SpaceX’s Starship Mk1 rocket already has three Raptors installed, says Elon Musk
In a few late-night tweets, SpaceX CEO Elon Musk offered a rare view inside the company’s Boca Chica Starship fabrication building and revealed that technicians had already installed all three Raptor engines on Starship Mk1.
SpaceX is in the midst of a frenetic few weeks of activity as technicians and engineers – some likely flown in from Florida – work around the clock to ready Starship Mk1 for its first flight tests. Musk is also scheduled to present an official update on Starship’s latest design on September 28th and likely wants to have a complete Starship (or nearly so) as an imposing backdrop for the media event.

The news that SpaceX has already installed all three Raptor engines on Starship Mk1 comes as a surprise, an exceedingly rare instance thanks to near-continuous coverage provided by several local residents and 24/7 livestreams. On September 22nd, at least one Raptor engine was spotted arriving in Boca Chica, but no onlookers noticed engine installation operations.
Capable of producing 600+ metric tons (1.3M lbf) of thrust, those three Raptors were attached to a custom-fabricated thrust structure that was installed inside Starship Mk1 on August 14th, barely a month ago. There’s a chance that one or several of the Raptors installed are nonfunctional spares, but it’s likely that the engines installed are ready for flight and have completed static fires in McGregor, Texas. As such, they could very well be the engines that will power Starship’s inaugural flight tests, the first of which will involve a suborbital launch to an altitude of more than 20 km (12.5 mi).
Musk says that Starship Mk1’s three segments could be stacked atop each other as early as Wednesday, September 25th, also implying that the spacecraft prototype’s nose section should be fully outfitted with batteries, header tanks (small propellant tanks), its own actuating fins, and more in the next 2-3 days.
Additionally, Musk published a brief video inside SpaceX’s recently-completed Boca Chica Starship fabrication building, the only semi-permanent building the company has built at its South Texas facilities. Featuring an abstract series of mirror-like steel panels that created a bit of a house-of-mirrors effect, Musk says the items pictured will be combined to form Starship Mk1 wing hinges and raceways, an external tunnel used for plumbing and cable routing.
SpaceX installed both of Starship Mk1’s aft wings/flaps over a 48 hour period, wrapping up the basic mechanical integration on September 22nd. Work has started on the prototype’s raceway and the frames of the first two wing hinge covers were spotted on Friday. As of midnight local time on September 23rd, SpaceX technicians were welding propellant feed lines to the outside of Starship’s tank section and installing the rocket’s header tanks – small secondary propellant tanks – inside its pointed nose section.

Anti-Tesla union leader ditches X, urges use of Threads instead
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.Â
Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Anti-Tesla union leader exits X
In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.
“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.
Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant.Â
“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.
IF Metall sees Threads as an X alternative
After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.
Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.
“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.
Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.
Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.
Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.
Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.

A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.
Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.
Tesla has added a notable improvement to its Dashcam feature after complaints from owners have pushed the company to make a drastic change.
Perhaps one of the biggest frustrations that Tesla owners have communicated regarding the Dashcam feature is the lack of ability to retain any more than 60 minutes of driving footage before it is overwritten.
It does not matter what size USB jump drive is plugged into the vehicle. 60 minutes is all it will hold until new footage takes over the old. This can cause some issues, especially if you were saving an impressive clip of Full Self-Driving or an incident on the road, which could be lost if new footage was recorded.
This has now been changed, as Tesla has shown in the Release Notes for an upcoming Software Update in China. It will likely expand to the U.S. market in the coming weeks, and was first noticed by NotaTeslaApp.
The release notes state:
“Dashcam Dynamic Recording Duration – The dashcam dynamically adjusts the recording duration based on the available storage capacity of the connected USB drive. For example, with a 128 GB USB drive, the maximum recording duration is approximately 3 hours; with a 1 TB or larger USB drive, it can reach up to 24 hours. This ensures that as much video as possible is retained for review before it gets overwritten.”
Tesla Adds Dynamic Recording
Instead of having a 60-minute cap, the new system will now go off the memory in the USB drive. This means with:
- 128 GB Jump Drive – Up to Three Hours of Rolling Footage
- 1TB Jump Drive – Up to 24 Hours of Rolling Footage
This is dependent on the amount of storage available on the jump drive, meaning that if there are other things saved on it, it will take away from the amount of footage that can be retained.
While the feature is just now making its way to employees in China, it will likely be at least several weeks before it makes its way to the U.S., but owners should definitely expect it in the coming months.
It will be a welcome feature, especially as there will now be more customization to the number of clips and their duration that can be stored.
