SpaceX’s first orbital-class Starship and Super Heavy to return to launch pad next week
CEO Elon Musk says that SpaceX could return the first orbital-class Starship prototype and its Super Heavy booster to the launch site after rolling the rockets back to the factory for finishing steps.
In response to a video of Super Heavy Booster 4 (B4) returning to the build site, Musk rather specifically stated that both Booster for and Starship 20 (S20) will return to the orbital launch pad on Monday, August 16th. SpaceX returned Ship 20 to its ‘high bay’ vertical integration facility mere hours after the Starship was stacked atop a Super Heavy booster (B4) for the first time ever on August 6th. For unknown reasons, perhaps due to high winds, Booster 4 spent another five days at the pad before SpaceX finally lifted it off the orbital launch mount and rolled it back to the high bay, where it took Ship 20’s place on August 11th.
Almost immediately after S20’s August 6th return, its six Raptor engines were removed to make way for an engine-less proof test campaign that Musk has now implied could start as early as next Monday. Mirroring S20, SpaceX also begin uninstalling Super Heavy Booster 4’s 29 Raptor engines the same day it returned to the high bay.
Around 12 hours after the process began, SpaceX appeared to have removed 14 (just shy of half) of Super Heavy B4’s Raptor engines – a pace almost as spectacular as their 12-18 hour installation a bit less than two weeks prior. Aside from making engine removal dramatically easier, Musk says that SpaceX moved Ship 20 and Booster 4 back to the build site to expedite some minor final integration work – namely “small plumbing and wiring.”
However, aside from Raptor removal, the most obvious and significant work ongoing since the pair’s return to the high bay is the process of inspecting Starship S20’s heat shield and repairing or replacing broken, chipped, and loose tiles. Not long after Ship 20 arrived back at the build site, workers in boom lifts began a seemingly arduous process of inspecting the Starship’s nose heat shield and marking – with colored tape – hundreds of tiles with cracks, chips, or other less visible issues.
After several days of inspections and hundreds of tiles marked, SpaceX finally began the process of removing off-nominal tiles early on August 12th. According to NASASpaceflight.com, that removal process is not particularly easy and can require the use of power tools to effectively cut tiles off their embedded mounting frames. Given the amount of force required, some level of care is also almost certainly needed to avoid damaging any adjacent tiles, which could quickly cause a minor misstep to exponentially spread. Nevertheless, a small team of SpaceX technicians seemingly managed to remove no less than several dozen (and maybe 100+) broken tiles in a few hours.

Up next, those removed tiles will need to be replaced. Still, it remains to be seen if SpaceX will choose to fully complete Starship S20’s “98% done” heat shield before sending the ship back to the launch site for proof and static fire testing. To a degree, putting Starship through a gauntlet of ground tests with a full heat shield installed would be an excellent test of the resilience of its thermal protection system to major thermal stresses from frosty steel skin and expansion/contraction during fueling, as well as violent vibrations during static fires.
However, Starship S20’s heat shield is already so close to completion that it might be only marginally less valuable to save time by testing the vehicle as soon as possible.

To an extent, Booster 4 is a much simpler case as Super Heavy needs to major thermal protection. However, according to Musk, some or all of Super Heavy’s 29 Raptor engines will need their own miniature thermal protection system – perhaps a flexible blanket-like enclosure not unlike what SpaceX uses to partially protect Falcon booster engines during reentry. It remains to be seen if Booster 4 will return to the launch site without engines for cryogenic proof testing or if SpaceX will install heat shielded Raptors before starting the first flightworthy Super Heavy’s first test campaign.

SpaceX files confidentially for IPO that will rewrite the record books
SpaceX files confidentially for a record-breaking IPO targeting a $1.75T valuation and $80B raise, driven by Starlink growth and its xAI merger.
Elon Musk’s rocket and satellite company submitted its draft registration to the U.S. Securities and Exchange Commission today for an initial public offering, targeting June at a $1.75 trillion valuation. This would be the largest in history.
SpaceX has filed confidentially with the SEC, first reported by Bloomberg. SpaceX would be valued above every S&P 500 company except Nvidia, Apple, Alphabet, Microsoft, and Amazon.
The filing uses a confidential process that allows companies to work through SEC disclosures privately before initiating a public roadshow. With a June target, official details through a formal prospectus is expected to go public in April or early May, after which SpaceX must wait at least 15 days before beginning investor marketing.
While SpaceX is best known for its Falcon 9 and Starship rockets, the $1.75 trillion valuation is anchored by Starlink, its satellite internet service. Starlink ended 2025 with 9.2 million subscribers and over $10 billion in revenue, which is a figure analysts project could reach a staggering $24 billion by the end of 2026. A February all-stock merger with xAI, Musk’s artificial intelligence venture, further boosted the valuation.

