SpaceX fairing recovery ships return to port with Falcon 9 nosecone and battle scars
Four days after they headed out into the Atlantic Ocean, twin SpaceX fairing recovery ships Ms. Tree and Ms. Chief have returned to port with both halves of a Falcon 9 fairing, although they appear to have picked up some battle scars along the way.
Ms. Tree and its near-identical sibling Ms. Chief departed Port Canaveral on December 14th and arrived on station – 790 km (490 mi) off the coast of Florida – some 36 hours later. Each outfitted with a quartet of arms and pair of nets, it was the first time both ships successfully made it out into the Atlantic for a simultaneous fairing catch attempt, having been foiled by high seas during a prior November outing.
For unknown reasons, after the duo’s November false start, both ships stopped for almost two weeks at a South Carolina port, perhaps indicating that SpaceX was concerned about the structural integrity of the ships’ seemingly fragile net mechanism. In February 2019, Mr. Steven (now Ms. Tree) lost two of its four arms while heading downrange for an attempted catch, apparently broken off by pitching caused by high seas. Further strengthening the case that their net mechanisms are rather fragile, both Ms. Tree and Ms. Chief again suffered damage after their Kacific-1/JCSAT-18 Falcon 9 fairing recovery attempt.
Both ships arrived back at Port Canaveral on December 18th and were caught by Teslarati photographer Richard Angle while passing through the narrow mouth of the port. GO Ms. Chief took the lead, revealing a Falcon 9 fairing half snugly secured with a tarp on her deck – the ship’s very first launch vehicle hardware recovery.
First (partially) successful fairing recovery quite literally under wraps, Ms. Chief nevertheless did not make it through the rite of passage unscathed. Oddly, it appears that just one of the ship’s eight white arm supports is missing (the rear right or aft starboard arm), visibly resulting in the arm slouching a bit compared to its siblings. Intriguingly, it appears that the arm is partially stretching – and thus potentially resting on – Ms. Chief’s net and rigging.
The fact that only one of the arm’s two beams (of eight total) seems to have failed is more immediately indicative of possible human error during installation or a defective attachment mechanism, although it’s entirely possible that a fluke of weather could have damaged just the one beam.
Thankfully, Ms. Tree (formerly Mr. Steven) appears to have made it through the recovery mission with all four arms fully intact, although the ship clearly struggled with a separate mechanism. Notably, Ms. Tree seems to have struggled to use its secondary net to lift its fairing half out of the sea and onto her deck, with that smaller net clearly suffering a multitude of rips and tears at some point during the process. Her recovered fairing half is somewhat awkwardly strewn on the deck with no obvious attempt to rectify the issue, indicating that the net may have torn mid-lift, causing the fairing to fall maybe 5-10 feet.
If it did actually fall onto Ms. Tree’s deck, that will almost certainly be visible in the form of damage to its aluminum-composite honeycomb structure and white insulation coating.
Ultimately, fairing recovery continues to prove itself to be a major challenge, although SpaceX obviously has no intention of giving up. With two successful catches already in hand, it’s clear that fairing recovery is undeniably possible and is more a matter of tweaking existing systems than starting from scratch. Much like Falcon 9 booster recovery had and its fair share of failed landings even after the first success, it will likely take quite a while for SpaceX to optimize fairing recovery to the point that it can be considered reliable.
For now, routine fairing recovery and reuse will likely continue to be Falcon 9’s white whale, at worst adding to the excitement of every SpaceX satellite launch.

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.”
