NASA and SpaceX probably can’t terraform Mars but that doesn’t matter

Published

In recent weeks, a great deal of exaggerative noise has been spread wide about the supposed impossibility of making the planet Mars more Earth-like and hospitable, a concept known as terraforming. The reality is quite a bit different, especially within the context of any SpaceX or NASA-driven human outposts or colonization attempts.

Triggered by comparatively reasonable research just published by two experienced planetary scientists, much of the hyperbolic media coverage that followed failed to properly frame the true challenges of terraforming the Red Planet.

The entire limb of Mars captured by ESA’s Mars Express orbiter, June 2017.

Keeping the cart behind the horse

Before anything else, it’s critical to take a step back from the idea of terraforming and consider the simpler facts of any human presence on Mars. First, the rationale for a permanent human presence on Mars is largely independent of the environmental conditions on the planet – it’s a huge help to have basic resources available in situ (on site), but the difficulty of surviving in a given non-Earth environment is immaterial to the human desire to both explore and survive.

Assuming we humans really do want to ensure that a subset of ourselves can independently survive any truly global catastrophe on Earth, be it natural or artificial, we will find a way to do so in even the harshest of environments. Living on Mars would be downright luxurious compared to life aboard the International Space Station, thanks largely to ~1/3rd Earth gravity, accessible natural resources to replenish consumables, an Earthlike day and night cycle, considerably more forgiving temperature extremes, and much more.

Despite the inhospitable conditions, human presence aboard the ISS has been uninterrupted for nearly 20 years, even though the average stay per crewmember sits around six months. The ISS also has the luxury of a 90 minute day/night cycle, 100% unfiltered sunlight for peak solar panel efficiency, regular resupply missions from Earth, and an escape route in the event of a catastrophic failure. That escape method (Soyuz capsules docked to the station) has not once been used, aside from a handful of instances where crew boarded their escape vehicles as a cautionary measure during unusually risky space debris events, an absolute non-issue on Mars’ surface.

Put simply: if humans can live in orbit for long periods, they can also survive on Mars with at least the same level of difficulty.

Getting there is the hardest part

By taking natural resources available on Mars (namely water and carbon dioxide) and using them to repopulate the planet’s withered atmosphere, it has long been hoped that the Martian surface might be brought much closer to that of Earth, with a thicker atmosphere translating into familiar air pressure and a far warmer climate. In its current state, humans would always need to wear pressure suits and carry oxygen when traveling beyond their Martian habitats, as Mars’ 0.06 bar atmosphere would be approximately as forgiving as the naked vacuum of space and only moderately warmer.

Terraforming could potentially alleviate those significant points against the Red Planet, although updated research published this year (2018) appears to indicate otherwise. In reality, Jakosky and Edwards’ study simply emphasizes and adds on to what should already have been wildly apparent – making desolate planets Earthlike is almost invariably going to be an unfathomably difficult (but by no means impossible) challenge, and is most likely beyond the reach of present-day humanity.

 

It also happens to be the case that terraforming as a concept is utterly irrelevant without the means to get to and – more importantly – transport respectable amounts of cargo to the bodies one hopes to one day transform. SpaceX’s BFR transportation system is one such acknowledgment of that problem – the issue with Mars colonization or really any basic human presence at all is not surviving after arrival, but instead actually getting there in the first place and doing so without taking decades or bankrupting entire nations.

Extremely affordable transport to, from, and between orbits happen to be the most unequivocal requirement for both a permanent human presence on other planets and have any hope at all of terraforming them, but it just so happens that the latter is 100% irrelevant and impossible without the former. Let’s seriously worry and argue about terraforming Mars once we can do so from the surface of the Red Planet and focus first on getting there.

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

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.
