SpaceX preps Starship, Super Heavy for another week of Raptor testing
SpaceX continues to work around the clock to prepare its latest Starship and Super Heavy booster prototypes for another week of testing – likely focused on firing up the Raptor engines installed on each vehicle.
Known as Booster 7 and Ship 24, SpaceX has been slowly testing both prototypes for approximately four months, beginning in April and May, respectively. Only in early August did the company cautiously begin attempting to ignite their Raptor engines as part of a process known as static fire testing – by far the most difficult and important part of qualifying both vehicles for flight.
Thanks to progress made in 2021, SpaceX already has significant experience testing an earlier orbital-class Starship prototype on the ground, but the process of testing Ship 24 is still fresh and unfamiliar for a number of reasons. For Booster 7, the challenges are even greater.
On top of major design changes made to Starship and Super Heavy over the last year as SpaceX continues to refine the rocket, the company also developed a substantially different version of its Raptor engine. Compared to Raptor V1, Raptor V2 almost looks like a new engine and can produce around 25% more thrust (230 tons versus 185 tons). SpaceX has also tweaked how the engine operates, particularly around startup and shutdown, further weakening the value of past experience testing Raptor V1 and V1.5 engines on Ship 20 and Boosters 3 and 4.
In other words, with Ship 24 and Booster 7 engine testing, it’s possible that SpaceX is effectively starting from scratch. Many aspects of testing – propellant conditioning, thermal characteristics, tanking, detanking, certain test stands – are likely mostly unchanged, but almost every aspect of a rocket is affected by its engines.
Before SpaceX began testing Raptor V2 engines on Starship and booster prototypes, it wasn’t clear if the changes between V1.5 and V2 would invalidate a lot of prior testing. After the start of Booster 7 and Ship 24 static fire testing, it’s now clear that a lot of that earlier work has to be redone. It’s also clear that despite some of the simplifications in Raptor V2’s design, operating the engine on Starship and Super Heavy is much harder get get right.
Since mid-July, SpaceX has completed around 15-20 ‘spin-prime’ tests between Ship 24 and Booster 7 – more of that kind of test than any other prototype in the history of Starbase has performed. Spin-prime tests flow high-pressure gas through Raptor’s pumps to spin them up without igniting anything. It’s unclear why so many of those tests are being done, what SpaceX is gaining from it, or why the company appears to have completely stopped conducting preburner tests (a more life-like spin-prime with partial combustion).
Regardless, eight weeks after the start of engine testing, Booster 7 has only performed three static fires (two with one engine, one with a max of three or four engines), and Ship 24 has only completed one static fire with two engines. Before either vehicle can be considered ready for flight, a day that could easily never come, each will likely need to conduct multiple successful static fires with all of their Raptor engines (6 on S24 and 33 on B7).
If the pace of Booster 7 testing doesn’t change, the vehicle could be months away from a full 33-engine static fire attempt – perhaps the single most important and uncertain test standing between SpaceX and Starship’s first orbital launch attempt. Ship 24’s path to flight readiness should be simpler, but it appears to be struggling almost as much.
According to CEO Elon Musk, “an intense effort is underway” to ensure that Super Heavy B7’s Raptor engines are well contained during anomalies, so that one engine violently failing won’t damage or destroy the booster, other engines, or the launch pad. That could certainly complicate the process of testing Booster 7, and it’s likely that SpaceX is taking some of the same actions to protect Ship 24.
In early September, after a partially successful Booster 7 static fire (its first multi-engine test) and numerous additional Ship 24 tests that failed to achieve ignition, SpaceX replaced engines on both vehicles. Booster 7 had one of 13 Raptor Center engines swapped out, while Ship 24 had one of its three Raptor Vacuum engines replaced.
On September 5th, SpaceX distributed a safety alert to Boca Chica’s few remaining residents, confirming that it wants to restart testing as early as Tuesday, September 6th. Especially as of late, that alert guarantees nothing, but it does at least open the door for SpaceX if Ship 24, Booster 7, and the positions of the stars happen to be in the right mood between 8am and 8pm CDT. Additional opportunities are available on September 7th, 8th, 9th, and 12th.

