Elon Musk gifts SpaceX Starship angel investor a piece of Starhopper history
According to photos posted by the Japanese investor, SpaceX CEO Elon Musk has gifted Yusaku Maezawa a significant piece of Starhopper history, a celebration of the rocket prototype’s successful flight tests and a gesture of thanks for Maezawa’s substantial support.
Back in September 2018, Musk revealed that Japanese billionaire Yusaku Maezawa had become the first true customer for SpaceX’s next-generation Starship launch vehicle. In fact, Maezawa announced DearMoon, a private spaceflight venture with the aim of sending a dozen or so artists on the first commercial crewed mission around the Moon – all for free.
In a bid to assist Starship development and simultaneously secure rights to the massive spacecraft’s first crewed lunar launch, Maezawa committed what is believed to be several hundred million dollars of his personal fortune to SpaceX. In turn, the Japanese billionaire plans to select roughly a dozen artists from around the world and offering them a free ticket aboard Starship’s first crewed circumlunar launch, traveling once around the Moon and returning to Earth after 10 or so days in space.
Perhaps just a few weeks after the DearMoon announcement and Starship event, SpaceX CEO Elon Musk decided to radically change the Starship program, entirely replacing the vehicle’s main structural material of choice – carbon fiber composites – with stainless steel. The primary goal was to dramatically lower the cost of development and vehicle production and speed things up, but Musk quickly realized that steel could unintuitively be better than carbon fiber in almost every way.
After Musk’s decision, SpaceX pivoted from carbon fiber to steel at a spectacular pace. Barely six months after the design change, a SpaceX team had built up its Boca Chica, Texas facilities from almost nothing, begun to build full-scale steel hardware, and nearly completed the first low-fidelity prototype, known as Starhopper. That vehicle began propellant loading and wet dress rehearsal testing in early-April 2019 and although technical difficulties with its next-generation Raptor engines caused several months of delays, it moved into its first flight test campaign three months later.
Starhopper’s first untethered flight was completed successfully on July 25th, reaching an apogee of ~18 meters (60 ft). A little over one month later, Starhopper lifted off for the second time on a significantly more ambitious ~150m (500 ft) flight test, completed successfully after about 60 seconds in flight. That second test would be Starhopper’s last and SpaceX quickly turned its focus to completing the first full-scale, full-fidelity Starship prototypes, known as Mk1 (TX) and Mk2 (FL).
Throughout this process, Yusaku Maezawa has followed along with SpaceX. Rather than a simple lump-sum agreement, the billionaire’s contract with SpaceX is structured much more specifically, essentially allowing the company to unlock additional funding after certain milestones – like Starhopper’s flight tests – are completed. The arrangement is more of a carrot on a stick than something dead-serious – Maezawa is probably not going to completely withhold funding if SpaceX slightly misses exact targets or suffers anomalies during a complex launch vehicle development program.


In order to complete its two flight tests, Starhopper needed some kind of attitude control system (ACS) to remain stable and SpaceX chose a decidedly SpaceX-y solution, simply bolting on flight-proven Falcon 9 thruster pods. Those pods use high-pressure nitrogen to change Falcon 9’s attitude, correctly point the rocket, and settle its propellant while the rocket is in a vacuum (or freefall). They can also provided limited control authority in atmosphere, which is what SpaceX used them for on Starhopper.


As a gesture of gratitude for Maezawa’s extremely helpful financial support, SpaceX gifted him an entire Starhopper thruster pod. SpaceX often does similar things for major flight milestones, creating commemorative gifts out of retired hardware (rocket tanks, engine bells, grid fins, parachute threads, etc.) that employees are able to purchase. An entire thruster pod is at least a few orders of magnitude above that, a sign of just how grateful SpaceX is to Maezawa.
Of note, in his tweet showing off the thruster pod, Maezawa suggested that “Starship development is going better than expected”, indicating that he may “need to invite a passenger soon” for his planned circumlunar voyage around the Moon. Prior to Starship’s radical shift from carbon fiber to steel, that mission was scheduled no earlier than 2023. In recent months, SpaceX executives have made it clear that they are now targeting Starship Moon landings by 2022, suggesting that the first circumlunar missions – a far easier task than landing – could be possible even sooner than that.

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.
