SpaceX’s next Falcon Heavy rocket on track for early 2023 launch
Two weeks after SpaceX’s first Falcon Heavy launch in three and a half years, the US Space Force says that the rocket is on track to launch again “early next year.”
Immediately before and after Falcon Heavy’s first operational launch for the US Space Force, the Space Systems Command confirmed that the massive SpaceX rocket’s next military launch – USSF-67 – was scheduled no earlier than January 2023. The military also confirmed that USSF-67 would reuse two of the three Falcon Heavy boosters that helped launch USSF-44 on November 1st.
Two weeks later, the US Space Force’s tone hasn’t changed, and the Space Systems Command remains confident that Falcon Heavy is on track to launch USSF-67 less than three months after USSF-44.
Assuming the lack of a schedule change is intentional rather than a matter of not checking with SpaceX or other US stakeholders, no change is a good sign. Since the last time the SSC reported that USSF-67 was on track to launch in January 2023, SpaceX successfully launched its fourth Falcon Heavy rocket. USSF-44 was the company’s first launch directly into a geosynchronous orbit ~36,000 kilometers (~22,300 mi) above Earth’s surface.
SpaceX successfully recovered both of Falcon Heavy’s ‘side cores’ and has likely had enough time to thoroughly inspect each booster and begin the refurbishment process. If data gathered from the launch, landing, or recovered boosters uncovered issues with Falcon Heavy’s performance during USSF-44, USSF-67 would almost certainly be delayed. The chances of a delay are magnified by the fact that USSF-67 can’t launch until two of USSF-44’s Falcon Heavy boosters are refurbished and declared ready for a second flight.
-->But it appears that even a gap of 40 months between Falcon Heavy launches wasn’t enough to make SpaceX falter – at least after working out some prelaunch kinks. SpaceX accomplished a similar feat – launching two Falcon Heavy rockets in less than three months with one pair of side boosters – on the rocket’s second and third launches in April and June 2019. The mission that reused Flight 2’s side boosters was for the US Air Force, so SpaceX and the military already have direct experience tackling those challenges.
In the three and a half years since, SpaceX has gained a huge amount of experience recovering and refurbishing Falcon 9 Block 5 boosters and slashed its record turnaround (the time between two launches of the same booster) from 74 days to 21 days. SpaceX should thus have no issue turning Falcon Heavy side boosters B1064 and B1065 around for a second launch in January 2023, around 60 to 91 after their debut.
While preparing one Falcon Heavy rocket to launch USSF-67 in January, SpaceX – at least according to customer ViaSat – may also be preparing another Falcon Heavy rocket to launch the first ViaSat-3 satellite the same month. Unlike the US Space Force, which recently shipped [PDF] one of USSF-67’s payloads to Florida, ViaSat has yet to ship its first next-generation satellite to the launch site and says that milestone is scheduled for December 2022. That makes a February or March launch much more likely, but ViaSat recently told shareholders that ViaSat-3 remains on track to launch “in the earliest part of” Q1 2023.
Combined, USSF-67 and ViaSat-3 are scheduled to reuse Falcon Heavy side boosters B1064, B1065, B1052, and B1053. Each will use a brand new center core: B1068 for ViaSat-3 and B1079 for USSF-67, according to Next Spaceflight. Like USSF-44, which was the first time SpaceX intentionally expended a Falcon Heavy booster, both new center cores are expected to be expended.
For several reasons, assembling and preparing Falcon Heavy for launch is significantly more time-consuming than Falcon 9, so there will likely be at least a two, three, or even four-week gap between Falcon Heavy’s next two launches. But as long as USSF-67 and ViaSat-3 are ready to fly during narrow windows in early and late January, it appears that SpaceX could launch two Falcon Heavy rockets in one calendar month.
SpaceX has as many as five Falcon Heavy launches scheduled in 2023 – a stark change after more than three years without a single flight.

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.
