SpaceX Falcon Heavy completes successful rehearsal, static fire pushed back due to bug in launch pad hardware
More than a decade after its 2005 public conception, SpaceX is closer than ever to the first launch Falcon Heavy, the company’s newest rocket. Earlier this afternoon, the vehicle was aiming for its first static fire test, in which all 27 of its engines would be ignited (nearly) simultaneously in order to test procedures and the rocket itself. This attempt was sadly scrubbed, but only after the vehicle apparently completed a successful wet dress rehearsal, which saw Falcon Heavy fully loaded with propellant. According to Orlando’s News 13, the attempt was scrubbed only after one of eight hold-down clamps showed signs of bugs.

While Falcon Heavy is not explicitly critical for SpaceX’s near-term launch business and its loftier future goals, the development and operation of such a massive launch vehicle will likely serve as a strong foundation as the company transitions more aggressively into the design, engineering, and manufacture of its still-larger BFR series of rocket boosters and upper stages. Falcon Heavy stands approximately as tall as Falcon 9 at around 70 m (230 ft), but features three times the thrust and a little less than three times the weight of SpaceX’s workhorse rocket. With 27 Merlin 1D engines to Falcon 9’s namesake nine, Falcon Heavy’s 22,800 kN (5,000,000 lbf) of thrust is a nearly inconceivably amount of power, equivalent to twenty Airbus A380 passenger jets at full throttle.
Why is Falcon Heavy important?
If SpaceX manages to pull off Falcon Heavy as a successful and reliable launch vehicle on the order of its reasonably successful Falcon 9, BFR may well be an easier vehicle to develop and operate, thanks to its single-core design. As Musk himself has discussed over the last year or so, the problem of safely and reliably distributing the thrust of Heavy’s side cores to the center core was unexpectedly difficult, as were the issues of igniting all 27 Merlin 1Ds and safely separating the side cores while in flight. Ultimately, the payload improvement (while in a fully reusable mode of operation) was quite small, particularly for the geostationary missions that make up essentially all prospective Falcon Heavy customer missions.
The additional complexity of recovery and refurbishing three separate Falcon 9 boosters almost simultaneously likely serves to only worsen the vehicle’s potential payoff, although the upcoming Block 5 iteration of Falcon 9 may partially improve the vehicle’s ease of operation. If Block 5 is indeed as reusable as SpaceX intends to make it, then a handful of Block 5 Falcon Heavy vehicles could presumably maintain a decent launch cadence for the vehicle without requiring costly and time-consuming shipping all over the continental US.

Nevertheless, the (hopefully successful) experience that will follow the launch and recovery operation of a super heavy-lift launch vehicle (SHLV) with ~30 first stage engines will be invaluable for SpaceX’s interplanetary goals. While BFR will be free of the complexity Falcon Heavy’s triple-core first stage added, it is still a massive vehicle that absolutely dwarfs anything SpaceX has attempted before. BFR in its 2017 iteration would mass around three times that of Falcon Heavy and feature 30 Raptor engines capable of approximately 53,000 kN (12,000,000 lbf) of thrust at liftoff, around 2.5x that of Heavy. Many, many other features mean that BFR and particularly BFS will be extraordinarily difficult to realize: BFS alone will be treading into truly unprecedented areas of spaceflight with the scale, longevity, and reusability it is intended to achieve while comfortably ferrying dozens of astronauts to and from Mars and the Moon.
However, the scale of BFR is equivalent to that of the famous Saturn V rocket that took astronauts to the Moon in the 1960s and 70s. In other words, while still dumbfoundingly massive and unprecedented in the modern era, rockets at the scale of BFR do in fact have a precedent of success, which lends the effort considerable plausibility, at least at proof-of-concept level. As of September 2017, Elon Musk suggested that SpaceX was aiming to begin construction of the first BFS (Big ____ Spaceship) by the end of Q2 2018, a truly Muskian deadline that probably wont hold. Still, if construction of the first prototype begins at any point in 2018, it will bode well for SpaceX’s aggressive timelines.

