SpaceX workers have been spotted repairing the company’s newest Starship prototype in the days after the rocket’s first partial test.

Starship S24 was transported to SpaceX’s Starbase, Texas orbital launch site (OLS) on May 26th after about two and a half months of assembly, marking the first time SpaceX transported a new Starship prototype to a test stand since August 2021. Less than 24 hours later, after attaching Ship 24 to a new test bay located beside the actual ‘orbital launch mount,’ the Starship prototype came to life and began its first proof test.

Unfortunately, while it’s impossible to judge with certainty without official confirmation, Ship 24 either failed to complete that test or did not make it through unscathed.

Known as an ambient or pneumatic proof test, the main goal is to pressurize a Starship or Super Heavy prototype with nonflammable, ambient-temperature nitrogen gas to ensure that the rocket and all its plumbing are structurally sound and working as expected. A successful test would likely require a prototype to reach and sustain flight pressures – up to 8.5 bar (~125 psi) as of 2020 – without exhibiting any significant leaks or problems.

For a while, Ship 24’s first ambient proof test went about as expected, with lots of small vents from its main liquid oxygen (LOx) and methane (LCH4) tanks. No activity was visible at the ship’s nose, where vents and plumbing attach to a pair of small landing (header) propellant tanks. Ship 24 is the first Starship with an upgraded version of those tanks after SpaceX decided to remove the methane header tank from the main methane tank and relocate it directly under the oxygen header tank, which takes up the tip of Starship’s nose.

After an hour or two of testing, a muffled bursting noise different from previous vents was heard, followed by a quieter ‘whoosh’ more akin to a long vent. At the same time as the loud noise was heard, a good dozen or so of S24’s thousands of heat shield tiles were knocked off the section of the hull between the Starship’s main tanks and nose cone. SpaceX depressurized Ship 24 soon after and within a few hours, workers could be seen extracting a pipe from the ship that appeared to have been bent almost in half.

Three days later, workers were spotted guiding apparent replacement pipes into Ship 24. Altogether, it appears that some small section of Ship 24’s internal piping failed catastrophically after it was pressurized during the vehicle’s first pneumatic proof test, knocking tiles loose and possibly damaging other adjacent plumbing. Given the location of that piping inside Ship 24’s nose section, there’s a nonzero chance that the failure occurred when SpaceX attempted to pressurize the Starship’s new header tanks, which would have started by pressurizing the propellant and gas lines leading to them. That would explain the first muffled burst, the subsequent venting sound that slowly faded to nothing, and the loss of heat shield tiles.

It would also explain why SpaceX decided to leave Starship in place and conduct repairs at the pad. Super Heavy Booster 7, which suffered a dramatic plumbing failure during an early proof test, was moved back to one of Starbase’s covered assembly bays for repairs. Had Ship 24’s incident been severe, it would have likely left the pad as well. The fact that Ship 24 did not move indicates that the failure was fairly minor and contained, only impacting some easily-replaceable plumbing.

Additionally, SpaceX appears to have moved Raptor heat shield components and a missing cover for one of Ship 24’s four flaps to the pad since the incident. On top of the team that has been working all weekend to repair the Starship, other sets of workers have set about closing out Ship 24’s ‘raceway’, which protects hundreds of feet of smaller plumbing and cables and a flight termination system that runs from the top to the bottom of the ship’s tanks; and some have begun preparing to fill gaps in Ship 24’s heat shield. Most of that work can be classified as ‘finishing touches’ and none of it would be prioritized if Ship 24 was not in decent shape.

Still, even minor damage is a setback. Ship 24’s next opportunity for redemption is a 10am to 10pm CDT window on Wednesday, June 1st, with backup windows available on Thursday and Friday.

Elon Musk reveals new information on Tesla’s AI5 chip for self-driving

Published

Elon Musk revealed new information on Tesla’s AI5, previously known as Hardware 5, chip, for self-driving, which will be manufactured by both Samsung and TSMC.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, Optimus humanoid robots, and other AI-driven features in both vehicles and other applications. It will be the successor to the current AI4, previously known as Hardware 4, which is currently utilized in Tesla’s newest vehicles.

Elon Musk reveals Tesla’s HW5 release date, and that it won’t be called HW5

AI5 is specially optimized for Tesla use, as it will work alongside the company’s Neural Networks to focus on real-time inference to make safe and logical decisions during operation. It was first teased by Tesla in mid-2024 as Musk called it “an amazing design” and “an immense jump” from the current AI4 chip.

It will be roughly 4o times faster, have 8 times the raw compute, 9 times the memory capacity, 5 times the memory bandwidth, and 3 times the efficiency per watt.

It will be manufactured by both TSMC and Samsung at their Arizona and Texas fab locations, respectively.

