SpaceX’s Falcon Heavy to ignite all 27 Merlin engines in early morning test
SpaceX is set to take another stab at the first integrated static fire test of Falcon Heavy Block 5 rocket, a milestone that will open the doors for its commercial launch debut just a handful of days later.
The window for the second Falcon Heavy’s static fire test will open at
If all goes well during these relatively routine procedures, SpaceX can be expected to announce a date for Falcon Heavy’s second-ever launch, likely no sooner than 4-5 days after the static fire is completed. In other words, a flawless performance tomorrow could permit a launch date as early as April 9-10. Launching fewer than four days after completing static fire testing is rare even for Falcon 9, which has the luxury of far less complexity (and data produced) relative to Falcon Heavy, which has only flown once and
Three months after Falcon Heavy’s February 2018 debut, SpaceX debuted Falcon 9 in its upgraded Block 5 configuration, featuring widespread changes to avionics, software, structures, thermal protection, and even uprated thrust for its Merlin engines. Falcon Heavy Flight 1 was comprised of Block 2 and Block 3 variants of the Falcon 9’s umbrella V1.2 Full Thrust configuration, which debuted in December 2015. Both side boosters – Block 2s – were flight-proven and had previously launched in 2016, while the rocket’s heavily modified center core was effectively a new version of Falcon 9 based on Block 3 hardware.
One of the biggest goals of Block 5 / Version 6 is ease of reusability. In

Block 5 has improved payload to orbit. Improved redundancy. Improved reliability. It’s really better in every way than Block 4. I’m really proud of the SpaceX team for the design.
– SpaceX CEO Elon Musk, May 2018
A different different rocket
Given just how extensive the changes made with Block 5 are, Falcon Heavy Flight 2 is drastically different than its sole predecessor, emphasized by the 13+ months SpaceX has taken to go from Flight 1 to Flight 2. Had SpaceX been able to successfully recover Falcon Heavy’s first center core (B1033) after launch, its quite likely that the company would have attempted to refly the rocket’s three landed boosters a bit sooner than April 2019, but the booster’s failed landing threw a bit of a wrench in the production plan.
After intentionally expending almost a dozen recoverable Block 3 and 4 Falcon 9 boosters in 2017 and 2018, SpaceX’s fleet of flightworthy cores had been reduced to a tiny handful. Interrupting Falcon 9 Block 5’s production ramp would have likely become a bottleneck for 2018’s launch cadence, and may well have contributed to SpaceX falling short from its planned 30 and then 24 launches last year with a still-impressive 21. Building an entirely new Falcon Heavy center core was simply not a priority as SpaceX required all production hands on deck to build enough Block 5 boosters to avoid major launch delays.
As a result, SpaceX delayed the production of the first Falcon Heavy Block 5 center core by ~6 months and ~8 boosters, shipping the rocket – presumed to be B1055 – to McGregor, Texas for static fire acceptance testing in Q4 2018. The center core arrived in Florida in mid-February 2019, following both side cores and a payload fairing.
Ultimately, SpaceX is likely to conduct Falcon Heavy’s first commercial launch with about as much caution as could be observed during the unique launches of SSO-A (the first triple-

