On Wednesday, November 3, a United Launch Alliance (ULA) Atlas V 531 rocket was set to launch the NROL-101 mission – a classified payload for the National Reconnaissance Office (NRO) of the United States government – from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station. At neighboring Space Launch Complex 40 (SLC-40) a SpaceX Falcon 9 stood ready and waiting to launch a US military GPS satellite just a day later.

Ultimately, due to an anomaly with launchpad ground support equipment, the ULA launch attempt of the Atlas V NROL-101 mission was scrubbed Wednesday evening. Admittedly, the weather did not look promising either with ground winds remaining a concern throughout the countdown window.

With an hour and forty-seven minutes to go – just five seconds after a planned fifteen-minute hold was released – the launch teams announced that an anomaly had been discovered with “a ground valve issue with the liquid oxygen system for the Atlas V first stage.” The discovery initiated an immediate stop to the countdown and launch teams entered into an unplanned hold that would delay the targeted launch time.

At first, ULA conducted remote troubleshooting, but the anomaly was not remedied and a return-to-pad team would be required to enter the secured launchpad to physically investigate.

An anomaly team was deployed to investigate the valve that was restricting the flow of liquid oxygen (LOx) to the first stage of the Atlas V rocket. The hold remained for over an hour allowing the propellant lines to warm to a temperature that would be needed to be re-cooled prior to resuming the countdown.

Eventually, the return-to-pad team was able to evacuate the pad securing it for launch once again. Chill-down procedures to return the propellant lines back to an operational temperature began but were halted almost immediately. The anomaly had not been completely rectified and not enough time remained in the launch window to re-address it and re-chill the propellant lines. This led to the scrubbed launch attempt.

Typically, a scrubbed ULA mission for the NRO means that a neighboring SpaceX mission has to wait until the problem is fixed and ULA gets its rocket off of the nearby launchpad. However, that was not the case with Wednesday’s scrub. ULA stood down for a 48 hour recycle – rather than a typical 24 hour recycle – to attempt to launch the Atlas V 531 again on Friday, November 6.

This cleared the way for SpaceX to keep its targeted launch date of Thursday, November 5 during a launch window that extends approximately fifteen minutes from 6:24 – 6:39 p.m. EST (2324-2339 UTC) from SLC-40.

Following a successful static fire test of all nine Merlin 1D engines, SpaceX will attempt to launch the GPSIII-SV04 satellite for the United States military for a second time on Thursday, November 5.

The previous launch attempt on Friday, October 2 was thwarted at T-2 seconds due to anomalous engine start-up behavior. The unexplained early start-up of two Merlin 1D engines was eventually determined to be caused by “unexpected pressure rise in the turbomachinery gas generator” as explained by SpaceX CEO Elon Musk.

The engine anomaly prompted a thorough investigation of all Merlin 1D engines on the launch vehicle, as well as, a thorough investigation of the engines on two Falcon 9 launch vehicles designated for future NASA missions – the first operational rotation mission of the Commercial Crew Program, Crew-1, and the launch of the NASA and European Space Agency Earth-observation satellite, the Micheal Freilich Sentinel-6. Engines were eventually replaced on all three Falcon 9 launch vehicles.

A live hosted webcast of Thursday’s launch attempt will be provided on the company website and is expected to be available for viewing approximately fifteen minuted before liftoff.

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.”
