Hawthorne, we have a problem: SpaceX has too many boosters
Over the course of two years of concerted effort, SpaceX has matured its program of reusable rocketry into a truly staggering success. Over the 24 months since SpaceX first successful recovery of a Falcon 9 booster, there have been stumbles as recovery improved, but overall the company has accomplished 20 near-flawless landings of boosters over that period. Perhaps more impressively, following a handful of failed recovery attempts in 2016, SpaceX has successfully recovered 15 boosters without incident, with the vast majority of those attempts occurring in 2017.
2017 has ultimately been the best year yet for the launch company, marked by what will likely be 18 successful missions (after Iridium-4) for Falcon 9, five commercial reuses of flight-proven boosters, the activation of three essentially new launch facilities, and numerous additional accomplishments behind the scenes as the inaugural launches of Falcon Heavy and Crew Dragon rapidly approach. The success of reusability is arguably the sticking point here, and that success has meant that SpaceX rapidly accumulated a huge stock of recovered Falcon 9s, often to the extent that Elon Musk sometimes joked about running out of space for boosters.

While it may not be immediately clear if SpaceX is legitimately running out of space with which to store its fleet of boosters, reports of first stages being mothballed or even scrapped suggest that space may indeed be at a premium, or at least indicate that SpaceX is growing increasingly pragmatic as its reuse expertise expands.
This is to say that while there may be room to store a few additional boosters, the reality is that older Block 3 Falcon 9s were simply not designed with an expectation that they would affordably survive multiple reuses. As such, it should come as little surprise that SpaceX is choosing to expend at least a couple of upcoming launches featuring reused boosters. As of December 19, public information indicates that the West Coast launch of Iridium-4 – scheduled for Dec. 22 – will not attempt first stage recovery. While somewhat sad, the decision is entirely rational, and it appears all but certain that Iridium-4 will at a minimum feature an attempt at fairing recovery aboard the highly-modified recovery vessel Mr. Steven.

Public Falcon 9 tracking efforts on forums like Reddit and NASASpaceflight indicate that Block 3 boosters include 1029-1038, all of which debuted with their first launches in 2017, beginning with Iridium-1 in January. Of those ten distinct boosters, only two currently lack any future missions, 1032 and 1038; SpaceX has essentially worked the Block 3 fleet to its end-of-life, and that end will be efficiently sped up by simply expending those final reused boosters if or when they are reflown, Iridium-4 included.
For now, we only use those on super hot reentry missions. Will go to all Ti with Falcon 9 V5, which is a few months away.

Expending those older flight-proven boosters will allow SpaceX to both figuratively and literally replace Falcon 9’s less capable predecessors with Block 4s and eventually Block 5s, both of which are at least marginally more reusable than their predecessors. As reported by Musk himself a few days ago, Falcon 9 Block 5 is expected within a few months. Block 5 has seen considerable modifications made to Falcon 9, and all of those changes are intended to improve ease of reuse: SpaceX’s official goal for the upgrade is to enabled Falcon 9 first stages to be reflown as many as 10 times with little to no refurbishment and a lifespan of 100 flights with significant periodic refurbishment. As a result, it is possible that 2018 might feature a similar period of reused Block 4 launches sans any attempted recoveries.
In the meantime, we can wish the fairing recovery teams the best of luck and mourn several of the pioneers of reusable rocketry. Here’s to hoping that we are treated to a live view of each booster’s demise in homage to their achievements.

Tesla removes Model S and X custom orders as sunset officially begins
In a significant development that marks the beginning of the end for two of its longest-running models, Tesla has removed the custom order configurator for the Model S sedan and Model X SUV from its website.
Tesla has officially started the “honorable discharge” of the Model S and Model X with a massive move, removing the two vehicles from Custom Orders and only offering inventory options.
It is the latest move Tesla has made to pull the Model S and Model X from its lineup, a decision CEO Elon Musk announced during its last quarterly earnings call.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
In a significant development that marks the beginning of the end for two of its longest-running models, Tesla has removed the custom order configurator for the Model S sedan and Model X SUV from its website.
As of April 1, visitors to tesla.com/model-s and tesla.com/modelx are now redirected exclusively to limited inventory listings rather than a design studio, allowing buyers to select paint, wheels, interior options, or performance upgrades. Only pre-built vehicles currently in stock are available for purchase or lease.
Tesla CEO Elon Musk confirmed the change directly on X, posting: “Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.”

We will have an official ceremony to mark the end of an era.” Accompanying the statement was a throwback photo from the Model S production launch in 2012, underscoring the emotional weight of the decision.
Musk had first signaled the phase-out during the company’s Q4 2025 earnings call in January, describing it as time for an “honorable discharge” of the programs to free up resources at the Fremont factory for Optimus humanoid robot production and autonomous vehicle initiatives.
The Model S, introduced in 2012, and the Model X, which followed in 2015, were instrumental in establishing Tesla as a premium electric vehicle leader.
The sedan offered class-leading range and acceleration, while the SUV’s signature falcon-wing doors became an iconic feature. Together, they proved EVs could compete in the luxury segment. Yet sales volumes have dwindled in recent years as Tesla prioritized higher-volume Model 3 and Model Y vehicles.
The flagships now represent a tiny fraction of overall deliveries, making continued custom production inefficient as the company accelerates toward robotaxis and next-generation platforms.
Prospective buyers are urged to act quickly. Remaining U.S. inventory vehicles—some nearly new—may include incentives such as lifetime free Supercharging, Full Self-Driving (Supervised) capability, and premium connectivity, depending on configuration.
Leasing options start around $1,699 per month for select Model X units, though exact pricing and availability fluctuate. International markets, including Europe and China, have already seen similar restrictions in recent months.
The move aligns with Tesla’s broader strategy to streamline its lineup and redirect manufacturing capacity toward autonomy and AI-driven products. While some enthusiasts lament the loss of personalization, the company views the transition as necessary progress.
Tesla has indicated that once the current inventory sells out, new Model S and Model X vehicles will no longer be offered.
For loyal owners and fans, the promised “official ceremony” may provide a fitting send-off. In the meantime, the website change serves as a clear signal: the era of bespoke flagship Teslas has quietly concluded, and the focus has fully shifted to the future.

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.

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.
