SpaceX fits Starship prototype with tank bulkheads as hop test pad progresses
SpaceX workers have begun installing fuel and oxidizer tank bulkheads inside the first BFS/Starship prototype at the same time as the vehicle’s nearby ‘launch’ facility continues to sprout important infrastructure and slowly morph from a giant pile of dirt into something capable of supporting rocket hop tests.
Several observable characteristics of this project still do not immediately make sense but whatever the direction SpaceX is moving in, engineers and technicians are working around the clock to ensure that progress is steady.

Moreso than any other single part, the most confusing aspect of Starhopper has to be the apparent condition of its steel tank domes, distinctly covered with a patina of impurities like rust, dirt, dust, and grime. For a water tower or other miscellaneous storage tank, this would be completely acceptable. For aerospace-grade propellant tanks that will have to safely store dozens or even hundreds of tons of supercool liquid methane and oxygen to feed ultra-high-performance Raptor engines, the purity of ingested propellant and thus the cleanliness of the tanks holding it is going to be of paramount importance.
To use an example that applies to the rockets SpaceX currently flies, Falcon 9’s first and second stages are almost always drained and cleaned before and after their first static fire tests in McGregor, Texas to ensure that no unintended debris is ingested by Merlin turbopumps. This is necessary because Falcon rockets are currently built in an extremely large hangar that simply cannot feasibly be kept to cleanroom conditions, while SpaceX’s garment requirements are less strict than some old-guard aerospace companies, typically letting workers wear normal clothes (albeit with hairnets/beardnets) while working inside Falcon 9 tanks and structures. The improved work conditions and worker comfort comes at the cost of frequent tank cleaning.

While SpaceX clearly has a great deal of experience with nontraditional methods of rocket production, the Hawthorne assembly line might be the cleanest cleanroom on Earth compared to Starhopper’s rusty tank domes and fully-outdoors assembly. Even odder is the apparent fact that SpaceX is actually installing (and maybe even welding) those tank domes without any cleaning at all, indicating that they either look far worse than they actually are, are not a real problem for Raptor or cryogenic propellant tanks, or will be scoured only after installation. Regardless, SpaceX is keeping close followers and those familiar with aerospace on the tips of their toes as Starhopper continues to be worked on.
(Launch) pad progress
Roughly one mile to the east of Starhopper’s assembly roost, SpaceX employees and contractors have been working to complete earthmoving and start outfitting a prospective Starhopper prototype launch pad with a stable concrete base and all the infrastructure needed to support a complex rocket and its propellant, electricity, and heat-resistant surface needs. However, despite recent statements from executives like CEO Elon Musk and COO/President Gwynne Shotwell, the ‘facility’ appears to be many, many months away from anything reminiscent of an actual launch pad like the three SpaceX currently operates in California and Florida.

Instead, it seems that the first BFR-related launch facility will be more of a Spartan, minimalist slab of concrete, a healthy berm, and a handful of propellant tanks and heat exchangers, much like the ‘pad’ that supported Falcon 9’s Grasshopper and F9R hoppers. Over the last few days, the pad construction crew has installed the first of those propellant tanks and heat exchangers and continue to refine the overall layout of the site, still primarily made of compacted dirt. Given the potential simplicity of a Grasshopper-style launch and landing pad, the facility could be anywhere from a few weeks to a few months away from completion.

SpaceX wants to catch Starship for launch 14, Elon Musk says
Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

— Elon Musk (@elonmusk) July 25, 2026
A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.
Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of Mexico.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.

