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’s Boring Company selected for Universal Orlando tunnel project
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe.
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project.
The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.
The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.
Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.
The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.
For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.
“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.
The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.

Elon Musk tops Forbes’ list of America’s 250 greatest innovators
The ranking places Musk at the top of modern American innovation.
Elon Musk has been ranked No. 1 on Forbes’ inaugural list of America’s 250 Greatest Innovators. The ranking places Musk at the top of modern American innovation as the publication kicks off a series celebrating the nation’s 250th anniversary.
Forbes described innovation as “the grease in the economic engine” and the force that transforms industries and creates new ones. The publication highlighted that its honorees are not just inventors, but business leaders who successfully bring breakthroughs to market.
Musk, 54, was ranked No. 1 in this year’s list. Forbes noted that he is “the only person in history to have founded (or grown from nearly nothing) five companies, each with multibillion-dollar valuations, each in a different industry.” Those companies include Tesla, SpaceX, Neuralink, xAI, and The Boring Company.
Forbes’ methodology began with nearly 1,000 nominees submitted by its reporters. A panel of judges, including venture capitalist Jim Breyer, journalist Kara Swisher, and strategy expert Rita McGrath, ranked candidates based on creativity, breadth, engagement, disruption, and commercial impact. Artificial intelligence tools, including ChatGPT and Gemini, were also used to assess candidates before editors finalized the rankings.
The publication noted that more than one-third of the list consists of women and people of color, reflecting shifts in innovation and entrepreneurship over time. All individuals listed are also American citizens, though many were born abroad, including Musk himself. Musk was born in Pretoria, South Africa.
Ranked No. 2 is Jeff Bezos, 61, who Forbes credited with upending America’s $7.4 trillion retail industry through Amazon before pioneering cloud computing with Amazon Web Services. The publication highlighted that Bezos now focuses on space exploration through Blue Origin and artificial intelligence manufacturing systems at Prometheus.
At No. 3 is Bill Gates, 70, who helped launch the personal computing revolution and built Microsoft into the dominant force in workplace software. Forbes also highlighted Gates’ reinvention at age 50 as a data-driven philanthropist, including his role in helping eradicate polio from India.

Tesla Model Y tops California vehicle sales despite Elon Musk backlash
Data from the California New Car Dealers Association (CNCDA) showed the Model Y outsold its nearest competitor by more than 50,000 units.
The Tesla Model Y was California’s best-selling new vehicle in 2025 for the fourth straight year, despite protests against CEO Elon Musk and a changeover to the Model Y’s updated variant that caused a pause in production and deliveries early in the year.
Data from the California New Car Dealers Association (CNCDA) showed the Model Y outsold its nearest competitor by more than 50,000 units, according to KRON4.
The Model Y recorded 110,120 registrations in California in 2025. The second-best-selling vehicle, the Toyota RAV4, posted 65,604 units, followed by the Toyota Camry at 62,324. The Tesla Model 3 ranked fourth with 53,989 sales, ahead of the Honda Civic at 53,085 units.
Despite leading the state, Model Y sales have trended downward year-over-year. Registrations fell from 132,636 in 2023 to 128,923 in 2024, and then to 110,120 in 2025. Overall Tesla sales in California also declined, dropping from 238,589 in 2023 to 202,865 in 2024 and 179,656 in 2025.
The slowdown comes as the federal $7,500 EV tax credit ended, removing a key incentive that had supported electric vehicle demand for years.
“Tesla has a few advantages. Tesla, as a brand, has a status, cache, so I think folks in certain parts of the Bay. Owning a Tesla is a thing. I think that’s breaking down over time, especially given the political controversies surrounding Mr. Musk,” CNCDA President Brian Maas said.
California saw multiple anti-Musk protests in 2025, along with notable reports of consumer-owned Teslas being vandalized and attacked by protesters and activists. The fact that the Model Y and Model 3 remained strong performers in California is then a testament to the quality and value of the two vehicles.
Tesla’s sales of the Model Y and Model 3 might see an increase this year, as the company has announced that it is sunsetting its two more expensive cars, the Model S and Model X. With the Model S and Model X retired, more consumers will likely go for the Model Y and Model 3.
“Maybe the Model S has outlived its usefulness in terms of attracting customers. It’s no surprise the ones they kept are the Model Y and Model 3,” Maas noted.
