla was on March 8 at 8:05 a.m. in the 600-700 blocks of F Street. The last time the suspect vandalized a Tesla was on March 21 at 5:15 p.m. in the 600 block of G Street. Fisher was arrested on April 1, 2025, by the Metropolitan Police Department, which continues to investigate the cases.

“The so-called ‘Tesla Takedown’ is domestic terrorism, and my team is taking it on front and center,” said U.S. Attorney Martin. “These attacks are not just an attack on someone’s property. They are meant to intimidate and suppress political speech and shut down the marketplace of ideas,” Martin said. The U.S. Attorney’s Office for the District of Columbia is prosecuting the case.

“If you target Tesla and break the law, then you can expect consequences,” said Attorney General Pamela Bondi. “This Department of Justice will not tolerate such criminal acts.”

Fisher appeared in Superior Court and was released on personal recognizance. His initial status hearing is set for June 10, 2025. The misdemeanor charges carry significant weight due to their domestic terrorism designation, signaling a broader crackdown on ideologically driven property crimes. The attacks highlight tensions surrounding Tesla, which has faced scrutiny and admiration alike from the public.

The case underscores the challenges of balancing free expression with criminal accountability. As the investigation unfolds, authorities aim to clarify Fisher’s motives.

Tesla Robotaxi benefits from Trump’s new self-driving rules

Trump admin eases self-driving rules. Tesla could launch FSD faster. Austin Robotaxi launch now looks even stronger.

The Tesla Robotaxi network will benefit from U.S. President Trump’s new self-driving rules.

The Trump administration is loosening regulations to support U.S. automakers like Tesla in developing self-driving cars. The United States government aims to outpace Chinese competitors in autonomous vehicle development. The policy shift, which was announced by U.S. Transportation Secretary Sean Duffy on Thursday, targets federal safety rules and crash reporting requirements to accelerate autonomous vehicle innovation.

The Transportation Department outlined exemptions allowing U.S. companies to bypass specific safety regulations for self-driving vehicles used in research, demonstrations, and non-commercial settings. Previously, such exemptions were applied mainly to foreign vehicles with standards different from those in the United States. The department also plans to streamline crash reporting rules, which Elon Musk has criticized, and move toward a unified national standard, replacing fragmented state regulations.

“We’re in a race with China to out-innovate, and the stakes couldn’t be higher,” said Transportation Secretary Sean Duffy in a statement. “Our new framework will slash red tape and move us closer to a single national standard.”

The regulatory changes align with Tesla’s ambitions in autonomous driving, particularly related to its Robotaxi network. On Wednesday, Musk confirmed during a Tesla investor call that the company is prepared to launch self-driving Tesla robotaxis in Austin, Texas, by June. Tesla’s Full Self-Driving (FSD) technology, a cornerstone of its robotaxi plans, could benefit from the eased rules, expediting testing and deployment.

The exemptions are designed to level the playing field for U.S. automakers, giving Tesla and others more flexibility to innovate. The administration aims to foster a competitive environment against Chinese firms advancing in autonomous vehicle technology by simplifying crash reporting and harmonizing regulations. Industry observers note China’s aggressive push for self-driving tech has pressured U.S. policymakers to act.

Tesla’s Austin Robotaxi rollout will be a key testbed for its FSD software under the new regulatory framework. The company has been refining FSD, with recent updates showcasing improved performance. The Transportation Department’s move could accelerate Tesla’s timeline for scaling its autonomous fleet, a critical step toward Musk’s vision of the Robotaxi network.

The policy shift underscores a broader U.S. strategy to maintain technological leadership. With Tesla at the forefront, the loosened rules could reshape the self-driving landscape, positioning American automakers to challenge global rivals.

Kia EV6, EV9 and Niro Owners Gain Access to Over 21,500 Tesla Superchargers

Kia has announced that owners of the EV6, EV9, and Niro EVs have officially gained access to over 21,500 Tesla Supercharger locations in North America.

However, its announcement also contained an apology to Tesla.

First, Kia said that its three EV offerings will have access to Tesla’s expansive Supercharger Network. More than 40,000 DC fast chargers are available to Kia EV drivers, a major uptick as Tesla Supercharger access nearly doubles the number of accessible piles.

Sean Yoon, President of Kia North America and Kia America, said:

“Kia is committed to an exceptional ownership experience, and expanding the network of available DC fast chargers to our EV customers is an important component to maintaining the brand’s leadership in electrified mobility. Now, with access to the Tesla Supercharger network of DC fast chargers, our EV owners can feel even more confident in their decision to purchase or lease a fully electric Kia vehicle.”

Kia owners who have a CCS1 Charging Port will have access to an NACS adapter through dealerships. This will enable compatibility, as current inlets are not NACS, the port that Tesla utilizes.

However, Kia will eliminate the need for this adapter starting with the 2025 EV6 and 2026 EV9. These will come standard with NACS inlets.

We mentioned Kia included somewhat of an apology to Tesla, which is related to social media posts from “certain Nordic distributors,” as the company puts it:

Kia said in its announcement:

Kia America is aware of marketing posts by certain Nordic distributors. These initiatives were developed entirely independently by those distributors, without direction from Kia AmericaKia Europe or Kia Global. We want it to be clear that these posts do not reflect the position of Kia America, and we remain committed to clear and professional communication that reflects our values.”

The company also said that it “condemns the recent attacks that disrupt the availability of convenient and affordable charging for our customers.”
