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.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
Recent sightings on public roads and growing fleet activity at Giga Texas signal Tesla’s accelerating push toward the Cybercab’s commercial launch.
Tesla Cybercab is being spotted with increasing frequency both on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production.
A total of 25 Cybercab units were recently observed across three separate locations at Giga Texas by drone observer Joe Tegtmeyer — with 14 metallic gold units parked in a tight formation outside the factory exit, nine more at the crash testing facility undergoing structural and safety validations, and two additional units at the west end-of-line area for final checks.
The activity on public roads is just as telling. The Cybercab was spotted testing on public roads for the first time last October, near Tesla’s Engineering Headquarters in Los Altos, California, marking a significant development in the vehicle’s progression toward commercial readiness. As expected at that early stage, a safety driver was present in the seat.
Since then, sightings have only become more frequent. Community observers on X have posted fresh footage of Cybercabs navigating public streets in Silicon Valley, with each new clip adding to a growing body of evidence that Tesla’s validation efforts are well underway. The production backdrop supports the momentum. Tesla’s production line at Giga Texas moved into a higher volume early in March, representing what observers are calling the largest single-day grouping of Cybercabs seen to date.

Tesla ramps Cybercab test manufacturing ahead of mass production
Musk has also stated that Tesla is aiming for at least 2 million Cybercab units per year across more than one factory, with a potential ceiling of 4 million annually.
With testing activity on public roads accelerating and factory output visibly increasing week over week, the coming months at Giga Texas are set to be pivotal in determining how quickly Tesla can bring the Cybercab from validation to volume.
