SpaceX rolls first Starship booster hardware to launch site
While destined to remain on the ground, SpaceX has rolled Starship booster hardware to its Boca Chica, Texas launch pad for the first time.
Back in March, SpaceX completed the process of stacking Super Heavy booster number 1 (BN1), creating what amounted to the largest rocket booster ever assembled. Plans and designs ultimately changed during that several-month process, leading SpaceX to write off the first completed Starship booster structure as a “pathfinder” and scrap it before it could complete a single test. As a result, BN1 never made it to SpaceX’s nearby launch and test facilities and was unceremoniously cut into pieces days later.
Ten weeks after that development, SpaceX is well into the process of stacking its first flightworthy Super Heavy booster (BN2 or BN3) and has officially delivered the first real booster hardware to the launch site for crucial qualification testing.
While only a ‘test tank,’ BN2.1’s arrival at SpaceX’s South Texas launch facilities is an undeniable sign that the company has finally settled on some sort of firm design for Starship’s first-stage booster – at least enough for a custom test article to be worth the time, effort, and money to build and test. BN2.1 is the eighth custom test tank built by SpaceX in the last ~18 months but it’s the first such test article to center around hardware specific to Super Heavy.
Technically, thanks to the fact that Starship and Super Heavy are built out of the exact same steel rings, baffles, and stringers with almost identical production hardware, all past test tanks – and even full Starships – simultaneously mature large portions of Starship’s booster.
Super Heavy requires several unique parts and sections, though. Unlike Starship, which is designed to ultimately have six Raptor engines installed, the ship’s booster will have anywhere from 29 to 32 Raptors and have to withstand almost five times the mechanical stress. That necessitates a drastically different thrust structure for Super Heavy, as well as all additional structural elements to support the 20 Raptor engines – compared to three on Starship – that will mount to the interior wall of its skirt rings.
Beyond Super Heavy’s thrust puck, the booster also requires a much larger transfer tube to feed far more liquid methane through its oxygen tank, a custom dome to connect to that transfer tube, and a custom forward dome and ring section to support four vast grid fins.
BN2.1 is never going to (intentionally) fly and is just a single test tank, which rules out installing actual engines. Now routine, SpaceX’s solution to that challenge of qualifying new hardware without risking catastrophic pad damage has involved building short ‘test tanks’ that are then filled with nonexplosive liquid nitrogen (LN2) and mechanically stressed with hydraulic rams instead of actual engines. Thus far, that process has seemingly been successful time and time again and has helped SpaceX qualify new steel alloys, thinner skin, new welding techniques, and new ‘thrust puck’ designs for Starship.
SpaceX has also tested early full-scale prototypes with the same hydraulic ram systems as a further hedge against quality assurance or fluke design issues that might not have been caught with test tanks. Whether or not BN2.1 is successful, it’s safe to assume that SpaceX will put its first flightworthy Super Heavy booster through a similar thrust puck stress test before attempting wet dress rehearsals or static fires.
Wasting no time at all, SpaceX has already scheduled road closures for what is likely BN2.1’s first round of tests no earlier than (NET) 12pm to 8pm CDT (17:00-03:00 UTC) on Monday, June 7th, with backup windows on the 8th and 9th. Stay tuned to find out if Super Heavy’s thrust puck survives its first nine-engine thrust puck shuck.

