SpaceX Starship launch pad upgraded as Elon Musk reveals rocket production milestone
SpaceX has begun to upgrade its South Texas Starship launch pad in anticipation of the completion of the next full-scale rocket prototype, photos of which CEO Elon Musk revealed just hours ago.
Working in parallel with efforts to repair damage caused by Starship serial number 1’s (SN1) violent February 28th test failure, SpaceX has managed to build, complete, and test an entirely separate ‘test tank’ and complete fabrication of a second full-scale Starship in a handful of weeks. Flexing the growing capabilities of the impressive Boca Chica, Texas Starship factory SpaceX has sprung up in just three months, the company is working around the clock to build not just one – but several – Starship prototypes simultaneously.
A successful March 9th tank test designed to prove a new thrust structure design managed to do just that less than two weeks after the same faulty part brought about Starship SN1’s demise. In the two weeks since that its test completion, SpaceX has been busy welding, stacking, welding, and stacking several separate sections of the next Starship prototype, known as SN3. Potentially a matter of days away from structural completion, focus has recently shifted to the launch pad the ship will be tested at. In the last few days, SpaceX technicians have begun to install a bizarre, new structural element on the mount Starship SN3 will be secured on top of, hinting at the goals of the rocket’s first test campaign.
Squeezing in alongside efforts to repair the propellant lines that run into the launch mount, upgrades began on March 24th as a SpaceX team worked to install what looked like an incredibly sturdy tripod (with four ‘legs’, of course). Thanks to familiar testing done with SpaceX’s most recent Starship tank prototype, the purpose of the launch mount’s newest appendage quickly became clear.
During the Starship SN2 tank’s thrust structure (‘thrust puck’, per Elon Musk) test campaign, SpaceX debuted the concurrent use of a beefy hydraulic jack to simulate the forces a Raptor engine static might produce. Capable of producing upwards of 200 metric tons (440,000 lbf) of thrust at full power, SpaceX will likely begin Starship static fire tests with a single Raptor engine. As soon as a Starship prototype completes one or several single-engine test fires, the plan is to install three sea level-optimized Raptor engines and repeat static fire tests.
Before that triple-engine static fire milestone, a first for the cutting-edge Raptor engine, SpaceX needs to verify that Starship’s thrust structure can stand up to the ~600 tons (~1.3M lbf) of force it will be subjected to during such a test. Sitting on a much smaller stand, Starship SN2 used a single hydraulic jack and temporary stand to simulate a single engine’s thrust. Starship SN3, sitting much higher above the ground, will need three jacks to simulate three Raptors.
As such, it looks likely that Starship SN3’s first cryogenic tank proof test – filling the vehicle with inert liquid nitrogen – will coincide with a second dedicated stress test of a Starship thrust structure, hopefully proving itself capable of surviving the force of three Raptor engines at full thrust. While orbital-class Starships will need three more vacuum-optimized Raptor engines, three sea-level engines are all SpaceX needs to begin flight tests with suborbital prototypes.
Based on an unofficial analysis of existing photos, it appears that every single major structural piece of Starship SN3 – excluding legs and fins – is nearing completion, even including the ship’s shiny nosecone. Likely to head to the launch pad for its first tests as soon as the tank section alone has been completed, just one stacking event remains before said tank section reaches its full height. Right now, both of those parts have been moved to a dedicated Vehicle/Vertical Assembly Building (VAB) and are probably no more than a day or two away from being joined*. Perhaps just a day or two after that milestone, SpaceX will likely transport the massive rocket to the launch pad to begin preparing for its first proof tests.
*Around 3am local time, SpaceX technicians stacked Starship SN3’s two main segments, completing its tank and engine section.

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.
