SpaceX’s next Falcon Heavy hits milestone as final rocket parts arrive in Florida
SpaceX has reached a critical milestone on the road to Falcon Heavy’s third flight: all major parts of the rocket – three boosters, an interstage, and a payload fairing – are now officially on-site at the company’s Pad 39A launch facilities.
This means that all that stands between SpaceX, the USAF, and the critical mission is the integration of the hardware into one vehicle, as well as the integration and encapsulation of all 24 customer satellites in the Falcon payload fairing. As noted by the USAF Space and Missile Systems Center (SMC), Falcon Heavy’s Space Test Program-2 (STP-2) mission will be exceptionally challenging and important for SpaceX for a variety of reasons.
Falcon Heavy: The Upper Stagening
Although the general performance of the three first stage boosters will be absolutely critical, the US Air Force’s STP-2 mission manages to cram in several additional major goals. First and foremost, all eyes will be on SpaceX’s Falcon upper stage (S2). Scheduled to last no less than several hours, the upper stage will be put through its paces like never before, requiring four separate ignitions and shutoffs of its Merlin Vacuum engine. For SpaceX, this may be the first time the company has ever attempted the feat – if any on-orbit testing has been done after completing customer missions, SpaceX has never commented on it.
Back in February 2018, Falcon Heavy’s launch debut also happened to mark the first flight-test of a true long-duration upper stage coast and third ignition, a spectacular success that sent Starman and a Tesla Roadster into a heliocentric orbit that now reaches beyond Mars. As such, SpaceX will by no means be walking into the challenges of STP-2 unprepared. In fact, the coast required on Flight 1 may have technically been more challenging than any one of the four separate burns S2 will need to perform on STP-2. However, combining the need to do all four burns and deployments rather quickly and in sequence, the critical need for accurate orbital insertions, and high standards of reliability and mission assurance expected by the USAF, STP-2 will easily be the hardest mission SpaceX has yet to attempt.
If SpaceX succeeds, the benefits will stretch far beyond simply satisfying an Air Force requirement and securing the USAF’s Falcon Heavy certification. Once SpaceX has rigorously demonstrated the reliability of Falcon 9’s upper stage for long coasts and high numbers of ignition events, the company will be able to apply that as a marketable product. Potential customers include the usual communications satellite operators desiring a direct-to-GEO insertion, saving time (and thus making money faster) by skipping the orbit-raising that comes with easier transfer orbits.
One major use-case – as demonstrated by Falcon Heavy’s interplanetary launch debut – is sending payloads beyond Earth orbit, a capability that NASA would undoubtedly take advantage of.
Reusability makes a surprise entrance
But wait, there’s more! In a predictable but still largely unexpected turn of events, the Air Force has also selected Falcon Heavy’s STP-2 mission as an opportunity to gain familiarity with the rocket reusability SpaceX is famous for. Falcon Heavy’s second mission and commercial launch debut – Arabsat 6A – used three all-new Block 5 boosters, two of which returned to land after gentle recoveries. Known as B1052 and B1053, the lightly-used boosters are now scheduled to become the first flight-proven orbital-class rockets launched on a Department of Defense (DoD) mission in 25 years, since the Space Shuttle’s final military mission in 1992.
If successful, SpaceX will help pave the way for the US military to seriously adopt reusable rockets and develop the “certification” procedures needed to do so. This will benefit all prospective US launch providers, not just SpaceX, but SpaceX will likely be the only company flying valuable payloads on flight-proven rockets until Blue Origin and ULA’s Vulcan achieve flight-proven certification for military launches. Much like regular certification often requires multiple launch demonstrations, flight-proven certification will likely be at least as – if not more – stringent. For New Glenn, that milestone might come as early as 2023-2025, while Vulcan – if a reusable engine section is ever actually implemented – is unlikely to even complete its launch debut – let alone first reuse – before 2025.
As such, SpaceX is quite literally half a decade ahead of its prospective competitors when it comes to certifying flight-proven rockets for high-value launches. Additionally, just the act of the USAF completing its development of a reusability certification process will likely encourage – if not directly lay the foundation for – NASA to seriously consider doing the same with its own launch services.

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.
