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.

Tesla says it denied Musk CEO replacement report before it was published

Tesla says it responded to the WSJ’s request for comment, denying that it was in search of a new CEO to replace Elon Musk.

Tesla said that it denied seeking a replacement for CEO Elon Musk before a report was published claiming the company was considering a new frontman.

Last night, The Wall Street Journal reported that Tesla’s Board of Directors was looking for Musk’s replacement after he had devoted too much time to his role within the government. The publication revised its headline to the report no fewer than five times, initially stating the company was still seeking a replacement.

By the time the headline revisions were complete, it had outlined that Tesla had looked for a replacement a month ago, but had stopped its search following Musk’s commitment to Tesla during the company’s earnings call last month.

Shortly after the report surfaced, Board of Directors chairwoman Robyn Denholm officially issued a statement on behalf of Tesla:

“Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company. This is absolutely false (and this was communicated to the media before the report was published). The CEO of Tesla is Elon Musk and the Board is highly confident in his ability to continue executing on the exciting growth plan ahead.  – Robyn Denholm.”

Tesla Board Chair slams Wall Street Journal over alleged CEO search report

Interestingly, Denholm’s statement indicates it had responded to a request for comment from the Wall Street Journal before the report was published. This is especially interesting because Tesla does not typically respond to media outreach, as it dissolved its media department several years ago.

Tesla typically makes its statements publicly on X.

Musk also responded to the report, indicating that the WSJ had committed an “extremely bad breach of ethics” by publishing a “deliberately false article” that did not include Tesla’s “unequivocal denial beforehand.”

Industry leaders such as Elon Musk have always maintained that autonomous robotaxis will make roads safer. A recent blog post from Waymo about the safety of its self-driving cars suggests that Musk’s sentiments are on point.

Way More Safety

Waymo Driver is already reducing severe crashes and enhancing the safety of vulnerable road users. As per a new research paper set for publication in the Traffic Injury Prevention Journal, Waymo Driver had outperformed human drivers in safety, particularly for vulnerable road users (VRUs).

Over 56.7 million miles, compared to human drivers, Waymo Driver achieved a 92% reduction in pedestrian injury crashes. It also saw 82% fewer crashes with injuries with cyclists and 82% fewer crashes with injuries with motorcyclists. Waymo Driver also slashed injury-involving intersection crashes by 96%, which are a leading cause of severe road harm for human drivers. Waymo Driver saw 85% fewer crashes with suspected serious or worse injuries as well.

What They Are Saying

Mauricio Peña, Waymo’s Chief Safety Officer, was optimistic about Waymo Driver’s results so far. “It’s exciting to see the real positive impact that Waymo is making on the streets of America as we continue to expand. This research reinforces the growing evidence that the Waymo Driver is playing a crucial role in reducing serious crashes and protecting all road users,” the Chief Safety Officer noted.

Jonathan Adkins, Chief Executive Officer at Governors Highway Safety Association, also noted that Waymo’s results are very encouraging. “It’s encouraging to see real-world data showing Waymo outperforming human drivers when it comes to safety. Fewer crashes and fewer injuries — especially for people walking and biking — is exactly the kind of progress we want to see from autonomous vehicles,” Adkins stated.

Tesla hints at June 1 launch of Robotaxi platform in Austin

Tesla has hinted at a potential launch date for the Robotaxi service in Austin, Texas.

Tesla just dropped its biggest hint yet about the potential launch date of its Robotaxi ride-hailing platform in Austin, Texas, shedding more light on when to expect it to take off.

In preparation for the ride-hailing service to launch, Tesla has been in talks with the City of Austin for months. It has also spent recent months bolstering its Full Self-Driving suite, aiming for it to handle initially supervised rides with the use of teleoperators to keep things safe and dependable, at least early on.

The company has also said that it expects the Robotaxi service, which will drive passengers in Tesla Model Y vehicles to start, to launch in Austin in June. However, Tesla has not given an exact date.

Now, Tesla is hinting that Robotaxi could launch on June 1, based on a very vague X post it published on May 1:

Of course, this is extremely speculative. However, it’s the first time Tesla has made any suggestions about a potential launch date, so it’s worth taking it seriously.

While the automaker has often missed timelines in the past, most notably the launch of a “feature-complete” Full Self-Driving platform, this is the first time we’ve seen Tesla be so adamant and truly reiterate a target date.

Tesla has not shied away from this June date for the Robotaxi launch yet, something that is worth noting as we move closer to June. All signs point toward Tesla being able to come through on this timeline, and it could be one of its biggest accomplishments yet on the grand scheme of things. The Robotaxi rollout will be controlled and small to start, the company noted on its most recent Earnings Call.

CEO Elon Musk said:

“The team and I are laser-focused on bringing robotaxi to Austin in June. Unsupervised autonomy will first be solved for the Model Y in Austin.”

At first, it also seems as if the first Robotaxi rides will be available to a select group, as Musk said the ability to order one will not be available to the general public until later in the month. He also said the initial fleet will be between 10 and 20 vehicles:

“Yeah. We’re still debating the exact number to start off on day one, but it’s, like, I don’t know, maybe 10 or 20 vehicles on day one. And watch it carefully. They scale it up rapidly after that. So, we want to make sure that you’re paying very close attention the first time this happens. But, yeah, you will be able to — end of end of June or July, just go to Austin and order a Tesla for autonomous drive.”

While the June 1st date of the Robotaxi launch is extremely speculative, Tesla seems convinced that its vehicles could already handle this task. It would be something to see them come through on this date, especially on the first day of the month.
