SpaceX scraps Florida Starship Mk2 prototype
SpaceX has scrapped the lone Starship prototype built in Florida in 2019, surprising very few.
Beginning a few months after work began on Starship Mk1 at SpaceX’s South Texas production facilities, a separate team in Cocoa, Florida was tasked with building a similar Starship Mk2 prototype. Not much is known about Mk2 relative to its much more publicized sibling but unofficial photos and videos taken over the course of 2019 suggested that SpaceX had effectively completed most of Starship Mk2 by the end of last year. However, built dozens of miles and several waterways away from a practical test facility, actually testing a Starship prototype assembled at SpaceX’s Cocoa facilities was always going to be an uphill battle.
To warrant the cost and effort that would be required to transport something as large as a vertical Starship from Cocoa, Florida to Cape Canaveral, Mk2 would have to be able offer something invaluable during testing. Now eight months after Starship Mk1 was destroyed during one of its first real tests, that was sadly not the case and SpaceX has chosen the simplest route forward – scrapping Mk2 where it sits.
In November 2019, SpaceX installed Starship Mk1 on a test stand in Boca Chica, Texas and began a series of tests. The ship passed an initial ambient temperature pressure test on the 18th but failed spectacularly during its first cryogenic proof test, said by SpaceX to have “pressurize[d] systems to the max.” Excluding Starhopper, Starship Mk1 was about as rough of a prototype as SpaceX could have feasibly built and the fact that it survived any length of time under cryogenic loads and pressures was fairly impressive.
Welded together almost entirely out in elements on the South Texas Gulf coast, the total success of Starship Mk1 (and its similar Mk2 sibling) would have flown in the face of almost every single tenet of modern aerospace production. As noted in a Teslarati article describing the Starship’s demise, the Mk1 production apparatus left plenty of room for improvement.
“[Videos of the failure implicated] the weld connecting the LOX dome to the cylindrical body of Starship’s LOX tank, pointing to a bad weld joint as the likeliest source of the failure. Although that hardware failure is unfortunate, Mk1’s loss will hopefully guide improvements in Starship’s design and manufacturing procedures.”

That is precisely what SpaceX did – and was likely already doing – in response to Mk1’s failure. Just two months later, SpaceX successfully tested a steel Starship tank built in upgraded facilities with upgraded methods and reached pressures of 7.1 bar (~103 psi) before failing – likely a 50% improvement or better relative to Mk1. A second tank completed weeks later in late January 2020 reached 7.5 bar, sprung a leak, was repaired, and ultimately soared to 8.5 bar (~125 psi) before failing. Per CEO Elon Musk, that would technically be enough for a Starship to launch humans into orbit with an industry-standard ~40% safety factor.
Finally, SpaceX recently proved that a full-scale, two-tank Starship prototype built with the same methods and facilities as those test tanks could achieve the same results, completing a ~7.5 bar (~110 psi) cryogenic proof test with Starship SN4 on May 10th.
Long story short, the methods SpaceX used to build Starship Mk1 and Mk2 were already proven redundant more than six months ago and buried even deeper in May 2020. Aside from serving as a museum piece, Starship Mk2’s fate was sealed – the only real question was how and when it would be scrapped. For now, SpaceX’s Starship program will be almost exclusively stationed in South Texas, where it appears to be in good hands. Starship SN5 is currently expected to attempt its first wet dress rehearsal (WDR) and static fire tests no earlier than July 17th (today) at 8 am CDT (13:00 UTC).

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.
