SpaceX Falcon 9 booster nails record fourth launch and landing during Starlink-1
For the first time ever, SpaceX has successfully launched and landed the same Falcon 9 booster on four separate orbital-class missions, pushing the rocket’s Block 5 upgrade one step closer to realizing its ambitious design goals.
After an unprecedented lull of more than three months between launches, SpaceX has successfully returned to flight with its internal Starlink-1 mission, simultaneously crossing off multiple rocket reusability milestones. In terms of value added, Falcon 9 booster B1048’s reflight was the most important non-satellite achievement of the mission.
Impressively, B1048 has now successfully launched and landed on four separate occasions, a first for all Falcon 9 or Heavy boosters. Some nine minutes after lifting off from Cape Canaveral, Florida’s LC-40 launch pad, B1048 came to a gentle, near-bullseye halt aboard drone ship Of Course I Still Love You (OCISLY), stationed some 630 km (340 mi) northeast of the Florida coast.
With the successful completion of Starlink-1, B1048 alone has now collectively supported the launch of more than 35 metric tons (77,000 lb) into Earth orbit, as well as the first attempted (but sadly unsuccessful) commercial Moon landing attempt as part of its third launch in February 2019. This particular tidbit is noteworthy because it likely makes B1048 the first Falcon 9 booster to help orbit more than twice the payload mass it would otherwise be capable of launching in a single mission, an impressive reminder of the game-changing success of SpaceX’s reusable rocketry development.
Even then, B1049 is likely close on B1048’s heels – if not already ahead of the booster – in terms of the mass of satellites it has singlehandedly helped to place in orbit.

Aside from Falcon 9 B1048’s historic fourth launch and landing, Starlink-1 also marked the first time SpaceX has launched a flight-proven payload fairing, a huge step towards ensuring that nearly all future Falcon launches are up to 80% flight-proven and 80% reusable. Starlink-1’s payload fairing previously flew on Falcon Heavy Block 5’s Arabsat 6A launch debut back in April 2019, essentially a worst-case scenario for fairing reuse.
That successful reuse in spite of the fairing’s exceptionally extreme launch and recovery conditions suggests that almost any fairing recovered in the future will capable of at least one reuse, be it on internal Starlink missions if not customer launches. CEO Elon Musk has previously indicated that Falcon 9 (and Heavy) fairings represent approximately 10% of the cost of Falcon 9 launches, meaning that each set of halves has a price tag of roughly $6 million. Additionally, it’s believed that Falcon fairing production has some of the longest lead-time aspects of any aspect of SpaceX rocket manufacturing, to the point that fairings could easily become a bottleneck for launch cadence without expensive production facility upgrades.
Instead, SpaceX may have chosen to spend a similar amount of time and money making Falcon fairings routinely recoverable and reusable. That program crossed a turning point in June and August 2019, when fairing recovery ship GO Ms. Tree (formerly Mr. Steven) successfully caught two fairing halves in a row, unequivocally proving that the challenging catches are repeatable. Three months later, November 11th’s Starlink-1 launch has also proven that fairings can be reused even without a successful catch, meaning that it will likely be far easier and far more viable to reuse fairings that have been saved from ocean baths.
Unfortunately, SpaceX had to call off an attempted dual recovery of both fairing halves and GO Ms. Chief’s first operational catch attempt due to high seas in the recovery area. Prior to her remaining, similar sea conditions destroyed and broke off two of Mr. Steven’s arms while traveling to the recovery area, and SpaceX has clearly learned from that experience.

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.
