SpaceX will transition all launches to Falcon 9 Block 5 rockets after next mission
SpaceX’s 13th reuse of a Falcon 9 booster marked the second-to-last orbital mission of older boosters before the rocket’s highly reusable Block 5 upgrade takes over all future commercial launches.
If only for the staggering rise of SpaceX’s program of reusable rockets, June 4’s Falcon 9 launch was novel and thrilling in part because its flight-proven booster was intentionally stripped of all reuse-related hardware to bestow as much performance as possible on the mission’s large geostationary communications satellite payload, named SES-12. While this practice of intentionally expending non-Block 5 flight-proven boosters after launch has actually been fairly common over the course of the last seven Falcon 9 reflights, excluding Falcon Heavy – SpaceX is, in essence, betting heavily on the viability and success of the rocket’s quasi-final Block 5 upgrade.

Following June 4’s SES-12 launch, after which Falcon 9 S1 (B1040, previously flown on the September 2017 launch of a classified X-37B spaceplane) arced down its final parabola into the Atlantic, SpaceX has just a single commercial launch of a Block 4 booster scheduled. In fact, that launch happens to be next up on the company’s manifest: currently no earlier than (NET) June 28, CRS-15 will see the same booster (B1045) that launched NASA’s TESS exoplanet observatory scarcely ten weeks prior send a refurbished Cargo Dragon to the International Space Station. After CRS-15, which will also see its booster expended in the Atlantic, just one flightworthy Block 4 rocket will remain in SpaceX’s fleet, and that Falcon 9 booster is understood to be undergoing refurbishment for its final reflight. That mission, however, is a suborbital demonstration designed to prove that SpaceX’s Crew Dragon spacecraft can wrest its human passengers out of harm’s way in the event of a launch vehicle failure during flight (SpaceX already proved it can accomplish the same task while the rocket is still on the launch pad in a 2015 demo).

No turning back now
While a critical path for SpaceX’s future of reliably delivering crew to orbit, its suborbital nature makes categorically distinct from past and future Falcon launches, all of which have been conducted with the intent of placing payload(s) into Earth orbit. Thus we arrive back at B1045 and CRS-15, currently scheduled as both SpaceX’s next launch and the final orbital mission before Falcon 9/Heavy Block 5 becomes the company’s only operational route to space for at least the next two years, give or take half a year. It’s thus somewhat poetic that the booster tasked with CRS-15 will easily smash SpaceX’s previous record for refurbishment (135 days) by almost a factor of two, going from drone ship recovery to reflight in as few as 71 days. Whatever it becomes, that refurbishment record will likely be broken by the first Block 5 reflight, a trend that will almost certainly continue until SpaceX reaches Musk’s fabled 24-hour turnaround, perhaps before the end of next year.

Extrapolating from the launch company’s recent history, the culmination of CRS-15 will potentially leave SpaceX with as few as two Falcon 9 Block 5 boosters as its entire flight-ready rocket fleet, despite anywhere from 12 to 16 launches remaining on the second half of the company’s 2018 manifest. Currently standing at six boosters produced in 2018, roughly eight to be completed before the end of the year per COO and President Gwynne Shotwell (in this case likely boosters B1048-1056), an achievement that would grow the ranks of the company’s fleet of new Block 5 boosters to ten total. But, assuming a core is delivered from the Hawthorne factory every month, SpaceX will need to reuse Block 5 boosters as early as July to prevent considerable delays to their 2018 manifest, delays that would undoubtedly push multiple missions into 2019.
Here’s to hoping that the Block 5 upgrade is as incredible of a success as SpaceX has designed it to be. Follow the Teslarati team for real-time updates, glimpses behind the scenes, and photos from Teslarati’s East and West Coast photographers.

NASA sends humans to the Moon for the first time since 1972 – Here’s what’s next
NASA’s Artemis II launched four astronauts toward the Moon on the first crewed lunar mission since 1972.

NASA launched four astronauts toward the Moon on April 1, 2026, marking the first crewed lunar mission since Apollo 17 in December 1972. The Artemis II mission lifted off from Kennedy Space Center aboard the Space Launch System rocket at 6:35 p.m. EDT, sending commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian astronaut Jeremy Hansen on a 10-day journey around the far side of the Moon and back.
The mission does not include a lunar landing. It is a test flight designed to validate the Orion spacecraft’s life support systems, navigation, and communications in deep space with a crew aboard for the first time. If the crew reaches the planned distance of 252,000 miles from Earth, they will set a new record for the farthest any human has ever traveled, surpassing even the Apollo 13 distance record.
As Teslarati reported, SpaceX holds a central role in what comes next. The Starship Human Landing System is under contract to carry astronauts to the lunar surface for Artemis IV, now targeting 2028, after NASA restructured its mission sequence due to delays in Starship’s orbital refueling demonstration. Before any Moon landing happens, SpaceX must prove it can transfer propellant between two Starships in orbit, something no rocket program has done at this scale.
The last time humans left Earth’s orbit was 53 years ago. Gene Cernan and Harrison Schmitt of Apollo 17 were the final people to walk on the Moon, a record that stands to this day. Elon Musk has long argued that returning is not optional. “It’s been now almost half a century since humans were last on the Moon,” Musk said. “That’s too long, we need to get back there and have a permanent base on the Moon.”
The Artemis program involves 60 countries signed onto the Artemis Accords, and this mission sets several firsts beyond distance. Glover becomes the first person of color to travel beyond low Earth orbit, Koch the first woman, and Hansen the first non-American astronaut to reach the Moon’s vicinity. According to NASA’s live mission updates, the spacecraft’s solar arrays deployed successfully after liftoff and the crew completed a proximity operations demonstration within the first hours of flight.
Artemis II is step one. The Moon landing and the permanent lunar base come later. But after more than five decades, humans are heading back.

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.
