SpaceX takes simplicity to new extremes with two new Starship mechanisms
In the first two parts of a three-part interview with YouTube creator Tim Dodd, SpaceX CEO Elon Musk has delved into two new Starship and Super Heavy mechanisms that take his pursuit of simplicity to new extremes.
Around the turn of the month, Starship’s first flightworthy Super Heavy booster was outfitted with a niche form of aerodynamic control surfaces known as grid fins. Those multi-ton car-sized fins have been expected ever since the original form of Starship was first revealed in 2016. What was unexpected, however, was the fact that Booster 4’s grid fins quite clearly had no retraction or deployment mechanism and were instead fixed in a deployed position after installation.
Meanwhile, just a month after SpaceX performed a partial test of the mechanisms meant to latch Starship and Super Heavy together and deploy the ship in flight, Musk says that SpaceX has also decided to almost entirely remove any recognizable separation mechanism.
In rocketry, there are generally two distinct types of launch vehicle separation strategies. All require some kind of actuating latch or frangible bolts to attach and detach stages. The differences arise during stage separation. Some rockets (particularly Russian vehicles) rely on hot staging, in which a separating stage will ignite its engine(s) slightly before or at the same time as its released, blasting the stage below it. More commonly, rocket upper stages are jettisoned a significant difference from lower stages before igniting and heading towards orbit with either small solid rocket motors, small vernier thrusters, or – in SpaceX’s case – spring-like mechanisms that can be tested on the ground and reused.
Sidestepping decades of precedent, Musk says that Starship will have no separation mechanism at all. Instead, at some point during the design or testing process, Musk decided that a separation mechanism was entirely superfluous and that the same effect could be more or less replicated by using existing systems on Super Heavy. By using the booster’s gimballing Raptor engines to impart a small but significant rotation on the rocket moments before separation, Super Heavy could effectively flick Starship away from it – a bit like how SpaceX currently deploys Starlink satellites from Falcon by spinning the upper stage end over end and letting the spacecraft just float away thanks to centripetal forces.
Because Starship is something like five times heavier than Super Heavy at stage separation, the ship would effectively float away from the booster in a straight and stable line, use cold gas thrusters to settle its propellant, and ignite its six Raptor engines to head to orbit. In return for the slightly unorthodox deployment profile, if this new approach works, SpaceX can entirely preclude the development of a pusher/spring system capable of pushing a ~1300 ton Starship away from Super Heavy. That approach is possible on Starship in large part because the ship’s six Raptor engines are completely tucked away inside a skirt, meaning that there is zero chance of nozzles being damaged by impacting the booster interstage.
The situation with Super Heavy’s grid fins is not dissimilar. By keeping the fins deployed at all times, SpaceX doesn’t need to develop a complex retraction mechanism that maintains a mechanical linkage while still providing enough strength to push and drag a several-hundred-ton rocket around at hypersonic speeds.
Notably, during Tim Dodd’s tour and interview, Musk revealed that another SpaceX employee – not him – was responsible for that design change, throwing up a bit of a foil to the common notion that Musk is very authoritarian and inflexible as chief engineer. Combined with a surprisingly elegant and responsive five-step approach to engineering, it’s clearer than ever that there is a great deal of well-considered method behind the surface-level madness of some of Musk and SpaceX’s less intuitive decisions.
Elon Musk tends to use social media platform X as his personal platform to express himself, so much so that critics tend to allege that the CEO is no longer serious about his numerous companies.
As per Musk, he is still very much in wartime CEO mode, despite all the jokes and fun posts about Ani on X.
Elon Musk leads several prolific companies, much more than the average CEO. And while Tesla is the only publicly traded entity that he currently leads, Musk is so visible that everyone across the internet pretty much has a strong opinion of him one way or another. For his longtime supporters and followers, however, what truly matters is if Musk is locked in.
Considering that Elon Musk’s feed on X has recently been filled with AI imagery, a good portion of which involve AI-rendered women, some X users have expressed concerns that the CEO may be losing focus once more. Musk responded to one such user by highlighting his very busy schedule and his numerous active projects.
Needless to say, Elon Musk is still locked in. He is still in “wartime CEO” mode.
As per the CEO, even his recent AI posts about AI are “part of a broader vision and strategy.” He also highlighted that SpaceX’s Starship Flight 10 is launching in a few days, xAI’s Grok 5 is starting its training next month, and Tesla’s Autopilot V14 is also coming next month. As per Musk, “long-term strategy is compelling.”