Bank of America, Goldman Sachs, JPMorgan Chase, and Morgan Stanley are lined up as senior underwriters. SpaceX is also considering a dual-class share structure to preserve insider voting control, and plans to allocate up to 30% of shares to retail investors, which is roughly three times the typical norm.

Elon Musk hints at “official ceremony” with throwback photo to close Tesla Model S, Model X chapter
Elon Musk promises an official ceremony to mark the end of Tesla Model S and Model X production.
Tesla has officially begun winding down production of the Model S and Model X, sending farewell emails to U.S. customers on March 27 and updating the website to reflect the end of the line. Shoppers visiting Tesla.com now find only a limited set of Model S and Model X inventory units available for purchase, with no option to configure a new factory build. The move formalizes what CEO Elon Musk announced on the company’s Q4 2025 earnings call in January, when he said it was “time to basically bring the Model S and X programs to an end with an honorable discharge.”
Musk posted on X a throwback photo of himself speaking at the Model S production launch in 2012, and noting “We will have an official ceremony to mark the ending of an era. I love those cars.”
The mention of an official ceremony is notable. Tesla has not held a formal farewell event for a vehicle before, and Musk’s wording suggests this will be something deliberate rather than a quiet line shutdown. Given that Musk’s X post shows a photo of him on stage with a microphone in front of an audience at the Fremont factory, it wouldn’t be too far-fetched to expect a closing ceremony to take place at the same location. Perhaps? Whether it becomes a public event, a private gathering for employees, or a livestreamed moment on X remains to be seen.
Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.

The Model S first went on sale nearly fifteen years ago and was Tesla’s first fully in-house designed vehicle, proving that an electric car could be fast, desirable, and capable of long distance on a single charge. The Model X followed in 2015, turning heads with its unmistakable and distinctive falcon-wing doors, while becoming one of the first all-electric SUVs on the market. Tesla’s two flagship vehicles would ultimately push legacy automakers to take all-electric transportation seriously and help fund development of the more affordable Model 3 and Model Y.
By 2025, however, both models had been reduced to a rounding error in Tesla’s sales figures. Musk was direct about what comes next, stating “We are going to convert that production space to an Optimus factory. It’s part of our overall shift to an autonomous future.”

That shift is already underway. Tesla officially started Optimus Gen 3 production at its Fremont factory in January 2026, with the line targeting a run rate of one million units per year. The Gen 3 robot features 22 degrees of freedom per hand, runs on Tesla’s AI5 chip, and shares the same neural network architecture as Full Self-Driving. A dedicated Optimus factory at Gigafactory Texas is also under construction, with a planned annual capacity of 10 million units. The production lines that once built the Model S and Model X are being converted to support that ramp.
Tesla confirmed it will continue to support existing owners with service, software updates, and parts for as long as people own the vehicles. For buyers still interested in a new example, remaining U.S. inventory is discounted and the window is closing fast.

The announcement follows reports of Optimus Gen 3 appearing at the Tesla Diner in Los Angeles, where it was observed serving and moving about until sunset. Images and videos shared by observers captured the robot in action, highlighting its progress in real-world mobility.
Tesla had aimed to showcase the production intent version of Optimus Gen 3 during the first quarter of 2026, positioning it as a major step toward factory deployment and eventual commercial availability. Musk has described the robot as featuring advanced capabilities, including highly dexterous hands with significant degrees of freedom, powered by Tesla’s AI systems for complex tasks.
This minor postponement aligns with Tesla’s iterative approach to development. Earlier statements from Musk indicated that Gen 3 would represent the most advanced humanoid robot yet, designed primarily for internal factory use before scaling to external customers.

Production timelines point toward low-volume output starting in the summer of 2026, with volume ramp-up targeted for 2027. The delay underscores the company’s commitment to quality over speed, ensuring the robot meets rigorous standards for safety and performance in practical environments.
Optimus represents a cornerstone of Tesla’s long-term vision beyond electric vehicles. Musk has repeatedly emphasized that successful humanoid robotics could transform industries by addressing labor shortages and enabling new forms of productivity.
Competitors in the space continue to advance their own platforms, yet Tesla’s vertical integration, from custom actuators to end-to-end AI training, positions Optimus as a potential leader. Community reactions on social media range from excitement over visible progress to impatience with shifting timelines, a familiar pattern in Tesla’s innovation journey.
Investors and enthusiasts view Optimus as critical to Tesla’s valuation, potentially surpassing its automotive business in scale. With the robot already demonstrating walking and basic interactions, the finishing touches likely involve software polishing, hardware fine-tuning, and reliability enhancements.
Musk’s update suggests the reveal could arrive in the coming weeks or months, maintaining momentum toward broader deployment.
As Tesla pushes the boundaries of physical artificial intelligence, this latest development keeps Optimus in the spotlight. The company continues to prioritize rapid iteration while delivering on its promises to shareholders and customers. The robotics revolution at Tesla appears closer than ever, promising profound impacts on manufacturing, services, and daily life in the years ahead.
