SpaceX Falcon 9 wins Korean launch contract as 2019 mystery missions persist
SpaceX has silently announced that Falcon 9 won a contract for a South Korean military communications satellite, currently scheduled to launch from the company’s Cape Canaveral Air Force Station (CCAFS) LC-40 pad no earlier than November 2019.
Subcontracted from Lockheed Martin to Airbus Defense and Space in 2016, the satellite – known as Anasis II (formerly KMilSatCom 1) – is based on a common bus built by Airbus and could weigh anywhere from 3500 to 6000 kilograms (7500-13,200 lb). Falcon 9 will be tasked with launching Anasis II to geostationary transfer orbit (GTO), after which the satellite will use its own onboard propulsion to circularize the orbit and begin operations. Although the Korean contract brings SpaceX one step closer to its goal of 18-21 launches (excluding Starlink) in 2019, it also raises the question: what mystery missions are missing from public launch manifests?
Manifest Mystery
As previously discussed in both Teslarati articles and newsletters, comments from SpaceX executives in February and May 2019 reiterate the company’s expectation of 18-21 launches in 2019, excluding Starlink. Hofeller’s “more than 21 launches” admittedly came more than two months before a catastrophic Crew Dragon failure threw the spacecraft’s launch manifest into limbo.
Three months later, SpaceX President and COO Gwynne Shotwell reiterated the idea that SpaceX could beat its 2018 launch record (21 launches) or at least get close. Curiously, she specifically noted that SpaceX’s purported 18-21 launch manifest excluded Starlink missions, of which SpaceX has already launched one. In short, SpaceX has completed 7 launches in 2019 (6 if Starlink v0.9 is excluded). The company’s public manifest – unofficially cobbled together by fans – shows 9 more launches scheduled for a total of 15 non-Starlink launches in 2019.
To meet Shotwell’s expected 18-21 non-Starlink launches, anywhere from 3 to 6 missions are apparently missing from publicly-managed launch manifests. It’s unclear if SpaceX actually has enough launch-ready customers to achieve those ambitious targets. Additionally, SpaceX is currently on track to complete 8 launches total (1 Starlink) in the first half of 2019. In 2017 and 2018 (two years without interruption), SpaceX consistently launched an equivalent number (or more) missions in the first half of the year when compared to the second half, and both years have maxed out at 9 launches in H2.
SpaceX will have to beat that H2 record to reach 18 launches in 2019 even if Starlink missions are counted. Meanwhile, SpaceX says that as many as 1-5 additional Starlink launches are scheduled for 2019, bringing the total number of missions as high as 20-27 in differing best-case scenarios. Practically speaking, between SpaceX’s Pad 39A and LC-40 launch facilities, the company could easily maintain a biweekly or even weekly cadence (13-26 launches in H2 2019). The real constraint, however, is hardware availability – i.e. whether SpaceX has the rocket pieces and flight-ready satellite(s) it needs to launch a given mission.
Can SpaceX do it?
This is an extremely hard question to answer, as all details that really matter are of the organizational, company-secrets sort that SpaceX just doesn’t publicize. From a technical and practical perspective, the answer is a reasonable confident “yes.” If Falcon Heavy Flight 3 (STP-2) is completed successfully, SpaceX will have an impressive fleet of at least 8 flight-proven Falcon 9-class boosters. Even assuming that no progress is made beyond the current Block 5 turnaround average of ~110 days (~3.5 months), SpaceX’s current fleet should be able to immediately support four launches and an additional 8-12 before the end of 2019.
The primary limit, then, would be SpaceX’s ability to produce Falcon 9 upper stages and fairings, as well as the stamina and quality of the company’s managers and employees. Even then, the question of SpaceX’s 3-6 mystery launches will remain unanswered until either the customer or launch provider choose to open up. For now, we wait…

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->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-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

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.
