SpaceX’s Mr Steven gains upgraded arms to catch its first Falcon 9 fairings
SpaceX’s iconic Falcon 9 payload fairing recovery ship, known as Mr Steven, has been spotted in California’s Port of San Pedro having new arms installed with two cranes and a crew of SpaceX technicians. Aside from the sudden addition of dramatically different arm design, a large inflatable structure also took shape – seemingly overnight – right behind Mr Steven, the purpose of which is entirely unclear.
Incredibly, these massive new arms and their new equally large support struts and base plates have begun installation barely two weeks after Mr Steven took roost and had his old arms removed at SpaceX’s Berth 240 property. While the timeline of the arm and net upgrades – mentioned by CEO Elon Musk several weeks ago – was previously uncertain, the incredibly quick turnaround from old arm removal to new arm install suggests that SpaceX may, in fact, be aiming to have Mr Steven ready for recovery operations as early as Iridium-7, scheduled for launch on July 20th. In all likelihood, the fairing recovery vessel will be held up till the subsequent Vandenberg Air Force Base launch while a net with an area perhaps four times larger is custom-built for SpaceX.

Nevertheless, SpaceX’s speed rarely fails to surprise, and it’s entirely possible that a new, larger net was already ordered some time ago in preparation for the eventuality that Mr Steven’s first recovery mechanism was unsuccessful. Given the fact that at least two main arms and perhaps eight white, cylindrical struts have apparently been completed and are awaiting installation at Berth 240, it’s probable that the lead time on this new recovery mechanism stretches back at least several months, likely at least a month before Musk mentioned that Mr Steven would have its usable catching area grown “by a factor of [four]” in early June.
Yup, we are extending the net area by a factor of 4

Closing the fairing recovery gap
With four times the net available to catch wayward Falcon 9 payload fairings, SpaceX may be able to finally close the gap between Mr Steven and the successful and routine recovery and reuse of the second of three main Falcon 9 (and Heavy) components. At roughly 10% of the total cost (not price) of a single-booster Falcon 9, the considerable effort being put into the recovery of carbon-composite payload fairings is in a way motivated more by manufacturing bottlenecks than by the money it will save SpaceX (somewhat less than $3m per half).

SpaceX’s team of composite technicians and engineers will need to reliably fabricate as many as ~50 payload fairing halves in 2018, effectively one half each week
By recovering payload fairings before they touch the ocean surface, the company may – in one fell swoop – be able to dramatically reduce the operational expenditure required to sustain the annual production of dozens of Falcon fairings, each of which requires an inescapable and tediously slow stint in a massive autoclave, only a few of which can be squeeze into the company’s Hawthorne factory. As an example, SpaceX’s team of roughly 150 dedicated composite technicians and engineers will need to reliably fabricate as many as ~50 payload fairing halves – nearly a full half each week – to sustain SpaceX’s anticipated 2018 manifest of 24-28 launches, excluding three Cargo Dragon resupply missions that don’t need fairings.
While both Crew and Cargo Dragon spacecraft and trunks contain a large proportion of carbon fiber-composite structures, every composite Falcon 9 interstage that rolled off of the assembly line since February 2018 is part of a Block 5 booster and is thus expected to support a bare minimum of several missions on its own, functionally multiplying the useful output of any given production line even while the amount of work (and thus work-hours) is reduced. While Falcon 9 boosters – making up roughly 70% of the cost of the entire rocket – have been successfully upgraded to support several reuses each, SpaceX still has to produce a new payload fairing and upper stage for each launch. A spectacular Block 4 farewell earlier this month – complete with a recoverable booster expended to make way for Block 5 – simply served to emphasize the company’s desire to mitigate the expandability of both (currently) unreusable segments of Falcon 9.
- Meanwhile, the purpose of this massive inflatable ring is almost entirely unclear, as it would appear to be redundant with the initial installation of Mr Steven’s new recovery mechanism. (Pauline Acalin)
- Arm installation will presumably continue over the course of the week, hopefully reaching completion in time to recovery Iridium-7’s payload fairing. (Pauline Acalin)
If Mr Steven can recover even a small fraction – say 25% – of SpaceX payload fairings launched annually, the exact same level of effort (and thus capital) could support 25% more launches annually or reduce the work hours spent on fairing production by 25%. As it happens, SpaceX’s next-generation rocket (BFR) happens to be built (theoretically) almost entirely out of carbon-composites, from the propellant tanks to the spaceship’s delta wing.
Originally meant to focus on the wholly unexpected appearance of a giant inflatable structure at Berth 240, SpaceX’s breakneck pace of action abruptly recentered it on the equally unexpected installation of one the vessel’s first upgraded arms, meant to support a net that could be as much as four times larger than its predecessor. That symbolism on its own is a worthy representation of some of the best aspects of SpaceX’s world-class team of engineers and technicians, acting as a slightly more on-topic corollary to the equally rapid design, prototyping, fabrication, and testing of ad-hoc ‘submarines’ intended to help a number of Thai children currently trapped in a cave near the country’s border with Myanmar/Burma.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”

