SpaceX Starlink satellite internet tested in the field in Antarctica
SpaceX’s Starlink internet continues to find success in Antarctica, Earth’s icy southernmost continent and has spread beyond McMurdo Station.
The company first reported that Starlink reached Antarctica as part of a National Science Foundation experiment in September 2022. The milestone also marked the satellite internet network’s arrival on all seven continents.

A series of lasers
Just ~5% of the almost 3400 working Starlink satellites currently in orbit make coverage of Antarctica (and the Arctic) possible. SpaceX currently has 181 polar-orbiting satellites in operational orbits, likely providing a decent amount of coverage in polar regions. But that’s only a third of the 520 polar satellites SpaceX’s Starlink Gen1 constellation will have once complete, meaning that coverage is likely intermittent for the time being.
Those polar satellites must also use optical interlinks (lasers) to connect Antarctic users to ground stations hundreds or thousands of miles away, as the vast and sparsely populated continent has no Starlink ground stations. Instead, users are connected to the internet via space lasers that route their communications to and from ground stations in South America, Australia, New Zealand, and other nearby locales.
Studying the oldest ice on Earth
The general purpose of the Center for Oldest Ice Exploration (COLDEX) field experiment Starlink is aiding is to find the oldest ice on Earth. That old ice allows scientists to peer back tens of thousands, hundreds of thousands, or even millions of years back into Earth’s past. Most importantly for the modern era, that ice can contain shockingly detailed information about the history of Earth’s climate.
Researchers like Dr. Neff collect ice cores by drilling miles into Antarctic ice sheets. Once removed, packaged, and carefully shipped by plane to labs around the world, the data extracted from those ice cores can tell researchers how the Earth has responded in the past to major and minor changes in climate. Knowing how it has responded and behaved before has helped scientists around the world determine with near certainty that human greenhouse gas emissions are causing average global temperatures to increase at a relatively rapid pace. Further studies, like those being done now, may help specify what kind of changes we can expect as climates warm; allowing cities, countries, and humanity as a whole to prepare for the worst while (hopefully) trying to prevent those outcomes.
COLDEX began testing Starlink in the field in early December 2022. It’s not entirely clear if that testing is still ongoing, but Dr. Peter Neff appears to be optimistic either way. In a January 21st tweet, the assistant professor and field research director said that he was excited “to see how [Starlink] & other modes of high-speed connectivity can advance [science] communication [and]…alter how we do science on the ice.”
Finding a balance
The National Science Foundation has been a part of both Antarctic Starlink experiments, thus far, and finds itself in a unique position. Through funding and other means, the government agency is aiding efforts to test the limits of the SpaceX network and discover how it can benefit science (and improve life) in some of the harshest environments on Earth. Simultaneously, NSF holds a sort of supervisory role over other aspects of SpaceX’s Starlink constellation.
For the most part, that relationship is on an even keel and SpaceX has been highly forthcoming and happy to cooperate. Even without any explicit legal requirement, SpaceX has made wide-reaching changes to its satellites and continues to experiment with ways to reduce their brightness to ground observers and limit their impact on astronomy. Nonetheless, the FCC’s decision to tie SpaceX’s next-generation Starlink Gen2 constellation license with its cooperation with the NSF has given the latter agency a bit more regulatory power than it had before.
That arguably makes the involvement of the NSF (or NSF-funded researchers) in testing Starlink’s ability to benefit science even more important. Knowing firsthand how impactful the ability to access high-bandwidth internet can be in the field and at remote camps, the NSF should be better suited to make the kind of cost-benefit analyses required to determine how much of an impact (on the night sky and astronomy) is acceptable relative to the benefits Starlink can provide.
Tesla rivals are lagging behind the company in alarming fashion in this crucial EV necessity: charging.
Tesla has had a long-standing reputation for having the most expansive electric vehicle charging infrastructure, and even as other companies have launched their own as part of the vehicle manufacturing, nobody seems to keep pace with the EV leader.
A report from Paren exhibited this trend in Q3, showing that Tesla overwhelmingly dominated EV charging stall installations over the past three months. This data is based on U.S. installations, where Tesla has long held a dominating position as the leader in overall electric vehicle sales for many years.
In Q3, Tesla installed 1,820 new chargers in the United States, bringing its total presence to 34,328, an all-time market share of 53.2 percent of all charging stalls in the country.
What’s alarming is the fact that all other networks — ChargePoint, Red E, Electrify America, EV Connect, EVgo, Ionna, Blink, Pilot Flying J, and Rivian Adventure — only installed 841 chargers collectively in Q3. That is nearly 1,000 units behind Tesla, despite there being nine companies contributing as competitors.
These nine networks have 10,055 stalls in total, the data from Paren shows, accounting for 15.6 percent of the chargers in the United States.

