SpaceX eyes major drone ship fleet upgrades and a new rocket recovery robot

SpaceX has kicked off a series of major upgrades planned for its East Coast fleet of drone ships, centered around Just Read The Instructions (JRTI) and most recently culminating in the apparent fabrication of a second tank-like rocket recovery robot.

Back in Q4 2019, West Coast drone ship JRTI officially departed the Port of Los Angeles berth it operated out of for 3+ years — traversing the Panama Canal, making a weeks-long pit-stop in a Louisiana port, and ultimately arriving at Port Canaveral on December 11th. The modified barge spent more than a month relatively untouched – as was the somewhat mysterious cargo it had brought with it from the Gulf Coast – before SpaceX began JRTI’s long-awaited upgrades around a month ago.

For almost half a year, it’s looked like that SpaceX would move its West Coast drone ship to Florida after the company’s Vandenberg Air Force Base (VAFB) pad entered a major lull in launch activities in early 2019. Aside from one launch in June 2019, SpaceX’s West Coast pad has remained unused and that isn’t expected to change anytime soon. With Cape Canaveral potential reopening its dormant polar launch corridor just weeks from now, it’s entirely possible that SpaceX will be able to perform all of its planned launches from Florida alone for at least the next 6-12 months. Targeting more than 30 East Coast launches in 2020 alone, SpaceX could also benefit from at least one additional drone ship to continue high-volume Falcon booster recoveries without ship availability becoming a major launch constraint. Thankfully, JRTI may be the perfect solution.

Informally known as ‘Octagrabber’, a reference to the robot’s primary function, SpaceX has been using the only operational instance of the vehicle on drone ship Of Course I Still Love You (OCISLY) for more than two years, beginning in 2017. While far from autonomous, Octagrabber helps SpaceX’s maritime rocket recovery team minimize the risks workers are subjected to and gives the company a bit more flexibility to attempt Falcon booster landings in less-than-pristine ocean weather.

While Falcon boosters are relatively stable once landed, thanks to the vast majority of their empty mass being concentrated around their nine Merlin 1D engines, even moderate waves can cause them to slip and slide around the drone ship deck.

In fact, the best operational demonstration of the value of Octagrabber-style recovery robots came after SpaceX’s historic Falcon Heavy triple-booster recovery in April 2019 – the first time all three of the rocket’s first stage boosters successfully landed after liftoff. As it turns out, thanks to moderate hardware differences between Falcon Heavy center core boosters and normal Falcon 9 boosters, OCISLY’s Octagrabber robot did not have the attachment mechanisms needed to ‘grab’ the center core (B1055, in this case). In theory, this could be a non-issue but the drone ship unfortunately ran into high seas, making its deck to pitch and tilt and ultimately causing to B1055 to tip over, breaking in half and effectively destroyed the booster.

With Octagrabber robots, drone ships should almost never lose recovered boosters because of high seas (within reason). As such, it should come as no surprise at all that SpaceX is building a new recovery robot for drone ship JRTI – the newest addition to its Florida fleet.

Aside from the discovery of a second Octagrabber being built at SpaceX’s former East Coast Starship factory, the nature of other upgrades planned for drone ship JRTI are more mysterious. For several months, the rocket landing platform has had almost a dozen massive generators and new thruster pods stored on its deck, seemingly waiting on an unknown impetus for their installation. In recent weeks, visible work to prepare the new hardware for installation has begun.

Notably, the thrusters and power supplies that seem destined for installation on JRTI would make for a dramatic upgrade, potentially giving the drone ship more power than the tug boats that must currently tender and tow them to landing zones. In other words, that’s a complicated way of saying that SpaceX may be trying to make drone ship JRTI almost entirely independent of contracted tugboats, potentially simplifying and lowering the cost of booster recoveries.

One day soon, SpaceX’s upgraded drone ships may be able to recover boosters and return them to shore without any human technicians. (Richard Angle)

While less likely, it’s also possible that SpaceX is finally in a position to fully realize the “autonomous” namesake of its autonomous spaceport drone ships (ASDS), with high-powered thrusters potentially giving JRTI the ability to leave port, cruise to Atlantic Ocean landing zones, deploy an Octagrabber, and return to port with a booster – all without humans in the loop. That capability is likely still on the horizon but powerful thrusters and generators would bring port-to-port drone ship autonomy within SpaceX’s grasp in the near future.

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.
