Martian auroras offer clues to how the red planet lost its water
Aurorae are a dazzling light spectacle often visible at high-latitude locations here on Earth. They’re colorful and mesmerizing, but most of all, they’re mysterious.
A new study has found that this same phenomenon also happens on Mars. In research presented last week at the American Geophysical Union’s annual Fall meeting, scientists revealed that the most common form of Martian aurorae is called the proton aurora.
Just like the auroras we see here on Earth, proton aurorae are formed when the solar wind—a stream of charged particles emanating from the Sun—interacts with the atmosphere. That interaction often manifests itself as a mesmerizing swirl of colored lights in the night sky.
On Mars, however, the auroras appear during the daytime and onlookers would need special ultraviolet glasses to see them. That’s because they’re invisible to the naked eye, but can be spotted with special UV instruments.
These auroras aren’t just a future Martian tourist attraction, they have a scientific value. We could better understand how Mars is losing water to space and more about how the planet’s climate is changing.
Proton auroras were first discovered in 2016 by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft. MAVEN is investigating how the Red Planet lost its atmosphere and water, ultimately transforming its climate from one that may have supported life to one that is inhospitable.
The observed aurora can help researchers track the amount of water lost since the auroras are related to water loss.
“In this new study using MAVEN/IUVS data from multiple Mars years, the team has found that periods of increased atmospheric escape correspond with increases in proton aurora occurrence and intensity,” Andréa Hughes of Embry-Riddle Aeronautical University in Daytona Beach, Florida said in a news release.
Auroras on both planets start with the same source: the solar wind. On Earth, they appear when the solar wind slams into our planet’s magnetic field. High-energy collisions occur as the charged solar particles interact with particles of atmospheric gas. Each type of particle produces a different colored light in the sky.
Martian auroras start in much the same way, charged particles from the solar wind collide with a cloud of hydrogen that surrounds the red planet. When this happens, protons in the solar wind become neutral after stealing electrons from the hydrogen atoms. They then collide with other molecules in the Martian atmosphere, producing an ultraviolet glow.
Since the hydrogen cloud surrounding the planet is created in part by water being lost to space, this could give scientists a way to measure the amount of water lost over time.
When the MAVEN team first observed the proton aurora, they thought they were witnessing an unusual phenomenon. “At first, we believed that these events were rather rare because we weren’t looking at the right times and places,” Mike Chaffin, a research scientist at the University of Colorado Boulder’s Laboratory for Atmospheric and Space Physics (LASP) said in a statement.
After Chaffin’s team took a closer look, they discovered that the proton auroras occur quite frequently, especially in the summer. This is probably due to seasonal variation in the hydrogen cloud that surrounds Mars. The team noted that during the Martian summer, the cloud lines up just right to produce near-constant auroras.
But that’s not all. The researchers also discovered that as temperatures climb during the summer, rising dust clouds would carry water vapor away from the planet’s surface. That water vapor is then broken down into its components: hydrogen and oxygen. As more hydrogen escapes into space, it enhances the hydrogen cloud enveloping Mars and ultimately leads to more frequent (and brighter) proton auroras.
“Observations of proton auroras at Mars provides a unique perspective of hydrogen and, therefore, water loss from the planet,” physicist Edwin Mierkiewicz of Embry-Riddle Aeronautical University in Florida said in a statement.
“Through this research, we can gain a deeper understanding of the Sun’s interactions with the upper atmosphere of Mars and with similar bodies in our Solar System, or in another solar system, that lacks a global magnetic field.”
So, if we ever do make it to Mars, those first visitors are going to witness some truly out-of-this-world sights—as long as they packed their ultraviolet goggles.
Tesla is launching its solution to end Supercharger fights once and for all, eliminating any confusion on who is to charge next at a congested location.
Last year, a notable incident at a Tesla Supercharger led to a fight, and it all stemmed from a disagreement over who arrived at the location first.
Congestion at Tesla Superchargers is a pretty infrequent occurrence for most of us, but there are more congested and popular areas where wait times can be extensive. An unfortunate growing pain of EV ownership is the plain fact that chargers are not as available as gas pumps, and there are, at times, lines to charge.
This can cause tensions to flare and people to get entitled when visiting Superchargers. Nobody wants to spend hours at a Supercharger, but now, there will be no more confusion when there is a queue, and that’s thanks to Tesla’s new Virtual Queue for Superchargers.
Tesla is finally starting to build out the Virtual Supercharger Queue, according to Not a Tesla App, but it still relies on drivers to make it work.
When a driver is near a Supercharger that is full, a message will pop up on the Tesla App, using the driver’s location to determine their eligibility to join the virtual queue.
The app states:
“While the app is closed, Tesla uses your location to notify you of accurate wait times at Superchargers when you arrive.”
Another message within the app states:
“There is a waitlist to charge. Are you sure you want to start a charging session now?”
This sounds as if it will require drivers to act appropriately and only plug in when the app prompts them to do so, by letting them know it is their turn.
The app will notify the driver of their position in the queue, as well as how many vehicles are ahead of them.
Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means
The company announced a while back that it would be working on a solution for this issue. Personally, I’ve only had to wait at a Supercharger for a charge on one occasion, and there was a line of between 3 and 10 cars during this singular occurrence.
I’m out at the Lancaster, PA Supercharger and showed up with a queue of three vehicles.
It’s now up to five and there have been several issues with order of arrival and confusion about who is first.
Any update on Supercharger queue? @elonmusk @aelluswamy @r_jegaa

There were no conflicts or arguments about who had arrived first, but there was some discussion between several drivers during my time there about who was to charge first. Throw a non-Tesla EV into the mix, one that can only charge at a pull-in spot, and that causes even more of a complication.

