The first commercial launch of SpaceX’s Falcon Heavy rocket – this time in a Block 5 configuration – is as few as ten days away from a targeted window beginning at 6:36 pm EST (22:36 UTC), April 7th. That target hinges on whether Falcon Heavy is ready and able to roll out to Pad 39A and successfully conduct its first integrated static fire, currently scheduled on April 1st.
The payload for this mission – communications satellite Arabsat 6A – had its original Lockheed Martin manufacturing and SpaceX launch contracts signed back in the first half of 2015, while the 6000 kg (13,200 lb) spacecraft was effectively completed once it was shipped from California to Florida at the start of 2019. After approximately 12 months of delays from an original launch target shortly after Falcon Heavy’s 2018 debut, Arabsat 6A’s four-year journey will hopefully reach completion in a geostationary transfer orbit. At the same time, the US Air Force says that it will be watching this launch – and the one meant to follow soon after – as a critical test along the path to fully certifying the powerful rocket for military launches.
As a pathfinder for an unproven rocket, SpaceX’s first Falcon Heavy launch suffered a number of likely minor to moderate anomalies as company engineers and technicians learned for the first time how the rocket actually behaves in the real world, under real-world conditions and operations. Case in point, the first integrated Falcon Heavy was taken through its first wet-dress rehearsal – in which the vehicle is filled with a
Despite the invaluable experience gained by those orchestrating the launch and those who built the vehicle, Falcon Heavy’s second launch may result in similar teething pains, particularly due to the fact that the rocket’s complete upgrade to Block 5 hardware likely necessitated significant design changes across the board. In other words, the rocket SpaceX aims to launch in early April may be quite a bit different from the vehicle that launched 14 months prior, creating much of the same uncertainty inherent in the first launch(es) of any new rocket. Still, many of the complex boosters’ connection and separation mechanisms that were flight-tested for the first time that February 
“Again, I don’t want to tempt fate. But this is a much stronger octaweb structure. It’s made of
“Biggest process change [for Block 5] was eliminating Tig welding of the thrust structure or “Octaweb” and the move to a bolted design but this made it much easier and faster to produce overall as well.” – SpaceX VP of Production Andy Lambert, April 2018
A step further, SpaceX CEO Elon Musk has indicated that one major section of Block 5 upgrades – moving from a welded to a bolted thrust structure (i.e. octaweb) – was expected to be a boon for Falcon Heavy, while also making octawebs far easier to manufacture, assemble, and even disassemble. According to Musk, new bolted octawebs are also “dramatically” stronger, a boon for Falcon Heavy boosters – particularly the center core – that need to survive forces multiple times stronger than those subjected upon Falcon 9 first stages.

Meanwhile, according to comments made by Air Force officials to Spaceflight Now, the USAF is looking at SpaceX’s Arabsat 6A and subsequent STP-2 Falcon Heavy launches as critical steps along the way to fully certifying the rocket for valuable military payloads. Currently, the only option available for military and NRO payloads past a certain weight or in need of exceptionally high-energy orbits is ULA’s Delta IV Heavy rocket, an extremely expensive ($300M+ per launch) rocket with a bad track record of schedule reliability.
An Air Force spokesperson this week confirmed the agreement to use previously-flown side boosters for the STP-2 mission. The center core will be new for the Arabsat 6A and STP-2 launches.
“This provides an early opportunity for the Air Force to understand the process for using previously-flown hardware with the goal to open future EELV missions to reusable launch vehicles,” the spokesperson said in response to an inquiry from Spaceflight Now.
SpaceX’s Falcon Heavy rocket could launch on its first commercial flight as soon as April 7. SpaceX will re-fly the side boosters on a Falcon Heavy launch this summer in a key demonstration for the Air Force to move closer to certifying reused rockets. https://t.co/guc7yaE7sH pic.twitter.com/FyaIS3Mlnf— Spaceflight Now (@SpaceflightNow) March 16, 2019
Given that STP-2 will need to reuse both of the Arabsat 6A Falcon Heavy’s side boosters, the USAF official also specifically noted that the military branch would be examining SpaceX’s refurbishment processes and the performance of the flight-proven stages with the intention of ultimately allowing reused rockets to launch military satellites. As such, the successful launch, landing, refurbishment, and re-launch of both Falcon Heavy side boosters (B1052 & B1053) will be doubly critical for SpaceX.

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 teases TSMC as potential Terafab partner
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.
