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.

Each Starlink V1.5 satellite has several laser link terminals that allow the constellation to create a mesh network in space and reach even the remotest users. (SpaceX)

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.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.

He said:

“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”

At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:

“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”

The Hardware

Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.

It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.

ACM3 specs include:

  • 1600 sparse INT8 TOPS (Trillion Operations Per Second).
  • The processing power of 5 billion pixels per second.
  • RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
  • RAP1 is enabled by an in-house developed AI compiler and platform software

As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”

More Details

Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.

Tesla owners in California, Oregon, and Arizona can now use Lemonade Insurance, the firm that recently said it could cover Full Self-Driving miles for “almost free.”

Lemonade, which offered the new service through its app, has three distinct advantages, it says:

  • Direct Connection for no telematics device needed
  • Better customer service
  • Smarter pricing

The company is known for offering unique, fee-based insurance rates through AI, and instead of keeping unclaimed premiums, it offers coverage through a flat free upfront. The leftover funds are donated to charities by its policyholders.

On Thursday, it announced that cars in three states would be able to be connected directly to the car through its smartphone app, enabling easier access to insurance factors through telematics:

Tesla recently was offered “almost free” coverage for Full Self-Driving by Lemonade’s Shai Wininger, President and Co-founder, who said it would be “happy to explore insuring Tesla FSD miles for (almost) free.”

The strategy would be one of the most unique, as it would provide Tesla drivers with stable, accurate, and consistent insurance rates, while also incentivizing owners to utilize Full Self-Driving for their travel miles.

Tesla Full Self-Driving gets an offer to be insured for ‘almost free’

This would make FSD more cost-effective for owners and contribute to the company’s data collection efforts.

Data also backs Tesla Full Self-Driving’s advantages as a safety net for drivers. Recent figures indicate it was nine times less likely to be in an accident compared to the national average, registering an accident every 6.36 million miles. The NHTSA says a crash occurs approximately every 702,000 miles.

Tesla also offers its own in-house insurance program, which is currently offered in twelve states so far. The company is attempting to enter more areas of the U.S., with recent filings indicating the company wants to enter Florida and offer insurance to drivers in that state.

Tesla Model Y gets hefty discounts and more in final sales push

Tesla Model Y configurations are getting hefty discounts and more benefits as the company is in the phase of its final sales push for the year.

Tesla is offering up to $1,500 off new Model Y Standard trims that are available in inventory in the United States. Additionally, Tesla is giving up to $2,000 off the Premium trims of the Model Y. There is also one free upgrade included, such as a paint color or interior color, at no additional charge.

Tesla is hoping to bolster a relatively strong performance through the first three quarters of the year, with over 1.2 million cars delivered through the first three quarters.

This is about four percent under what the company reported through the same time period last year, as it was about 75,000 vehicles ahead in 2024.

However, Q3 was the company’s best quarterly performance of all time, and it surged because of the loss of the $7,500 EV tax credit, which was eliminated in September. The imminent removal of the credit led to many buyers flocking to Tesla showrooms to take advantage of the discount, which led to a strong quarter for the company.

2024 was the first year in the 2020s when Tesla did not experience a year-over-year delivery growth, as it saw a 1 percent slide from 2023. The previous years saw huge growth, with the biggest coming from 2020 to 2021, when Tesla had an 87 percent delivery growth.

This year, it is expected to be a second consecutive slide, with a drop of potentially 8 percent, if it manages to deliver 1.65 million cars, which is where Grok projects the automaker to end up.

Tesla will likely return to its annual growth rate in the coming years, but the focus is becoming less about delivery figures and more about autonomy, a major contributor to the company’s valuation. As AI continues to become more refined, Tesla will apply these principles to its Full Self-Driving efforts, as well as the Optimus humanoid robot project.

Will Tesla thrive without the EV tax credit? Five reasons why they might

These discounts should help incentivize some buyers to pull the trigger on a vehicle before the year ends. It will also be interesting to see if the adjusted EV tax credit rules, which allowed deliveries to occur after the September 30 cutoff date, along with these discounts, will have a positive impact.