Tesla FSD (Supervised) blows away French journalist after test ride
Cadot described FSD as “mind-blowing,” both for the safety of the vehicle’s driving and the “humanity” of its driving behaviors.
Tesla’s Full Self-Driving (Supervised) seems to be making waves in Europe, with French tech journalist Julien Cadot recently sharing a positive first-hand experience from a supervised test drive in France.
Cadot, who tested the system for Numerama after eight years of anticipation since early Autopilot trials, described FSD as “mind-blowing,” both for the safety of the vehicle’s driving and the “humanity” of its driving behaviors.
Julien Cadot’s FSD test in France
Cadot announced his upcoming test on X, writing in French: “I’m going to test Tesla’s FSD for Numerama in France. 8 years I’ve been waiting to relive the sensations of our very first contact with the unbridled Autopilot of the 2016s.” He followed up shortly after with an initial reaction, writing: “I don’t want to spoil too much because as media we were allowed to film everything and I have a huge video coming… But: it’s mind-blowing! Both for safety and for the ‘humanity’ of the choices.”
His later posts detailed FSD’s specific maneuvers that he found particularly compelling. These include the vehicle safely overtaking a delivery truck by inches, something Cadot said he personally would avoid to protect his rims, but FSD handled flawlessly. He also praised FSD’s cyclist overtakes, as the system always maintained the required 1.5-meter distance by encroaching on the opposite lane when clear. Ultimately, Cadot noted FSD’s decision-making prioritized safety and advancement, which is pretty remarkable.
FSD’s ‘human’ edge over Autopilot
When asked if FSD felt light-years ahead of standard Autopilot, Cadot replied: “It’s incomparable, it’s not the same language.” He elaborated on scenarios like bypassing a parked delivery truck across a solid white line, where FSD assessed safety and proceeded just as a human driver might, rather than halting indefinitely. This “humanity” impressed Cadot the most, as it allowed FSD to fluidly navigate real-world chaos like urban Paris traffic.
Tesla is currently hard at work pushing for the rollout of FSD to several European countries. Recent reports have revealed that Tesla has received approval to operate 19 FSD test vehicles on Spain’s roads, though this number could increase as the program develops. As per the Dirección General de Tráfico (DGT), Tesla would be able to operate its FSD fleet on any national route across Spain. Recent job openings also hint at Tesla starting FSD tests in Austria. Apart from this, the company is also holding FSD demonstrations in Germany, France, and Italy.

Tesla Optimus shows off its newest capability as progress accelerates
Tesla Optimus showed off its newest capability as progress on the project continues to accelerate toward an ultimate goal of mass production in the coming years.
Tesla is still developing Optimus and preparing for the first stages of mass production, where units would be sold and shipped to customers. CEO Elon Musk has always marketed the humanoid robot as the biggest product in history, even outside of Tesla, but of all time.
He believes it will eliminate the need to manually perform monotonous tasks, like cleaning, mowing the lawn, and folding laundry.
However, lately, Musk has revealed even bigger plans for Optimus, including the ability to relieve humans of work entirely within the next 20 years.

Development at Tesla’s Artificial Intelligence and Robotics teams has progressed, and a new video was shown of the robot taking a light jog with what appeared to be some pretty natural form:

Optimus has also made several public appearances lately, including one at the Neural Information Processing Systems, or NeurIPS Conference. Some spectators shared videos of Optimus’s charging rig, as well as its movements and capabilities, most interestingly, the hand:

— Ric Burton · NeurIPS 2025 (@_ricburton) December 2, 2025
The hand, forearm, and fingers have been one of the most evident challenges for Tesla in recent times, especially as it continues to work on its 3rd Generation iteration of Optimus.
Musk said during the Q3 Earnings Call:
“I don’t want to downplay the difficulty, but it’s an incredibly difficult thing, especially to create a hand that is as dexterous and capable as the human hand, which is incredible. The human hand is an incredible thing. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason.”
The interesting part of the Optimus program so far is the fact that Tesla has made a lot of progress with other portions of the project, like movement, for example, which appears to have come a long way.
However, without a functional hand and fingers, Optimus could be rendered relatively useless, so it is evident that it has to figure this crucial part out first.
