Elon Musk and SpaceX won’t be stopped along the road to Mars
If one is to take anything at all away from Elon Musk’s update to SpaceX’s planetary colonization strategy on September 29, it ought to be the tangible and undeniable progress the company has made with real, Mars-focused hardware development.
To take Musk at his word, the general atmosphere pervading the two relevant programs is one of extreme success and confidence. Raptor, the powerful methane-oxygen rocket engine intended to be the workhorse for any larger launch vehicle, has conducted dozens (42, to be specific) of successful hot fires at SpaceX’s McGregor, Texas testing facilities. These ranged from a handful of seconds all the way to 100 seconds in duration, and Musk made it explicitly clear that the only limiting factor to test duration was the size of the tanks of propellant available to fuel the engine. Of crucial importance is the fact that the engine being tested in Texas is a subscale prototype, and is not representative of the final engine. However, SpaceX has since shrunk the final target for operational Raptors, and this means that the current scale is not far off from the final thrust figure. The prototype Raptor is believed to have a thrust of approximately 1,000 kN (Kilonewtons), with slides from Musk’s 2017 presentation pointing to a full scale thrust of 1700 kN, far closer to becoming real than the 3,000 kN figure given at the 2016 IAC.

Possibly even more significant is the reported success SpaceX has had with the construction and stress testing of a full-scale carbon fiber liquid oxygen tank, which was tested to a very eventful destruction on Washington state’s Puget Sound. Fans closely followed this series of tests, but information was scarce and the general consensus was that the tank had failed unintentionally during those tests. The fact that Musk claimed that the 12 meter diameter tank was “successfully tested” at high pressures, as well as the confidence he expressed about a uniquely capable “carbon fiber matrix”, suggest that SpaceX have leaped over one of biggest potential hurdles of their larger vehicle plans. Carbon fiber propellant tanks have the potential to make rockets significantly lighter and thus more efficient, particularly if no internal liner of metal is needed to ensure the safety of those carbon fiber tanks. One might remember the difficulties SpaceX had with supercool liquid oxygen, culminating in the Amos-6 mishap that saw carbon fiber helium tanks clash with SpaceX’s then-new supercooled propellant procedures.

Through many challenging mistakes, SpaceX has learned the hard way that extra care must be taken when mixing carbon fiber and liquid oxygen. The telltale sign that SpaceX has, however, successfully learned from those mistakes can be found in the company’s aspiration to begin construction of the first BFR cargo ship as early as April of 2018, barely six months from today. Time will tell if they can maintain that aggressive schedule and launch two Mars-bound cargo ships in 2022. The company’s incontrovertible success with the development of Raptor engines and carbon fiber propellant tanks bode extremely well for the future of their planetary colonization efforts.

Samsung nears Tesla AI chip ramp with early approval at TX factory
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung has received temporary approval to begin limited operations at its semiconductor plant in Taylor, Texas.
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung clears early operations hurdle
As noted in a report from Korea JoongAng Daily, Samsung Electronics has secured temporary certificates of occupancy (TCOs) for a portion of its semiconductor facility in Taylor. This should allow the facility to start operations ahead of full completion later this year.
City officials confirmed that approximately 88,000 square feet of Samsung’s Fab 1 building has received temporary approval, with additional areas expected to follow. The overall timeline for permitting the remaining sections has not yet been finalized.
Samsung’s Taylor facility is expected to manufacture Tesla’s AI5 chips once mass production begins in the second half of the year. The facility is also expected to produce Tesla’s upcoming AI6 chips.
Tesla CEO Elon Musk recently stated that the design for AI5 is nearly complete, and the development of AI6 is already underway. Musk has previously outlined an aggressive roadmap targeting nine-month design cycles for successive generations of its AI chips.
Samsung’s U.S. expansion
Construction at the Taylor site remains on schedule. Reports indicate Samsung plans to begin testing extreme ultraviolet (EUV) lithography equipment next month, a critical step for producing advanced 2-nanometer semiconductors.
Samsung is expected to complete 6 million square feet of floor space at the site by the end of this year, with an additional 1 million square feet planned by 2028. The full campus spans more than 1,200 acres.
Beyond Tesla, Samsung Foundry is also pursuing additional U.S. customers as demand for AI and high-performance computing chips accelerates. Company executives have stated that Samsung is looking to achieve more than 130% growth in 2-nanometer chip orders this year.
One of Samsung’s biggest rivals, TSMC, is also looking to expand its footprint in the United States, with reports suggesting that the company is considering expanding its Arizona facility to as many as 11 total plants. TSMC is also expected to produce Tesla’s AI5 chips.

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.
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.
“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.

Elon Musk confirms SpaceX is not developing a phone
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.”
Not out of the question at some point. It would be a very different device than current phones. 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.”

— Elon Musk (@elonmusk) February 5, 2026
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.
SpaceX officially acquires xAI, merging rockets with AI expertise
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.
