SpaceX Mars rocket test site receives first huge rocket propellant storage tank
SpaceX has delivered one of the first undeniably rocketry-related pieces of hardware to its prospective Boca Chica test and launch facility in South Texas, this time in the form of a massive 100,000-gallon liquid oxygen tank now stationed adjacent to the company’s ~600 kW Tesla solar and battery array.
In a statement provided to local paper Valley Morning Star, SpaceX spokesperson Sean Pitt filled in a few of the details and confirmed that the LOX tank had been delivered to Boca Chica as part of an ongoing effort to ready the site for initial testing – and eventually launches – of an unspecified “vehicle”
“Delivery of a new liquid oxygen tank, which will be used to support propellant-loading operations during launch and vehicle tests, represents the latest major piece of launch hardware to arrive at the [South Texas] site for installation.” – SpaceX
The official SpaceX statement may not have explicitly stated that the aforementioned “vehicle” was something other than Falcon 9 or Heavy, but it can be all but guaranteed that the testing and launching described refers to the company’s next-generation Mars rocket, a completely reusable architecture known as BFR.

A slow burn in South Texas
Over the past 6-9 months, SpaceX CEO Elon Musk and President/COO Gwynne Shotwell have repeatedly spoken on the subject of SpaceX’s South Texas ambitions, lending unambiguous credence to the idea that the Boca Chica rocket facility will be almost exclusively dedicated to testing BFR’s first flightworthy spaceship prototypes, beginning with a series of familiar suborbital “hops”.

In the early days of SpaceX’s Falcon 9 reusability program, the company completed several different phases of short flights (“hops”, hence the Grasshopper label) of a development version of a Falcon 9 booster, ranging from purely vertical jaunts just above the pad to 1000+ meter cross-range maneuvers, tests that ultimately culminated in SpaceX’s extraordinarily reliable Falcon 9 and Heavy booster recovery capabilities. Something similar – albeit somewhat more ambitious – is planned for BFR, starting with a prototype of the upper stage (spaceship). Musk described these plans in more detail in an October 2017 Reddit AMA:
Will we see BFS hops or smaller test vehicles similar to Grasshopper/F9R-Dev?
A (Elon): A lot. Will be starting with a full-scale Ship doing short hops of a few hundred kilometers altitude and lateral distance. Those are fairly easy on the vehicle, as no heat shield is needed, we can have a large amount of reserve propellant and don’t need the high area ratio, deep space Raptor engines.
Speaking a bit less than five months later after the stunningly successful debut of Falcon Heavy, Musk expanded further on the BFR test program, reiterating that spaceship hop testing would “most likely … happen at our Brownsville [South Texas] location,” perhaps as early as 2019.
“We’ll do flights of increasing complexity. We really want to test the heat shield material… like fly out, turn around, accelerate back real hard, and come in hot to test the heat shield.”

Musk also noted that he expected the first full-up orbital launch with both the Booster (BFB) and Spaceship (BFS) could happen as soon as 2021 or 2022. Shotwell, on the other hand, stated in early 2018 and again more recently that she believed BFR could begin its first orbital test missions as early as 2020, an extraordinarily rare moment where the typically pragmatic executive appeared to be more confident than Musk, often lambasted for his reliably over-optimistic timelines. About a month later, Musk’s comments were much more closely aligned with Shotwell’s BFR timeline estimates, and he enthusiastically said that that spaceship hop tests would likely begin within the first half of 2019.
The unambiguous arrival of a rocket propellant storage tank – confirmed officially by SpaceX – strongly suggests that activity is about to seriously pick up speed in Boca Chica for the first time in a year and a half, paving the way for full-scale hop tests of the first Mars spaceship prototype perhaps less than a year from today.

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.
