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.

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.
- Mr. Steven returned to Port of San Pedro around 7pm on October 8th after a day spent at sea, apparently with a Falcon fairing half in tow. This is the second known time that a fairing has been in Mr. Steven’s net. (Pauline Acalin)

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 Cybercab and Robotaxi’s real advantage won’t be the ride service
For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.
Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.
Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.
Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant
Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.
This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?
If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.

Why Elon Musk’s target date for buying an Optimus robot is harder than it sounds
Musk says China’s magnet export ban cost Optimus months, and robot hands remain shockingly hard.
Elon Musk says China’s export curbs on magnets used in electric motors set back Tesla’s Optimus program by two to three months, and that the robot’s hands remain the hardest part of the project. He made the comments Saturday during a live interview with Tesla Owners Silicon Valley at the X Takeover event at Giga Texas, in front of roughly 2,000 attendees. The Optimus discussion begins around the 49 minute mark of the stream.
On the hands, Musk was blunt and noted that a general purpose humanoid needs fine motor skills that are “incredibly difficult to get right. Shockingly difficult,” he said in the interview. He pointed to a problem he says no one has demonstrated yet: “One of the hardest things also generally is to do precision and force at the same time,” such as driving a small self tapping screw into wood. Touch sensors add another layer, since it is “actually kind of hard to get touch sensors that elastically deform and can handle high cycle life and it won’t just break after a few thousand cycles.”
He also took aim at rival robot videos. “Any complicated looking robot demo, it’s a canned demo. It’s not real,” Musk said, adding that real AI means showing a robot something it has never seen and watching it still cope, the way FSD handles a city it has never driven.
Musk expects the Optimus ramp to be slower than a new vehicle production ramp. “The initial part of that S curve of production ramp is going to be very slow at the beginning,” Musk said, partly because “unlike cars, there’s no pre existing supply chain for robot stuff.” That echoes his July reply on X that Optimus production “will be extremely slow at first, as everything is new.”
The magnet disclosure puts a number on a problem Musk first raised in 2025. He said China “prevented the export of magnets for use in electric motors” and that it “set back the Optimus program by like two or three months.” Then he added: “We had robots with no arms.” Tesla’s fix is to bring the supply chain home. “You’ve got to be able to make all the parts domestically,” he said. Teslarati reported in April 2025 that Musk tied the issue to permanent magnets in the arm actuators, where motors have to be as small as possible.
Tesla Optimus V3 hand and arm details revealed in new patents
Production is moving regardless, with a reported internal goal of more than 1,000 a week by the end of 2026. Teslarati recently covered how Tesla is certifying supply partners in China for Optimus parts, while the company’s hand design has been the subject of new patent filings.
Musk has said he wants Optimus available to the public by late 2027, though Tesla has not confirmed that date or published updated production figures.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet
Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.
Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”
That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”
“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.
Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”
The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”
The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.
NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.
One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.
