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’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.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
Recent sightings on public roads and growing fleet activity at Giga Texas signal Tesla’s accelerating push toward the Cybercab’s commercial launch.
Tesla Cybercab is being spotted with increasing frequency both on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production.
A total of 25 Cybercab units were recently observed across three separate locations at Giga Texas by drone observer Joe Tegtmeyer — with 14 metallic gold units parked in a tight formation outside the factory exit, nine more at the crash testing facility undergoing structural and safety validations, and two additional units at the west end-of-line area for final checks.
The activity on public roads is just as telling. The Cybercab was spotted testing on public roads for the first time last October, near Tesla’s Engineering Headquarters in Los Altos, California, marking a significant development in the vehicle’s progression toward commercial readiness. As expected at that early stage, a safety driver was present in the seat.
Since then, sightings have only become more frequent. Community observers on X have posted fresh footage of Cybercabs navigating public streets in Silicon Valley, with each new clip adding to a growing body of evidence that Tesla’s validation efforts are well underway. The production backdrop supports the momentum. Tesla’s production line at Giga Texas moved into a higher volume early in March, representing what observers are calling the largest single-day grouping of Cybercabs seen to date.

Tesla ramps Cybercab test manufacturing ahead of mass production
Musk has also stated that Tesla is aiming for at least 2 million Cybercab units per year across more than one factory, with a potential ceiling of 4 million annually.
With testing activity on public roads accelerating and factory output visibly increasing week over week, the coming months at Giga Texas are set to be pivotal in determining how quickly Tesla can bring the Cybercab from validation to volume.
