SpaceX Falcon fairing recovery vessel Mr. Steven tests out new limbs at sea
After a week or so spent installing a new and moderately ambiguous arm on the nose of Falcon fairing recovery vessel Mr. Steven, SpaceX’s recovery crew performed a number of high-speed sea trials a few miles off the shore of Port of Los Angeles, testing out something.
Just a few days later, Mr. Steven returned to the general region surrounding Catalina Island, where – by all appearances – SpaceX technicians performed the most recent Falcon fairing drop/catch test. Using a helicopter to pick up the test-dedicated fairing half from a barge, eventually dropping it from around 10,000 feet, this offers Mr. Steven a much higher volume of controlled attempts at both catching a parasailing fairing and optimizing the technology and recovery methods involved.

Over the last few weeks, Teslarati photographer Pauline Acalin has reliably kept up with Mr. Steven, documenting a variety of recent physical changes to the vessel. Most notably, these changes include the installation of a visible and quite curious stanchion (or arm) at the ship’s aft tip (nose). Simply due to a lack of any real information about the experiences of operating Mr. Steven and attempting to catch Falcon fairings, it’s all but impossible to know for sure what this new limb accomplishes or why it was needed in the first place.
Armed to the teeth
More clear are general visual observations and the reasonable extrapolations that can be derived from them. At the simplest level, this new limb is clearly well-reinforced, at least no less so than any of Mr. Steven’s other arms and attachment points. Aside from a basic off-the-shelf ladder for crew and technician access, the stanchion plays host to four basic swinging arms with what looks like one or maybe one and a half degrees of freedom, allowing them to pivot roughly 180 degrees along the plane of the angle they were installed at.

Secured to the ends of those four simple arms are four heavy-duty coiled metal cables, themselves attached to the center of Mr. Steven’s two foremost arms (two cables per arm). Curiously, the ship’s Nov. 12 sea trials were conducted with just the bottom two cables attached to each respective arm, visible in photos of the outing. Upon returning from a Nov. 14 fairing drop-and-catch test, both upper and lower cable sets were seen attached to his aft arms. During the nearby sea trials, no clearly abnormal behavior – compared against previous trials at similar speeds and the same location – was observed, although the new metal cables were visibly taut or nearly so.
Given just how seemingly nuanced the utility of this new arm and cable combo seems to be, a few obvious conclusions and possible explanations can be drawn. Perhaps Mr. Steven experiences inconvenient arm bouncing while sailing at high speeds, particularly in high speeds, and holding his arms down serves to grease the metaphorical gears of fairing recovery. Maybe the recovery net – stretched between four large arms – is tensioned more than SpaceX fairing recovery engineers and technicians would like, partially shrinking the usable catching area by pulling each arm towards the center. Even more nuanced still, it may be the case that these new tensioning steel cables and stanchion make it easier for fairing halves to be processed after landing in Mr. Steven’s net, allowing the crew to accurately and rapidly move the fairing to an optimal section of the net.

More questions than answers
Regardless, none of these best-case, simple explanations for the new hardware satisfactorily mesh with the known facts surrounding Mr. Steven and Falcon fairing recovery in general. For any of the above scenarios to be true, one must essentially assume that SpaceX has already nailed down fairing recovery and catches or believes that the path to solving those problems is almost totally clear of obstacles. If not, it would feel more than a little like putting the cart before the horse (or the fairing before the net) to be optimizing Mr. Steven for operations that are – as of yet – out of reach.
If SpaceX were so close to closing the fairing recovery gap, one would generally expect Mr. Steven to attempt fairing recoveries after all true Falcon 9 launches while also performing controlled drop test catch attempts. However, no such attempt was made after the October 7 launch of SAOCOM-1A and – according to CEO Elon Musk – Mr. Steven will not be attempting to catch Falcon 9’s fairing(s) after the imminent launch of SSO-A, expected to occur sometime after Thanksgiving (later this week).
Will try again next month

Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:
Robotaxi rides without any safety monitors are now publicly available in Austin.
Starting with a few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors, and the ratio will increase over time. https://t.co/ShMpZjefwB

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
