SpaceX wins NASA funds to build and test Starship’s orbital refueling technology
On September 27th, NASA announced a new round of Tipping Point funding worth a total of $43.2M that will be dispersed among 14 separate companies, all focused on advancing “important technologies necessary for sustained exploration of the Moon and Mars.”
Aside from Blue Origin and a dozen others, SpaceX received $3M to work with NASA’s Marshall Space Flight Center (MSFC) to build and test “cryogenic fluid couplers”, a type of nozzle Starship will need to refuel in orbit.
Noted multiple times over the years (and in recent days) by both SpaceX and CEO Elon Musk, an extremely robust and reliable method of orbital refueling is essential to the success of Starship’s current designed – perhaps more so than any other single aspect of the next-generation launch vehicle. Although Starship-Super Heavy will likely offer respectable performance in single-launch mode, the implicit need to recover and reuse both booster and spacecraft takes a big chunk out of the rocket’s potential capabilities.

Much like Falcon 9 and Heavy must sacrifice performance for booster landings, Super Heavy will also need to retain some amount of propellant for its boostback and landing burns. However, while just 1 kg of orbital payload is lost for every ~5-10 kg of extra hardware and propellant on the booster, things are far more consequential when discussing orbital stage reusability. Every single kilogram of hardware and propellant meant for Starship recovery and reuse will result in a 1:1 reduction in payload capacity. This becomes highly consequential when recovering the spacecraft involves the addition of something like 100-200 metric tons worth of wings, fins, heat shield tiles, batteries, propellant, and more.
As such, SpaceX is faced with a conundrum: to make spaceflight truly cheap, full reusability is a necessity, but full reusability almost fundamentally constrains the resultant rocket’s performance and utility. SpaceX’s solution: prolific orbital refueling on the order of anywhere from 1-10+ dedicated tanker launches for every Starship launch. By refueling in Earth orbit, be it low Earth orbit or something much more eccentric, Starship can be extremely reusable while still offering performance that even a similarly-sized, fully-expendable rocket couldn’t begin to compete with.
Although the theory behind SpaceX’s strategy is undeniably sound, the fact remains that orbital refueling has never been tested anywhere close to the scale, speed, or reliability Starship will need for numerous in-orbit refuelings to be a practical solution. Assuming SpaceX uses every ounce of Starship and Super Heavy’s performance for each tanker launch to low Earth orbit (LEO), Starship will have to be able to repeatedly and rapidly transfer at least 150 metric tons (330,000 lb) of liquid oxygen and methane in microgravity conditions.

Without Earth’s gravity and the force of multiple Raptor engines to help things along, it could be quite a challenge to transfer hundreds of tons of propellant in a reasonable timeframe while in orbit. In fact, SpaceX already has Space Act Agreements in place with NASA centers to mature orbital propellant transfer technology. The September 27th award simply continues that relationship, although this particular case involves the first direct funding from NASA – meant to help SpaceX over the “tipping point”.
This time around, SpaceX will work directly with NASA MSFC to build and test actual prototypes of the nozzles (“cryogenic fluid couplers”) Starship will use to mate and refuel in orbit.
“SpaceX will collaborate with NASA’s Marshall Space Flight Center in Huntsville, Alabama, to develop and test coupler prototypes – or nozzles – for refueling spacecraft such as the company’s Starship vehicle. A cryogenic fluid coupler for large-scale in-space propellant transfer is an important technology to aid sustained exploration efforts on the Moon and Mars.”

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.
