SpaceX sets Dragon reuse record, debuts drone ship on first launch in two months
Update #2: After a 24-hour weather delay, conditions were far more favorable on August 29th, allowing a SpaceX Falcon 9 rocket to lift off for the first time in almost two months and send a cargo-filled Dragon spacecraft on its way to the International Space Station (ISS).
Aside from marking the end of SpaceX’s longest launch hiatus in two years, CRS-23’s successful liftoff also means that the company has smashed the world record for fastest orbital space capsule reuse. As part of Cargo Dragon 2’s first reuse ever, SpaceX launched Dragon C208 just seven and a half months (227d) after its first orbital reentry and splashdown, handily beating the previous record of 328 days. Additionally, flying for the fourth time, Falcon 9 booster B1064 became the first rocket to land on brand new SpaceX drone ship A Shortfall of Gravitas (ASOG) after sending Dragon C208 on its way to the ISS.

Update: Although the weather forecast has worsened, SpaceX remains on track to attempt its first launch in eight weeks – a mission that will also smash one of the company’s orbital spacecraft reusability records.
While mostly mundane, a system preceding Tropical Storm Ida is producing conditions less than optimal for rocket launches, raising the risk of in-flight lightning strikes and the chances of Falcon 9 and Dragon flying through clouds containing precipitation (rain/ice/etc). Ultimately, that means that there’s just a 40% chance (down from 50% in the last few days) that weather conditions will be favorable for SpaceX to launch CRS-23. Regardless, barring a surprise announcement in the next few hours, it appears that there’s enough of a chance that SpaceX and NASA will still make an attempt.
If all goes according to plan, a flight-proven Falcon 9 rocket will send an upgraded Cargo Dragon on the way to orbit for the second time in seven months – almost twice as fast a turnaround as SpaceX’s ~340-day record for orbital spacecraft reuse. Tune in below around 3:20am EDT (07:20 UTC) to catch the hopeful launch live.
For the first time in more than nine weeks, SpaceX has completed a routine Falcon 9 preflight test known as a static fire and verified that the rocket is ready to launch later this week.
Save for at least one booster qualification test completed at SpaceX’s McGregor, Texas development facilities, Falcon 9’s August 25th static fire is the first since June 22nd. The upgraded Cargo Dragon space station resupply mission the rocket will support will also be SpaceX’s first launch since June 30th – the company’s longest hiatus between launches since a three-month pause that began two years ago.
Now, just a few days before that drought is expected to end, a SpaceX executive has partially explained why the company hasn’t launched a single Falcon rocket in ~60 days after completing a record 20 orbital launches in the first half of 2021.
Speaking at the 2021 Space Symposium on August 24th, SpaceX President and COO Gwynne Shotwell revealed that the company had chosen to pause Starlink missions (representing the vast majority of its 2021 launches) and focus on preparing a new generation of satellites for flight. Believed to be called Starlink V1.5, those new satellites represent a relatively small design change save for one crucial addition: multiple lasers.
All the way back in mid-2018, SpaceX launched its very first pair of Starlink prototype satellites – spacecraft that largely functioned as expected and provided a wealth of data but were almost nothing like the Starlink V0.9 and V1.0 spacecraft SpaceX would eventually start launching in 2019. Nevertheless, they did carry sets of small lasers generally known as optical intersatellite links or OISLs for short. Not radically dissimilar to the hundreds of thousands of miles of fiber optic cables that make up the backbone of the internet, lasers operating in the vacuum of space can effectively mirror the extraordinary bandwidth and performance offered by fiber connections – but wirelessly.
Instead of carefully insulated cables filled with tiny threads of glass, which really just serve as a controlled environment for light-based communications, OISLs enable a similar feat by replacing cables with extraordinarily precise mechanisms capable of aiming lasers with sub-millimeter precision from dozens or hundreds of miles away. As a result, laser interlinks are fairly complex and expensive devices – not something currently economical to install on thousands of satellites mainly focused on affordability.
SpaceX, of course, has wanted to install unprecedentedly affordable laser interlinks on thousands of Starlink satellites for as long as the constellation has been publicly discussed. If realized, it would create an extraordinary orbital mesh network that would allow Starlink to self-route a large portion of user communications without the need for a colossal network of tens of thousands of ground stations covering every inch of Earth – land, sea, ice, and all. A Starlink constellation with near-universal laser interlinks could also potentially allow the constellation to not only match – but beat by a large margin – the latency of best-case terrestrial fiber-optic connections.
After effectively completing Starlink’s first ‘shell’ of satellites earlier this year, SpaceX shifted its focus to preparing for polar Starlink launches from both its west and east coast facilities. While the first shell lacked interlinks entirely, SpaceX appears to have decided that all polar Starlink satellites will be launched with its own custom-built space lasers, even if that means delaying Starlink launches until those lasers are ready for action. Due to the fact that the vast majority of SpaceX’s launches as of late have been its own Starlink missions, the company’s Falcon rockets simply haven’t had anything to launch.
That should change on August 28th, when a thrice-flown Falcon 9 booster launches a refurbished spacecraft on its second orbital space station resupply – a first for SpaceX’s upgraded Cargo Dragon 2 vehicle. A Shortfall of Gravitas (ASOG), SpaceX’s newest drone ship, will also be supporting its first Falcon landing ever as part of CRS-23, hopefully recovering Falcon 9 booster B1064 for a fifth launch later this year.
Tune in around 3:20am (07:20 UTC) on Saturday, August 28th to watch SpaceX’s first launch in two months live.

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.”
