Watch SpaceX’s last launch and landing of 2020 live [webcast]
Update: Despite no plans for a preflight static fire, SpaceX remains on track to attempt its last launch and landing of 2020 as early as 9 am EST (14:00 UTC), Thursday, December 17th.
After performing a routine preflight wet dress rehearsal (WDR) and booster static fire prior to every launch since September 2016, SpaceX has gradually begun to loosen the requirement for flight-proven rockets in 2020. Instead, if a prior flight or post-flight inspection reveal issues, static fires will serve more as a data-driven diagnostic tool. For flight-proven boosters with a clean bill of health, so to speak, SpaceX appears to be confident enough to skip the procedure on a few internal Starlink launches and the odd customer mission.
Now, despite NROL-108 begin the NRO’s first direct launch contract with SpaceX and first flight on a flight-proven Falcon 9 rocket of any kind, let alone the four-flight booster assigned to support it, the espionage agency apparently has equal faith in SpaceX. Falcon 9 B1059, a new upper stage and payload fairing, and the unspecified NROL-108 payload(s) went vertical at Kennedy Space Center (KSC) Launch Complex 39A on December 16th – far too late for any WDR or static fire testing prior to an early December 17th launch attempt.
The mission will be SpaceX’s 26th and final launch of 2020 and – barring a major surprise – the last orbital US launch of the year. As usual, SpaceX will broadcast the launch live, with coverage beginning around 15 minutes prior to liftoff (8:45 am EST/UTC-5).
The National Reconnaissance Office (NRO) says that SpaceX remains on track to attempt its last Falcon 9 launch and landing of the year after an almost two-month delay.
Originally scheduled to launch as early as October, the secretive orbital espionage agency’s NROL-108 launch plans were quietly revealed in routine communication permission requests filed by SpaceX with the FCC. Unfortunately, those plans came around the same time as a Falcon 9 booster engine issue aborted a SpaceX launch at the last second and forced the company to undergo a quick but extensive anomaly investigation. As it turns out, the Falcon 9 booster assigned to support NROL-108 (B1059) was practically siblings with the three new boosters affected by the investigation.
-->SpaceX may have had to swap some of the nine Merlin 1D engines on B1059, although a far less likely outcome given that B1059 had successfully completed four launches and landings at that point. Ultimately, while nothing is known for sure, payload-side issues with the NROL-108 satellite(s) are the most likely cause of most of the eight-week delay that followed. Now, confirmed by the NRO on December 14th, SpaceX is scheduled to launch its second mission for the spy agency no earlier than (NET) 9 am to 12 pm EST (14:00-17:00 UTC) on Thursday, December 17th.
For SpaceX, this will be the third time in a single month that a customer has effectively leapfrogged several Falcon 9 booster reuse milestones, once again exhibiting an extreme amount of confidence in the company’s expertise with flight-proven rockets. On December 6th, Falcon 9 booster B1058 lifted off for the fourth time in support of SpaceX’s CRS-21 space station resupply mission for NASA, marking the space agency’s first launch on a twice- or thrice-flown booster.
On December 13th, carrying a large communications satellite for Sirius XM, another Falcon 9 booster lifted off for the seventh time, becoming the first private customer to launch on a five-flight or six-flight SpaceX rocket.
As few as four days after SXM-7, SpaceX is now scheduled to launch the mysterious NROL-108 mission. It will be the first time the NRO has launched a payload on a flight-proven commercial rocket of any kind, as well as its first launch on a two-flight, three-flight, or four-flight booster – by far the biggest numerical leap a SpaceX customer has ever taken. NRO’s first and only SpaceX launch – technically contracted by spacecraft provider Bell Aerospace, not NRO itself – was completed in May 2017.
While less significant, NROL-108 will also be SpaceX’s first US government launch on a four-flight Falcon 9 booster, yet another indication that even its most conservative customers have fully bought into the value and technical viability of reusable rockets.
After launch, Falcon 9 B1059 will flip around and head back towards the Florida coast for a landing at one of SpaceX’s two East Coast Landing Zones. Deploying a minute or so after booster separation, Falcon 9’s two payload fairing halves are expected to splash down some 330 km (~205 mi) downrange, where SpaceX recovery ships GO Search and GO Ms Tree will attempt recovery.

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.
