SpaceX’s next Falcon Heavy two-thirds done as side booster #2 leaves factory
First posted to a SpaceX-focused Facebook group by member Eric Schmidt, Falcon Heavy Flight 2’s second side booster (of two) was spotted eastbound in Arizona on December 3rd, partway through a journey from SpaceX’s Hawthorne, CA factory to its McGregor, TX testing facilities.
This is the second (known) Falcon Heavy-related booster spotted in less than a month and an incontrovertible sign that the company’s second-ever Falcon Heavy launch is perhaps just a handful of months away, with both side boosters now likely to be present in Florida by January 2019 barring unforeseen developments.
Look who was waving at passing planes over McGregor today!

This second booster appearance follows on the heels of the first Falcon Heavy booster spotting on November 9-10, confirming that – at a minimum – two of the next rocket’s three first stage boosters have finish production and are now focused on completing their separate hot-fire acceptance tests at McGregor. Owing to the ironic fact that the center core – dramatically more complex than its pointy-nosed side core brethren – is far harder to discern while in transport, it’s even possible that the second side core spotting is actually the third new Falcon Heavy booster to depart SpaceX’s factory. The above booster was apparently the second SpaceX first stage to make its way east through Arizona in the week prior to its arrival, so that may well be the case.

While Falcon Heavy side boosters do sport easily recognizable nosecones, they apparently are able to be modified from a Falcon 9 booster to a side booster with no more than a week or two’s work. On the other hand, the rocket’s center booster is dramatically more complex and requires an entirely new custom rocket be built from scratch thanks to the extreme loads it must survive when the two side boosters channel all of their thrust directly into the center core during launch.
However, until the arm-like mechanisms that connect the center stage to its two side boosters are attached, it’s extremely difficult to discern between a normal Falcon 9 booster and a Falcon Heavy center stage. Until a center core is more or less unwrapped and showing off its octaweb or unusual bumps around the interstage, its identity is likely to remain a secret. In the past three months, no fewer than four Falcon boosters arrived at Cape Canaveral, while only one (or maybe two) of them have launched in the time since their arrival.

Given that both side boosters have traveled from California to McGregor, it’s almost certain that Falcon Heavy will fly for the second time with all-new Block 5 hardware, including all three boosters and the upper stage. Most importantly, a Block 5 version of the non-interchangeable center stage should ultimately be able to launch multiple times with zero or minimal refurbishment and repairs, potentially making Falcon Heavy for more viable from a production and internal cost perspective. For a rocket that may only ever launch twice per year, one or two custom center cores could be all that is needed over the vehicle’s operational lifetime, save for any potential launch contract that requires expendable performance.
Ultimately, this second Falcon Heavy booster spotting in less than four weeks is a thrilling sign that SpaceX is pushing extremely hard to have the rocket’s next iteration integrated and ready to launch as soon as possible, perhaps as early as Q1 2019. As its two side boosters begin to arrive in Florida, we should start to have a better idea of when exactly the massive rocket’s second launch might be.

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.
