NASA’s Mars Lander finds that the Red Planet’s magnetic field is really weird
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 has made a change to its “American Heroes” discount, which takes $500 off the price of a vehicle purchase if you work in a certain field.
Tesla first launched the American Heroes discount earlier this year on May 22, 2025, and it initially started as a $1,000 deduction on the price of any of the company’s vehicles.
It formerly allowed military veterans, retirees, active-duty members, their spouses, first responders, teachers, and students. It utilized ID.me to verify their occupation.
However, Tesla has added a few groups of workers to this discount, according to language on its website:
“Tesla vehicles are perfect for everyday American heroes. Offer available to verified military veterans, retirees, active-duty members, their spouses, surviving spouses, first responders, medical providers, nurses, students and teachers verified through ID.me1. Adjustments applied when you place your order after verification. Eligibility criteria detailed at ID.me.”
The discount applies to all five Tesla vehicles, so it is not restricted to just the S3XY lineup.
The American Heroes discount is one of the several offers and incentives that Tesla offers on its vehicles. Currently, it is one of four offers Tesla has on its vehicles, with the others being:
- Full Self-Driving (Supervised) Trial: Three-month trial for those who use a referral code to buy a vehicle.
- Premium Connectivity Trial: One-month free
- Financing Offers: Tesla has various financing offers, including a 3.99% APR with $5,000 on Model S and Model X orders in the U.S.
These incentives help drive sales, but they also show Tesla’s appreciation for those who work in challenging fields. The discount has no expiration, as of now, but with this recent addition, Tesla likely has no plans to eliminate the program.
Tesla has occasionally launched discounts for military members near the 4th of July as well.

Tesla might be doing away with a long-included feature with its vehicles
It appears Tesla is mulling the possibility of not including key cards with its vehicles any longer.
Tesla might be doing away with a long-included feature with its vehicles, as it could be looking to phase out something that very few owners utilize.
Tesla Key Cards are included when you purchase your vehicle, and they assist in the initial setup process. However, after that, they are not super useful or relevant to the owner, as many rely on their Phone Key through the Tesla App to access their cars.
As such, it appears Tesla is mulling the possibility of not including key cards with its vehicles any longer. According to some language that has been removed from vehicle Owner’s Manuals that talks about the inclusion of key cards with the car upon delivery:
“Tesla provides you with two Model 3/Y key cards, designed to fit in your wallet.”
That sentence was removed from Owner’s Manuals, according to Not a Tesla App, which first spotted the change.

Interestingly, the timing of the phrase being removed from Owner’s Manuals comes just after Tesla launched its “affordable” Standard Models, and could be a small money-saving measure for the company.
Key Cards have been utilized by Tesla for its cars since 2017, as they became an included accessory with the vehicle. They still have their place and are useful for other applications, such as Valet service and even to be used by car owners if their phone is dead or if someone else needs to get into the car.
They can also be purchased in the Tesla Shop for $40.
It seems as if Tesla is planning to have owners be completely reliant on the Phone Key, which is more useful and convenient than carrying around the Key Cards.
Although it is minor, it is yet another strategy Tesla is using to trim any sort of costs that can be eliminated and could save money in the long run.

Elon Musk confirms Tesla FSD V14.2 will see widespread rollout
Musk shared the news in a post on social media platform X.
Elon Musk has confirmed that Tesla will be implementing a wide rollout of Full Self-Driving (FSD) V14 with the system’s V14.2 update. Musk shared the news in a post on social media platform X.
FSD V14.1.2 earns strong praise from testers
Musk’s comment came as a response to Tesla owner and longtime FSD tester AI DRIVR, who noted that it might be time to release Full Self-Driving to the fleet because V14.1.2 has already become very refined.
“95% of the indecisive lane changes and braking have been fixed in FSD 14.1.2. I haven’t touched my steering wheel in two days. I think it’s time, Tesla AI,” the longtime FSD tester wrote.
AI DRIVR’s comment received quite a bit of support from fellow Tesla drivers, some of whom noted that the improvements that were implemented in V14.1.2 are substantial. Others also agreed that it’s time for FSD to see a wide release.
In his reply to the FSD tester, CEO Elon Musk noted that FSD V14’s wide release would happen with V14.2. “14.2 for widespread use,” Musk wrote in his reply.
Mad Max mode makes headlines
One of the key features that was introduced with FSD’s current iteration is Mad Max mode, which allows for higher speeds and more frequent lane changes than the previous “Hurry” mode. Videos and social media posts from FSD testers have shown the system deftly handling complex traffic, merging seamlessly, and maintaining an assertive but safe driving behavior with Mad Max mode engaged.
Tesla AI head Ashok Elluswamy recently noted in a post on X that Mad Max mode was built to handle congested daytime traffic, making it extremely useful for drivers who tend to find themselves in heavy roads during their daily commutes. With Musk now hinting that FSD V14.2 will go on wide release, it might only be a matter of time before the larger Tesla fleet gets to experience the notable improvements of FSD’s V14 update.
