SpaceX’s Mr. Steven returns with Falcon fairing half in net after drop test practice
Captured in a series of photos taken by Teslarati photographers Pauline Acalin and Tom Cross over several days, SpaceX Falcon fairing recovery vessel Mr. Steven and recovery technicians and engineers have been preparing and practicing for a campaign of controlled fairing drop tests.
By using a helicopter to lift and drop a fairing into Mr. Steven’s net, SpaceX will be able to gather an unprecedented amount of data and control far more variables that might impact the success of recoveries. If the fairing is not destroyed in the process, this test series could be as long-lived as SpaceX’s Grasshopper program, used to work the largest up-front kinks out of Falcon 9 booster recovery.
Mr Steven looks ready. Should be leaving port at some point today ahead of SAOCOM-1A launch scheduled for Sunday, Oct 7, 7:21pm PT #mrsteven #SpaceX pic.twitter.com/Hk7HLmMDra

Although SpaceX technicians managed to reassemble and install Mr. Steven’s net and arm fairing recovery mechanisms in just a handful of days, finishing less than 48 hours before the West Coast launch of SAOCOM 1A, the ship remained in port for the mission, passing up its fifth opportunity to attempt recovery of one of Falcon 9’s two fairings halves. Why exactly Mr. Steven never left port is unclear and unconfirmed, although SpaceX did mention that recovery would not be attempted this time around during its official launch webcast.
The most likely explanation is mundane – sea states with average swells as large as 4m (13ft) were forecasted (and later recorded) at and around the optimal fairing recovery zone. As a Fast Supply Vessel (FSV) explicitly designed to rapidly and reliably resupply oil rigs and other maritime work areas almost regardless of weather conditions, 4m waves would normally be a tiny pittance for ships as large and heavy as Mr. Steven and would be a nonsensical reason to halt deep-sea operations.

On the other hand, Mr. Steven is without a doubt the most unusual FSV in existence thanks to his massive arms and net, stretching at least 60m by 60m. Based on photos of the arm installation process, significant lists of 5+ degrees are not uncommon when arms are unbalanced during normal staggered (one-at-a-time) installations, and SpaceX quite clearly installs the first two arms on opposite sides and orientations in order to minimize installation-related listing. This indicates that his newest arms have significant mass and thus leverage over the boat’s roll characteristics, perhaps explaining why Mr. Steven has performed anywhere from 5-10 high-speed trials at sea both with and without arms installed.
Most recently, however, Mr. Steven spent a solid six weeks armless at Berth 240 while some sort of maintenance, analysis, or upgrade was undertaken with those four arms and their eight shock-absorbing booms. It’s hard to know for sure, but there are no obvious visual changes between the arms installed in July and August and those now present on his deck, and the net also looks almost identical.
Fairing drop tests?
What’s less familiar these days is an oddly arranged Falcon 9 payload fairing half that has been floating around SpaceX’s Port of Los Angeles berths for the last two or so weeks. Up until October 4th, the purpose of that single half was almost entirely unclear. On October 4th, Teslarati’s entire space team (Tom, Pauline, and I) coincidentally arrived at the same time as 5-10 SpaceX technicians were working on the fairing, attaching a series of guylines and harnesses and inspecting a number of actuating mechanisms on the half.
Just minutes after we arrived, a worker called out a short countdown and a wholly unexpected crashing noise sounded, followed immediately by several loud clangs as the harness connection mechanisms swung back and connected with metallic parts of the fairing. After the adrenaline wore off, the initial crashing noise was almost certainly the sound of the same mechanical jettison mechanism used to separate fairing halves ~3 minutes after the rocket lifts off.
Once photos of the event could be examined more carefully, that was exactly what we found – the six harness connections were attached to the fairing by way of the same mechanical interface that allows two halves to safely attach to each other. What we had witnessed was a harness separation test, using pressurized gas stored in COPVs (the gold striped cylinders) to rapidly actuate a latch, allowing the metal harness connectors to fall away. This is further evidenced by the presence of neon orange zip-ties connecting the ends of those harnesses to any sturdy fairing structure near the connection port, an easy and (presumably) affordable way to prevent those heavy connectors from swinging down and damaging sensitive piping and components.

