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 CEO Elon Musk announces major update with texting and driving on FSD

“Depending on context of surrounding traffic, yes,” Musk said in regards to FSD v14.2.1 allowing texting and driving.

Tesla CEO Elon Musk has announced a major update with texting and driving capabilities on Full Self-Driving v14.2.1, the company’s latest version of the FSD suite.

Tesla Full Self-Driving, even in its most mature and capable versions, is still a Level 2 autonomous driving suite, meaning it requires attention from the vehicle operator.

You cannot sleep, and you should not take attention away from driving; ultimately, you are still solely responsible for what happens with the car.

The vehicles utilize a cabin-facing camera to enable attention monitoring, and if you take your eyes off the road for too long, you will be admonished and advised to pay attention. After five strikes, FSD and Autopilot will be disabled.

However, Musk announced at the Annual Shareholder Meeting in early November that the company would look at the statistics, but it aimed to allow people to text and drive “within the next month or two.”

He said:

“I am confident that, within the next month or two, we’re gonna look at the safety statistics, but we will allow you to text and drive.”

Today, Musk confirmed that the current version of Full Self-Driving, which is FSD v14.2.1, does allow for texting and driving “depending on context of surrounding traffic.”

There are some legitimate questions with this capability, especially as laws in all 50 U.S. states specifically prohibit texting and driving. It will be interesting to see the legality of it, because if a police officer sees you texting, they won’t know that you’re on Full Self-Driving, and you’ll likely be pulled over.

Some states prohibit drivers from even holding a phone when the car is in motion.

It is certainly a move toward unsupervised Full Self-Driving operation, but it is worth noting that Musk’s words state it will only allow the vehicle operator to do it depending on the context of surrounding traffic.

He did not outline any specific conditions that FSD would allow a driver to text and drive.

The Tesla Semi is moving closer to broader fleet adoption, with Keller Logistics Group wrapping up a key pre-production planning session with the electric vehicle maker’s team this week. 

The confidential meeting marks a major step for the mid-sized carrier in evaluating the electric truck for its regional routes.

Keller’s pre-production Tesla Semi sessions

Keller Logistics Group, a family-owned carrier with over 300 tractors and 1,000 trailers operating in the Midwest and Southeast, completed the session to assess the Tesla Semi’s fit for its operations. The company’s routes typically span 500-600 miles per day, positioning it as an ideal tester for the Semi’s day cab configuration in standard logistics scenarios. 

Details remain under mutual NDA, but the meeting reportedly focused on matching the truck to yard, shuttle and regional applications while scrutinizing economics like infrastructure, maintenance and incentives.

What Keller’s executives are saying

CEO Bryan Keller described the approach as methodical. “For us, staying ahead isn’t a headline, it’s a habit. From electrification and yard automation to digital visibility and warehouse technology, our teams are continually pressure-testing what’s next. The Tesla Semi discussion is one more way we evaluate new tools against our standards for safety, uptime, and customer ROI. We don’t chase trends, we pressure-test what works,” Keller said.

Benjamin Pierce, Chief Strategy Officer, echoed these sentiments. “Electrification and next-generation powertrains are part of a much broader transformation. Whether it’s proprietary yard systems like YardLink™, solar and renewable logistics solutions, or real-time vehicle intelligence, Keller’s approach stays the same, test it, prove it, and deploy it only when it strengthens service and total cost for our customers,” Pierce said.
