SpaceX Starship flight debut could happen this week, says Elon Musk
SpaceX CEO Elon Musk says that Starship’s full-scale flight debut could happen as early as this week if a suite of tests planned over the next few days goes according to plan.
The SpaceX leader also revealed a bit about the company’s plan to create its own custom steel alloy to build the best Starships possible – the first of which is already under construction. Beginning with Starship SN8, parts of which have already been spotted in work at SpaceX’s Boca Chica, Texas rocket factory, all future ships are expected to be built out of steel different than the 301 alloy used for all prior ships.
Of course, Starship SN8 is likely 2-4 weeks at best away from being ready for integrated testing. Instead, Starship SN5 is currently occupying SpaceX’s adjacent test stand and launch pad as teams work to prepare the rocket for several tests – potentially culminating in the first flight of a full-scale Starship.
For more than two weeks, SpaceX has been slowly preparing Starship SN5 for its first wet dress rehearsals and Raptor engine static fires. When a ground systems leak lead to a massive fuel-air explosion and Starship SN4’s destruction, it severely damaged the pad and required the construction of an entirely new launch mount.
Based on photos of the gradual rebuild taken by Boca Chica Village resident and photographer Mary (bocachicagal), SpaceX has visibly taken the opportunity to implement some significant changes (possibly upgrades) to the pad’s ground support equipment (GSE). Notably, the company has already installed a system meant to reclaim waste methane that would otherwise have to be burned at a flare stack, instead re-liquefying the gas a returning it to propellant storage tanks.
It’s unclear if SpaceX is attempting to onboard that new system as part of Starship SN5’s first major fueling tests, but the flare stack has not been active for weeks and the finicky nature of methane reclamation would certainly explain some of the 10+ days of delays.
On July 17th, after many day-by-day delays, SpaceX began Starship SN5’s first fueling test. The rocket appeared to be briefly pressurized with ambient-temperature gas (possibly methane and oxygen) but the test was quickly aborted. Another attempt on July 20th was also aborted after several hours with no frost (indicative of propellant loading). Finally, a third attempt on July 21st was canceled before it began, although a roadblock was briefly set up prior to the abort. Shortly after the abort, SpaceX published plans for another attempt at Starship SN5’s first WDR and static fire test on July 22nd with backup windows (8am-5pm CDT, UTC-5) on the 23rd and 24th.
First reported by NASASpaceflight.com, Elon Musk’s comment confirms their sourced information that Starship SN5’s flight debut could follow just a few days after a successful WDR and static fire. Given the sheer number of delays SN5’s test campaign has suffered, that’s far from guaranteed, but the ship certainly still has a shot at a hop test this weekend if things go perfectly over the next several days. Stay tuned for updates later today or tomorrow.

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.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
Recent sightings on public roads and growing fleet activity at Giga Texas signal Tesla’s accelerating push toward the Cybercab’s commercial launch.
Tesla Cybercab is being spotted with increasing frequency both on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production.
A total of 25 Cybercab units were recently observed across three separate locations at Giga Texas by drone observer Joe Tegtmeyer — with 14 metallic gold units parked in a tight formation outside the factory exit, nine more at the crash testing facility undergoing structural and safety validations, and two additional units at the west end-of-line area for final checks.
The activity on public roads is just as telling. The Cybercab was spotted testing on public roads for the first time last October, near Tesla’s Engineering Headquarters in Los Altos, California, marking a significant development in the vehicle’s progression toward commercial readiness. As expected at that early stage, a safety driver was present in the seat.
Since then, sightings have only become more frequent. Community observers on X have posted fresh footage of Cybercabs navigating public streets in Silicon Valley, with each new clip adding to a growing body of evidence that Tesla’s validation efforts are well underway. The production backdrop supports the momentum. Tesla’s production line at Giga Texas moved into a higher volume early in March, representing what observers are calling the largest single-day grouping of Cybercabs seen to date.

Tesla ramps Cybercab test manufacturing ahead of mass production
Musk has also stated that Tesla is aiming for at least 2 million Cybercab units per year across more than one factory, with a potential ceiling of 4 million annually.
With testing activity on public roads accelerating and factory output visibly increasing week over week, the coming months at Giga Texas are set to be pivotal in determining how quickly Tesla can bring the Cybercab from validation to volume.
