LIVESTREAM: SpaceX, NASA set for a second shot at historic astronaut launch
SpaceX and NASA are on track for the private launch company’s second shot at their astronaut launch debut, set to be broadcast live from start to finish.
Even more so than SpaceX’s first May 27th attempt, weather continues to be the biggest challenge threatening delays to the historic mission, itself an impressive achievement for a vehicle, rocket, and system as complex as the Crew Dragon spacecraft, Falcon 9 rocket, Pad 39A facilities, and NASA astronauts Bob Behnken and Doug Hurley. With weather predicted to be ~50% favorable come liftoff, SpaceX and NASA are still proceeding to the countdown and remain scheduled to launch at 3:22 pm EDT (19:22 UTC).
As previously discussed on Teslarati, Crew Dragon astronaut launches are going to be uniquely sensitive to weather conditions.
“For two interconnected reasons, SpaceX’s Crew Dragon astronaut missions are going to be extraordinarily sensitive to weather restrictions come launch day, a fact that has come to partially dominate the tone of Demo-2 preparations over the last few days. First and foremost, NASA’s single highest priority for crewed Commercial Crew Program (CCP) launches is and will continue to be astronaut safety.
As a direct result of SpaceX’s significant safety improvements, it and NASA are ironically going to have a more challenging time launching Crew Dragon as dozens of possible abort splashdown locations stretching across the Atlantic Ocean will have to be constantly monitored for weather violations. SpaceX Vice President of Build and Reliability Hans Koenigsmann described the method of weighing those dozens of sites as an extremely complex algorithm, suggesting that unacceptable weather in certain spots might not fully delay a launch opportunity.”

The challenges, however, are undoubtedly worth it. SpaceX’s inaugural astronaut launch will arguably be the single most important launch in the company’s 18-year history.
“The stakes have never been higher for the 18-year-old Elon Musk venture. If successful, Demo-2 will catapult the company into an unprecedented era, proving countless traditional aerospace naysayers wrong and beating the likes of Boeing to the punch — all with a self-built reusable rocket and spacecraft that are dramatically cheaper than their closest competitors. It will be the single most encouraging step SpaceX has taken towards the permanent settlement of the solar system. On the other side of the double-edged sword, if things go south, it’s hard to exaggerate the scale of the setback and road to retribution that would face the pioneering spaceflight company.”

As of now, NASA astronauts Bob Behnken and Doug Hurley have boarded the orbit-bound Crew Dragon capsule installed atop a Falcon 9 rocket at Pad 39A and could be just a few hours away from liftoff – weather permitting. Stay tuned for updates as we close in on a second attempt at the historic event and watch live as SpaceX and NASA complete the last steps before launch.

SpaceX pursues 5G-level connectivity with Starlink Mobile V2 expansion
SpaceX noted that the upcoming Starlink V2 satellites will deliver up to 100 times the data density of the current first-generation system.
SpaceX has previewed a major upgrade to Starlink Mobile, outlining next-generation satellites that aim to deliver significantly higher capacity and full 5G-level connectivity directly to mobile phones.
The update comes as Starlink rebrands its Direct-to-Cell service to Starlink Mobile, positioning the platform as a scalable satellite-to-mobile solution that’s integrated with global telecom partners.
SpaceX noted that the upcoming Starlink V2 satellites will deliver up to 100 times the data density of the current first-generation system. The company also noted that the new V2 satellites are designed to provide significantly higher throughput capability compared to its current iteration.
“The next generation of Starlink Mobile satellites – V2 – will deliver full cellular coverage to places never thought possible via the highest performing satellite-to-mobile network ever built.
“Driven by custom SpaceX-designed silicon and phased array antennas, the satellites will support thousands of spatial beams and higher bandwidth capability, enabling around 20x the throughput capability as compared to a first-generation satellite,” SpaceX wrote in its official Starlink Mobile page.
Thanks to the higher bandwidth of Starlink Mobile, users should be able to stream, browse the internet, use high-speed apps, and enjoy voice services comparable to terrestrial cellular networks.
In most environments, Starlink says the upgraded system will enable full 5G cellular connectivity with a user experience similar to existing ground-based networks.
The satellites function as “cell towers in space,” using advanced phased-array antennas and laser interlinks to integrate with terrestrial infrastructure in a roaming-like architecture.
“Starlink Mobile works with existing LTE phones wherever you can see the sky. The satellites have an antenna that acts like a cellphone tower in space, the most advanced phased array antennas in the world that connect seamlessly over lasers to any point in the globe, allowing network integration similar to a standard roaming partner,” SpaceX wrote.
Starlink Mobile currently operates with approximately 650 satellites in low-Earth orbit and is active across more than 32 countries, representing over 1.7 billion people through partnerships with mobile network operators. Starlink Mobile’s current partnerships span North America, Europe, Asia, Africa, and Oceania, allowing reciprocal access across participating nations.

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.
