SpaceX hangar packed with Falcon Heavy Block 5 boosters for early April debut
For a company that rarely reveals anything without explicit intent, a February 28th video posted by SpaceX during the lead-up to Crew Dragon’s launch debut featured a surprise cameo: two Block 5 side boosters meant to support Falcon Heavy’s commercial debut and second launch ever.
Likely a subtle nod to close observers and fans, the inclusion of Falcon Heavy is a perfect bit of foreshadowing for the next launch set to occur from Pad 39A after Crew Dragon’s flawless orbital debut. As of now, Falcon Heavy Flight 2 is settling in on a potential launch as early as the first week of April, although delays during the rocket’s critical preflight processing and static fire test are about as likely as they were during the vehicle’s inaugural mission. If the rocket’s first launch and booster recoveries are fully successful, both side boosters (and perhaps the center core) could fly for a second time as few as two months later in June 2019.
A number of photos taken by Instagram users visiting Kennedy Space Center appear to indicate that SpaceX has more or less completed the reconfiguration of Pad 39A’s transporter/erector (T/E), modifying the base with additional hold-down clamps to account for three Falcon boosters instead of the usual one. Ten days after the successful launch of Falcon 9 B1051 in support of Crew Dragon’s first mission to orbit, it’s likely that additional work remains to ensure that 39A is fully refurbished and reconfigured for Falcon Heavy.
For the heavy-lift rocket’s commercial debut and second flight ever, SpaceX is likely to be exceptionally cautious and methodical in their preflight preparations. This is especially necessary due to the fact that Falcon Heavy Flight 2 differs dramatically from Falcon Heavy’s demo configuration, degrading the applicability of some aspects of the data gathered during the rocket’s largely successful test flight.
Most notably, all three first stage boosters will be Block 5 variants on their first flights, whereas Flight 1’s first stage featured two flight-proven Block 2 boosters (B1023 and B1025) and one new Block 3 booster (B1033). Additionally, the center core – B1033 – was lost during a landing anomaly that prevented the booster from reigniting its engine for a landing burn, cutting off another valuable source of data that would have served to better inform engineers on the performance of Falcon Heavy’s complex and previously unproven mechanical stage separation mechanisms.
Falcon 9 Block 5 is a fairly radical departure from the Block 2 and 3 variants SpaceX based Falcon Heavy’s initial design on. It’s possible that the rocket’s engineers were able to at least set up that design and manufacturing work on a safe path to forward compatibility, but it’s equally possible that so much work was focused on simply getting the vehicle past its launch debut that compatibility with Falcon 9 Block 4 and 5 was pushed well into the periphery. Considering the fact that it has now been more than a year since Falcon Heavy’s February 6th, 2018 debut, the latter eventuality offers a much better fit. Nevertheless, with a solid 13-14 additional months of redesign and testing complete, it seems that SpaceX is keen to get its super heavy-lift launch vehicle back on the horse, so to speak.
The specific changes made in Falcon 9 Block 4 is unclear aside from a general improvement in Merlin 1D and MVac performance, as well as significant upgrades to Falcon 9’s upper stage, likely focused on US military and NASA requirements for long-coast capabilities on unique mission profiles. Most significantly, Falcon 9 Block 5 transitioned the SpaceX rocket to a radically different primary thrust structure (also known as the octaweb), replacing welded assemblies with bolted assemblies wherever possible. This simultaneously allows for easier repairs and modifications, improves ease of manufacture, and increases the structure’s overall strength, a critical benefit for Falcon Heavy’s heavily-stressed center core. Meanwhile, Falcon 9 Block 5 moved from Full Thrust’s (Block 3/4) maximum 6800 kN (1,530,000 lbf) of thrust to more than 7600 kN (1,710,000 lbf), an increase of roughly 12%. Combined with Block 5’s focus on extreme reusability, SpaceX engineers and technicians likely had to do a huge amount of work to leap from Falcon Heavy Flight 1 to Flight 2.
