SpaceX’s upcoming Starlink launch will set a record for Falcon 9 booster reuse
SpaceX’s next launch will fly on a Falcon 9 Block 5 booster with three flights in its history, making the mission the first time SpaceX will launch the same orbital-class booster four times.
Likely attributable to a number of launch customers all coincidentally not ready for flight, SpaceX is in the midst its longest lull between launches since September 2016, three years ago, when Falcon 9 suffered its most recent catastrophic failure. During the lull, SpaceX COO and President Gwynne Shotwell noted that this is the first time in SpaceX’s history where the company is waiting on customers to launch, rather than the other way around.
That lull – currently past the two-month marker – is hoped to end sooner than later, although SpaceX’s ‘return-to-flight’ mission has become more uncertain in the last few weeks. For unknown reasons, the schedule for SpaceX’s next Starlink mission(s) went from having fairly specific launch targets (October 17th and November 4th) to more unclear schedules. Currently, SpaceX’s next launch will likely be the first flight of 60 Starlink V1.0 satellites and is expected no earlier than late-October or November.
Depending on how far right the mission moves on that schedule, SpaceX’s next launch might instead be a more regular commercial satellite mission, Kacific 1, scheduled for launch no earlier than (NET) November 11th.
Regardless of which mission actually comes next, speaking earlier this at the 2019 National Academy of Engineering annual meeting, SpaceX VP of Build and Flight Reliability revealed that “the next launch” will mark the first time a Falcon 9 booster has launched four times. As of now, SpaceX has launched four separate Falcon 9 boosters three times apiece, beginning with B1046 in December 2018 and ending most recently with B1047 in August 2019.
According to CEO Elon Musk and other SpaceX executives and employees, Falcon 9 Block 5 boosters are designed to fly no fewer than 10 times apiece before requiring substantial refurbishment. SpaceX has three (B1047 was expended on its third flight) thrice-flown Falcon 9 Block 5 boosters on hand, all of which can thus be assumed to be ready for another mission. In fact, B1046.3 is known to be assigned to SpaceX’s imminent Crew Dragon In-Flight Abort (IFA) test (NET November 23rd).
This leaves B1048 and B1049 as SpaceX’s booster options for their next launch. Assuming it’s a Starlink, it seems likely that B1049 would be the booster of choice, as that particular booster supported SpaceX’s first Starlink v0.9 launch back in May 2019. On the other hand, Falcon 9 B1048 completed its third launch in February 2019, meaning that it has had more time for post-flight inspections and (minimal) refurbishment, although it’s entirely unclear what sort of timescales SpaceX is currently operating on for Block 5 booster reuse.
Regardless of the specifics, SpaceX’s plans for a prolific number of internal Starlink launches will create a huge number of opportunities for the company to test new hardware/software and push the envelope of reusability, all without having to convince paying customers to be the guinea pigs. Once SpaceX has pushed its booster fleet onto their fourth flights, Starlink missions can easily take the reins and prove the safety of five-flight Falcon 9s and beyond.

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.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. 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-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