Tesla to open source Model S and Model X designs and software
In a move echoing its earlier commitment to open innovation, Tesla CEO Elon Musk announced recently that the company plans to make the design and software of its Model S and Model X fully open source.
This follows the same approach Tesla took with its original Roadster, releasing all available design, engineering, and diagnostic materials in November 2023 so that “whatever we have, you now have.”
Just as Tesla made the original Roadster design & software open source, we plan to do the same with Model S & X
— Elon Musk (@elonmusk) July 24, 2026
The Model S, introduced in 2012, was Tesla’s first mass-produced vehicle and a groundbreaking luxury electric sedan. It offered impressive range, rapid acceleration, and over-the-air software updates that redefined expectations for electric cars.
The Model X, launched in 2015, built on that foundation as a high-performance electric SUV notable for its distinctive falcon-wing doors, spacious interior, and advanced safety features. Both models served as flagships that helped establish Tesla as a leader in the EV industry and popularized long-range battery-electric vehicles.
Production of the Model S and Model X was wound down earlier in 2026, with manufacturing ending in the second quarter. Tesla redirected the Fremont factory space previously used for these vehicles toward higher-priority projects, including Optimus humanoid robots and the Cybercab autonomous vehicle.
By the time of Musk’s open-source announcement, custom orders had closed and only remaining inventory was available.
Open-sourcing the designs and software offers several clear advantages. Owners of these aging but still capable vehicles gain better access to technical documentation, diagnostic tools, and software resources, making independent repairs and modifications easier and more affordable.
Independent repair shops and third-party specialists can support the large existing fleet without relying solely on Tesla’s service network. Enthusiasts and engineers can study real-world implementations of Tesla’s battery, powertrain, and software systems, potentially accelerating broader industry progress in electric mobility.
The step aligns with Tesla’s 2014 patent pledge and its overall mission to advance sustainable transport by sharing hard-won knowledge rather than locking it behind proprietary walls.
By releasing these materials now that the models have left production, Tesla ensures continued support for its early adopters while freeing internal resources for future technologies. The open-source release of the original Roadster already enabled simulations, community projects, and deeper technical understanding.
Extending that practice to the Model S and Model X should deliver similar benefits on a larger scale, helping keep these influential vehicles relevant and repairable for years to come

Tesla flexes incredible Robotaxi metric that skeptics will hate
Tesla flexed one incredible Robotaxi metric during the Q2 Earnings Call that skeptics have to hate to hear. The company’s platform has already driven more than 380,000 miles of unsupervised ride-hailing across several states with no notable incidents.
During the company’s Q2 Earnings Call on Wednesday, Vice President of AI, Ashok Elluswamy, said:
“First of all, I’d like to state that the Robotaxi program has been operating extremely well. Especially in terms of safety, the program has had an impeccable safety record. We have driven more than 380,000 miles of unsupervised Robotaxi, now across six cities in two different states. We have had zero notable incidents. Any reports have been of other actors impacting us when we were stationary. I like to emphasize how safe the operation has been so far. Zero notable incidents over 380,000 miles.”
Elluswamy’s claim over Robotaxi miles is a significant milestone for Tesla in the grand scheme, especially considering this is a sizeable number of miles without any incident.

— Tesla (@Tesla) July 22, 2026
Tesla’s self-driving approach is much different than that of other companies. Tesla has maintained that vision is the only thing needed to have a solid and effective self-driving suite. Many self-driving companies utilize things like LiDAR, sensors, and other elements to improve performance, but Elluswamy sent a jab at those who believe it’s needed.
“Historically, the so-called experts have always claimed that you need LiDARs, radars, HD maps, and the entire kitchen sink to drive safely. Here we show that such is not true. You can have safe, comfortable, and affordable autonomy with just cameras. This record should be a huge validation of Tesla’s entire AI approach.”
The feat of accumulating this many miles without any driver behind the wheel is impressive. The thing is, Tesla is also doing this across several different locations, with varying traffic rules, pedestrian levels, weather patterns, and other important factors.
While Tesla is not ready to roll out an unsupervised platform completely, it is a slow but steady indication that the company is well on its way to figuring things out.
The company’s attitude toward expansion is slow, safe, and controlled, and despite this huge milestone, it will still be some time until we see Tesla truly unleash unsupervised rides more aggressively.
