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 Semi gets strange-but-understandable comparison from Jay Leno

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.
In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:
“It’s like driving an office building.”
The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.
Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.
“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.
Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.
Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.
Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.
Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.
Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.
Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.
Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold
Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.
Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.
The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla expands its mass-market color palette in the U.S.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads.
Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.
Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.
Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.
The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.
Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.
Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

Tesla Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
