SpaceX Falcon 9 booster spotted in Southern California on journey to Florida
On August 20th, a member of a local California Facebook group happened to spot a SpaceX Falcon 9 booster in transit, an exceedingly rare sight as of late. Moving east, the booster is almost certainly heading to Florida to support a major cluster of 6-8 launches in Q4 2019.
This marks the first time in nearly four months that a flight-proven Falcon 9 booster has been spotted in transit, excluding a lone (unflown) booster captured on its way to McGregor, Texas last month. This also serves as an opportunity to reexamine the status of SpaceX’s expansive fleet of reusable Falcon 9 Block 5 rockets as the company prepares for a busy end of 2019 in the midst of a rare multi-month lull in launch activities.
Based on the timing, its location (Southern California), and the direction it was headed (Eastbound), the rocket spotted on August 20th is almost certainly twice-flown Falcon 9 booster B1051. The booster was likely departing SpaceX’s Vandenberg Air Force Base (VAFB) launch facilities after some two months post-launch inspections and refurbishment, having completed its second launch and landing on June 12th, 2019 in support of the Radarsat Constellation Mission (RCM).
Prior to its successful launch of RCM, B1051 had the historic privilege of supporting the inaugural orbital launch of SpaceX’s Crew Dragon spacecraft, putting the next-gen crew capsule through its paces before a crewed launch debut expected to occur absolutely no earlier than (NET) December 2019. Known as DM-1 (Demo-1), B1051 was subjected to an exceptionally strenuous suite of inspections, analysis, and testing for the mission – from the very first welding sparks to the booster’s McGregor, TX and Florida static fires and launch debut.
Said debut occurred on March 2nd, 2019, after which B1051 landed at sea aboard drone ship Of Course I Still Love You (OCISLY).
SpaceX production experienced an exceptionally frenetic period from early-2018 to mid-2019, in which the company averaged the completion of almost an entire Falcon 9 or Heavy rocket every 1-2 months, building, delivering, launching, and relaunching Falcon boosters B1046 through B1057 from ~January 2018 to April 2019. In the last 3-4 months, the (publicly visible) rate of rocket production has dramatically slowed, presumably an intentional slow-down triggered by SpaceX’s rapidly growing fleet of flight-proven boosters.
In the last four or so months, unaffiliated observers have spotted a grand total of one new Falcon 9 booster on its way from SpaceX’s Hawthorne, CA factory to its McGregor, TX testing facilities. That booster – likely either B1058 for Crew Dragon’s crewed launch debut (Demo-2) or B1059 for SpaceX’s next USAF GPS III launch – was spotted twice headed east in Arizona on July 29th. Prior to that, the next most recent ‘core spottings’ occurred in mid-to-late April, while the most recent since July 29th’s instance is B1051.2’s August 20th appearance. In short, things are unusually quiet on the SpaceX booster transport front.
Rocket fleet logistics
This apparent slowdown in production can be relatively easily explained by the nature of SpaceX’s fleet of boosters, as well as the company’s growing confidence in the extreme reusability nominally permitted by Falcon 9’s Block 5 upgrade. Just a few days ago, SpaceX Vice President of Build and Flight Reliability Hans Koenigsmann reiterated the belief that Falcon 9 Block 5 boosters will be more than capable of safely performing 10 or more launches apiece.
At the moment, SpaceX’s fleet of flightworthy Block 5 boosters is seven strong, composed of B1046.3, B1048.3, B1049.3, B1051.2, B1052.2, B1053.2, B1056.2. Altogether, they have supported a full 17 launches in 15 months, averaging 2.4 launches apiece with a maximum of three launches achieved by three separate boosters. Under the extremely conservative assumption that 60-90 days are needed for post-flight inspections and refurbishment, anywhere from 2-6 of those boosters are already ready for their next launches.
In simple terms, it appears that even a fleet as small as seven Falcon 9 Block 5 boosters may be capable of supporting a vast majority of SpaceX’s commercial launch contracts, while even NASA has come to support launching uncrewed Cargo Dragon missions on flight-proven boosters. In fact, Koenigsmann revealed that a number of customers had nearly come a full 180 degrees in the less than three years that SpaceX has been reflying boosters. Many now actively prefer a flight-proven booster and have come to view them as a more known quantity relative to unproven (i.e. new) hardware.
Aside from a handful of customers – primarily the US military – that explicitly demand new hardware, the rare need for entirely expendable Falcon 9 launches, and the equally rare loss of boosters during unsuccessful landings, SpaceX just doesn’t need nearly as high of a Falcon 9 or Heavy booster production rate to support the same (or even greater) launch cadences.