In the meantime, BFR’s precursor Falcon Heavy has effectively completed its first wet dress rehearsal, although the static fire attempt was scrubbed for the day. This is understandable for such a complex and untested vehicle, especially after SpaceX’s exceptionally quick modifications to Pad 39A. While unofficial, word is that an issue with one of the Transport/Erector/Launcher’s (TEL) eight separate launch clamps caused the scrub. Those launch clamps ensure that the massive vehicle would stay put during a static fire, and the status of those clamps would be especially important during such an unusually long static fire of such a powerful rocket.
Stay tuned for updates on SpaceX’s upcoming launches and Falcon Heavy’s next static fire attempt, likely within the next several days. The vehicle’s inaugural launch date is effectively up in the air until the static fire has been successfully completed, but as of yesterday SpaceX was understood to be targeting January 26th. Delays are to be expected.

Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.
“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.
The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.
In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.
However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.

Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.
The sheer scale of TERAFAB is going to be insane.
Elon said it wouldn’t be suitable for anywhere on Giga Texas property because it’s too big:
“We couldn’t possibly fit the Terafab on the GigaTexas campus. It will be far bigger than everything else combined there.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.

“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”
He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”
SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.
Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.
All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.
Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:

This flight intentionally had much higher acceleration to test how well the heat shield tiles would remain attached at high dynamic pressure.
Test was successful.

SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.
Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.
The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.

Just hours after Starship Flight 13 achieved a successful soft splashdown of its upper stage in the Indian Ocean on July 24, Elon Musk announced an ambitious next step for the company’s next launch of the rocket.
“Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on [the] next flight,” the SpaceX CEO posted on X on Friday.
That “next flight” is expected to be Flight 14. The plan involves returning the Starship upper stage, commonly called the “ship,” to the Starbase launch tower in Texas and catching it mid-air using the same mechanical “chopsticks” arms that have already proven themselves with the Super Heavy booster.

— Elon Musk (@elonmusk) July 25, 2026
A successful catch would mark the first time an orbital-class upper stage has been recovered this way, advancing SpaceX’s goal of full and rapid reusability for the entire vehicle.
SpaceX has already demonstrated the tower-catch technique multiple times with Super Heavy. The first successful catch came on Flight 5 in October 2024, when Booster 12 was plucked from the sky by the Mechazilla arms. Subsequent flights, including those involving Boosters 14 and 15, repeated the feat. Several of those recovered boosters were later inspected, refurbished, and flown again, proving the system’s viability for quick turnaround.

Traditional reusable rockets, such as SpaceX’s own Falcon 9 or Blue Origin’s New Shepard, land on legs either on land or droneships. Rocket Lab has recovered its small Electron first stages by helicopter, but those are far lighter vehicles.
SpaceX Starship just nailed something it’s never done before
The China Academy of Launch Vehicle Technology (CALT), a subsidiary of the China Aerospace Science and Technology Corp. (CASC), completed a catch of its booster on July 10. They are the only entity besides SpaceX to attempt and complete the feat.
Flight 13 provided encouraging data. The ship executed a controlled reentry, flipped, and soft-landed intact in the ocean after deploying Starlink satellites, offering the first clear post-splashdown views of an undamaged heat shield. The Super Heavy booster, meanwhile, experienced a harder splashdown in the Gulf of America.
Musk has previously stressed that ship catches would only follow multiple successful soft ocean landings to minimize risk of debris over land.
If Flight 14 succeeds, SpaceX would take a major stride toward routine, rapid reuse of both stages—critical for lowering launch costs and supporting ambitious plans for lunar and Mars missions. For now, teams are reviewing the Flight 13 data. Should everything check out, the next Starship flight could deliver one of the most spectacular recoveries in aerospace history.
