SpaceX schedules second Starship static fire after first test ends prematurely
Update: SpaceX appears to have plans for a second triple-Raptor static fire for Starship SN9 after the rocket’s first test was cut short for unknown reasons.
Identical to previous road closure windows, SpaceX will have an opportunity to test Starship SN9 from 8 am to 5 pm CST (UTC-6) on Friday, January 8th, potentially paving the way for a high-altitude launch attempt early next week if the second static fire goes as planned. Stay tuned for updates!
In what is likely one of the last steps before SpaceX’s next high-altitude Starship launch attempt, the company appeared to successfully put Starship serial number 9 (SN9) through its first triple-Raptor static fire test.
Relatively late into a test window that opened at 8 am CST (UTC-6) but was later pushed to noon, SpaceX’s first Starship SN9 static fire attempt began in earnest around 3:15 pm CST. Signified by venting activity at the propellant farm tasked with preparing and loading liquid oxygen and methane on Starships, slight tweaks in the test flow were observed but the static fire occurred more or less when expected at 4:07 pm.
SN9 ignited all three of its Raptors in quick succession and shut the engines down over the course of 1.5-2 seconds – extremely short relative to all previous nominal Starhopper or Starship-mounted Raptor static fires. Long-time followers immediately noted that small discrepancy, speculating that it could either have been a post-ignition abort or intentionally shortened to avoid damaging the pad’s concrete surface (an incident that’s occurred several times during recent tests).
-->Not long before the short static fire, SpaceX extended the end of its January 6th test window (in the form of road closure notices) from 5 pm to 8 pm. Oddly, rather than the expected response of detanking Starship and reopening the road after a successful test, SpaceX essentially recycled SN9 and began a separate test around 6 pm. The road was never reopened and a SpaceX team never headed back to the pad between the tests, implying that the company may have run into a minor hardware or software bug earlier in the day.
It’s unclear what the actual goal of the second attempt was and it’s more or less impossible to know for sure with confirmation from CEO Elon Musk. It’s possible – if unlikely – that the first static fire went exactly as planned and the follow-up test was meant to be a simple data-gathering wet dress rehearsal (WDR). Either way, after a surprise downpour briefly engulfed Starship SN9 minutes prior, the second test appeared to abort about 30 minutes into propellant conditioning and loading, precluding both a complete WDR and/or static fire.
According to a test notice received on January 6th by NASASpaceflight contributer and photographer Mary (bocachicagal), SpaceX has another test window available on January 7th in the event that Wednesday’s testing was partially unsuccessful. In a rare case, SpaceX’s hand-distributed warning for residents preceded any additional planned road closures, the last of which lifted on January 6th.
On January 5th, SpaceX received a trio of Temporary Flight Restrictions (TFRs) from the FAA that will allow the company to restrict access to nearby airspace for high-altitude Starship launch attempts on January 8th, 9th, and 10th. Lacking an unequivocally successful static fire, it’s highly unlikely – but not impossible – that Starship will be ready for a launch attempt during any of those three windows. Still, it’s safe to say that SN9 is probably less than a week away from its first flight – expected to be a carbon copy of SN8’s 12.5 km (7.8 mi) launch and landing attempt – if SpaceX can complete a full-duration static fire in the next day or two.

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.