SpaceX secures win as US labor board drops oversight case
The NLRB confirmed that it no longer has jurisdiction over SpaceX.
SpaceX scored a legal victory after the National Labor Relations Board (NLRB) decided to dismiss a case which accused the company of terminating engineers who were involved in an open letter against founder Elon Musk.
The NLRB confirmed that it no longer has jurisdiction over SpaceX. The update was initially shared by Bloomberg News, which cited a letter about the matter it reportedly reviewed.
In a letter to the former employees’ lawyers, the labor board stated that the affected employees were under the jurisdiction of the National Mediation Board (NMB), not the NLRB. As a result, the labor board stated that it was dismissing the case.
As per Danielle Pierce, a regional director of the agency, “the National Labor Relations Board lacks jurisdiction over the Employer and, therefore, I am dismissing your charge.”
The NMB typically oversees airlines and railroads. The NLRB, on the other hand, covers most private-sector employers, as well as manufacturers such as Boeing.
The former SpaceX engineers have argued that the private space company did not belong under the NMB’s jurisdiction because SpaceX only offers services to “hand-picked customers.”
In an opinion, however, the NMB stated that SpaceX was under its jurisdiction because “space transport includes air travel” to get to outer space. The mediation board also noted that anyone can contact SpaceX to secure its services.
SpaceX had previously challenged the NLRB’s authority in court, arguing that the agency’s structure was unconstitutional. Jennifer Abruzzo, the NLRB general counsel under former United States President Joe Biden, rejected SpaceX’s claims. Following Abruzzo’s termination under the Trump administration, however, SpaceX asked the labor board to reconsider its arguments.
SpaceX is not the only company that has challenged the constitutionality of the NLRB. Since SpaceX filed its legal challenge against the agency in 2024, other high-profile companies have followed suit. These include Amazon, which has filed similar cases that are now pending.

Tesla accuses IG Metall member of secretly recording Giga Berlin meeting
The union has denied the electric vehicle maker’s allegations.
Police seized the computer of an IG Metall member at Tesla Giga Berlin on Tuesday amid allegations that a works council meeting was secretly recorded.
The union has denied the electric vehicle maker’s allegations.
In a post on X, Gigafactory Berlin plant manager André Thierig stated that an external union representative from IG Metall attended a works council meeting and allegedly recorded the session. Thierig described the event as “truly beyond words.”
“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote in his post on X.
Police later confirmed to local news outlet rbb24 that officers did seize a computer belonging to an IG Metall member at the Giga Berlin site on Tuesday afternoon. Tesla stated that employees had contacted authorities after discovering the alleged recording.
IG Metall denied Tesla’s accusations, arguing that its representative did not record the meeting. The union alleged that Tesla’s claim was simply a tactic ahead of upcoming works council elections.
The next works council election at Giga Berlin is scheduled for March 2 to 4, 2026. The facility’s management had confirmed the dates to local news outlets. The official announcement marks the start of the election process and campaign period.
Approximately 11,000 employees are eligible to participate in the vote.
The previous works council election at the plant took place in 2024, and it was triggered by a notable increase in workforce size. Under German labor law, regular works council elections must be held every four years between March 1 and May 31.

Elon Musk’s xAI plants flag in Bellevue AI hotspot
The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.
Elon Musk’s artificial intelligence company xAI has leased a full floor at Lincoln Square South in downtown Bellevue, WA, as per city permit filings.
The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.
Public records indicate that xAI leased roughly 24,800 square feet in Lincoln Square South. The location was previously occupied by video game company Epic Games. Lincoln Square South is part of the Bellevue Collection, which is owned by Kemper Development Co.
The lease was first referenced in January by commercial real estate firm Broderick Group, which noted that an unnamed tenant had secured the space, as stated in a report from the Puget Sound Business Journal. Later filings identified xAI as the occupant for the space.
xAI has not publicly commented on the lease.
xAI hinted at plans to open an office in the Seattle area back in September, when the startup posted job openings with salaries ranging from $180,000 to $440,000. At the time, the company had narrowed its location search to cities on the Eastside but had not finalized a lease.
xAI’s Bellevue expansion comes as Musk continues consolidating his businesses. Last week, SpaceX acquired xAI in a deal that valued the artificial intelligence startup at $250 billion. SpaceX itself is now valued at roughly $1.25 trillion and is expected to pursue an initial public offering (IPO) later this year.
Musk already has a significant presence in the region through SpaceX, which employs about 2,000 workers locally. That initiative, however, is focused largely on Starlink satellite development.
Bellevue has increasingly become a center for artificial intelligence companies. OpenAI has expanded its local office footprint to nearly 300,000 square feet. Data infrastructure firms such as Crusoe and CoreWeave have also established offices downtown.