Tesla offers awesome Free Supercharging incentive on an unexpected vehicle
In the past, Tesla has used Free Supercharging to incentivize the purchase of its expensive vehicles, like the Model S and Model X. However, those vehicles are leaving the company lineup, and Tesla saw a benefit from applying the incentive to another car.
Tesla is offering an awesome new Free Supercharging incentive on a vehicle that is sort of unexpected.
In the past, Tesla has used Free Supercharging to incentivize the purchase of its expensive vehicles, like the Model S and Model X. However, those vehicles are leaving the company lineup, and Tesla saw a benefit from applying the incentive to another car.
Tesla North America has introduced a compelling new incentive aimed at boosting Model 3 sales. Starting with orders placed on or after April 24, buyers of the Model 3 Premium (Long Range) and Performance variants in the United States will receive one full year of complimentary Supercharging.
The offer applies exclusively to new vehicle orders and does not extend to existing owners or other trims like the base Rear-Wheel Drive model.
New orders of Model 3 Premium & Performance now come with 1 year of free Supercharging 🇺🇸
Also, all Teslas pay the lowest Supercharging rates – all others pay a ~40% premium or need a subscription

The announcement underscores Tesla’s continued dominance in EV charging infrastructure.
While the incentive provides 12 months of zero-cost access to the Supercharger network, Tesla also reiterated its pricing structure: all Tesla vehicles receive the lowest Supercharging rates.
Non-Tesla EVs, by contrast, pay approximately 40 percent more per kWh or must purchase a subscription to access the network at standard rates. This tiered approach highlights the strategic value of owning a Tesla, where seamless integration with the world’s largest and most reliable fast-charging network remains a key differentiator.
For prospective buyers, the savings can be substantial. Depending on driving habits, a typical Model 3 owner might log 12,000–15,000 miles annually.
With average Supercharging costs around $0.40–$0.50 per kWh, one year of free sessions could translate to $800–$1,200 in avoided expenses.
That effectively lowers the total cost of ownership and makes long-distance travel more affordable from day one. Early delivery customers have already noted similar past incentives, with one Cybertruck owner reporting over $2,400 saved in just six months under similar offers that Tesla has deployed in the past.
The timing of the offer appears strategic. Tesla faces growing competition from other automakers expanding their own charging networks and offering aggressive EV incentives.
By bundling free Supercharging rather than discounting the vehicle’s MSRP, Tesla preserves perceived value while directly addressing one of the biggest barriers for new EV adopters: charging costs and convenience.
The move also encourages higher-mileage use of the network, generating valuable real-world data for Tesla’s autonomous driving development.
Why Tesla would apply this incentive to the Model 3 is pretty interesting. It usually is a pretty good incentive to move units out the door, so there’s some speculation whether Tesla is planning to launch new upgrades to the mass-market sedan in the coming months, and the company wants to move what will be outdated units from its inventory.
However, there is also just the idea that Tesla could be attempting to stimulate some early quarter demand for the Model 3, especially as the Model Y continues to sell very well. Tesla’s loss of the $7,500 EV tax credit last year had an impact on sales, and Tesla might be testing some formidable options to see if it can add some demand once again.

Tesla Cybercab gets crazy change as mass production begins
Tesla has officially kicked off mass production of its groundbreaking Cybercab robotaxi at Giga Texas, and the first units rolling off the line feature a striking transformation that’s turning heads across the EV community.
Tesla Cybercab has evidently received a pretty crazy change from an aesthetic standpoint, as the company has made the decision to offer an additional finish on the vehicle as mass production is starting.
Tesla has officially kicked off mass production of its groundbreaking Cybercab robotaxi at Giga Texas, and the first units rolling off the line feature a striking transformation that’s turning heads across the EV community.
VIN Zero—the very first production Cybercab—showcases a vibrant champagne gold exterior with a high-gloss finish, a dramatic departure from the flat, matte-wrapped prototypes that debuted at the 2024 “We, Robot” event.

This glossy sheen is a pretty big pivot from what was initially shown by Tesla. The company has maintained a pretty flat tone in terms of anything related to custom colors or finishes.
A specialized clear coat or process delivers the deep, reflective gloss without conventional painting. The result is a premium, mirror-like shine, and it looks pretty good, and gives the compact two-seater a more luxurious and futuristic presence than the subdued matte prototypes.
Photos shared by Tesla community members reveal VIN Zero in a showroom-like setting at Giga Texas, highlighting refined panel gaps, large aero wheel covers, and the signature no-steering-wheel, no-pedals interior optimized for full autonomy.
The open frunk in some images offers a glimpse of practical storage, while the overall build quality appears more polished than that of test mules.
This glossy evolution aligns with Tesla’s broader production ramp. After the first unit in February 2026, the company has shifted to volume manufacturing, with dozens of units already spotted in outbound lots. CEO Elon Musk and the team aim for hundreds per week, paving the way for unsupervised FSD robotaxi networks that could slash ride costs to pennies per mile.
The Cybercab holds Tesla’s grand ambitions of operating a full-service ride-hailing service without any drivers in its grasp. Tesla has yet to solve autonomy, but is well on its way, and although its timelines are usually a bit off, improvements often come through the Over-the-Air updates to the Full Self-Driving suite.