Aside from the presence of both Falcon Heavy side boosters, both of which were spotted arriving in Florida by local observers, the first Block 5 Falcon Heavy center core also very likely arrived within the last few months, followed rapidly by can be assumed to be the mission’s fairing and Falcon upper stage. Falcon Heavy’s commercial debut will see the rocket attempt to place communications satellite Arabsat 6A – weighing around 6000 kg (13,200 lb) – into a high-energy geostationary orbit, either direct-to-GEO or a transfer (GTO) variety.
If all goes according to plan, SpaceX will attempt to turn around Falcon Heavy’s Block 5 side boosters (B1052 and B1053) for Falcon Heavy’s third launch – the USAF’s STP-2 mission – as few as 60-80 days later, June 2019. According to NASASpaceflight, STP-2 will fly with a new center core (presumed to be B1057) instead of reusing Arabsat 6A’s well-cooked B1055 booster.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
In a groundbreaking new report from Reuters, SpaceX is reportedly discussing merger possibilities with xAI ahead of the space exploration company’s plans to IPO later this year, in what would be a blockbuster move.
The outlet said it would combine rockets and Starlink satellites, as well as the X social media platform and AI project Grok under one roof. The report cites “a person briefed on the matter and two recent company filings seen by Reuters.”
Musk, nor SpaceX or xAI, have commented on the report, so, as of now, it is unconfirmed.
With that being said, the proposed merger would bring shares of xAI in exchange for shares of SpaceX. Both companies were registered in Nevada to expedite the transaction, according to the report.
On January 21, both entities were registered in Nevada. The report continues:
“One of them, a limited liability company, lists SpaceX and Bret Johnsen, the company’s chief financial officer, as managing members, while the other lists Johnsen as the company’s only officer, the filings show.”
The source also stated that some xAI executives could be given the option to receive cash in lieu of SpaceX stock. No agreement has been reached, nothing has been signed, and the timing and structure, as well as other important details, have not been finalized.
SpaceX is valued at $800 billion and is the most valuable privately held company, while xAI is valued at $230 billion as of November. SpaceX could be going public later this year, as Musk has said as recently as December that the company would offer its stock publicly.
The plans could help move along plans for large-scale data centers in space, something Musk has discussed on several occasions over the past few months.
At the World Economic Forum last week, Musk said:
“It’s a no-brainer for building solar-powered AI data centers in space, because as I mentioned, it’s also very cold in space. The net effect is that the lowest cost place to put AI will be space and that will be true within two to three years, three at the latest.”
He also said on X that “the most important thing in the next 3-4 years is data centers in space.”
If the report is true and the two companies end up coming together, it would not be the first time Musk’s companies have ended up coming together. He used Tesla stock to purchase SolarCity back in 2016. Last year, X became part of xAI in a share swap.

SpaceX Starship V3 gets launch date update from Elon Musk
The first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
Elon Musk has announced that SpaceX’s next Starship launch, Flight 12, is expected in about six weeks. This suggests that the first flight of Starship Version 3 and its new Raptor V3 engines could happen as early as March.
In a post on X, Elon Musk stated that the next Starship launch is in six weeks. He accompanied his announcement with a photo that seemed to have been taken when Starship’s upper stage was just about to separate from the Super Heavy Booster. Musk did not state whether SpaceX will attempt to catch the Super Heavy Booster during the upcoming flight.
The upcoming flight will mark the debut of Starship V3. The upgraded design includes the new Raptor V3 engine, which is expected to have nearly twice the thrust of the original Raptor 1, at a fraction of the cost and with significantly reduced weight. The Starship V3 platform is also expected to be optimized for manufacturability.
The Starship V3 Flight 12 launch timeline comes as SpaceX pursues an aggressive development cadence for the fully reusable launch system. Previous iterations of Starship have racked up a mixed but notable string of test flights, including multiple integrated flight tests in 2025.
Interestingly enough, SpaceX has teased an aggressive timeframe for Starship V3’s first flight. Way back in late November, SpaceX noted on X that it will be aiming to launch Starship V3’s maiden flight in the first quarter of 2026. This was despite setbacks like a structural anomaly on the first V3 booster during ground testing.
“Starship’s twelfth flight test remains targeted for the first quarter of 2026,” the company wrote in its post on X.
