SpaceX President explains termination of employees behind open letter criticizing Elon Musk’s tweets
Recently, news broke that some SpaceX employees have written an open letter criticizing CEO Elon Musk’s behavior on Twitter. The employees have been terminated by the private space firm, with SpaceX President Gwynne Shotwell explaining the rationale behind the company’s decision.
The open letter argued that SpaceX is not living up its “No Asshole” and zero-tolerance sexual harassment policies due to Elon Musk’s behavior. The open letter demanded that SpaceX should “publicly address and condemn Elon’s harmful Twitter behavior,” among others. “Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks,” the letter read.
In her letter to SpaceX employees, Shotwell clarified that the people behind the open letter had been terminated. She noted that SpaceX had received complaints from several employees who complained about the open letter because the initiative made them feel “uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views.”
Shotwell also highlighted that the letter interfered with workers’ ability to focus on their work, especially amidst SpaceX’s busy schedule. “We have too much critical work to accomplish and no need for this kind of overreaching activism — our current leadership team is more dedicated to ensuring we have a great and ever-improving work environment than any I have seen in my 35-years career,” she wrote.
Following is Shotwell’s letter to SpaceX employees about the matter:
You may have received an unsolicited request from a small group of SpaceX employees for your signature on an “open letter” yesterday and your participation in a related survey. Based on diverse employee feedback, this has upset many. That is, the letter, solicitations and general process made employees feel uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views.
Employees also complained that it interfered with their ability to focus on and do their work. We have 3 launches within 37 hours for critical satellites this weekend, we have to support the astronauts we delivered to the ISS and get cargo Dragon back to the flight-ready, and after receiving environmental approval early this week, we are on the cusp of the first orbital launch attempt of Starship. We have too much critical work to accomplish and no need for this kind of overreaching activism — our current leadership team is more dedicated to ensuring we have a great and ever-improving work environment than any I have seen in my 35-years career.
We solicit and expect our employees to report all concerns to their leadership, senior management, HR, or Legal. But blanketing thousands of people across the company with repeated unsolicited emails and asking them to sign letters and fill out unsponsored surveys during the work day is unacceptable, goes against our documented handbook policy, and does not show the strong judgement needed to work in this very challenging space transportation sector. We performed an investigation and have terminated a number of employees involved.
I am sorry for this distraction. Please stay focused on the SpaceX mission, and use your time at work to do your best work. This is how we will get to Mars.
The open letter of SpaceX employees about Elon Musk’s behavior can be viewed below.
An open letter to the Executives of SpaceX,
In light of recent allegations against our CEO and his public disparagement of the situation, we would like to deliver feedback on how these events affect our company’s reputation, and through it, our mission. Employees across the spectra of gender, ethnicity, seniority, and technical roles have collaborated on this letter. We feel it is imperative to maintain honest and open dialogue with each other to effectively reach our company’s primary goals together: making SpaceX a great place to work for all, and making humans a multiplanetary species.
As SpaceX employees we are expected to challenge established processes, rapidly innovate to solve complex problems as a team, and use failures as learning opportunities. Commitment to these ideals is fundamental to our identity and is core to how we have redefined our industry. But for all our technical achievements, SpaceX fails to apply these principles to the promotion of diversity, equity, and inclusion with equal priority across the company, resulting in a workplace culture that remains firmly rooted in the status quo.
Individuals and groups of employees at SpaceX have spent significant effort beyond their technical scope to make the company a more inclusive space via conference recruiting, open forums, feedback to leadership, outreach, and more. However, we feel an unequal burden to carry this effort as the company has not applied appropriate urgency and resources to the problem in a manner consistent with our approach to critical path technical projects. To be clear: recent events are not isolated incidents; they are emblematic of a wider culture that underserves many of the people who enable SpaceX’s extraordinary accomplishments. As industry leaders, we bear unique responsibility to address this.
Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks. As our CEO and most prominent spokesperson, Elon is seen as the face of SpaceX—every Tweet that Elon sends is a de facto public statement by the company. It is critical to make clear to our teams and to our potential talent pool that his messaging does not reflect our work, our mission, or our values.
SpaceX’s current systems and culture do not live up to its stated values, as many employees continue to experience unequal enforcement of our oft-repeated “No Asshole” and “Zero Tolerance” policies. This must change. As a starting point, we are putting forth the following categories of action items, the specifics of which we would like to discuss in person with the executive team within a month:
Publicly address and condemn Elon’s harmful Twitter behavior. SpaceX must swiftly and explicitly separate itself from Elon’s personal brand.
Hold all leadership equally accountable to making SpaceX a great place to work for everyone. Apply a critical eye to issues that prevent employees from fully performing their jobs and meeting their potential, pursuing specific and enduring actions that are well resourced, transparent, and treated with the same rigor and urgency as establishing flight rationale after a hardware anomaly.
Define and uniformly respond to all forms of unacceptable behavior. Clearly define what exactly is intended by SpaceX’s “no-asshole” and “zero tolerance” policies and enforce them consistently. SpaceX must establish safe avenues for reporting and uphold clear repercussions for all unacceptable behavior, whether from the CEO or an employee starting their first day.
We care deeply about SpaceX’s mission to make humanity multiplanetary. But more importantly, we care about each other. The collaboration we need to make life multiplanetary is incompatible with a culture that treats employees as consumable resources. Our unique position requires us to consider how our actions today will shape the experiences of individuals beyond our planet. Is the culture we are fostering now the one which we aim to bring to Mars and beyond?
We have made strides in that direction, but there is so much more to accomplish.

Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.
SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.

SpaceX has solved Starship’s biggest challenge, Elon Musk says
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.
Elon Musk sheds two new bits of detail on Starship after 13th test launch
Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
