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.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
-
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.
Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.
Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.

For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.
Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.
These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.
No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.
The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.
While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.
