NASA human spaceflight chief resigns in surprise move before historic astronaut launch
SpaceX and NASA are eight days away from the first astronaut launch on U.S. soil in nearly a decade. There’s one big hurdle left to clear before the launch can get the go-ahead: it has to pass a flight readiness review. Typically that is led by the person in charge of NASA’s human exploration program.
However, that person — Doug Loverro — has resigned from NASA, effective May 18. According to an agency memo, Loverro resigned just six months after he took on the role. This marks the second time that such a big change in NASA leadership has occurred under the Trump administration. In July 2019, William Gerstenmaier was demoted from his position as NASA’s associate administrator from human exploration. Loverro took over his position several months later.
The space agency addressed the sudden departure of Loverro to its employees via a company-wide email. In the memo, it states, Loverro made significant progress in his time at NASA. “His leadership of [human exploration] has moved us closer to accomplishing our goal of landing the first woman and the next man on the Moon in 2024,” the memo reads. “Loverro has dedicated more than four decades of his life in service to our country, and we thank him for his service and contributions to the agency.”
Ken Bowersox, a five-time shuttle flier and former commander of the International Space Station, will take over for Loverro. Bowersox assumed the role after Gerstenmaier was demoted last year. He is the current deputy associate administrator for human exploration and is familiar with the commercial crew program and the upcoming SpaceX Crew Dragon flight.
The Loverro resignation is not related to Crew Dragon or any animosity between Doug and the NASA administrator. However the timing of this is devastating to the space agency.

That flight is scheduled for May 27 but first has to pass a series of readiness reviews. The first of which is scheduled for Thursday, May 21. Loverro was supposed to lead the flight readiness review, and with his departure, Steve Jurczyk, NASA’s associate administrator will lead the charge. If the Crew Dragon and its Falcon 9 launcher are cleared for flight, the launch will proceed as planned.
What effect will this change in leadership have on the upcoming launch? According to NASA, not much. “We have full confidence in the work [that commercial crew program manager] Kathy Lueders, and her entire Commercial Crew team have done to bring us here,” the memo states. “This test flight will be a historic and momentous occasion that will see the return of human spaceflight to our country, and the incredible dedication by the men and women of NASA is what has made this mission possible.”
In addition to the commercial crew program, Loverro was also head of the agency’s burgeoning Artemis program. NASA has plans to go back to the moon and do it sustainably, with the ultimate goal of sending the next man and the first woman to the moon by 2024. A lofty goal for sure.

In a memo to agency staff, Loverro explained that his departure had nothing to do with the work NASA was accomplishing. “I want to be clear that the fact that I am taking this step has nothing to do with your performance as an organization nor with the plans we have placed in motion to fulfill our mission,” Loverro wrote. “If anything, your performance and those plans make everything we have worked for over the past six months more attainable and more certain than ever before. My leaving is because of my personal actions, not anything we have accomplished together.”
He also explained that his abrupt departure had to do with a decision he made and a risk he took earlier in the year. “The risks we take, whether technical, political, or personal, all have potential consequences if we judge them incorrectly. I took such a risk earlier in the year because I judged it necessary to fulfill our mission,” he wrote. “Now, over the balance of time, it is clear that I made a mistake in that choice for which I alone must bear the consequences.”
Only time will tell how much this will or will not affect the upcoming crew launch, but as of now, it’s full-steam ahead.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.

The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.
As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality.
“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.
When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.
After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”
“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.
Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.
During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.
As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.
Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.
While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing.
“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.
“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said.
The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.
Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”
Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.
“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all.
“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.
