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

Why SpaceX is finishing another space-internet system that isn’t Starlink
SpaceX launched three final O3b mPower satellites Sunday, finishing a lesser known SES satellite network.
SpaceX had an 87 minute window opening at 2:49 p.m. Eastern on Sunday to fly a Falcon 9 out of Cape Canaveral carrying the final three satellites for SES’s O3b mPower constellation, a project that has taken more than a decade to finish since Boeing and SES first signed SpaceX on for the work.
Unlike the thousands of Starlink satellites SpaceX has stacked into orbit over the years, O3b mPower flies in a different neighborhood entirely. The three new satellites, tagged F11, F12 and F13, are headed for medium Earth orbit at roughly 5,000 miles up, more than ten times higher than Starlink’s shell around 340 miles but still a small fraction of the 22,000 miles where old school geostationary satellites sit. That middle position is the whole point, because a satellite that far out needs far fewer siblings to blanket the globe than a low orbit constellation does. Essentially, SES only needed 13 satellites total to build a network offering quick, steady service that used to require thousands of spacecraft.
With most people having heard plenty about Starlink and almost nothing about O3b mPower, SES and SpaceX already blend the two networks for some customers. Both SpaceX and SES sell satellite broadband, but they’re aimed at different buyers. Starlink is built for volume, direct to consumers, RVs, homes, small businesses, plus a growing aviation and maritime business. O3b mPower skips consumers entirely and sells enterprise grade connectivity to airlines, cruise lines, offshore energy operators, telecoms needing backhaul, and governments, priced and provisioned more like a dedicated circuit.
A 2023 partnership lets cruise ships combine Starlink’s speed with O3b mPower’s steady capacity depending on what a ship needs at a given moment. Sunday’s completed 13 satellite constellation effectively finishes the medium orbit half of that pairing, years after.
Sunday’s mission was already a something on SpaceX’s manifest well before O3b mPower entered the picture. This flight marked its 29th trip to orbit, a history that includes two crewed Axiom missions, the European Space Agency’s Euclid telescope and 22 separate Starlink batches. SpaceX has landed boosters on the droneship A Shortfall of Gravitas so often that Sunday’s touchdown attempt, if it went as planned, was set to be the 661st successful Falcon booster landing to date.
For a company that pushed the Starlink constellation past 11,000 satellites back in August, almost entirely through bulk launches from California, Sunday’s flight was a reminder that SpaceX’s schedule still has room for someone else’s satellites too. SES gets a finished network built for a narrower set of customers, and Falcon 9 gets one more line on an already long resume.

Tesla gives the Roadster an official “Go for launch” demonstration date
Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.
Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.

Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.
The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.
Tesla Roadster SpaceX Package’s 1.1-second 0-60 mph launch visualized in concept video
Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.
The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.

Tesla plans big safety improvements for Full Self-Driving v15
Tesla is planning to roll out some pretty significant safety and accident avoidance features with Full Self-Driving version 15, which will be the next major FSD deployment from the company.
Tesla AI lead Ashok Elluswamy used a near-miss this week to preview what the company says is the next leap in Full Self-Driving.
In response to a driver whose car had swerved away from another vehicle pulling out of a parking lot, Elluswamy wrote that he was glad the owner was safe and that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” would arrive with FSD v15.
Glad you are safe. Even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance coming as part of the next big upgrade (v15).
— Ashok Elluswamy (@aelluswamy) September 11, 2026
The comment landed as Tesla continues to treat software as the primary safety upgrade path. v15 is described internally as a larger architectural step, with a much bigger neural network and tighter coupling between prediction and control.
The company has already begun using early v15 software in some robotaxi operations while rolling out safety features such as Automatic Collision Evasion into current customer cars, allowing the driving stack to intervene even when the driver is in manual control.
Tesla is rolling out a new FSD version with a massive safety addition
Tesla’s published telemetry is the backbone of its safety argument. In recent North American Vehicle Safety Report data, vehicles with FSD (Supervised) engaged traveled roughly 5.1 million to 5.7 million miles between major collisions, defined as airbag-deployment events.
Tesla’s estimate of the U.S. average over the same period is about 699,000 miles per comparable crash. That is the comparison Tesla often frames as roughly seven times fewer major collisions.
A tighter comparison uses the same Tesla fleet. Cars driven manually with active safety features such as automatic emergency braking still recorded a major collision about every 2.1 million miles. Against that baseline, FSD’s advantage shrinks to roughly 2.4 to 2.7 times fewer severe crashes, which independent researchers argue is the more apples-to-apples figure.
European data released in 2026 pointed in the same direction: Tesla reported FSD as 3.5 times safer than manual driving in the Netherlands and 4.1 times fewer collisions than manually driven Teslas with active safety across more than 100 million kilometers in five approved countries.
Those numbers do not settle every debate. NHTSA’s Standing General Order still shows Tesla accounting for the large majority of U.S. Level 2 driver-assist crash reports, in part because the fleet logs far more assisted miles than rivals. Critics also note that Tesla’s “U.S. average” mixes crash definitions and driving mix.
Even so, Tesla’s own same-car comparisons, plus lower rates of automatic emergency braking and harsh maneuvers when FSD is engaged, are the evidence Elluswamy is pointing to when he says v15 will push prediction and collision avoidance further. The claim is not that software already eliminates risk. It is that each major version is meant to widen the gap between the system and an unaided human driver.
