SpaceX preparing for back-to-back Starlink launches from California and Florida
Update: Next Spaceflight reports that SpaceX has delayed Starlink 4-15 to 4:38 pm EDT, May 14th, ending the immediate possibility of a new SpaceX record for time between launches.
After a few days of delays pushed the missions closer together, SpaceX is now preparing to launch two batches of 53 Starlink satellites just eight hours apart – one from Florida and the other from California.
Originally scheduled to launch as early May 10th, which would have tied SpaceX’s Vandenberg Space Force Base (VSFB) SLC-4E launch pad turnaround record, Starlink 4-13 slipped to May 12th within the last few days. 2400 miles (~3900 km) to the east, SpaceX’s Starlink 4-15 mission – preparing to launch from the company’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad – recently found itself in the opposite boat.
On April 22nd, Spaceflight Now reported that Starlink 4-15 was scheduled to launch no earlier than (NET) May 8th. At the time, Starlink 4-13 was also scheduled to launch on the 8th, placing the two Starlink missions just a few hours apart. On April 28th, Spaceflight Now updated its well-sourced launch calendar, revealing that Starlink 4-13 had slipped to May 10th and Starlink 4-15 to May 16th, ending their concurrence. Finally, on May 7th and May 8th, photographer Ben Cooper reported that Starlink 4-15 had moved up to 2:08 am EDT (06:08 UTC), May 13th and FAA documents revealed that Starlink 4-13 had slipped again to 3:29 pm PDT (22:29 UTC), May 12th.
In other words, the missions have again found themselves just a handful of hours apart after weeks of unrelated juggling and delays. Barring additional issues, Starlink 4-13 and Starlink 4-15 are scheduled to launch just 7 hours and 41 minutes apart. Set in late 2021, the shortest time between two Falcon launches is currently 15 hours and 17 minutes. But above all else, the constant back and forth – only to end up with both launches again just hours apart – demonstrates just how agonizing and unforgiving the planning behind every rocket launch schedule truly is.
Fittingly, Starlink 4-13’s drone ship headed to sea just ~60 hours before the scheduled launch and Starlink 4-15’s drone ship has yet to depart, keeping the launch dates of both missions about as uncertain as they can be without guaranteeing that delays are coming. Both drone ships must be towed about 400 miles downrange at speeds that almost never exceed 8-10 mph, translating to a minimum two-day journey even with zero stops, slowdowns, or detours.
Beyond the record-breaking potential, Starlink 4-13 is an otherwise ordinary mission that will launch another 53 Starlink V1.5 satellites to an ordinary 53.2-degree inclination, which simply means that they’ll end up in the same ‘shell’ as the other satellites in Starlink’s ‘Group 4’ shell. Despite launching from the opposite coast of the US, Starlink 4-15 will be almost identical and is expected to deploy another 53 Starlink V1.5 satellites to the same orbital shell. However, it appears that Starlink 4-15 will have a few highly unusual features.
Instead of performing a hockey stick-like ‘dogleg’ maneuver to avoid overflying any populated islands in the Bahamas, Falcon 9 will directly overfly the country’s largest western island and attempt to land right in the middle of the archipelago, potentially touching down on a drone ship just 5-15 miles away from Nassau and a couple other islands. The fact alone that SpaceX was able to convince both the Bahamas and the US’ FAA to allow it to fly the trajectory shown above is extremely impressive and belies a deep trust in SpaceX’s expertise and Falcon 9’s safety and reliability. At the same time, SpaceX may be taking some degree of risk, as the trajectory’s minuscule margins for error probably mean that Falcon 9’s automatic flight termination system will be programmed to destroy the rocket at the slightest hint of deviation from the planned trajectory.
Adding to the oddity, Starlink 4-15 will be the first in a long line of 45 dedicated Starlink launches to debut a new Falcon 9 booster. According to Next Spaceflight, Falcon 9 B1073 will claim that unusual first, almost entirely flipping the table on the precedent of conservative government customers – still timid about SpaceX reusability – scrambling to secure increasingly rare launch opportunities on new Falcon 9 boosters. Alternatively, it’s possible – but unlikely – that SpaceX implemented significant changes to Falcon 9 B1073 that it wants to verify independently before risking customer payloads.
With any luck, the new rocket will perform flawlessly and give some nearby Bahamians a truly one-of-a-kind experience: the ability to watch a SpaceX Falcon 9 booster land at sea… from the comfort of their own homes.

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.”