SpaceX just cleared a key FCC hurdle in its fight with Verizon and AT&T
The FCC accepted SpaceX’s bid for Grain’s 800 MHz spectrum, opening review for Starlink Mobile.
The Federal Communications Commission has formally opened its review of SpaceX’s plan to buy a nationwide block of 800 MHz spectrum from Grain Management, moving Starlink Mobile one step closer to operating as a full U.S. wireless carrier.
In a public notice issued Tuesday, the FCC’s Wireless Telecommunications Bureau said it accepted for filing the applications to transfer control of two Grain license companies, Prism License Co. 1 and Prism License Co. 2, to Starlink Spectrum Holdings, a wholly owned SpaceX subsidiary. The deal covers 546 paired licenses across 3,224 counties, reaching roughly 100% of the U.S. population in all 50 states, Washington, D.C., Puerto Rico and the U.S. Virgin Islands. The proceeding sits under WT Docket No. 26-313.
Acceptance is not approval. It means the applications cleared an initial review and the public comment window is now open. Comments and petitions to deny are due December 1, and oppositions are due December 8. The bureau also said the conditions attached to Grain’s July purchase of the licenses from T-Mobile, which require rapid buildout for terrestrial and direct to device service, would carry over to SpaceX if the transfer is approved.
SpaceX announced the agreement on October 8, saying the new airwaves would let Starlink Mobile’s signal reach phones inside buildings, something its 2 GHz spectrum from EchoStar cannot do as well. The portfolio includes up to 14 MHz of paired spectrum in the 817 to 824 MHz and 862 to 869 MHz bands, which most existing phones already support. Elon Musk called it “the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America.”
According to the filing, SpaceX would hold up to 89 MHz of total spectrum in any given market after the deal closes, including up to 14 MHz below 1 GHz. That is far under the 385 MHz threshold the FCC uses to flag a transaction for closer competitive scrutiny, and well short of the roughly 300 MHz each of AT&T, Verizon and T-Mobile holds.
Tuesday’s notice does not decide how SpaceX can use the spectrum from orbit. A separate application SpaceX filed on October 27 seeking authority to provide supplemental coverage from space on the same frequencies, along with related waiver requests, is still pending before the commission.
The ground network is already taking shape. Last week, SpaceX picked Qualcomm to supply radios, baseband units and software for a nationwide 5G build, with deployment across tens of thousands of U.S. cell sites starting in 2027. The FCC also voted on October 29 to advance a proposal opening another 482 MHz to direct to device service, though AT&T, Verizon and T-Mobile hacritive pushed to strip nearly 300 MHz from it. SpaceX President Gwynne Shotwell has said service on SpaceX’s own airwaves is targeted for early 2028.
A Tesla upfitter has offered to take over Cybertruck lines from the company in a last-ditch effort to save the all-electric pickup from being completely canceled in the middle of 2027.
Unplugged Performance, the Hawthorne, California-based Tesla aftermarket specialist, has publicly offered to take over Cybertruck production from Tesla, funding the effort “through a consortium of investors.”
An open offer to Tesla: We fully support putting Cybercab first, and we’d be glad to take the Cybertruck line off your hands.
We’d fund it with a consortium of investors and run it at no cost to Tesla’s floor space, headcount, or focus. All of that goes to Cybercab. Cybercab gets first call on battery cells too. We’ll wait our turn.
Tesla gains incremental profit: a license fee, plus FSD and Robotaxi network revenues on every vehicle built.
We’d build the Cybertruck, a three-row CyberSUV, and an unmanned CyberCargo hauler. More autonomous miles, across every surface of this planet and beyond.

The proposal comes as Tesla prioritizes its Cybercab Robotaxi program and prepares to wind down Cybertruck assembly at Gigafactory Texas around mid-2027.
Founded in 2013 by Ben Schaffer and located adjacent to Tesla’s Design Studio and SpaceX, Unplugged Performance has become a leading provider of premium upgrades for Tesla vehicles, including extensive Cybertruck packages under its UP INVINCIBLE line.
Through its UP.FIT division, the company has also developed purpose-built police and fleet versions of the Cybertruck, including deliveries to agencies such as the Las Vegas Metropolitan Police Department.
In an X post on Tuesday, Unplugged said:

The arrangement would free Tesla resources and manufacturing capacity for Cybercab while allowing continued production of the stainless-steel pickup and expanded variants. Unplugged Performance indicated it would wait for battery cells after Cybercab needs are met and would generate ongoing revenue for Tesla through licensing and software/network services on the vehicles it produces.
Following strong initial interest, Unplugged Performance posted a follow-up inviting potential investors and strategic partners to email cyber@unpluggedperformance.com. The company clarified that the outreach is solely to gauge interest and does not constitute an offer to sell securities or acceptance of funds at this stage.
The proposal arrives shortly after Elon Musk indicated that Cybertruck production in Texas would be phased out by roughly the middle of 2027 to expand Cybercab output.
Whether Tesla engages with the offer remains to be seen, but the public overture highlights both the aftermarket specialist’s deep experience with the Cybertruck platform and the growing focus on autonomy within Tesla’s manufacturing plans.
Elon Musk said the Tesla Cybercab will perform “a majority of all passenger miles” where it is allowed to operate and that point is “obvious to anyone with eyes and a brain.”
Musk used the point to double down on the company’s decision to ax the cult-favorite Cybertruck, as its production space will be removed and transitioned into additional Cybercab lines. The move has catalyzed a polarizing conversation on whether its right or wrong.
Whatever side you are on — it’s happening.
Dodge ended the Viper.
Audi retired the R8.
Mitsubishi said goodbye to the Lancer Evo.
Ford bid farewell to the Bronco (at one point).
Chevrolet sunset the Camaro.Tesla is ending the Cybertruck. I’m pissed. I’m upset.
Fans of those five automakers mentioned did the same thing. It happens. It sucks. I don’t like it.
But I still love Tesla. I love my Model Y. I hoped to be in a Cybertruck in a little under two years.
I won’t be. But I still won’t put my family in anything else. Too safe. Too advanced. Too much better than everything else.

Regardless, Musk seems to be getting to the point that he is done talking about the choice. At some point, you have to think that this was truly a difficult decision for him and the company as well, and this is not something he took lightly. In fact, he’s probably a little bit disappointed with it, too.
But the point remains that the Cybertruck is gone. Musk’s focus is purely on developing an autonomous platform that the world will utilize for transportation, and he’s telling you that anyone “with eyes and a brain” can see it:
@PalmerLuckey @carlhancock Cybercab will do a majority of all passenger miles in any jurisdiction where it is not prohibited by law.
Obvious to anyone with eyes and a brain.

Tesla is betting that all of its passengers in the future will be okay with not owning their own personal cars and will be fine with ride-hailing for the rest of their lives. Every dinner, every errand, every trip to the airport and transportation thereafter, will all be operated by ride-sharing, and in Tesla’s perfect world, it will happen in a Cybercab.
As of now, Cybercab is only active in Austin, but it has been spotted all over the country with a driver behind the wheel in those prototypes. In Austin, the car has no steering wheel or pedals for people to control the vehicle.
The Cybertruck dilemma is one that has truly come across the entire Tesla community and while it seems to be a great idea to keep it because people love it, the business side of things is steering Musk and Tesla in another direction.