EV charging is such a crucial part of the ownership experience, and also a part of the ongoing expansion of EV adoption in the United States.
As more people buy EVs and they become a more prominent form of passenger transportation, more chargers are needed. Many owners charge at home, but charging options in public are important to have for traveling, commuting, and for those who do not have access to residential charging.
With Tesla opening its Supercharger Network to the majority of EV brands over the past two years, things have gotten better.
It has been alarming to see so many companies involved in EV infrastructure essentially accept the gap between Tesla and themselves; not a single company has tried to up its pace to catch up to what Tesla has.
When it comes down to it, as long as there is charging, the manufacturer does not truly matter.
However, it would be nice to see Tesla have some competition in the space, but with its domination and head start in the infrastructure division, it seems the company will have this competitive advantage for years to come.

Tesla updates fans on its plans for the Roadster
Earlier in 2025, Musk said Tesla would host the “most epic demo” for the Roadster in late 2025. We’re in Q4, so time is running out, but we finally got the update we’ve been waiting for from von Holzhausen on the Ride the Lightning podcast yesterday.
Tesla has finally updated fans on its plans for the Roadster after stating earlier this year it would host the “most epic demo,” showcasing the vehicle’s capabilities.
The Roadster is amongst the most highly anticipated automotive releases in the entire industry, and was set for release in 2020 initially. However, Tesla got so caught up with scaling up the Model Y and focusing on autonomy that the project took a figurative backseat.
In the years since its planned release, we have not seen much of the vehicle. Company executives like Elon Musk and Chief Designer Franz von Holzhausen have hinted at things about it and teased us with potential release dates, but each time, it has been delayed.
Last year, Tesla planned to show something, but Musk saw what improvements had been made from the original design unveiled back in 2017 and figured the company could go a step further, only delaying the project another year.
But what’s another year, right?
Earlier in 2025, Musk said Tesla would host the “most epic demo” for the Roadster in late 2025. We’re in Q4, so time is running out, but we finally got the update we’ve been waiting for from von Holzhausen on the Ride the Lightning podcast yesterday.
Confirming the demo was still on for this year, he also teased some new features that the Roadster will have, like new paint options.
Von Holzhausen said:
“I’m excited to showcase the Roadster for a lot of different reasons. The wait will be worth it.”
Additionally, he said the capabilities of the Roadster are truly something, and they have gotten the vehicle to a point that it seems to test the “limits of physics.” Franz added that Tesla has “really gotten to a point where we are going to be achieving that standard that we set out.”
Obviously, the Roadster is not a major contributor to Tesla’s mission or to its future, which mostly leans on artificial intelligence and Robotaxi or autonomy. However, it is still a product that Tesla needs to offer, as many have put massive $250,000 downpayments on the vehicle in an attempt to purchase one.
Tesla has not yet announced a date for its demo of the Roadster, but based on Franz’s interview, it seems the company is still on track to hold that by the end of the year.

Tesla is ramping up its hiring for the Cybercab production team
As can be seen on Tesla’s Careers website, three new Cybercab-related positions are currently available at Giga Texas.
Tesla appears to be ramping up its Cybercab team at Giga Texas. As per recent observations by the Tesla community, three new job listings on the automaker’s Careers site suggest that the company is starting to add more critical personnel for the autonomous two-seater’s production.
New Cybercab jobs
As can be seen on Tesla’s Careers website, three new Cybercab-related positions are currently available. Tesla is looking for a Metrology Technician, who will work on the Cybercab’s Quality team; an Equipment Engineer who will work on the Cybercab’s Plastics team; and a Tool & Die Supervisor, who will work in the Injection Molding team.
All three positions are based in Austin, Texas, which is quite unsurprising as Giga Texas is the only facility today that has the capability to produce the vehicle. The Cybercab’s production is quite different compared to Tesla’s other vehicles, as it is the first car that would be produced using the company’s “Unboxed” process.
Unlike any car that’s produced before
Elon Musk has previously said the Cybercab will be Tesla’s highest-volume vehicle, targeting an annual rate of 2 million units. He also mentioned that the vehicle’s manufacturing line will not resemble an automotive production line at all. Instead, it would resemble a high-speed consumer electronics line, which should pave the way for one Cybercab to be produced every few seconds.
“If you’ve seen the design of the Cybercab line, it doesn’t look like a normal car manufacturing line. It looks like a really high-speed consumer electronics line. In fact, the line will move so fast that actually people can’t even get close to it. I think it’ll be able to produce a car ultimately in less than 5 seconds,” Musk stated during Tesla’s All-Hands meeting earlier this year.
