SpaceX attempts second Falcon fairing drop test with a helicopter and Mr. Steven
Following a few days of rest in port, SpaceX fairing recovery vessel Mr. Steven has continued a likely campaign of controlled drop tests with a second fairing recovery attempt, using a helicopter, spotter plane, and support vessel to pick up a Falcon fairing and drop it, theoretically allowing it to paraglide into Mr. Steven’s net.
While it’s nearly impossible to determine what happened without line-of-sight visual confirmation or an official announcement from SpaceX, it appears that Mr. Steven kicked off real catch attempts on October 11th, evidenced by his close interaction with a Blackhawk helicopter over the course of an hour or so. Another similar attempt occurred today, October 17th, and culminated with Mr. Steven returning once more to Port of San Pedro with the same test-focused fairing half on board, albeit not resting in his retracted net.

After October 11th’s testing was completed, Mr. Steven returned to Port of San Pedro. On October 13th, he was docked at SpaceX’s Berth 240 facilities with net lowered and the test fairing half wrapped up on the docks, preventing confirmation of whether he carried the fairing half back from the testing region. A mid-sized barge also recently appeared at Berth 240 with a distinct Falcon fairing cradle onboard, perhaps explaining the presence of a tugboat (named Sir Richard) a few miles away from where this test campaign has been stationed – a barge would offer a flat, safe surface for a helicopter to hover over and pick up an unwieldy object such as a payload fairing.
Nearly identical to the October 11th test, Mr. Steven, tug Sir Richard, a Cessna chase plane, and a Blackhawk helicopter all converged around 100 miles southwest of Port of Los Angeles around 2pm PDT on October 17th prior to beginning recovery test operations. Mr. Steven and the tug Sir Richard – likely towing a barge being temporarily used to move a fairing half – arrived several hours beforehand at the test’s planned location.

Eventually, a UH-60A Blackhawk helicopter – the same helicopter used on October 11 – lifted off from Catalina Island’s Avalon airport, taking about half an hour to reach Mr. Steven and Sir Richard. Once there, the helicopter very distinctly slowed down, eventually hovering just ~20 feet off the surface of the ocean, if not outright landing or perching on the aforementioned barge under the tug’s control. After several minutes in that state, the Blackhawk lifted off and immediately began climbing, reaching a peak of ~11,000 ft before (presumably) dropping its fairing payload and immediately diving down to follow its descent.
It’s undoubtedly an imperfect fit, but the helicopter appeared to follow Mr. Steven very closely over the course of the recovery attempt, sticking just a ~1500 ft or less above and a few hundred feet beside him as he raced to catch the falling fairing half. In fact, at least as a very rough approximation, the helicopter’s descent may be useful to judge the fairing’s behavior while gliding: taking ~14 minutes to travel descend 11,000ft and travel perhaps 2 miles (~10,500ft) horizontally, the fairing would dropped at a reasonable 13.1 feet per second (~4 m/s) once its parafoil opened and seemed to travel approximately one foot forward for every one foot down, also known as a 1:1 glide slope ratio.

Depending on wind conditions, parafoils can nominally be expected to achieve average glide slope ratios between 0 (high winds; falling like a literal rock) and 4 (no winds; almost as good as a bad airplane), meaning that Falcon fairings – judging from tangential data gathered from the helicopter following its descent – fly much like a parafoil, which is to say not great but better than a brick. The trick with parafoil control – which includes tweaking angles of attack and glide slope – lies more in the art of trading forward velocity for vertical velocity (or vice versa) at key moments. Assuming their control mechanisms have enough authority, paragliding fairings could ‘flare’ as they near Mr. Steven’s net, essentially angling upwards to briefly hover before dropping quickly, maybe giving the boat enough time to swoop in and place its net just beneath it.
In this way, a parafoil’s flexible, inflated wing (airfoil, to be precise) can allow it to maneuver quite a lot like a bird, at least more so than most other methods of flying humans have access to. Time will tell if SpaceX is having any luck perfecting the guidance and recovery of Falcon fairings, particularly with this campaign of under-the-radar drop tests. Even if Mr. Steven returns with a fairing half resting in his net, it will be more than a little ambiguous if it was placed there or he caught it, and any certainty will rely on official confirmation from SpaceX itself.

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.
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

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.
Tesla is rolling out a new version of its Full Self-Driving suite to some owners that comes with the massive addition of a safety feature.
Tesla is rolling out Automatic Collision Evasion with the 2026.27.6 Software Update, which started rolling out to some vehicles last night. We received the update, along with Full Self-Driving v14.3.9, as well as v14.2 Lite, which has identical release notes as the previous version and seems to have some refinements and improvements in behavior and performance.

However, most of the attention has fallen on the Automatic Collision Evasion feature, which we covered in an article last week.
The function will activate Full Self-Driving to “try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:
- Scenario 1: A frontal collision is imminent and braking alone may not avoid it.
- Scenario 2: Your vehicle detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.”
Essentially, FSD will take over when the vehicle determines you are not paying sufficient attention or are heading toward a potential collision. The addition of this feature is incredibly useful as distracted driving is a major issue in today’s world.
Along with the new safety feature is Tesla FSD v14.3.9, which has no additional release notes compared to the previous version, but in my first drives, my first impression is that operation is great, and parking is still sort of a pain point.
Just took a 15-mile round trip to the gym and back
Pretty on par with what FSD is nowadays – really good. Not enough time to see what’s good and what’s bad, but these first rides on any version feel shockingly good. They’re all pretty identical https://t.co/WN1qTg4bhE

Additionally, Tesla v14.2. Lite has arrived. A great review of that is available here:
— Zack (@BLKMDL3) September 9, 2026
The addition of an Automatic Collision Evasion feature is similar to that of other collision avoidance systems that are used by companies like Hyundai, Kia, and Genesis. These programs typically utilize radar and camera sensors to apply emergency brakes autonomously, though evasive steering in a manual driving mode is pioneered primarily by Tesla’s newest addition.
