With less than a month to go before NASA’s first crewed launch in nearly a decade, the space agency is still mulling over the details. On May 27, Bob Behnken and Doug Hurley will strap into their Crew Dragon spacecraft and blast off towards the International Space Station. During their stay, the duo will assist fellow NASA astronaut, Chris Cassidy, in maintaining the station as well as conducting several research experiments.

But how long the duo will remain on the station is still up in the air. NASA held a series of briefings on Friday, May 1, detailing the historic mission and how it would work. Hurley and Behnken will launch from Pad 39A at Kennedy Space Center at 4:32 p.m. EDT (20:32 UTC), and dock with the space station 24 hours later.

The exact length of that mission will be determined during their time in space. “It is a trade-off,” Kirk Shireman, NASA ISS program manager said during the news briefing, “between getting the spacecraft back quickly to complete its certification and providing additional crew time on the station for maintenance and research.”

The Demo-2 mission is a test flight. NASA and SpaceX will be using the mission to certify the Crew Dragon spacecraft for regular use to and from the station. So during this flight, the crew will try their hands at manual control and will test and monitor on boars systems during the significant phases of flight: launch, on orbit, and during re-entry.

Once the vehicle has completed its objectives successfully, it will be certified for a crewed flight. Currently, SpaceX is nearing completion on the next Dragon spacecraft, which will ferry four astronauts to the station for a long-duration mission. During the news briefings, SpaceX COO Gwynne Shotwell announced that the spacecraft for that mission is nearing completion and should arrive in Florida in the next couple of months.

Shireman said that the length of the Demo-2 mission was directly tied to that vehicle’s progress. “What we would like to do, from a station perspective, is to keep them on orbit as long as we can until that Crew-1 vehicle is just about ready to go, bring Demo-2 home, allow that certification work to be completed and launch Crew-1,” he said.

Steve Stich, NASA’s deputy manager of the commercial crew program, said that at minimum, the DM-2 crew would stay on orbit about a month. Their maximum stay would be no more than 119 days, due to the potential degradation of the Dragon spacecraft’s solar panels.

Solar panels are how spacecraft get their power while on orbit, and the sensitive components within the hardware degrade over time thanks to the harshness of the space environment. While it’s on orbit, ground control teams will “wake up” the spacecraft once a week to perform health checks and test the solar array’s performance.

“We would like to fly a mission that is as long as we need to for a test flight, but also support some of the space station program needs,” Stitch said.

Originally, Behnken and Hurley were expected to have a much shorter time on orbit. However, NASA officials said they started to explore the possibility of extending their mission six months ago to ensure there were enough astronauts onboard the space station to keep the orbital outpost in top shape. This year the agency is celebrating 20 years of continuous human presence on the space station, and NASA would like to ensure its continuation into the future.

To that end, Behnken and Hurley have spent significant time training to refresh themselves on station systems as well as prepare the potential spacewalks. A new shipment of batteries is scheduled to arrive on station a few days before Behnken and Hurley, and it’s possible that Behnken could be asked to conduct a spacewalk, along with Chris Cassidy.

The top priority for Behnken and Hurley will be to thoroughly check out the Crew Dragon’s systems, followed closely by relieving Chris Cassidy. “There’s a lot of work and activity that can be done in the U.S. segment; certainly more than one person can accomplish on their own,” Behnken explained during a later briefing.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles

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 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

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.
