SpaceX Falcon 9 Block 5 rocket’s drone ship return captured in stunning detail [gallery]
Teslarati photographer Pauline Acalin has captured SpaceX’s first West Coast Falcon 9 Block 5 booster recovery in the best detail yet seen of the rocket upgrade, well-worn after its first successful launch of Iridium NEXT-7, July 25.
Iridium-7 marked a number of important debuts for SpaceX: Falcon 9 Block 5 (Booster 1048, in this case) completed its first West Coast launch from SpaceX’s Vandenberg pad, drone ship Just Read The Instructions’ (JRTI) first rocket recovery attempt and success in nearly ten months, and recovery vessel Mr Steven’s first (albeit unsuccessful) attempt at catching a Falcon fairing with a dramatically enlarged net and arms.

Although inclement wind conditions foiled Mr Steven’s fairing catch effort and put pressure on Falcon 9 B1048’s journey to JRTI, Iridium-7 was flawlessly placed in orbit and Falcon 9 managed a slightly off-center but still thoroughly successful landing on the drone ship off the coast of California. With that launch and land debut on the West Coast and a second successful East Coast launch of a Block 5 rocket to the East just a few days prior, SpaceX has effectively demonstrated the basic functionality and reliability of the upgrade’s many far-reaching changes to the underlying Falcon 9 architecture.

Just Read The Instructions recovers a rocket
After nearly ten months largely spent berthed at SpaceX’s original Port of San Pedro dock space, drone ship JRTI has at long last returned to sea and successfully recovered a Falcon 9 booster, this time marking the West Coast launch and landing debut of the Block 5 rocket. Photos of the drone ship and rocket’s return to port were some of the best ever seen, thanks largely to the port’s layout and narrow mouth, which allowed Teslarati photographer Pauline Acalin to put giant telephoto lenses and a unique top-down perspective to good use.
Iridium NEXT-7 thankfully brought an end to the understandable but still-painful practice of intentionally expending twice-flown Falcon 9 boosters in the ocean after launch. Thanks to Iridium-7’s new Block 5 booster, B1048, expending the rocket was out of the question, as it likely will be for most Block 5 launches in the future. A combination of several expendable missions and an unfortunate duo of recovery anomalies (a small fire after Koreasat 5A and the Falcon Heavy center core landing failure) led to JRTI sitting on the sidelines since October 2017, as a considerable subset of its critical thruster hardware had to be stripped in order to keep East Coast sister ship Of Course I Still Love You (OCISLY) operational for a handful of attempts in 2018.

Many of the months JRTI spent at berth were thus without the pod thrusters the drone ship needs to keep itself at the proper landing point once at sea. Still, JRTI departed the port with a full complement of four blue thrusters on the evening of July 22 and had a highly successful return-to-action. Sadly, it’s unclear how much SpaceX will need the vessel within just a month or two from today – after the final Iridium launch (NEXT-8) in November or December, perhaps all of SpaceX’s future Vandenberg launches will be lofting lightweight payloads that should allow the company to rely almost entirely on its brand-new rocket landing zone – conveniently colocated barely 1000 feet from the pad – for CA rocket recoveries.

Falcon 9 Block 5 booster (B1048) arrived at Port of Los Angeles on July 27 after landing at sea aboard drone ship JRTI. Photos captured by Pauline arguably show the best details yet seen of the rocket upgrade, ranging from titanium grid fins to extraordinary shots of its sooty-but-still-sorta-shiny Merlin 1D engines.

Myriad others provide an amazing sense of place with SpaceX technicians conducting thorough post-landing checkouts, carefully documenting the booster’s condition, and generally wrenching on a massive, orbital-class rocket that completed a suborbital jaunt to space just days prior.
Of particular note are detailed views of the silky black “highly flame-resistant felt” now covering Falcon 9’s interstage (the top segment), landing legs, octaweb section, and raceways (the black lines traveling up and down the rocket). Compared to beat-up, older Falcon 9s, B1048’s shielded components look barely worse for wear, and it would genuinely be difficult to determine if the rocket had flown before without the telltale soot fingerprint present after every Falcon 9 recovery.

The only mystery that still remains is what exactly Falcon 9 Block 5’s octaweb heat-shielding looks like, reportedly one of the most critical and research-intensive upgrades necessary for true rapid reusability and reliability through many, many flights. Now built largely of titanium bolted to the octaweb, among a number of other extremely heat-tolerant metals and materials and even active water-cooling in spots, the new heat-shield was designed to carry the brunt of the reentry heating Falcon 9 experiences with ease.
Perhaps we’ll get a glimpse of that yet-unseen heat-shield over the next few weeks and months. Many, many more launches to come, so stay tuned!

