SpaceX’s first flight-proven Starship could fly again, says Elon Musk
Elon Musk says that SpaceX wants to reuse its first flight-proven Starship prototype, although the rocket’s second hop might come after the debut of a totally different ship.
On August 4th, for the first time ever, a full-scale Starship prototype measuring some 9m (30 ft) wide and 30m (~100 ft) tall lifted off from SpaceX’s Boca Chica, Texas test facilities. Just three weeks shy of the first anniversary of Starhopper’s last flight test, Starship serial number 5 (SN5) essentially repeated the stubby prototype’s 150m (~500 ft) hop before (relatively) gently landing on an adjacent concrete pad.
Over the last several days, SpaceX has gradually been working through the unprecedented task of inspecting, safing, and relocating a flight-proven Starship. At the same time, the company has to check out the fixed launch mount structured that supported the test flight and provided Starship with power, propellant, and wired communications. As teams work to get both ship and mount ready for round two, CEO Elon Musk has taken to Twitter to discuss some of SpaceX’s nearer-term goals and plans for Starship testing – including SN5’s role in them.
Starship SN5’s hop debut was a spectacular success for SpaceX, verifying that steel and radically simple and manufacturing techniques can quickly build a cheap pressure vessel capable of controlled flight. The flight also reaffirmed that the next-generation Raptor engine is capable of operating uninterrupted for at least ~50 seconds, although Starhopper’s 150m hop proved the same thing some 20 engine prototypes and 13 months prior.
Still, while it unequivocally proved that SpaceX is on the right track, both the lead-up to Starship SN5’s hop and the hop itself hint that a few kinks will still need to be worked out. Notably, during SN5’s hop, part of Raptor engine SN27 appeared to catch fire at some point after ignition, producing substantial flames that lasted for at least 10 seconds. For any rocket engine, an onboard fire is always a possibility, but most engines are either designed to tolerate the inhospitable environment they create or heavily insulated from it.
Festooned with sensitive wires and harnesses, Raptor prototypes are likely not meant to experience an extended onboard fire and remain functional, but SN27 nevertheless did just that. At a minimum, Starship SN5 thus likely needs a new Raptor engine before it can begin to prepare for a second hop.
The prototype will also assuredly need several new landing legs after destroying at least two during its launch and landing debut. It’s worth pointing out that the leg damage visible above is almost certainly the result of an intentional design choice, ensuring that landings slightly rougher than expected transfer most of their stress into Starship’s legs instead of its hull. Given just how simple they appear, the current leg design likely makes them effectively disposable, allowing SpaceX to focus its effort on unsolved problems as a more refined and reusable leg design comes to fruition.
Aside from confirming that SpaceX at least intends to reuse Starship SN5 on future hops, Musk revealed that he wants to refine the launch procedure until the company is able to easily perform multiple Starship hops per day. This suggests that the next one or several months could be chock full of Starship hop attempts. Musk also noted that Starship SN6 – a prototype built along SN5 and effectively completed weeks ago – would likely attempt its first flight before SN5 hops a second time. SpaceX began stacking the upgraded Starship SN8 prototype just a few days ago, raising the question of whether Starship SN6 would be made redundant before it could even left the factory.
Thankfully, it seems that the ship will instead be able to work alongside its sister (SN5) to help SpaceX simplify and expedite Starship test and launch operations. As of now, it’s unclear when SpaceX intends to restart Starship testing, but Musk’s comments point towards the next test happening far sooner than later.

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.
