Shortly after Teslarati reported that the first operationalized Raptor had shipped to McGregor, Texas for its first full-scale static fire tests, SpaceX CEO Elon Musk took to Twitter to post the first official photos of the “radically redesigned” engine preparing for its critical debut test fire in Texas.

Designed with extreme reliability, efficiency, and reusability in mind, the Raptor seen in Musk’s photos is rated for just shy of 2.5 times the thrust of Merlin 1D at 200 tons (450,000 lbf) and has been commonized across both stages of BFR (Starship and Super Heavy) to spread out development costs and speed up the next-generation rocket’s orbital launch debut.

Aside from revealing some impressive photos of the first upgraded Raptor preparing for a static fire test, Musk went into a bit more detail on the future of the engine and its probable development path, describing Raptor in its current iteration as a sort of compromise between achieving nominal performance and minimizing the cost and timescale to arrive at a flight-ready engine. Currently stationed at SpaceX’s McGregor, Texas development and testing facilities, Raptor appears to feature an expansion ratio somewhere in between Merlin 1D (optimized for sea-level) and MVac (optimized for vacuum).

This increases the stress on the nozzle during ignition and operation at normal atmospheric pressures but it also improves engine efficiency once Starship (or Super Heavy) rises above the thickest parts of Earth’s atmosphere, even if a medium-expansion nozzle still can’t touch the performance of a giant vacuum-optimized bell like those used by MVac. As such, BFR in its earliest iterations will be significantly less capable than a fully-optimized version of the rocket when it comes to high-energy Earth/lunar orbits and interplanetary trajectories, a challenge that can at least initially be hurdled by accepting much lower nominal payload capabilities and relying on brute-force performance, much like Falcon 9 and Heavy.

Assuming the first hot-fire tests of the full-scale, operationalized Raptors go well, three of the next-gen engines could support the first hop tests of a full-scale Starship prototype sometime in the next few months, potentially as early as late-February or March. Musk also reiterated that Starship’s complimentary booster – known as Super Heavy and set to begin initial prototype assembly as early as April – will feature 31 Raptor engines capable of producing upwards of 12.4 million pounds of thrust (62,000 kN) at liftoff. However, Musk indicated that the sheer value of 31 advanced Raptor engines also means that the first Super Heavy flights may only feature a partial complement of engines in case the vast booster experiences a failure, far from uncommon during the first few launches of a new rocket.

Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills. 

The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.

Texas’ Cybertruck V2G program

In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.

During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.

The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.

Powershare Grid Support

To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.

Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.

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.
