SpaceX on track for biweekly launch cadence in the remainder of year
Weekly rapid reuse launches expected by 2019

Following a weekend of extraordinary accomplishments, seeing SpaceX flawlessly execute two missions – one with a reused first stage – in just over 48 hours of each other, the company has capitalized on a uniquely successful weekend and year and offered information about their future plans.
The launch of BulgariaSat-1 and Iridium-2 on Friday and Sunday respectively marked the eight and ninth launches of 2017 for SpaceX, and officials at the company are reportedly expecting to launch approximately 24 missions this year, meaning 15 more to come over the next 6 months. Given the recent demonstration of 48 hour launch cadence and a more regular schedule of biweekly launches in the past few months, an expectation of 15 more launches for 2017 lines up perfectly with a cadence of two launches a month from LC-39A Cape Canaveral and three Iridium launches from Vandenberg, which happens to be exactly what is currently manifested.
Originally manifested for up to 27 launches this year, successfully launching 24 missions, one of which might be the inaugural flight of Falcon Heavy, would be extraordinarily hard to ignore in an industry that has compared the launch industry to manufacturing beverage containers and argued that reuse is only sustainable with more than 20 launches a year on a company’s manifest.

SpaceX is now likely to undertake 24 launches this year, but the company also revealed this weekend that it intends to achieve a regular weekly launch cadence (52 launches per year) as soon as 2019. In a recent article, I speculated that we might begin to see regular weekly launches once both LC-39A and LC-40 were active, and that appears to be nearly correct. If SpaceX is to regularly conduct weekly launches by 2019, it is bound to begin shrinking its two week cadence as soon as is safe and possible. This will likely occur once Falcon Heavy has successfully flown several times from LC-39A, thus freeing SpaceX to deem the vehicle operational and less at risk of destroying one of their two Eastern pads.
There is also a tentative understanding that SpaceX is striving to construct and activate their planned Boca Chica, Texas launch complex by 2019. The successful reactivation of LC-40 and subsequent modification of LC-39A for Falcon Heavy will leave the brunt of SpaceX’s launch complex maintenance and construction teams free to focus entirely on the Texas facility sometime late this year or early next year, meaning that Boca Chica pad activation could certainly occur as early as 2019. This would leave the company with two fully operational all-purpose launch pads dedicated to Falcon 9 launches if they choose to retain LC-39A solely for Falcon Heavy and Commercial Crew launches, allowing them to reach weekly cadences even before the launches of Falcon Heavy, Commercial Crew contracts, and Vandenberg launches are accounted for.
One crucial factor playing into SpaceX’s ability to launch 52 times in a year is of course reusability, as it is hard to imagine SpaceX more than doubling their Falcon manufacturing capabilities in under a year and a half. Likely no coincidence, SpaceX simultaneously offered information to insurance underwriters about the increasing speed of their ability to launch, recover, and reuse first stages. More specifically, a spokesman of the company stated that the reuse of BulgariaSat-1’s Falcon 9 1029 took considerably less than half as long as the inaugural reuse of the stage that launched SES-10 earlier this year, implying that refurbishment and quality assurance checks for 1029 took something like four or five months total.
With SpaceX having debuted new titanium grid fins intended to speed up reuse on the Sunday launch of Iridium-2, the company is well on its way to transferring over to Block 4 (upgraded engine performance) and possibly Block 5 of Falcon 9 later this. Block 5 is expected to introduced major changes meant to replace aspects of the current Falcon 9 that require major refurbishment after recovery. Musk detailed these changes several months ago in a Reddit AMA (Ask Me Anything), mentioning that reusable heat shielding around the engines, improved landing legs, and titanium grid fins were the main aspects of a Block 5 of Falcon 9 meant to offer rapid reuse without refurbishment. In June 22nd interview on the Space Show, Gwynne Shotwell reiterated that this “final” version of Falcon 9 is expected to be able to launch, land, and relaunch with barely more than a thorough once-over, and ought to be capable of flying a dozen missions at least.

This final piece of the puzzle of weekly cadence fits in quite nicely. With a possible introduction date for Block 5 of late 2017 or early 2018, SpaceX will likely end production of Block 3 by the end of this year and transfer over entirely to the easily reusable Block 5. Assuming a continuing a trend of increasingly reuse-friendly customers, Hawthorne production capacity of approximately 20 Falcon 9s per year, and a plausibly significant reduction in launch costs due to more rapid and complete reuse, SpaceX could find themselves at the start of 2019 with a dozen or more launch vehicles that are each capable of conducting upwards of 10-12 highly affordable launches each.
Let there be no doubt: these are incredibly optimistic and difficult goals for the company to achieve on the timescale they have provided. However, given the number of beneficial changes likely to soon be made to both the launch vehicles and SpaceX’s manufacturing, launch, and refurbishment facilities in the next 6-12 months, those goals are realistically achievable, albeit with some likely delays. Regardless, things are beginning to get rather intense for SpaceX and for the launch industry in general.
Keep your eyes peeled for upcoming Teslarati coverage of SpaceX’s next July 4th launch and its static fire that is scheduled for as soon as this Thursday.

Tesla begins ‘honorable discharge’ of Model S, X with massive move
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.
