SpaceX’s new Falcon 9 fairing recovery ship kicks off sea trials ahead of next launch
After a brief installation period, SpaceX’s second Falcon 9 fairing-catching ship departed Port Canaveral to begin sea trials with its new net and arms, a critical step before it can be declared ready to attempt its first fairing recovery.
Known as GO Ms. Chief, the ship’s first opportunity could come as early as a few weeks from now, potentially marking a major milestone for SpaceX’s fairing recovery and reuse program.
On his first shoot for Teslarati, photographer Richard Angle (@RDAnglePhoto) managed to capture Ms. Chief while departing Port Canaveral on October 23rd, heading a few miles off the coast to kick off sea trials likely focused on proving out a wide range of new hardware installed in the last month. Those trials began less than 24 hours after technicians installed Ms. Chief’s recovery net for the first time ever, with the ship’s subsequent trip into the Atlantic Ocean essentially marking the completion of her transformation from fast supply vessel (FSV) to SpaceX fairing catcher.
SpaceX is currently in the midst of its longest lull in launch activity since September 2016, likely triggered by the unavailability of customer payloads and the company’s own internal Starlink missions. Unfortunately, although the lull was initially expected to end as early as mid-October, the internal Starlink launch (Starlink-1) expected to lead the charge slipped about a month for unknown reasons and is now expected no earlier than November – likely in the second half of the month.
As a small consolation, Starlink-1’s launch delays mean that the newly-outfitted Ms. Chief may be able to inaugurate its new net and arms by attempting to recover one of the mission’s Falcon 9 fairing halves, while the nearly identical GO Ms. Tree attempts to snag the other half. Even if more tweaking and sea trials are needed to prove her readiness, SpaceX’s next launch is still likely several weeks away, hopefully giving the company’s recovery team plenty of time to prepare Ms. Chief and practice recovery operations.
As of October 2019, SpaceX has successfully caught two Falcon fairing halves during the company’s last two back-to-back recovery attempts, beginning with a Falcon Heavy fairing half caught on June 25th and ending with a Falcon 9 fairing half caught on August 7th. Beyond Ms. Tree’s two catches, SpaceX has successfully recovered a number of additional fairing halves after they performed soft landings in the Atlantic Ocean, including both halves launched in May 2019 for the company’s first dedicated Starlink mission.
Given that SpaceX has technically caught two halves of a payload fairing, it’s possible that one is female and the other male, potentially meaning that one of SpaceX’s upcoming Starlink launches could feature the first fully-reused Falcon 9 fairing. Regardless, assuming one or both were recovered in good condition, it’s even more likely that at least one half (with the other half new) will be reused on one (or both) of those upcoming flights.
Said by CEO Elon Musk to make up approximately 10% of the cost of a new Falcon 9 (~$6M), routine fairing recovery and reuse would close the last remaining loop for Falcon 9 reusability, with boosters and fairings accounting for roughly 75-80% of the total cost of the rocket. SpaceX has no plans to attempt to recover or reuse Falcon 9’s second stage, choosing instead to prioritize development of the fully-reusable Starship launch vehicle.
Preparing the oven-cured carbon composite shells that make up the bulk of SpaceX’s Falcon fairings takes a disproportionate amount of time and factory floor space. Even if Falcon fairings can only be reused once or twice, it would effectively double or triple the effectiveness of the current manufacturing apparatus, cutting the relative cost of production by 50% or more for the price of operating Ms. Tree and Ms. Chief.
-->Fairing reuse will be a critical part of ensuring that the first phase of SpaceX’s Starlink constellation can be launched as affordably as possible on Falcon 9. With at least 24 launches needed to cover most populated areas, cutting even a few million dollars per launch could produce savings on the order of $100M, equivalent to the production cost of 100-200 Starlink satellites.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