Here’s what Musk revealed about the chip yesterday:

Different Versions

Samsung and TSMC will make slightly different versions of the AI5 chip, “simply because they translate designs to physical form differently.” However, Musk said the goal is that its AI software would work identically.

This was a real concern for some who are familiar with chip manufacturing, as Apple’s A9 “Chipgate” saga seemed to be echoing through Tesla.

Back in 2015, it was found that Apple’s A9 chips had different performances based on who manufactured them. TSMC and Samsung were both building the chips, but it was found that Samsung’s chips had shorter battery life than TSMC-fabricated versions.

Apple concluded that the variance was about 2-3 percent. However, Tesla will look to avoid this altogether.

Release and Implementation into Vehicles

Musk said that some samples will be available next year, and “maybe a small number of units” would equip the chip as well. However, high-volume production is only possible in 2027.

This means, based on Tesla’s own timeline for Cybercab production in Q2 2026, early iterations of the vehicle would rely on AI4. Many believe AI4 can be utilized for solved self-driving, but the power of subsequent versions, including AI5 and beyond, will be more capable.

AI6 and Beyond

AI6 will utilize the same fabs as AI5, but there would be a theoretical boost in performance by two times with this version.

AI6 could enter volume production by mid-2028. However, AI7, which Musk only briefly mentioned, “will need different fabs, as it is more adventurous.”

Tesla’s fully autonomous Cybercab made its first appearance in the Asia-Pacific region at the 8th China International Import Expo (CIIE) in Shanghai on November 5, becoming the centerpiece of an event that drew 12 of the world’s leading automakers. 

The new model offers a glimpse into Tesla’s driverless ride-hailing future, and based on the reception of the event’s attendees, it appears that Elon Musk’s vision is something that still resonates with people.

Tesla showcases its driverless vision with the Cybercab

At this year’s expo, themed “Mobility, Infinite Possibilities,” Tesla’s futuristic two-seat Cybercab stood out as a showcase of complete autonomy. According to Tesla staff, the vehicle lacks both a steering wheel and pedals, relying entirely on Tesla’s cameras and an end-to-end neural network designed for full self-driving.

The Cybercab will ultimately serve in the company’s expanding Robotaxi fleet, a cornerstone of Elon Musk’s long-promised autonomous mobility network. During the event, a Tesla employee emphasized that the Cybercab’s model’s compact layout reflects real-world usage, as 92% of trips involve just one or two passengers, as noted in a Sina News report. Trips that require more passengers could easily be handled by the Model 3 and Model Y, which are both capable of seating four, or even five passengers.

Optimus, Tesla’s humanoid robot that is designed for both home and industrial use, was also present at the event. Similar to the Cybercab, Optimus also attracted quite a lot of attention from the event’s attendees.

Automakers reaffirm commitment to Chinese innovation

Other global automakers, including Volkswagen, Mercedes-Benz, and Honda, also displayed cutting-edge concept cars and intelligent systems, but few captured the same interest as Tesla’s bold showcase of its autonomy and robotics.

Beyond new models, this year’s CIIE highlighted a renewed focus on local innovation and collaboration in China’s rapidly evolving EV landscape. Executives from Volkswagen, Audi, and General Motors reaffirmed that their long-term strategies center on “in China, for China,” strengthening R&D operations and forming tech partnerships with domestic suppliers.

Tesla gets big nod on Musk comp package from Charles Schwab

“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value.”

Tesla got a big nod of approval on CEO Elon Musk’s newly-proposed compensation package from Wall Street firm Charles Schwab after many shareholders believed the company was aiming to go against the new pay structure for its frontman.

Yesterday, we reported on many Tesla investors threatening to leave Charles Schwab as their broker after it was assumed the firm would vote against Musk’s pay package. The impression was that Schwab would utilize the same voting strategies as Glass Lewis and Institutional Shareholder Services (ISS), which both said they would vote against the new compensation package.

However, Schwab reached out to TESLARATI directly yesterday to confirm that it had not made any statement on which way it would vote. It then confirmed to us that it would vote to support Musk’s pay package:

The statement to TESLARATI said:

“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved.”

Schwab also came out with a new statement just after that would be released to the public, stating that its delayed decision on the compensation package was due to its “structured process that focuses on protecting and promoting shareholder value.”

The firm uses a three-step program to determine its decision on a key vote like this one:

  1. board composition and quality
  2. actions a board has taken to drive strategy, deliver performance and manage relevant risks
  3. clarity and accessibility of reporting on key issues

It then said it applies its own internal guidelines and does not rely on recommendations from other firms, like Glass Lewis or ISS.

It continued:

“In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved.”

Charles Schwab then received kudos from the Tesla community on their decision to vote for Musk to receive this compensation package.
