SpaceX’s first flight-proven Starship takes another step towards reuse
Nine days after becoming the first full-size prototype to survive a high-altitude launch and landing, SpaceX has installed Starship SN15 at the second of two identical launch mounts to prepare for potential reuse.
On May 5th, after a week or two of several minor delays, Starship SN15 – the fifth full-size prototype of its kind – lifted off from SpaceX’s Boca Chica, Texas launch pad under the thrust of three Raptor engines. Like all four of its predecessors, the 50-meter-tall (165 ft) steel rocket easily ascended to an apogee greater than 10 km (6.2 mi), shutting down one Raptor every ~90 seconds to its keep velocity low. When the final engine cut off, SN15 arced over onto its belly and free-fell to around half a kilometer above the ground, using four hollow steel ‘flaps’ to control its orientation like a skydiver’s limbs.
The most radical maneuver came around six minutes after liftoff when the sideways Starship reignited two or three of its Raptors, aggressively flipped into a nose-up position, deployed six stubby landing legs, and gently touched down a few hundred feet east of the stand it took off from.
Despite a fairly large fire that burned for several minutes after touchdown, SpaceX ultimately found itself – for the first time ever – with a full-size Starship prototype that survived its inaugural ~10-km launch and landing. A careful process of safing and securing then followed as operators commanded (or monitored) SN15 to disarm explosive flight termination system (FTS) charges, vent any remaining propellant, and eventually depressurize its fuel and oxygen tanks.
Unlike Starhopper, SN5, and SN6 – which also survived flights – SpaceX was apparently able to safe SN15 without any real issues and recovery teams were able to approach the rocket within a few hours of landing instead of the 12-24+ hours that were normal prior. SpaceX also debuted a sort of supersized version of the ‘Octagrabber’ robots that remotely secure Falcon boosters after drone ship landings, allowing the recovery team to secure Starship SN15 to a stable platform and transporter without a crane.
No longer at risk of toppling over, Starship SN15 then… sat where it landed. Less than two days after touchdown, CEO Elon Musk unexpectedly revealed that SpaceX “might try to refly SN15 soon,” indicating that initial post-flight inspections had revealed that the first flight-proven three-engine Starship was in excellent condition. SN15 would ultimately spend another four days (six total) sitting on a transporter at the landing zone. On May 11th, SpaceX rolled Starship SN15 from its landing spot to “Pad B” – the second of two identical suborbital launch mounts.
Perhaps due to stormy weather and high wind gusts in the area, SN15 once again sat still – this time for another three days. Ultimately, the Starship prototype was rapidly lifted onto Pad B’s launch mount, secured, and detached from the crane in a matter of hours of May 14th – possibly the smoothest pad installation yet. In the two days since then, SpaceX has begun more in-depth inspections that will ultimately determine whether the first flight-proven Starship is truly fit for a second launch.
That process likely wont take more than a few days and even if SN15 isn’t deemed (re)flightworthy, there’s still a very good chance SpaceX will put the Starship through some kind of test(s) before it’s retired. Stay tuned for more details likely to come this week.

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.
