SpaceX team spotted removing Block 5 landing legs prior to teardown analysis
Teslarati photographer Tom Cross has captured SpaceX technicians removing the landing legs from the first Falcon 9 Block 5 booster, signaling that the end of recovery operations are near.
Of note, it appears that SpaceX chose to conduct this recovery much like previous ones by removing the rocket’s legs instead of retracting them, a feature of the Block 5 upgrade prominently noted by CEO Elon Musk and other company officials. A brief time-lapse shows workers carefully removing the legs in a well-worn ballet of heavy machinery, skirting around the massive rocket with expertise developed over the better part of two years of sea and land recoveries of Falcon 9 and Falcon Heavy boosters.
There are a number of possible reasons for SpaceX choosing to remove B1046’s landing legs the ‘old-fashioned’ way, most relating to the fact that this particular booster is a critical pathfinder for the entire future of Falcon 9 Block 5. Musk described this attitude in a lengthy and detailed prelaunch briefing:
We are going to be very rigorous in taking this rocket apart and confirming our design assumptions to be confident that it is indeed able to be reused without being taken apart. Ironically, we need to take it apart to confirm that it does not need to be taken apart.
Both COO Shotwell and Musk have briefly discussed the new functionality of the upgraded legs in the past few weeks, indicating that they are capable of being rapidly and repeatedly stowed without being removed from the rocket, whereas all past booster reuse has required the slow removable and equally slow reattachment of landing legs, assuming Block 3 and 4 boosters even reuse their same landing legs. At a minimum, Musk’s above comment already makes it clear that SpaceX has no plans to reuse this booster immediately, instead conducting an extremely thorough teardown analysis to verify that wear and tear from high-speed atmospheric reentry is within an acceptable range.

Equally plausible, choosing to remove B1046’s landing legs instead of testing the new retraction mechanisms may better preserve the leg hardware in its post-landing state, providing engineers and technicians cleaner and more representative data. One final obvious possibility is that the process of flight-testing new Block 5 leg hardware caused damage or led to some off-nominal telemetry and other visible faults, thus preventing them from retracting.
Because the next Block 5 booster (B1047) is likely nearing its own debut after a thorough round of testing in Texas, captured by an aerial photographer, SpaceX may be pushing hard to complete its post-landing analysis of B1046 as quickly as possible to make way for the imminent launches of several new boosters. If the company hopes to maintain its impressive 2018 flight rate of one launch every two weeks throughout the rest of the year, they will need to refly Block 5 boosters at least 10 times – the last flight-proven commercial Block 4 launch (CRS-15) is currently scheduled for early July, leaving roughly half of all 2018’s upcoming launches manifested on Block 5 Falcon 9/Heavy rockets. Falcon Heavy’s second launch has in fact been pushed back by several months per The Planetary Society, indicating that the construction of the first Block 5 center booster has taken a back seat to the more pressing concerns of Falcon 9 Block 5 boosters, upper stages, and fairings needed to avoid additional customer launch delays.

Regardless, the first successful and nearly-complete recovery of a Falcon 9 Block 5 booster marks a huge milestone for SpaceX. So long as the imminent teardown analysis does not reveal anything especially unexpected, the rocket company is quickly closing in on true rapid reuse with Octagrabber/Roomba’s steady routinization of robotic rocket saving, yet another intact fairing half recovery, and the good condition of B1046 after a relatively hot reentry and landing.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
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 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.