Elon Musk’s comments are quite accurate. While he may seem to spend all his time on X, after all, he is very much still neck-deep in all his companies’ projects. There is a reason why Musk became known as a visionary, and a lot of it is because he really is intimately involved in all of his companies’ projects.

Tesla watchers spot mysterious castings at Fremont Factory
The castings seem to be quite new, as they do not seem to match any of the castings that are currently being used for the Model Y.
A recent flyover of the Fremont Factory has triggered speculations about Tesla’s ongoing initiatives that are yet to be unveiled publicly. This was hinted at by the sighting of some apparent vehicle castings around the factory that have never really been observed before.
A Fremont Factory flyover
In a recent update, drone operator Met God in Wilderness, who has been chronicling the progress and developments of the Fremont Factory for years, shared some footage from his August 14, 2025 flyover. Based on the video, the Fremont Factory seemed very much alive. Vehicles were being pumped out of the factory, and a rather interestingly covered car could be seen going around the test track.
What is quite fascinating about the footage from the Fremont Factory is the fact that the vehicles that were moving from the production line to the outbound logistics lot are not driven manually anymore. As per Tesla in previous updates, vehicles produced at the Fremont Factory navigate to the outbound logistics lot on their own using Unsupervised FSD.
Mysterious castings
Perhaps most interestingly, the drone operator also managed to capture some footage of some castings that were being gathered just outside one of the facility’s sprung structures. These castings seem to be quite new, as they do not seem to match any of the castings that are currently being used for the Model Y. This has brought speculations suggesting that the new components, which seem smaller than standard Model Y megacasts, may be for a different, perhaps more compact, vehicle.
As per Tesla in its second quarter earnings call, the company actually started the initial production of more affordable models sometime in June. These vehicles, as per Elon Musk, will be made available for consumers in the fourth quarter. “Given that we started in North America and that our goal is to maximize production with higher rates by the end of Q3, we’re going to keep pushing hard on our current models to avoid complexity… We’ll be running with the more affordable models available for everyone in Q4,” Musk said.

Shareholder group urges Nasdaq probe into Elon Musk’s Tesla 2025 CEO Interim Award
The SOC Investment Group represents pension funds tied to more than two million union members, many of whom hold shares in TSLA.
An investment group is urging Nasdaq to investigate Tesla (NASDAQ:TSLA) over its recent $29 billion equity award for CEO Elon Musk.
The SOC Investment Group, which represents pension funds tied to more than two million union members—many of whom hold shares in TSLA—sent a letter to the exchange citing “serious concerns” that the package sidestepped shareholder approval and violated compensation rules.
Concerns over Tesla’s 2025 CEO Interim Award
In its August 19 letter to Nasdaq enforcement chief Erik Wittman, SOC alleged that Tesla’s board improperly granted Musk a “2025 CEO Interim Award” under the company’s 2019 Equity Incentive Plan. That plan, the group noted, explicitly excluded Musk when it was approved by shareholders. SOC argued that the new equity grant effectively expanded the plan to cover Musk, a material change that should have required a shareholder vote under Nasdaq rules.
The $29 billion package was designed to replace Musk’s overturned $56 billion award from 2018, which the Delaware Chancery Court struck down, prompting Tesla to file an appeal to the Delaware Supreme Court. The interim award contains restrictions: Musk must remain in a leadership role until August 2027, and vested shares cannot be sold until 2030, as per a Yahoo Finance report.
Even so, critics such as SOC have argued that the plan does not have of performance targets, calling it a “fog-the-mirror” award. This means that “If you’re around and have enough breath left in you to fog the mirror, you get them,” stated Brian Dunn, the director of the Institute for Comprehension Studies at Cornell University.
SOC’s Tesla concerns beyond Elon Musk
SOC’s concerns extend beyond the mechanics of Musk’s pay. The group has long questioned the independence of Tesla’s board, opposing the reelection of directors such as Kimbal Musk and James Murdoch. It has also urged regulators to review Tesla’s governance practices, including past proposals to shrink the board.
SOC has also joined initiatives calling for Tesla to adopt comprehensive labor rights policies, including noninterference with worker organizing and compliance with global labor standards. The investment group has also been involved in webinars and resolutions highlighting the risks related to Tesla’s approach to unions, as well as labor issues across several countries.
Tesla has not yet publicly responded to SOC’s latest letter, nor to requests for comment.
The SOC’s letter can be viewed below.
