SpaceX sends Starlink satellites, Boeing demonstrator into orbit on 40th launch of 2022
SpaceX has completed its 40th Falcon 9 launch of 2022, delivering a new batch of Starlink satellites and Boeing demonstration satellite into orbit.
Right on schedule, Falcon 9 lifted off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad at 10:09 pm EDT, Sunday, September 4th. The rocket’s reused booster and fairing and new upper stage performed as expected, continuing Falcon 9’s unprecedented streak of 149 successful launches. Flying for the seventh time overall, former Falcon Heavy booster B1052 performed flawlessly after a quick 31-day turnaround and touched down on SpaceX drone ship Just Read The Instructions’ (JRTI) deck several hundred miles downrange less than nine minutes after liftoff.
Flying for the fourth and fifth times, the Starlink 4-20 mission’s Falcon 9 fairing halves also worked as expected on ascent. SpaceX does not discuss fairing recovery but both halves likely deployed parafoils after reenter Earth’s atmosphere and gently splashed down in the Atlantic Ocean. SpaceX support ship Doug will eventually fish them out of the water for reuse.
Not merely a Starlink mission, Starlink 4-20 was SpaceX’s sixth Starlink rideshare. Sitting atop the stack of 51 Starlink V1.5 satellites was an experimental spacecraft built by Spaceflight Inc. Known as Sherpa-LTC2, Spaceflight and partner Astro Digital turned the orbital transfer vehicle (space tug) into a satellite for customer Boeing. The purpose: carry and test a prototype communications payload built by Astro Digital and designed to verify new V-band communications technologies for a planned constellation of Boeing satellites in Low Earth Orbit (LEO).
The US Federal Communications Commission (FCC) approved Boeing’s plans for a 147-satellite V-band constellation in November 2021. It’s unclear what the purpose of the constellation would be or if Boeing already has customers or partners lined up. The prototype spacecraft built by Spaceflight and Astro Digital – known as Varuna in recent FCC filings – will be crucial for determining the constellation’s future. Boeing wants to use a swath of spectrum known as the V-band that has a higher frequency than the Ku and Ka bands commonly used by most other communications satellites. A higher frequency could mean higher connection speeds and more available bandwidth, but V-band radio waves tend to struggle to pierce through rain and other adverse weather conditions.
Varuna should help Boeing fully determine whether that interference is a showstopper or something that can be managed. Boeing applied for an FCC license for its V-band constellation in 2017. It’s unclear whether a lack of interest on Boeing’s part or problems with the application caused the process to take as long as it did.
Varuna was successfully deployed from Falcon 9 a bit less than 50 minutes later in a mostly circular orbit 316 kilometers (196 mi) above Earth’s surface. Outfitted with a propulsion system designed by startup Benchmark Space, Sherpa-LTC2 is meant to eventually raise itself into an operational orbit around 1050 kilometers (~650 mi), where the V-band payload can be tested at the same altitude as Boeing’s planned constellation.
20 minutes after Varuna’s deployment, Falcon 9’s upper stage – spinning end over end – released all 51 Starlink satellites at once, completing the payload portion of the mission. As always, the upper stage will likely perform a deorbit burn within a few hours of liftoff and should reenter Earth’s atmosphere not long after, ensuring that the only space debris produced by the mission is the Varuna deployment mechanism and a set of four benign Starlink ‘tensioning rods’ that should reenter in about two months.
Starlink 4-20 was SpaceX’s 40th launch of 2022 and 50th launch in 12 months. According to Next Spaceflight, the company has plans for at least two more Starlink launches within the next eight days. Starlink 4-2, another rideshare mission, is scheduled no earlier than September 10th, while Starlink 4-34 could launch on September 12th.

Swedish unions consider police report over Tesla Megapack Supercharger
The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm.
Swedish labor unions are considering whether to file a police report related to a newly opened Tesla Megapack Supercharger near Stockholm, citing questions about how electricity is supplied to the site. The matter has also been referred to Sweden’s energy regulator.
Tesla Megapack Supercharger
The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm. Unlike traditional charging stations, the site is powered by an on-site Megapack battery rather than a direct grid connection. Typical grid connections for Tesla charging sites in Sweden have seen challenges for nearly two years due to union blockades.
Swedish labor union IF Metall has submitted a report to the Energy Market Inspectorate, asking the authority to assess whether electricity supplied to the battery system meets regulatory requirements, as noted in a report from Dagens Arbete (DA). The Tesla Megapack on the site is charged using electricity supplied by a local company, though the specific provider has not been publicly identified.
Peter Lydell, an ombudsman at IF Metall, issued a comment about the Tesla Megapack Supercharger. “The legislation states that only companies that engage in electricity trading may supply electricity to other parties. You may not supply electricity without a permit, then you are engaging in illegal electricity trading. That is why we have reported this… This is about a company that helps Tesla circumvent the conflict measures that exist. It is clear that it is troublesome and it can also have consequences,” Lydell said.
Police report under consideration
The Swedish Electricians’ Association has also examined the Tesla Megapack Supercharger and documented its power setup. As per materials submitted to the Energy Market Inspectorate, electrical cables were reportedly routed from a property located approximately 500 meters from the charging site.
Tomas Jansson, ombudsman and deputy head of negotiations at the Swedish Electricians’ Association, stated that the union was assessing whether to file a police report related to the Tesla Megapack Supercharger. He also confirmed that the electricians’ union was coordinating with IF Metall about the matter. “We have a close collaboration with IF Metall, and we are currently investigating this. We support IF Metall in their fight for fair conditions at Tesla,” Jansson said.

