SpaceX completes Falcon 9 test fire, space station supply mission up next
After almost exactly 15 months of dormancy, SpaceX’s Launch Complex 40 (LC-40) came to life with the roar of nine Merlin 1D rocket engines as Falcon 9 1035 conducted its second pre-launch static fire in preparation for the company’s 13th Commercial Resupply Services mission, CRS-13. Previously tasked with the launch of the CRS-11 Cargo Dragon, the booster completed its mission and returned safely to Landing Zone-1 (LZ-1) on June 3 2017. The path towards LC-40’s reactivation has delayed the launch approximately one week, but December 6th’s successful static fire bodes well for the current launch date, 11:46 AM on December 12.

On September 6 2016, LC-40 was effectively destroyed over the course of the Amos-6 failure. In months that followed, SpaceX reactivated LC-39A in order to continue chipping away at the company’s launch manifest, but also began the slow process of damage assessment and reconstruction of LC-40. It is safe to assume that almost every single component of the ground support equipment (GSE) was completely replaced, and interviews with Cape Canaveral’s 45th Space Wing commander suggest that SpaceX went further still, transforming the painful situation into an opportunity.
In an exclusive and frank conversation between Brig. Gen. Wayne Monteith and Florida Today’s Emre Kelly, the commander suggested that extensive design changes and additional hardening measures implemented during reconstruction are expected to make LC-40 exceptionally resilient to the rigors of rocket launches. Most tellingly, if perhaps overly optimistic, Monteith estimated that a second vehicle failure on the order of Amos-6 might only take two months to recover from, compared to the 15 months that followed Amos-6. He attributed this claim to GSE that is now largely buried underground, theoretically protecting the vast apparatus of hand-welded piping necessary to fuel the Falcon 9 launch vehicle. The replacement Transporter/Erector/Launcher (TEL) tasked with supporting Falcon 9 during integration and launch also appears to have been modernized, and will likely end up looking quite similar to the monolithic white TEL that resides at LC-39A.

With CRS-13’s static fire now complete, the mission is set to become the fifth operational reuse of a flight-proven Falcon 9 booster in 2017, thanks to NASA’s unusually rapid acceptance of the new practice. Further still, if Iridium-4’s December 22 launch date holds, and it does look to be stable for the moment, SpaceX will rather incredibly have conducted five commercial reuses of a Falcon 9 in its first year of operations, meaning that one third of SpaceX’s 2017 missions will have launched aboard flight-proven boosters. Also impressive is SpaceX’s full-stop move towards the reuse of Cargo Dragon capsules, and the company stated over the summer that it was hoping to almost completely redirect Cargo Dragon’s manufacturing facilities towards Dragon 2, also known as Crew Dragon. This was most recently reiterated several months ago and is presumed to still be the company’s goal moving forward, and CRS-12 is believed to have been the last “new” Cargo Dragon that will fly. CRS-13’s Dragon previously flew the CRS-6 mission in April 2015.

In a December 6 tweet, SpaceX further confirmed that the deeply secretive Zuma mission, previously delayed from an early-November launch as a result of concerns about fairing defects, has now been moved from LC-39A to LC-40 and is understood to be targeting January 4 2018. This will give SpaceX approximately three weeks after the launch of CRS-13 to verify that everything is functioning nominally in what is essentially a new pad.
Meanwhile, with Zuma now officially moved to 40, LC-39A is completely free from routine operations, meaning that SpaceX’s ground crew can now work at will to ready the pad for the inaugural launch of Falcon Heavy, now aiming for early 2018. Aside from Falcon Heavy, recent FCC filings point to two additional SpaceX launches aiming for January, although slips are probable in light of CRS-13’s minor delays. Regardless, December and January are likely to be thrilling months for followers of the intrepid space exploration outfit.

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.