According to someone familiar with these activities, the purpose of that testing is to prepare for true fairing drop tests from a helicopter. The jettisonable harness would be a necessity for easy drop testing, allowing the helicopter to carry a basic cargo hook and line while technicians inside communicate with the fairing to engage its built-in separation mechanism, all while ensuring that it immediately begins a stable glide or free-fall after dropping.
Observed on October 4th, it was at least moderately disappointing to see Mr. Steven remain in port during the spectacular Falcon 9 launch of SAOCOM 1A, October 7th. Reasons aside, roughly 12 hours after launch, Mr. Steven left on a 10+ hour cruise ~100 miles off the coast, where he repeatedly met up with tugboat Tommy and circled Santa Catalina Island once before heading back to port. Just 24 hours before launch (Oct. 6), the test fairing seen above was placed in Mr. Steven’s net for communications and harness testing – 24 hours after launch, Mr. Steven returned to Port of San Pedro after his 10-hour cruise with the same fairing half resting in his net.

How and why it got there is unknown, as is the purpose of half a day spent boating around with the half in his net. However, a helicopter known to be involved in fairing drop tests was seen hovering and flying around Mr. Steven at the same time. Perhaps the two were practicing for real drop attempts, or perhaps the helicopter actually dropped a Falcon fairing (from > 2000 feet) and Mr. Steven successful caught it.
What is clear is that SpaceX is just getting started with efforts to perfect fairing recovery and eventually make the practice as (relatively) routine as Falcon 9 booster recovery and reuse is today. The latter was hardwon and the former will clearly be no easier.

Tesla Model X shocks everyone by crushing every other used car in America
The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.
The Tesla Model X was the fastest-selling used vehicle in the United States in the first quarter of the year, crushing every other used car in America.
iSeeCars data for the first quarter shows that the Model X was the fastest-selling used car, lasting just 25.6 days on the market on average, two days better than that of the second-place Lexus RX 350h. The Cybertruck, Model Y, and Model S, in seventh, ninth, and thirteenth place, respectively, also made the list.
The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
Bringing closure to these two vehicles signaled the end of the road for the cars that have effectively built Tesla’s reputation for luxury and high-end passenger vehicles.
Relying on the sales of its mass market Model Y and Model 3, as well as leaning on the success of future products like the Cybercab, is the angle Tesla has chosen to take.
Teslas are also performing extremely well as a whole on the resale market. iSeeCars data shows that, “while the average price of a 1- to 5-year-old non-Tesla EV fell 10.3% in Q1 2026 year-over-year, the average price of a used Tesla was essentially flat at 0.1% lower across the same period. Traditional gas car prices dropped 2.8% during this same period.”
Additionally, market share for gas cars has dropped nearly 3 percent since the same quarter last year. Tesla has remained level, while the non-Tesla EV market share has increased 30 percent, mostly due to more models available.
Nevertheless, those non-Tesla EVs have seen their value drop by over 10 percent, while Tesla’s values have remained level.
Executive Analyst Karl Brauer said:
“Used electric vehicles without a Tesla badge have lost more than 10% of their value in the past year. This compares to stable values for Teslas and hybrids, and a modest 2.8% drop for traditional gasoline vehicles.”
Teslas, as well as non-luxury hybrids, are displaying the strongest resistance in the face of faltering demand, the publication says. But the more impressive performance is that of the Model X alone.
Tesla’s decision to stop production of the Model X may have played some part in the vehicle’s pristine performance in Q1. With the car already placed at a premium price point, used models are already more appealing to consumers. Perhaps second-hand versions were more than enough for those who wanted a Model X, and only a Model X.