Tesla HW4.5 spotted in new Model Y, triggers speculation
Owners taking delivery of recent Model Y builds have identified components labeled “AP45.”
Tesla’s Hardware 4.5 computer appears to have surfaced in newly delivered Model Y vehicles, prompting fresh speculation about an interim upgrade ahead of the company’s upcoming AI5 chip.
Owners taking delivery of recent Model Y builds have identified components labeled “AP45,” suggesting Tesla may have quietly started rolling out revised autonomy hardware.
Hardware 4.5 appears in new Model Y units
The potential Hardware 4.5 sighting was first reported by Model Y owner @Eric5un, who shared details of a Fremont-built 2026 Model Y AWD Premium delivered this January. As per the Model Y owner, the vehicle includes a new front camera housing and a 16-inch center display, along with an Autopilot computer labeled “AP45” and part number 2261336-02-A.
The Tesla owner later explained that he confirmed the part number by briefly pulling down the upper carpet liner below the Model Y’s glovebox. Other owners soon reported similar findings. One Model Y Performance owner noted that their December build also appeared to include Hardware 4.5, while another owner of an Austin-built Model Y Performance reported spotting the same “AP45” hardware.
These sightings suggest that Tesla may already be installing revised FSD computers in its new Model Y batches, despite the company not yet making any formal announcements about Hardware 4.5.
What Hardware 4.5 could represent
Clues about Hardware 4.5 have surfaced previously in Tesla’s Electronic Parts Catalog. As reported by NotATeslaApp, the catalog has listed a component described as “CAR COMPUTER – LEFT HAND DRIVE – PROVISIONED – HARDWARE 4.5.” The component, which features the part number 2261336-S2-A, is priced at $2,300.00.
Longtime Tesla hacker @greentheonly has noted that Tesla software has contained references to a possible three-SoC architecture for some time. Previous generations of Tesla’s FSD computer, including Hardware 3 and Hardware 4, use a dual-SoC design for redundancy. A three-SoC layout could allow for higher inference throughput and improved fault tolerance.
Such an architecture could also serve as a bridge to AI5, Tesla’s next-generation autonomy chip expected to enter production later in 2026. As Tesla’s neural networks grow larger and more computationally demanding, Hardware 4.5 may provide additional headroom for vehicles built before AI5 becomes widely available.

Elon Musk’s Grokipedia is getting cited by OpenAI’s ChatGPT
Some responses generated by OpenAI’s ChatGPT have recently referenced information from Grokipedia.
Some responses generated by OpenAI’s ChatGPT have recently referenced information from Grokipedia, an AI-generated encyclopedia developed by rival xAI, which was founded by Elon Musk. The citations appeared across a limited set of queries.
Reports about the matter were initially reported by The Guardian.
Grokipedia references in ChatGPT
Grokipedia launched in October as part of xAI’s effort to build an alternative to Wikipedia, which has become less centrist over the years. Unlike Wikipedia, which is moderated and edited by humans, Grokipedia is purely AI-powered, allowing it to approach topics with as little bias as possible, at least in theory. This model has also allowed Grokipedia to grow its article base quickly, with recent reports indicating that it has created over 6 million articles, more than 80% of English Wikipedia.
The Guardian reported that ChatGPT cited Grokipedia nine times across responses to more than a dozen user questions during its tests. As per the publication, the Grokipedia citations did not appear when ChatGPT was asked about high-profile or widely documented topics. Instead, Grokipedia was referenced in responses to more obscure historical or biographical claims. The pattern suggested selective use rather than broad reliance on the source, at least for now.
Broader Grokipedia use
The Guardian also noted that Grokipedia citations were not exclusive to ChatGPT. Anthropic’s AI assistant Claude reportedly showed similar references to Grokipedia in some responses, highlighting a broader issue around how large language models identify and weigh publicly available information.
In a statement to The Guardian, an OpenAI spokesperson stated that ChatGPT “aims to draw from a broad range of publicly available sources and viewpoints.” “We apply safety filters to reduce the risk of surfacing links associated with high-severity harms, and ChatGPT clearly shows which sources informed a response through citations,” the spokesperson stated.
Anthropic, for its part, did not respond to a request for comment on the matter. As for xAI, the artificial intelligence startup simply responded with a short comment that stated, “Legacy media lies.”
