SpaceX delays Starlink launch after Falcon 9 static fire test
Around 10 am Pacific on November 17th, SpaceX test-fired one of its Falcon 9 rockets and announced that its next Starlink launch would follow as early as Friday, November 18th. Seven hours later, SpaceX canceled those plans, stating that it needed “to take a closer look at data” gathered during the test.
Next Spaceflight reports that Falcon 9 booster B1061 is assigned to the launch, making it responsible for the static fire portion of Thursday’s launch rehearsal. B1061 is one of six Falcon boosters that has completed ten launches and will become either the fourth or fifth to launch 11 times (or more) when it launches SpaceX’s Starlink 2-4 mission. But after SpaceX’s unusual post-test announcement, the rocket and its Starlink payload will have to wait indefinitely while the company determines how to proceed.
It’s not the first time SpaceX has delayed a launch indefinitely after a static fire test, but it is the first time in years. SpaceX semi-regularly stands down from launch attempts to conduct inspections or complete minor repairs or component replacements when data is amiss or contradictory, but those plans tend to mention the next launch target. This time, even SpaceX’s website has been scrubbed to say that “a new target launch date [will be announced] once confirmed.”
The last time a prelaunch static fire was explicitly blamed for a launch delay was in August 2019, when SpaceX fired up a Falcon 9 rocket ahead of its Amos-17 launch, didn’t like what it saw, decided to replace a valve on the booster, and then conducted a second static fire test to clear the rocket to launch. It’s possible that Starlink 2-4’s sequence of events will end up being similar.
Airspace closures indicate that Starlink 2-4 had already been delayed multiple times, missing targets on November 16th and 17th to November 18th.
-->Whenever it does launch, Starlink 2-4 will be SpaceX’s 65th operational Starlink mission, and is scheduled to add another 52 Starlink V1.5 satellites to the constellation’s Group 2 shell. Group 2 is the third largest of five shells that make up SpaceX’s first 4408-satellite Starlink constellation and will have 720 satellites once completed. SpaceX has nearly finished two main 1584-satellite shells that orbit over Earth’s mid-latitudes. It’s also begun launching one of two smaller shells (Group 3 and 5) that orbit Earth’s poles. Group 2 splits the difference with an orbit inclined 70 degrees relative to Earth’s equator.
According to data collated by astrophysicist Jonathan McDowell, and assuming that SpaceX intends to have as many satellites in orbit as possible, Group 1 and Group 4 appear to be four or five launches away from completion. Group 3 and 5 require eight more launches. Including Starlink 2-4, Group 2 will take another 13 launches. Barring surprises, SpaceX has approximately 25 launches left to complete its first Starlink constellation. In the first ten months of 2022, SpaceX launched 32 operational Starlink missions, and its launch cadence has increased throughout the year, boding well for the constellation’s completion by mid-to-late 2023.

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.