SpaceX just locked up a NASA record no other U.S. spacecraft can touch
SpaceX’s Crew-13 Dragon reached the ISS in under eight hours, and NASA confirmed a record.
SpaceX now owns every spot on the list of the five fastest trips a U.S. spacecraft has ever made to the International Space Station, and its newest entry beat the old mark by more than four hours.
Crew Dragon Grace docked to the forward port of the station’s Harmony module at 7:05 p.m. ET on October 1, just 7 hours and 55 minutes after lifting off from Space Launch Complex 40 at Cape Canaveral. NASA confirmed the milestone in a space station blog update, writing that the flight “marked the fastest launch‑to‑docking of a U.S. spacecraft in the history of the International Space Station.”
The previous U.S. record also belonged to Dragon. SpaceX’s uncrewed CRS-31 cargo mission reached the station in a little over 12 hours in November 2024. The fastest crewed trip before last week was Crew-11, which took 14 hours and 43 minutes in August 2025, according to Space.com.
A post that Elon Musk reposted on Monday filled out the rest of the ranking. Behind Crew-13, CRS-31 and Crew-11 sit Axiom’s Ax-2 mission at 15 hours and 35 minutes and NASA’s Crew-4 at 15 hours and 44 minutes. All five flew on Dragon.
SpaceX turned a heralding moment for Starship into its greatest
Crew-13 carried NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov. NASA had projected a docking around 8 p.m. ET, as Teslarati reported the day before launch, and Dragon arrived nearly an hour early. Our launch day coverage noted that the flight was lined up to be the quickest Crew Dragon transit yet.
The speed came from timing more than hardware. SpaceX’s Julianna Scheiman said the station “was in an opportune spot in space,” which let Dragon start closing the gap almost immediately after reaching orbit. “This is close to the fastest it could be,” she added. Most Crew Dragon flights still take close to a day, using a series of Draco thruster burns to raise and phase their orbit before arrival.
Dragon’s next job at the station is a departure. NASA said Monday it is targeting 8:05 a.m. ET on Wednesday, October 7, for Crew-12 to undock, setting up a splashdown off the coast of California around 11:34 a.m. on Thursday. Clearing that port makes room for CRS-35, a cargo Dragon carrying the final set of iROSA solar arrays.
Dragon remains NASA’s only operational ride to the station while Boeing’s Starliner stays grounded, and the agency recently added Crew-15, Crew-16 and Crew-17 to SpaceX’s contract in a $946 million modification.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.

Elon Musk follows Trump’s lead, says a SpaceX name change is coming
Elon Musk says SpaceXAI will become SpaceXSI, marking its second rebrand in under three months.
Elon Musk wants to rename his artificial intelligence company again, less than three months after its last rebrand.
In a string of posts on X early Sunday morning, Musk wrote “No more AI,” followed by “SI” and “It’s better.” He then added, “SpaceX is a super intelligence company.” When a user asked whether SpaceXAI could become SpaceXSI, Musk replied, “Yes, we will make that change.”
The posts extend a terminology push that began at the White House last week. On September 29, President Donald Trump signed an executive order directing federal agencies to replace “artificial intelligence” and “AI” with “Super Intelligence” and “SI” on government websites, policy documents and press releases. The same day, Musk sat beside Trump as the heads of the largest AI companies signed a voluntary safety accord, as Teslarati reported. Speaking to reporters afterward, Musk caught himself mid sentence: “I think it is worth highlighting the positive benefits of A.I. … S.I., pardon me.”
Elon Musk and Trump are closer than ever, and Tesla could be the big winner
SpaceXSI would be the third name for the business since February. SpaceX acquired xAI on February 2 in a deal that valued the combined company at $1.25 trillion. In May, Musk said xAI would be dissolved as a separate company, and on July 6 the division adopted the SpaceXAI name and a new logo that placed the xAI letters inside the SpaceX identity.
Musk gave no timeline. He did not say whether SpaceXSI would be a legal name change or a branding update, whether the @SpaceXAI handle on X would change, or how the shift would apply to products like Grok. The company had not issued a formal announcement as of Sunday morning.
The change would reach well beyond a chatbot. SpaceXAI now houses Grok, the X platform, the Colossus training clusters in Memphis and the coding tool Cursor, which SpaceX acquired in August. It also runs the orbital compute effort SpaceX is building around Nvidia hardware, which Musk said during the company’s first earnings call would be exclusive to Nvidia.
It’s unclear if rivals like Anthropic, OpenAI, Google, Meta and Nvidia have plans to also rename their companies or products. OpenAI CEO Sam Altman has continued to say “AI” in public, while Nvidia CEO Jensen Huang has gone partway, describing data centers as “super intelligence factories.”
The rename would also line up SpaceX’s AI branding with the federal government’s language as Musk takes on a new advisory role at the Pentagon, where he is helping lead the Project Meridian study on the future of warfare.
