SpaceX’s successful debut of Falcon 9 Block 5 heralds the future of reusable rocketry
Following a brief software bug-triggered abort during the first attempt, SpaceX has successfully debuted its first Falcon 9 Block 5 rocket from Florida’s Kennedy Space Center, marking the true beginning of a new era of highly reusable commercial rocketry, as well as Bangladesh’s official entry into satellite communications with the Bangabandhu-1 satellite.
Followed minutes later by the first landing of its next-generation booster aboard the ocean-going drone ship Of Course I Still Love You (OCISLY), many more Falcon 9 Block 5 launches can now be expected to follow later this year as SpaceX ramps up the manufacture and shipment of new boosters, upper stages, and payload fairings to its test and launch facilities.
Fundamentally, this launch is a historic achievement for SpaceX. According to CEO Elon Musk, barring unforeseen discoveries during the pathfinder booster’s post-recovery teardown, Falcon 9 Block 5 as it stands today is nearly capable of ushering in a new era of truly reusable rockets, and is designed to (nominally) fly as many as ten times in a row with the barest minimum of refurbishment. While it is all but guaranteed that small optimizations and upgrades will continue to be made throughout the launch vehicle, today’s mission – the 25th successful booster landing and 55th launch of Falcon 9 – by all appearances successfully flight-tested almost every single one of the rocket’s dramatically upgraded systems, ranging from entirely new avionics to uprated and upgraded Merlin engines and landing legs.

Somewhat fittingly, the only problem visible on the company’s webcast of the rocket’s critical debut was with the webcast itself, in the form of some odd shaking and connectivity issues on the first stage (and the second stage to a lesser degree). Thankfully, this “bug” is skin-deep – its only negative impact was mild annoyance among the many thousands watching live, a small price to pay to such an extraordinary show. Falcon 9 B1046 and its upper stage performed nominally, landing aboard the drone ship Of Course I Still Love You and flawlessly placing Bangladesh’s first geostationary communications satellite into a transfer orbit.

With its debut complete, SpaceX’s first Block 5 booster will now head back to Port Canaveral after being safely secured by everyone’s favorite rocket-grabbing robot. After its return to land, it’s extremely likely that SpaceX will choose to transport the rocket back to either Hawthorne or McGregor to conduct an extremely thorough teardown analysis of the booster, checking to ensure that each component and system made it through a high-energy reentry with minimal impact. While small changes are all but guaranteed, this teardown will hopefully confirm SpaceX’s extensive modeling and ground-testing – in other words, Block 5’s design will hopefully be shown to be ready for rapid reusability and extreme reliability. More likely than not, B1046 will then be reassembled, perhaps followed by extensive static-fire testing in Texas, after which it will likely return to SpaceX’s operational rocket fleet, potentially conducting dozens of launches over the next several years. Perhaps SpaceX will choose to turn it into a new historic monument after several reflights.
-->Finally, congratulations to Bangladesh on the successful launch of their first geostationary communications satellite.

Launch photographer Tom Cross is planning to be there in person for OCISLY and B1046’s arrival in Port, and will hopefully be able to document the historic recovery and the booster’s (fingers crossed) resilience, as well as the first use of Octagrabber with a Block 5 Falcon 9. Remote camera pickup is currently scheduled for tomorrow morning.

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.
