SpaceX caps major Falcon 9 Block 5 reuse with spectacular Port of LA recovery
SpaceX has completed what might be its most important Falcon 9 reuse yet after successfully launching and recovering booster B1046 for the third time in just six months. Prior to this launch, the company had never before flown a reused Falcon 9 booster more than once.
Making way for a probable fourth launch in the near future, B1046’s Port of Los Angeles return was marked by a stream of spectacular visuals as seasoned SpaceX recovery technicians transferred the booster from drone ship to land, performed initial inspections, and prepared it for transport back to Hawthorne, where it will undergo (hopefully minimal) refurbishment.

Displaying inspiring dedication, Teslarati photographer Pauline Acalin managed to stick with B1046 for a major portion of the six days it spent on the docks, despite a rare spate of rainy and downright stormy days in Los Angeles. Her patience was awarded with a number of beautiful photos documenting nearly every significant aspect of any given Falcon 9 booster recovery, ranging from the lift from drone ship to dockside and the removal of all four titanium grid fins to the rocket’s flip from a vertical to a horizontal orientation ahead of road transport back to SpaceX’s Hawthorne factory.
Above all else, the most noteworthy aspect of Falcon 9 B1046’s third return to port is just how unharmed the rocket appears, at least from an external perspective. The booster has grown a fairly healthy triple coating of kerosene soot from its three reentry and landing burns, thick enough that Falcon 9’s mirror-shiny white skin is barely visible on the lower (RP-1) propellant tank. At this point, it seems that SpaceX has concluded that any possible performance loss from those soot layers are small enough to be negligible.

In an operational sense, SpaceX’s Falcon 9 recovery procedures and the technicians that perform the actual task of recovery seem to be approaching the work with an attitude that fits better in the realm of commercial aviation than in what is perceived as modern rocketry (clean rooms, surgical precision, etc.). Both the procedures and technicians seem to have been refined into what now runs like a well-oiled machine, wrapping up the complex and pathfinding task of recovering a thrice-flown Falcon 9 booster in less than a week from its drone ship landing to Hawthorne arrival.
The condition of B1046 could well make or break the future of the Falcon 9 family, as any significant departure from Block 5’s design intentions could cut the operational lifetime of the ~10 boosters already produced by dozens of fleet-wide flights.

On the other hand, a rapid and relatively painless post-recovery inspection and a general bill of nominal health could – pending customer comfort and SpaceX pricing it right – open the floodgates for the company’s fleet of (optimally) reusable rocket boosters. Even if it turns on that Falcon 9 Block 5 boosters almost invariably demand $10M+ in extensive refurbishment after every launch and can only manage a max of 10 launches before heading to the scrapyard, SpaceX could quite literally become untouchable on the global launch market and remain so for a minimum of 5+ years.

So long as the company can preserve the Falcon family’s impressive and ever-growing heritage of reliability alongside industry-leading reusability, there isn’t a company or country in the world that could beat SpaceX’s business model if it ever came down to a contract competition death-match, so to speak, not for another 5-10 years. It may never come to that, but that capability will – at the bare minimum – give SpaceX a nearly unbeatable upper hand for launching its own global constellation of internet satellites, known as Starlink.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
