SpaceX whistleblowers allege widespread sexual harassment
On the heels of a similar report on Blue Origin, five whistleblowers in two different exposes from Lioness and The Verge allege that SpaceX effectively fosters a work environment that is extremely hostile and unresponsive to women.
Above all else, all five former employees describe experiencing sexual harassment, inept responses from human resources (HR), and varying degrees of retaliation after attempting to pursue a fair corporate response. Ashley Kosack, a Rochester Institute of Technology Dean’s List graduate of mechanical engineering and a former SpaceX mission integration engineer and intern with almost four years of experience at the company between January 2017 and November 2021, is at the center of both reports.
First, it’s crucial to note that while several recent Blue Origin exposes alleged rampant sexual harassment and major internal issues that threatened the safety of its projects and of the space tourists that fly on its rockets, none of the whistleblowers attempting to hold SpaceX accountable for its poor treatment of women employees raised concerns about the company’s approach to safety. Nevertheless, Ashley Kosack, Julia CrowleyFarenga, and three other anonymous employees raise allegations that should still be taken seriously.
Above all else, the five describe an environment where women and nonbinary employees are regularly harassed by their male colleagues (ranging from fellow interns and entry-level engineers to managers and senior technicians), whose behavior is then effectively ignored or swept under the rug by SpaceX’s human resources department. In some cases, not only did HR fail to rectify the situation in any way, but they apparently made harassers aware of the allegation and the person alleging harassment. Some were then harassed more and retaliated against, often leading to severe stress and sometimes causing the harassed employees to quit outright.
In two particularly egregious examples, Kosack discovered that SpaceX – an almost two-decade-old company – apparently has no official HR system or mechanism in place to ensure that employees who harass other employees are not only punished accordingly, but at all. It’s difficult to assume anything good about the work culture of a company that explicitly refuses to ensure that sexual harassers face predictable repercussions for their actions. Later, when attempting to take advantage of SpaceX and COO Gwynne Shotwell’s often-advertised “Ethics and Compliance tip line,” Kosack discovered that the tip line wasn’t actually anonymous – making a farce of a tool theoretically meant to make internal whistleblowers feel comfortable enough to speak up.
One source that spoke to Teslarati revealed that that was also the case years ago and has even resulted in at least one employee being fired in retaliation for attempting to raise what they believed were real safety concerns. Shotwell, among others, reportedly receives all content submitted via the tip line. However, SpaceX has achieved an incredible record of success over the last five years, successfully completing more than 100 Falcon launches in a row. SpaceX, with NASA oversight, has also completed five crewed launches since May 2020, successfully launching 18 people in less than a year and half. If there are or were major safety concerns about how SpaceX was building, testing, or flying its Falcon rockets and Dragon spacecraft, that evidence suggests that the company is able to effectively deal with them.
All five whistleblowers still agreed that SpaceX is managing those feats despite consistently treating its workforce like an expendable resource – especially in the case of nonbinary and women employees. Even for men at SpaceX, it’s incredibly rare for employees to last more than five years – which, at least a few years ago, happens to be when accrued equity vests. As long as that remains the case and as long as employees feel like they’re hopeless in the face of egregious harassment, it’s hard to imagine that those retention issues will ever change or that SpaceX’s poor workforce diversity will ever significantly improve.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