Tesla gathers Cybercab fleet in Gigafactory Texas
Images and video of the Cybercab fleet were shared by longtime Giga Texas observer Joe Tegtmeyer in posts on social media platform X.
Tesla appears to be assembling a growing number of Cybercabs at Gigafactory Texas as preparations continue for the vehicle’s mass production. Recent footage shared online has shown over 30 Cybercabs being transported by trucks or staged near testing areas at the facility.
The images and video were shared by longtime Giga Texas observer and drone operator Joe Tegtmeyer in posts on social media platform X.
Interestingly enough, Tegtmeyer noted that many of the Cybercabs being loaded onto transport trucks were still equipped with steering wheels. This suggests that the vehicles are likely testing units rather than the final driverless configuration expected for the company’s Robotaxi service.
The vehicles could potentially be headed to testing sites across the United States as Tesla prepares to expand its Robotaxi fleet.
Additional footage captured at Gigafactory Texas also showed the Cybercab’s side and rear camera washer system operating as vehicles were being loaded onto transport trucks.
The growing number of Cybercabs at Giga Texas comes amidst the company’s announcement that the first production Cybercab has been produced at the facility. Full Cybercab production is expected to begin in April.
The vehicle is expected to play a central role in Tesla’s Robotaxi ambitions as the company looks to expand autonomous ride-hailing operations beyond its early deployments using Model Y vehicles.
Tesla has also linked Cybercab production to its proposed Unboxed manufacturing process, which assembles large vehicle modules separately before integrating them. The approach is intended to reduce production costs and accelerate output.
Musk has also noted that the Cybercab’s ramp will likely begin slowly due to the number of new components and manufacturing steps involved. However, he stated that once the process matures, Cybercab production could scale quickly.

Elon Musk’s xAI, creator of Grok and Grokipedia, celebrates its third birthday
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
Elon Musk’s artificial intelligence startup xAI has marked its third anniversary. The update was shared in a post from the xAI Memphis account on social media platform X.
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
As per xAI, it has built three massive data centers in the city, launched a coherent cluster of 330,000 GBs, created over 3,000 jobs, and paid over $30 million in taxes to local communities.
xAI’s Memphis operation has become a key part of the company’s infrastructure as the company works to train and deploy its Grok artificial intelligence models. Elon Musk has been quite optimistic about Grok’s potential, noting in the past that the large language model might have a shot at achieving artificial general intelligence (AGI).
xAI’s Memphis’ crown jewel is its Colossus supercomputer cluster. The project was announced in 2024 and has since become the home of one of the world’s largest AI compute facilities. The first phase of Colossus reached its initial 100,000 GPU operational milestone in just 122 days, or just about four months.
Industry figures such as Nvidia CEO Jensen Huang have praised the facility, noting that projects of similar scale typically take two to four years to complete.
xAI has cited Memphis’ central location, skilled workforce, and industrial infrastructure as key reasons for selecting the city as the home of its AI training operations. The company has also emphasized plans to expand the site further as it scales compute capacity for Grok and future AI models.

Tesla Sweden’s Megapack Supercharger near Arlanda continues to aggravate IF Metall union
The charging site, located in Arlandastad outside Stockholm, appears to be operating despite ongoing union blockade measures tied to Tesla’s labor dispute in the country.
Tesla Sweden’s Megapack-powered Supercharger station near Arlanda Airport has continued to aggravate Swedish labor union IF Metall. The charging site, located in Arlandastad outside Stockholm, appears to be operating despite ongoing union blockade measures tied to Tesla’s labor dispute in the country.
Comments about the site were shared by IF Metall representatives in remarks to Swedish publication CarUp.
The Arlandastad location includes eight Tesla Superchargers powered by a Megapack battery system. Unlike traditional charging stations that rely on direct grid connections, the site uses a large battery installation to store electricity and power the chargers.
According to the Swedish publication, the setup allowed the station to come online despite sympathy measures from Sweden’s electricians’ union, which has attempted to prevent companies from cooperating with Tesla as part of the broader labor conflict.
IF Metall press manager Jesper Pettersson indicated that the union was not aware that the Superchargers had already been connected and activated.
“We do not know the details around this. But it is further proof of how Tesla systematically finds loopholes to circumvent the sympathy measures through active strikebreaking. Every time this happens it gives us reason to sharpen our conflict measures,” Pettersson said.
Union representatives also noted that the Megapack appears to be charged using electrical cables routed through nearby terrain, though the exact power source remains under review.
The Megapack-powered site has then prompted questions from Swedish labor unions about how electricity is being supplied to the system.
IF Metall has submitted a report to Sweden’s Energy Market Inspectorate asking the regulator to review whether the electricity supply arrangement complies with national regulations. The Megapack is reportedly charged using electricity from a local company, though the provider has not been publicly identified.
Peter Lydell, an ombudsman at IF Metall, previously stated that Swedish law limits electricity trading to companies with proper authorization.
“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.
IF Metall and Tesla Sweden’s conflict has been going on for over two years now.
