SpaceX lifts soggy Falcon 9 Block 5 booster ashore after accidental splashdown
Independent group USLaunchReport has published a video capturing the entirety of SpaceX’s ad hoc East Coast Falcon 9 recovery operations, in which forlorn booster B1050 had to be carefully extracted out of the ocean after an unintentional soft-landing in the Atlantic following its successful Dec. 5 launch debut.
72 hours after B1050’s water landing and some painstaking preparation, the booster was towed to SpaceX’s dock space in Port Canaveral, where it spent just a brief few hours floating adjacent to drone ship Of Course I Still Love You and the rest of the company’s Florida fleet. Considerably less than twelve hours after arriving, technicians had already managed to lift the rocket out of the ocean and onto dry land, where another week or so was spent preparing Falcon 9 for transport.
Given the extent of the damage to the Block 5 booster’s interstage and the basic fact that SpaceX recovery technicians and engineers had never attempted anything quite like it before, it was fairly impressive that they took barely six hours to lift the booster out of the water, particularly considering that the rocket appeared to be filled with hundreds or even thousands of gallons of water. No visible damage was caused, although there was clearly some cause for extensive discussion and preparation per an unusually large and lengthy huddle of more than 30 employees prior to the beginning of the lift.

Once on land, B1050 had an unusual sling placed exactly where the Falcon 9 booster’s liquid oxygen (LOx) and kerosene (RP-1) propellant tanks were welded together, apparently a location that is particularly sensitive to off-nominal X-axis stress. To give context, imagine bending a cardboard tube or straw in half instead of trying to push its ends together – Falcon 9’s structure is quite similar in concept. Built primarily 5mm-thick sheets of lithium-aluminum alloy, Falcon 9’s propellant tanks are extremely thin and light while also being aggressively optimized for vertical (up and down) loading, i.e. the forces experienced while accelerating (and eventually decelerating) through the atmosphere during launch and landing.
As a result, SpaceX almost always pressurizes the first stage propellant tanks of Falcon 9 with nitrogen whenever boosters are horizontal without physical support at their bendy centers. In the case of B1050, SpaceX almost certainly concluded that using its waterlogged umbilical ports to inject nitrogen into its tanks was too much of a risk without knowing the precise condition of the piping and the tanks themselves, opting instead to go with a simple sling to prevent damage from unintended bending. Thankfully, B1050 appears to have made it through its dry land ordeal even better than the time it spent in the Atlantic, suffering no visible damage whatsoever.

Somewhere between December 14 and 15, the booster was at long last lifted onto SpaceX’s primary East Coast booster transporter and carefully drove the rocket to one of its 2-3 Cape Canaveral Air Force Station (CCAFS) refurbishment and storage hangars, avoiding detection by all but a few passersby. This could full well be the last we see (and even hear) of poor old Falcon 9 B1050, but there is still a decent chance that SpaceX hopes the entire rocket or major components can be easily salvaged.
Given the extreme care taken during the booster’s lift onto land and the week it spent having legs and grid fins removed, it can be definitively concluded that an effort will be made to save the entire vehicle (sans interstage). If it has managed to make it through the past two weeks largely unscathed, it may well become the first Falcon 9 to conduct a dedicated launch of multiple Starlink satellites sometime in the second half of 2019, at least according to CEO Elon Musk’s vague suggestion that it could fly on an “internal SpaceX mission”.

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.”
