SpaceX-launched Uranus mission a top priority of new decadal survey
The National Academies of Sciences, Engineering, and Medicine have published their latest decadal survey of planetary science and astrobiology, revealing a recommendation that NASA prioritize the development of a flagship mission to Uranus baselined to launch on SpaceX’s Falcon Heavy rocket.
Known as the Uranus Orbiter and Probe or UOP, the mission proposal has been under development by a team of NASA, University of California, and Johns Hopkins University scientists and engineers for several years. In fact, a very similar concept ranked third in the Academies’ 2013-2022 decadal survey flagship recommendations, reiterating its central importance and potential value in the eyes of the survey’s dozens of contributors. According to its creators, in its latest iteration, the Uranus Orbiter and Probe have the potential to fully or partially answer 11 of the 12 primary questions the latest Decadal Survey structured itself around.
Additionally, the survey indirectly states that if it weren’t for the existence of one specific technology, it would have been a wash between a mission to Uranus or Neptune. That keystone: SpaceX’s Falcon Heavy rocket.
While the survey’s authors don’t explicitly point to SpaceX in the context of UOP, they do state that “a Uranus mission is favored because an end-to-end mission concept exists that can be implemented in the 2023-2032 decade on currently available launch vehicles.” In reality, there only appears to be one launch vehicle: Falcon Heavy. Three other alternatives do technically exist: United Launch Alliance’s (ULA) Vulcan Centaur, Blue Origin’s New Glenn, and NASA’s own Space Launch System (SLS).
NASA’s Europa Clipper orbiter – originally manifested on SLS but later moved to SpaceX’s Falcon Heavy to avoid major launch delays – has helped demonstrate that SLS isn’t viable for non-Artemis Program missions without massive production improvements and significant workarounds or design changes. While capable in many regards, Blue Origin’s reusable New Glenn rocket appears to have extremely poor performance beyond Earth orbit – well below what UOP requires – and is unlikely to launch before 2024 or 2025. It’s possible that an expendable New Glenn could suffice but Blue Origin has never mentioned the option and, even then, the rocket’s expendable performance could still fall short.
Finally, ULA’s expendable Vulcan Centaur rocket has yet to launch and its debut could easily slip into 2023. More importantly, according to official information provided by the company to a NASA-run performance calculator, even Vulcan’s most capable variant (VC6) with six solid rocket boosters (SRBs) simply doesn’t have the performance required to launch the Uranus Orbiter and Probe (7235 kg / 15,950 lb) on seven of the mission’s preferred trajectories. For three other secondary windows, Vulcan could potentially launch UOP but only with the inclusion of a Venus gravity assist that would require significant design changes to protect the spacecraft while traveling much closer to the sun.
According to NASA’s calculator, a fully-expendable Falcon Heavy rocket with a standard payload fairing could launch around 8.5-10 tons (18,700-22,000 lb) to UOP’s preferred trajectories, leaving a very healthy margin for spacecraft weight gain or launch underperformance and likely enabling a longer launch window for each opportunity.
If NASA agrees with the survey’s conclusions, decides to develop the Uranus Orbiter and Probe, and also plans on the Academies’ optimistic assumption of an ~18% budget increase on average from 2023 to 2032, work towards a preferred 2031 launch window could begin in earnest as early as 2024. Comprised of a namesake Orbiter and Probe, UOP would arrive in orbit around Uranus in late 2044 or early 2045 weighing around five metric tons (~11,000 lb). The primary science mission would begin by deploying a small atmospheric probe to directly analyze the composition and behavior of the planet’s exotic atmosphere, which is believed to be volatile, prone to vast and violent storms, and host to some of the most extreme winds in the solar system. The probe would weigh ~270 kilograms (~600 lb) and is only expected to survive for a few hours at most.
The orbiter, however, would continue on to tour the Uranian system for at least four years, observing and studying the ice giant and its rings, magnetosphere, and 27+ moons. Uranus itself resides in what may be the most common class of exoplanets in the universe, making a close study of it invaluable for exoplanet science as a whole. It’s also possible that – like several moons around Saturn and Jupiter – one or more Uranian moons have liquid water oceans created by tidal heating, adding to the list of extraterrestrial bodies that might feature habitable environments or alien life.

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.
