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

Elon Musk rips ABC News over fatal NYC Tesla crash report
Musk pushed back on NYC Tesla crash coverage, pointing to a pattern of premature blame.
Elon Musk pushed back overnight against media framing of a fatal Tesla crash in Midtown Manhattan, telling a user on X that “it wasn’t the car” and that the vehicle’s Autopilot system had nothing to do with the wreck.
The crash happened just before 3 a.m. Wednesday, when a 2024 Tesla Model Y struck a sidewalk shed outside 315 Madison Ave., a bus stop pole and a mailbox on East 42nd Street, according to the NYPD. The car kept moving several more blocks before stopping near Second Avenue. Both women inside, each 27, were taken to Bellevue Hospital, where the passenger was pronounced dead. The driver was charged with vehicular manslaughter, driving while ability impaired and leaving the scene of an accident.
Police have not attributed the crash to Autopilot or Full Self-Driving in any public statement. The charges point to impairment, not software. Musk’s response followed a since-deleted ABC News post that he said mischaracterized the incident. Replying to a user on X, Musk wrote that if Autopilot had been engaged, “they would not have crashed,” and added that “the legacy media will never forgive Tesla for failing to advertise with them,”

It’s a familiar cycle for Tesla. In June, headlines from several national outlets described a fatal crash in Katy, Texas, as happening while the car was “on autopilot,” based on the driver’s own account to police after his Model 3 struck a home and killed a 76-year-old woman. Tesla’s data told a different story when Ashok Elluswamy, Tesla’s head of AI, said the driver had pressed the accelerator to 100% and reached 73 mph in a residential zone. Harris County prosecutors later confirmed the human override and the driver was charged with manslaughter.
Florida Gov. Ron DeSantis pointed to that same Katy crash last month to argue that outlets routinely name Tesla in crash headlines while leaving other automakers unnamed, even after a driver’s own actions are shown to be the cause. A similar pattern played out in 2024, when Musk had to clarify that FSD was never even downloaded onto the Model 3 involved in a fatal Colorado DUI crash, despite a passenger’s claim that an “auto drive feature” was in use.
Tesla has not issued a separate statement on the Manhattan crash beyond Musk’s posts on X. The NYPD’s investigation is ongoing, and no cause for the driver losing control has been released.

Tesla’s two defunct flagship models are getting a big upgrade
Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.
Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:
For my @Tesla friends – and specifically Model S & X owners with HW3 who are waiting on FSD v14 Lite – I spoke to @aelluswamy at the Cybercab launch, & when I asked for an ETA on v14 Lite for S/X owners, he said, “Oh, I thought it was supposed to go out last week.”
So: soon! 🙌

Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.
Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.
v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.
Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.
The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.
Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.
A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.
Elluswamy called that version the one “likely going to wide release.”
That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.
There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.
Cybertruck
This tiny Tesla Cybertruck adjustment has big advantages
Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.
Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup
One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.
Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.
Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.
The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.
The side repeater camera was updated – the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement. pic.twitter.com/wAbXtcL1Jf
— Wes (@wmorrill3) September 8, 2026
The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.
In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.
Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.
The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.
The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.
New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.
A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.
This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.
