SpaceX has rolled Falcon 9 and Crew Dragon out to Pad 39A for the second time ever in preparation for a full wet dress rehearsal (WDR) and static fire – no earlier than Jan. 23 – of booster B1051’s nine Merlin 1D engines, preparing for an orbital launch attempt that slipped from NET Feb. 9 to Feb. 16 earlier this week.

While this milestone is important for myriad other reasons, it happens to be exceptionally unique thanks to one particularly surprising feature: Falcon 9 rolled out for its static fire with Crew Dragon (the rocket’s payload) still attached. This will be the first time in more than 28 months – since Amos-6, the last catastrophic Falcon 9 failure – that SpaceX has performed its routine on-pad static fire with a valuable payload attached to the rocket.

On September 1st, 2016, a SpaceX Falcon 9 experienced the rocket family’s second catastrophic failure ever when supercool liquid oxygen froze around a COPV’s carbon fiber wrappings, expanding just enough to breach the ultra-high-pressure vessel. Falcon 9 and its ~$200M Amos-6 satellite payload were completely destroyed, while Launch Complex 40 (LC-40) suffered tens of millions of dollars of damage that would effectively require it to be completely rebuilt over the course of more than a year.

After Amos-6, SpaceX immediately halted the practice of including customer payloads on Falcon 9 during static fires, used to save 24-48 hours of time between static fire and launch. SpaceX nevertheless retained the option if customers were to explicitly request it, otherwise wisely concluding (likely with more than a little encouragement from insurance companies) that expediting schedules by a few dozen hours was not worth the entirely unnecessary risk to satellite payloads that often cost hundreds of millions of dollars and take years to build.

Given that SpaceX has stuck to that practice for all 38 Falcon 9 launches it has performed between Amos-6 and the present day, it seems all but guaranteed that the first orbit-ready Crew Dragon’s presence on Falcon 9 during its static fire has been done only at the specific request of the launch customer – in this case, NASA. It’s probably not hyperbolic to argue that Demo-1’s (DM-1) Crew Dragon is the most valuable, important, expensive, and irreplaceable spacecraft SpaceX has ever attempted to launch, having likely spent millions of work hours building, changing, refining, and testing it to meet NASA’s exacting and sometimes absurd requirements.

If Falcon 9 B1051 were to fail with Crew Dragon atop it during its Pad 39A static fire, it might be possible for the DM-2’s Crew Dragon to be completed and modified for an uncrewed test flight with just six months of delay, assuming Falcon 9’s mode of failure could be investigated and repaired to NASA’s satisfaction. However, the destruction of the DM-1 capsule and trunk could almost indefinitely delay SpaceX’s first crewed launch, dependent upon an inflight-abort test that is supposed to use the refurbished DM-1 capsule, while the Crew Dragon currently supposed to launch after DM-2 is unlikely to be ready before August or September 2019.

 

Ultimately, NASA likely requested that Crew Dragon remain atop Falcon 9 for this static fire out of some desire for a full-fidelity test environment and complement of data. There is perhaps a very limited chance that Crew Dragon will be fully fueled with hydrazine (MMH/NTO) and have its launch escape system (LES) active and ready to go in the event of a rocket failure.

Why they deemed the immense potential risk to be worthwhile is far less clear. Whether it is being done out of complacency or a desire for expediency or ultra-realistic test data, the risk is the same. In theory, Falcon 9 has been tested extensively and should operate perfectly, just as expected. So was Amos-6’s Falcon 9.

Elon Musk

Musk’s massive Terafab project will get final location soon

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.

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.”

Elon Musk reveals SpaceX performed secret Starship test on Flight 13

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:

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.

SpaceX wants to catch Starship for launch 14, Elon Musk says

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.

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.
