SpaceX Falcon fairing recovery vessel Mr. Steven tests out new limbs at sea

Mr. Steven took to sea to test out a new recovery-related appendage - purpose unknown - on November 12. (Pauline Acalin)

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).

Tesla’s mysterious Robovan makes a sneak peek with Optimus in Terafab video

Elon Musk shared a new Terafab video showing Optimus, Robovans, and a stunningly futuristic campus.

SpaceX Terafab rendering

Elon Musk posted a new video of Terafab on X Thursday morning, and the most eye-catching details in it were not the building itself, but two products still awaiting production: Optimus and the Robovan.

The concept render, credited to SpaceX, shows Optimus robots working the grounds of the roughly 2.5-mile-long facility planned for the Gibbons Creek site in Grimes County, while a Robovan glides along an elevated roadway cutting through the building itself, sharing the frame with a Tesla Semi and a Cybercab.

Robovan is the boxy, driverless people and cargo mover Musk unveiled alongside Cybercab at Tesla’s “We, Robot” event in October 2024. He pitched it as a way to move up to 20 passengers at once, or handle freight instead, at a target cost he claimed could fall under a dollar a mile, with no steering wheel or pedals, the same layout as Cybercab. Nearly two years later, Robovan still has no confirmed production timeline and has not shown up in any factory footage, which makes Thursday’s render one of the only recent looks at the vehicle in any form.

Optimus has moved further along. Tesla began converting Fremont’s old Model S and Model X assembly line into a Gen 3 Optimus production line earlier this year, and Musk visited the site on July 1 to mark the changeover. A second, larger Optimus plant is under construction at Giga Texas, targeting volume production in summer 2027 and eventual capacity of 10 million units a year. Tesla AI lead Ashok Elluswamy said this month the robot has “big shoes to fill” in replacing the S and X line, while Musk has repeatedly called Optimus the company’s biggest product of any kind, with a long-term price he has pegged between $20,000 and $30,000.

“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote alongside the clip. “And it will be stunningly beautiful.”

One quote post summed up the reaction: “Futuristic scene with RoboVan + Cybercab + Tesla Semi + Optimus.”

Beyond the vehicles, the architecture wrapped around them stands out too. The building’s facade is canted at sharp angles, with illuminated horizontal bands running through what appears to be a multi level interior visible from outside. Below the elevated roadway, pedestrians walk along a plaza next to a reflecting pool, and the skyline behind the campus is dotted with angular spires that read more like sculpture than infrastructure, a departure from the strictly utilitarian look of Gigafactory Texas or Starbase.

The timing tracks with what Terafab representative Riley Trennell told Grimes County residents on Wednesday, when he said renderings of the facility would be released “within days.” Musk’s post followed less than 24 hours later, and Texas Governor Greg Abbott’s office sent out its own release Thursday confirming the project. As Teslarati reported this morning, Terafab’s tax abatement agreements with Grimes County are now signed and active, and SpaceX has sent the county its first $10 million payment under that deal. The dollar figure tied to this phase of construction, per Reuters, is $16.8 billion, one of the first hard capital expenditure numbers attached to Terafab since Musk unveiled the joint Tesla-SpaceX-xAI venture in March.Reaction on X ranged from enthusiastic to skeptical. “God Bless Texas! Everything is bigger and better in Texas!” one reply read. Another was more measured: “Terafab in a decade…..”

Whether the finished building matches the render is a separate question from whether Musk wanted people talking about the render itself. Less than a day after posting, the video had already crossed 5.5 million views.

Tesla Cybertruck production snaps back after ugly supplier fight

Tesla Cybertruck production resumes after supplier dispute: Credit: Joe Tegtmeyer | Youtube

Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.

Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.

Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.

Tesla quietly made the Cybertruck even stronger

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.

Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.

The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.

Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry

Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.

SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.

Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
