Mars has competition from Venus after new study shows signs of life
NASA and SpaceX are simultaneously planning their trips to Mars and the Moon, but a recent study published in Nature Astronomy has brought a different planet into the running for a new near-term exploration mission: Venus.
A team of scientists led by Dr. Jane Graeves of Cardiff University in the UK just announced the discovery of phosphine in the clouds of Venus. This rare molecule is made either industrially or as a byproduct of microbes that live in oxygen-free environments, meaning there’s serious evidence that life may exist on our sister planet.
“This was an experiment made out of pure curiosity, really,” Dr. Graeves detailed to the Royal Astronomical Society. “I thought we’d just be able to rule out extreme scenarios, like the clouds being stuffed full of organisms. When we got the first hints of phosphine in Venus’ spectrum, it was a shock!”
With NASA’s 2020 Mars Rover Perseverance on its way to do some astrobiological science on our red neighbor, this new finding on Venus looks to now have some high-level advocates for prioritized exploration.
“Life on Venus? The discovery of phosphine, a byproduct of anaerobic biology, is the most significant development yet in building the case for life off Earth,” NASA Administrator Jim Bridenstine tweeted about the news shortly after its publication. “About 10 years ago NASA discovered microbial life at 120,000ft in Earth’s upper atmosphere. It’s time to prioritize Venus.”

Planetary scientist Paul Byrne of North Carolina State University echoed this same sentiment in a quote published by The New York Times. “If this planet is active and is producing phosphine, and there is something that’s making it in the Venus atmosphere, then by God almighty, forget this Mars nonsense,” Byrne opined. “We need a lander, an orbiter, we need a program.”
Similar to thinking about Mars’ ancient past being filled with more Earth-like components such as water bodies (or perhaps not), Venus is thought to have been the home to lakes, rivers, and oceans before a runaway greenhouse effect made it into the hellish landscape it is today. This thinking has partly lead to speculation about the possibility of microbes migrating or developing in the clouds of the planet as ‘aerial’ life where temperatures are much more Earth-like, albeit very acidic. “Finding phosphine on Venus was an unexpected bonus! The discovery raises many questions, such as how any organisms could survive. On Earth, some microbes can cope with up to about 5% of acid in their environment – but the clouds of Venus are almost entirely made of acid,” commented team member Dr. Clara Sousa Silva of MIT.
For planetary science enthusiasts, of course, the idea of looking for life or even a new home for humans in the clouds of Venus isn’t new. Astrobiologist David Grinspoon, for one, has been advocating for the planet’s cause for quite some time. “Venus, this planet where I’ve been proposing for decades that there could be a biosphere in the clouds,” he exclaimed in a recent video chat about the discovery. “I mean, Venus is a place we do not associate with extraterrestrial life… It’s so hot, and so dry, the pressure’s so huge…we think life is gonna be anywhere but Venus. But interestingly if you go 30 miles up into the clouds, it’s rather comfortable in the sense that it’s sort of like room temperature [and pressure] in the room you’re in right now.”
The discovery of phosphine on Venus is also exciting for exoplanet hunting endeavors, i.e., looking for signs of life on planets outside our solar system. “It’s very exciting because phosphine is a gas that should not exist in an atmosphere like Venus’,” Grinspoon explained. “It stands out as an anomaly… Not only that, phosphine has been previously suggested as a very good biosignature that we might find on an exoplanet – a gas that’s made by life. It’s not easy to make in non-biological ways.”
A renewed call for Venusian exploration is already ready to be answered by a few scientists and groups, one notable example being startup launch provider Rocket Lab. As a rocket company focused on dedicated missions for small payloads, Rocket Lab stands as a ready and willing partner for any organization looking to gather more data from Venus directly. In fact, CEO Peter Beck already has plans in the works for the planet most symbolically synonymous with romance.
“I’m madly in love with Venus,” Beck said on August 5th this year during a live streamed company update. “I’m working very hard to put together a private mission to go to Venus in 2023… At the very least, I think it’s a needle-mover even for just a private mission to try and go do something interplanetary. That sends a message to the rest of the world that, ‘Hey, look — we can do these things privately.’”
Another notable mission that’s relevant to Beck and Rocket Lab’s goals for small payload missions to interplanetary destinations was the Mars Cube One companions of NASA’s InSight lander launched in 2018. After traveling the the red planet with the lander, the twin cube satellites were able to send back data and a photo of Mars to Earth. This proved that tiny affordable spacecraft could be used for some serious deep-space science. Perhaps one of the biggest discoveries in our solar system of late could be followed up by an itty bitty mission (respectively)?

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.