Elon Musk says he’s open to powering Apple’s Siri with xAI’s Grok
Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.
Elon Musk says he’s willing to help Apple overhaul Siri by integrating xAI’s Grok 4.1, igniting widespread excitement and speculations about a potential collaboration between the two tech giants.
Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.
Musk open to an Apple collaboration
Musk’s willingness to team up with Apple surfaced after an X user suggested replacing Siri with Grok 4.1 to modernize the AI assistant. The original post criticized Siri’s limitations and urged Apple to adopt a more advanced AI system. “It’s time for Apple to team up with xAI and actually fix Siri. Replace that outdated, painfully dumb assistant with Grok 4.1. Siri deserves to be Superintelligent,” the X user wrote.
Musk quoted the post, responding with, “I’m down.” Musk’s comment quickly attracted a lot of attention among X’s users, many of whom noted that a Grok update to Siri would be appreciated because Apple’s AI assistant has legitimately become terrible in recent years. Others also noted that Grok, together with Apple’s potential integration of Starlink connectivity, would make iPhones even more compelling.
Grok promises major Siri upgrades
The enthusiasm stems largely from Grok 4.1’s technical strengths, which include stronger reasoning and improved creative output. xAI also designed the model to reduce hallucinations, as noted in a Reality Tea report. Supporters believe these improvements could address Apple’s reported challenges developing its own advanced AI systems, giving Siri the upgrade many users have waited years for.
Reactions ranged from humorous to hopeful, with some users joking that Siri would finally “wake up with a personality” if paired with Grok. Siri, after all, was a trailblazer in voice assistants, but it is currently dominated by rivals in terms of features and capabilities. Grok could change that, provided that Apple is willing to collaborate with Elon Musk’s xAI.

Tesla’s top-rated Supercharger Network becomes Stellantis’ new key EV asset
The rollout begins in North America early next year before expanding to Japan and South Korea in 2027.
Stellantis will adopt Tesla’s North American Charging System (NACS) across select battery-electric vehicles starting in 2026, giving customers access to more than 28,000 Tesla Superchargers across five countries.
The rollout begins in North America early next year before expanding to Japan and South Korea in 2027, significantly boosting public fast-charging access for Jeep, Dodge, and other Stellantis brands. The move marks one of Stellantis’ largest infrastructure expansions to date.
Stellantis unlocks NACS access
Beginning in early 2026, Stellantis BEVs, including models like the Jeep Wagoneer S and Dodge Charger Daytona, will gain access to Tesla’s Supercharger network across North America. The integration will extend to Japan and South Korea in 2027, with the 2026 Jeep Recon and additional next-generation BEVs joining the list as compatibility expands. Stellantis stated that details on adapters and network onboarding for current models will be released closer to launch, as noted in a press release.
The company emphasizes that adopting NACS aligns with a broader strategy to give customers greater freedom of choice when charging, especially as infrastructure availability becomes a deciding factor for EV buyers. With access to thousands of high-speed stations, Stellantis aims to reduce range anxiety and improve long-distance travel convenience across its global portfolio.
Tesla Supercharger network proves its value
Stellantis’ move also comes as Tesla’s Supercharger system continues to earn top rankings for reliability and user experience. In the 2025 Zapmap survey, drawn from nearly 4,000 BEV drivers across the UK, Tesla Superchargers were named the Best Large EV Charging Network for the second year in a row. The study measured reliability, ease of use, and payment experience across the country’s public charging landscape.
Tesla’s UK network now includes 1,115 open Supercharger devices at 97 public locations, representing roughly 54% of its total footprint and marking a 40% increase in public availability since late 2024. Zapmap highlighted the Supercharger network’s consistently lower pricing compared to other rapid and ultra-rapid providers, alongside its strong uptime and streamlined user experience. These performance metrics further reinforce the value of Stellantis’ decision to integrate NACS across major markets.

Tesla FSD and Robotaxis are making people aware how bad human drivers are
These observations really show that Tesla’s focus on autonomy would result in safer roads for everyone.
Tesla FSD and the Robotaxi network are becoming so good in their self-driving performance, they are starting to highlight just how bad humans really are at driving.
This could be seen in several observations from the electric vehicle community.
Robotaxis are better than Uber, actually
Tesla’s Robotaxi service is only available in Austin and the Bay Area for now, but those who have used the service have generally been appreciative of its capabilities and performance. Some Robotaxi customers have observed that the service is simply so much more affordable than Uber, and its driving is actually really good.
One veteran Tesla owner, @BLKMDL3, recently noted that the Robotaxi service has become better than Uber simply because FSD now drives better than some human drivers. Apart from the fact that Robotaxis allow riders to easily sync their phones to the rear display, the vehicles generally provide a significantly more comfortable ride than their manually-driven counterparts from Uber.
FSD is changing the narrative, one ride at a time
It appears that FSD V14 really is something special. The update has received wide acclaim from users since it was released, and the positive reactions are still coming. This was highlighted in a recent post from Tesla owner Travis Nicolette, who shared a recent experience with FSD. As per the Tesla owner, he was quite surprised as his car was able to accomplish a U-turn in a way that exceeded human drivers.
Yet another example of FSD’s smooth and safe driving was showcased in a recent video, which showed a safety monitor of a Bay Area Robotaxi falling asleep in the driver’s seat. In any other car, a driver falling asleep at the wheel could easily result in a grave accident, but thanks to FSD, both the safety monitor and the passengers remained safe.
These observations, if any, really show that Tesla’s focus on autonomy would result in safer roads for everyone. As per the IIHS, there were 40,901 deaths from motor vehicle crashes in the United States in 2023. The NHTSA also estimated that in 2017, 91,000 police-reported crashes involved drowsy drivers. These crashes led to an estimated 50,000 people injured and 800 deaths. FSD could lower all these tragic statistics by a notable margin.
