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 owners surpass 8 billion miles driven on FSD Supervised
Tesla shared the milestone as adoption of the system accelerates across several markets.
Tesla owners have now driven more than 8 billion miles using Full Self-Driving Supervised, as per a new update from the electric vehicle maker’s official X account.
Tesla shared the milestone as adoption of the system accelerates across several markets.
“Tesla owners have now driven >8 billion miles on FSD Supervised,” the company wrote in its post on X. Tesla also included a graphic showing FSD Supervised’s miles driven before a collision, which far exceeds that of the United States average.
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.
Tesla also recently updated the safety data for FSD Supervised on its website, covering North America across all road types over the latest 12-month period.
As per Tesla’s figures, vehicles operating with FSD Supervised engaged recorded one major collision every 5,300,676 miles. In comparison, Teslas driven manually with Active Safety systems recorded one major collision every 2,175,763 miles, while Teslas driven manually without Active Safety recorded one major collision every 855,132 miles. The U.S. average during the same period was one major collision every 660,164 miles.
During the measured period, Tesla reported 830 total major collisions with FSD (Supervised) engaged, compared to 16,131 collisions for Teslas driven manually with Active Safety and 250 collisions for Teslas driven manually without Active Safety. Total miles logged exceeded 4.39 billion miles for FSD (Supervised) during the same timeframe.

The Boring Company’s Music City Loop gains unanimous approval
After eight months of negotiations, MNAA board members voted unanimously on Feb. 18 to move forward with the project.
The Metro Nashville Airport Authority (MNAA) has approved a 40-year agreement with Elon Musk’s The Boring Company to build the Music City Loop, a tunnel system linking Nashville International Airport to downtown.
After eight months of negotiations, MNAA board members voted unanimously on Feb. 18 to move forward with the project. Under the terms, The Boring Company will pay the airport authority an annual $300,000 licensing fee for the use of roughly 933,000 square feet of airport property, with a 3% annual increase.
Over 40 years, that totals to approximately $34 million, with two optional five-year extensions that could extend the term to 50 years, as per a report from The Tennesean.
The Boring Company celebrated the Music City Loop’s approval in a post on its official X account. “The Metropolitan Nashville Airport Authority has unanimously (7-0) approved a Music City Loop connection/station. Thanks so much to @Fly_Nashville for the great partnership,” the tunneling startup wrote in its post.
Once operational, the Music City Loop is expected to generate a $5 fee per airport pickup and drop-off, similar to rideshare charges. Airport officials estimate more than $300 million in operational revenue over the agreement’s duration, though this projection is deemed conservative.
“This is a significant benefit to the airport authority because we’re receiving a new way for our passengers to arrive downtown at zero capital investment from us. We don’t have to fund the operations and maintenance of that. TBC, The Boring Co., will do that for us,” MNAA President and CEO Doug Kreulen said.
The project has drawn both backing and criticism. Business leaders cited economic benefits and improved mobility between downtown and the airport. “Hospitality isn’t just an amenity. It’s an economic engine,” Strategic Hospitality’s Max Goldberg said.
Opponents, including state lawmakers, raised questions about environmental impacts, worker safety, and long-term risks. Sen. Heidi Campbell said, “Safety depends on rules applied evenly without exception… You’re not just evaluating a tunnel. You’re evaluating a risk, structural risk, legal risk, reputational risk and financial risk.”

Tesla announces crazy new Full Self-Driving milestone
The number of miles traveled has contextual significance for two reasons: one being the milestone itself, and another being Tesla’s continuing progress toward 10 billion miles of training data to achieve what CEO Elon Musk says will be the threshold needed to achieve unsupervised self-driving.
Tesla has announced a crazy new Full Self-Driving milestone, as it has officially confirmed drivers have surpassed over 8 billion miles traveled using the Full Self-Driving (Supervised) suite for semi-autonomous travel.
The FSD (Supervised) suite is one of the most robust on the market, and is among the safest from a data perspective available to the public.
On Wednesday, Tesla confirmed in a post on X that it has officially surpassed the 8 billion-mile mark, just a few months after reaching 7 billion cumulative miles, which was announced on December 27, 2025.

The number of miles traveled has contextual significance for two reasons: one being the milestone itself, and another being Tesla’s continuing progress toward 10 billion miles of training data to achieve what CEO Elon Musk says will be the threshold needed to achieve unsupervised self-driving.
The milestone itself is significant, especially considering Tesla has continued to gain valuable data from every mile traveled. However, the pace at which it is gathering these miles is getting faster.
Secondly, in January, Musk said the company would need “roughly 10 billion miles of training data” to achieve safe and unsupervised self-driving. “Reality has a super long tail of complexity,” Musk said.
Training data primarily means the fleet’s accumulated real-world miles that Tesla uses to train and improve its end-to-end AI models. This data captures the “long tail” — extremely rare, complex, or unpredictable situations that simulations alone cannot fully replicate at scale.
This is not the same as the total miles driven on Full Self-Driving, which is the 8 billion miles milestone that is being celebrated here.
The FSD-supervised miles contribute heavily to the training data, but the 10 billion figure is an estimate of the cumulative real-world exposure needed overall to push the system to human-level reliability.