Tesla Cybertruck’s head-scratching trim sold terribly, recall documents reveal
The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.
After Tesla decided to build a Rear-Wheel-Drive Cybertruck trim back in 2025, which was void of many features and only featured a small discount.
The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.
The recall deals with a potentially separating wheel stud and potentially impacts 173 Cybertruck units with the 18-inch steel wheels. The Cybertruck RWD was the only trim level to feature these, and the 173 potentially impacted units represent a portion of the population of pickups. Therefore, it’s not the entire number of RWD Cybertruck sold, but it could show how little interest it gathered.
The NHTSA document states:
“On affected vehicles, higher severity road perturbations and cornering may strain the stud hole in the wheel rotor, causing cracks to form. If cracking propagates with continued use and strain, the wheel stud could eventually separate from the wheel hub.”
Only 5 percent are expected to be impacted, meaning less than 10 units will have the issue if the NHTSA and Tesla estimates are correct. Nevertheless, the true story here is how terribly the RWD Cybertruck sold.
Tesla ended production and stopped offering the RWD Cybertruck to customers last September. For just $10,000 less than the All-Wheel-Drive trim, Tesla offered the RWD Cybertruck with just one motor, textile seats instead of leather, only 7 speakers instead of 15, no Rear Touchscreen, no Powered Tonneau Cover for the truck bed, and no 120v/240v outlets.
For just $10,000 more, at $79,990, owners could have received all of those premium features, as well as a more capable All-Wheel-Drive powertrain that featured Adaptive Air Suspension. The discount simply was not worth the sacrifices.
Orders were few and far between, and sources told us that when it was offered, sales were extremely tempered because customers could not see the value in this trim level.
Even Tesla’s most loyal supporters thought the offering was kind of a joke, and the $10,000 extra was simply worth it.

Tesla Semi sends clear message to Diesel rivals with latest move
The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.
Tesla has officially launched Semi production at what will be a mind-boggling rate of approximately 50,000 units per year.
The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.
The company finally announced on April 29 that the first Tesla Semi truck has rolled off its new high-volume production line at the factory. This marks the transition from limited pilot builds to scaled manufacturing for the Class 8 all-electric heavy-duty truck, nearly nine years after its dramatic 2017 unveiling.

Tesla initially promised high-volume deliveries by 2019–2020, but battery supply constraints and prioritization for passenger vehicles delayed progress. The new 1.7-million-square-foot factory, purpose-built next to Gigafactory Nevada’s 4680 cell production lines, resolves those bottlenecks through deep vertical integration.
The Semi uses Tesla’s structural battery packs with cylindrical 4680 cells manufactured on-site. This integration enables efficient supply, reduced logistics costs, and the potential for high output. The factory is designed for an eventual annual capacity of approximately 50,000 trucks, positioning Tesla to address growing demand in long-haul freight electrification.
Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
Operating economics favor the Semi through dramatically lower fuel and maintenance costs compared to traditional diesel rigs, and companies involved in a pilot program for the Semi with Tesla have shown that.
Electricity is far cheaper than diesel on a per-mile basis, while the electric powertrain features fewer moving parts, reducing service intervals and lifetime expenses. Early deployments with customers like PepsiCo and others have validated these advantages in real-world service.
The Nevada factory’s ramp-up is targeted for full volume output before the end of June 2026, aligning with broader Tesla production goals for 2026. This includes parallel efforts on other new vehicles while expanding the Megacharger infrastructure to support widespread adoption.
By localizing battery and truck production, Tesla gains advantages in cost, quality control, and scalability that many competitors sourcing cells externally lack. The start of high-volume Semi production represents a pivotal step in Tesla’s strategy to electrify heavy transportation, potentially accelerating the shift toward zero-emission freight across North America and beyond.
As output increases, the Semi could reshape long-haul logistics with its combination of performance, efficiency, and sustainability.
