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 has been testing its all-electric, two-seater Cybercab on public roads for months now.
Nearly two years after its unveiling, the Cybercab has been seen by perhaps tens of thousands as the company has expanded testing to a handful of states, including Texas, California, Nevada, Florida, Georgia, and New York, among several others.
However, nobody has seen one like this quite yet.
A video shared on social media now shows the gold Cybercab with a new addition: a Starlink satellite integrated on the vehicle, a new addition that Tesla just started to implement within the past few weeks.
@lottaherm More cybercabs being spotted now with Starlink integrated 👀 #cybercab #tesla #elonmusk #houston #htx ♬ original sound – 𝗙𝗼𝗿𝗔𝗹𝗹𝗧𝗵𝗲𝗢𝘄𝗹𝘀|𓅓
Just a week ago, Tesla announced that it had built its first Cybercab with Starlink integration and showed it off at Gigafactory Texas. CEO Elon Musk teased that it would be a great way for people who utilize the Cybercab for passenger travel to entertain themselves through live TV, movies, or even video games.
Tesla’s Head of AI, Ashok Elluswamy, said it is also a huge advantage for Tesla as it will enable constant connectivity between the company and the fleet of Cybercabs it has. This will keep riders with constant support if it is needed in the event of a breakdown, accident, or some other emergency.
Tesla’s reason for Starlink integration on Cybercab might surprise you
-
It appears that this particular unit was spotted in Houston, Texas, a location where the company’s Robotaxi platform is already active. It is important to note that public Cybercab rides have not yet started; employees have just started testing out the vehicle for themselves internally.
Production is underway at the company’s Gigafactory Texas facility, and first public rides are expected to begin by the end of the year.
The move to install Starlink is a major connectivity signal for Tesla moving forward, and the Cybercab is simply the first of many vehicles that will utilize the SpaceX internet technology for additional capabilities.
Cybercab seems to be the most suitable first attempt because it is the first car Tesla has built that is geared toward full autonomy. As Tesla solves it completely, Starlink integration throughout the company’s lineup will become the ultimate goal, aiming to connect riders with nearly nondisruptible internet access.
Tesla is building its largest East Coast Supercharger in New York City, planning to bring a 64- to 68-stall station to Queens, New York.
It will end up being tied for the largest Supercharger on the East Coast with this number of stalls. The largest on the Eastern Seaboard is located in Halifax, North Carolina, and is also 68 stalls.

It will also have two pull-through stalls for EVs with trailers. Thx for the pics @LetsCleanNYC. pic.twitter.com/CCo0dIoHin

The location is also set to be fitted with two pull-through stalls for EVs with trailers. We’ve seen Tesla implement these types of parking spots at newer locations as EV ownership continues to expand to those who do more than simply drive their cars.
There are plenty of Superchargers in the New York City metro, but they are mostly located in boroughs outside of Manhattan. There are five Superchargers in various neighborhoods of Manhattan, but there are limited plugs; usually only four per location. There are plenty of Destination Chargers in the Big Apple, though.

Queens, the Bronx, and Brooklyn have become popular locations for companies to build out charging infrastructure for those who live in the highly populated boroughs. There is simply much more real estate to build effective EV charging stations.
The Supercharger will be located in Maspeth, Queens, at 48-26 54th Road. Maspeth has I-495 running through it, so this will be a great location for Tesla owners to hop off the highway on their way to Long Island or to Manhattan to charge up before continuing their journey.
Tesla has done a really great job of expanding its charging footprint throughout the past several years, especially by building large-scale projects that cater to areas that have a high volume of traffic and are main routes of travel to major areas. Tesla is making an effort to make charging less stressful and more widely available in these concentrated regions.

SpaceX just launched a secret payload from California
SpaceX launched a classified Space Force mission from Vandenberg, revealing almost nothing about its payload.
SpaceX launched a classified Falcon 9 mission for the U.S. Space Force from Vandenberg Space Force Base on Saturday night, and the government released almost nothing about what was on board. The mission, designated USSF-366, lifted off from Space Launch Complex 4E with a window that opened at 9:52 p.m. ET and ran into the early hours of Sunday, according to SpaceX’s own mission page, which described the payload only as classified. SpaceX confirmed the launch on its X account and pointed viewers to a livestream that began roughly ten minutes before liftoff.

The lack of detail did not stop analysts from filling in the blanks. Independent tracking of the rocket’s stage drop zones matched the pattern SpaceX has used on previous Starlink Group 15 missions, according to reporting from Outer Space Today, which pointed to Starshield as the likely payload rather than a one off government satellite. Starshield is SpaceX’s national security product, a version of the Starlink satellite bus built to Pentagon specifications for earth observation, communications and hosted payloads. Unlike consumer Starlink, government agencies do not have to disclose what Starshield satellites are actually doing once they reach orbit.
USSF-366 is the latest entry in a steady flow of classified and semi classified work between SpaceX and the Space Force. The company picked up a $178.5 million task order in April to launch missile tracking satellites for the Space Development Agency, as Teslarati reported at the time, and followed that in July with a $1.6 billion award covering 18 more Falcon 9 missions from Vandenberg through the end of 2027, also detailed by Teslarati. Add those contracts up and SpaceX’s Pentagon business for 2026 alone tops $8 billion.
SpaceX scores another massive Pentagon deal to support military satellites
The Falcon 9 that flew Saturday landed back near the launch site, producing the sonic booms that have become routine for residents near Vandenberg. What is less routine is how little the public will likely ever learn about what the rocket carried. SpaceX and the Space Force have not confirmed the Starshield connection, and government satellite programs built on commercial buses rarely get identified beyond a mission number and a general orbit. For a company that live streams almost everything else it does, from Starship test flights to Optimus robot demos, USSF-366 is a reminder that some of SpaceX’s busiest work now happens entirely out of public view.
