SpaceX’s next Falcon Heavy launch slips into 2021
SpaceX’s next Falcon Heavy launch – set to be the rocket’s fourth overall – has slipped several months into 2021 according to the vice commander of the US Air Force Space and Missile Systems Center (USAF SMC).
Known as AFSPC-44 (now USSF-44), the nature of Falcon Heavy’s next payload remains a mystery. Headed to geostationary orbit, the satellite will likely be involved in military satellite communications, possibly including espionage (also known as signals intelligence or SIGINT). Technically, the USSF-44 mission includes two separate satellites and at least two additional rideshare payloads and will weigh roughly 3.7 metric tons (~8200 lb) at launch.
When the contract was announced, Falcon Heavy was expected to launch USSF-44 no earlier than (NET) Q4 2020. By April 2020, that target was closer to late November or December. Now, four months after that report, Brigadier General Jason Cothern says that SpaceX’s next Falcon Heavy launch is scheduled NET February 28th, 2021.
The delay doesn’t come as much of a surprise. Based on public observation of SpaceX’s Falcon booster production and testing, requiring thousands of miles of extremely conspicuous highway transport, it was already clear that the mission was unlikely to launch this year. Of the six first stages spotted in transport over the last nine months, all were clearly Falcon 9 boosters and lacked any of the telltale parts that distinguish Falcon Heavy side and center boosters.

The most recent ‘core spottings’ – a new Falcon 9 booster headed West after acceptance testing and another preparing for acceptance testing in Texas late last month – all but confirmed that USSF-44 was significantly delayed. Since mid-2019, SpaceX has intentionally slowed down Falcon booster production to focus on the higher-volume production of expendable hardware (fairings and second stages). While the company could technically complete boosters every two weeks if its feet were put to the coals and has generally averaged 10 per year, that figure has dropped closer to 6-8 boosters per year over the last ~18 months.
Coupled with a report that all three of the USSF-44 Falcon Heavy rocket’s boosters would be brand new, the lack of sightings in the wild implied that has yet to ship even one of those complex rockets to McGregor, Texas for acceptance testing. Based on preparations for Falcon Heavy’s April 2019 Block 5 launch debut, the process of testing three new Falcon boosters singlehandedly takes at least three months. Additionally, all three of the Arabsat 6A mission’s new Falcon Heavy boosters arrived in Florida a full two months before launch.

In other words, given that a brand new Falcon 9 booster rolled out of SpaceX’s Hawthorne, CA factory on August 24th and that said factory isn’t really set up for concurrent booster completion, it would take unprecedented feats of manufacturing and testing for Falcon Heavy Flight 4 to be ready to launch less than four months from now (around the turn of the New Year).
In fact, even under the assumption that the next three boosters on SpaceX’s factory assembly line are all for Falcon Heavy Flight 4, the new February 2021 launch date is going to be a tight deadline. There is no evidence that SpaceX production delays are to blame for the USSF-44 launch delay and the coronavirus-related disruption of satellite production is equally – if not more – likely. Either way, SpaceX’s fourth Falcon Heavy launch will have to wait a few extra months. Barring a surprise mission over the next six months, Falcon Heavy Flight 4 will also be SpaceX’s first operational launch directly to geostationary orbit (GEO).

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.
