SpaceX to launch Falcon Heavy rocket 3 times in 6 months after latest payload delay
For at least the second time in 2021, unspecified issues with a US military payload have delayed SpaceX’s next Falcon Heavy launch, this time pushing the mission into next year.
Known as USSF-44 (formerly AFSPC-44), the US Air Force (now Space Force) contracted a SpaceX Falcon Heavy rocket in February 2019 to launch the classified payload for roughly $150M in fiscal year 2021 (no earlier than Q4 2020). Gradually, USSF-44 slipped without explanation to Q2 2021, at which point SpaceX had fully qualified and delivered all three new Falcon Heavy boosters and an expendable upper stage for the mission. After two more slips to July and October 2021, a US military official finally offered the first hint of an explanation for what now amounted to a full year of delays, explaining that USSF-44 had been pushed into Q4 “to accommodate payload readiness.”
Translated from US military doublespeak and euphemism, the manufacturer (likely Lockheed Martin, Northrop Grumman, or Boeing) building USSF-44’s classified payload(s) ran into or create issues that caused at least 3-6 months of delays. Now, per official comments obtained from a Space Force spokesperson by Spaceflight Now, USSF-44 has again been delayed several months “to accommodate payload readiness,” pushing Falcon Heavy’s fourth launch ever from October 2021 to no earlier than (NET) Q1 2022.
USSF-44’s latest delay means that SpaceX is now likely to go a full 30 months between Falcon Heavy flights after completing the rocket’s third and most recent launch in June 2019. The slip to “early 2022” also leaves the company with an extremely ambitious launch manifest in the first half of 2022. Barring one or several significant delays, which now seems like the most plausible outcome, SpaceX has four major Falcon Heavy missions – USSF-44, USSF-52, ViaSat-3, and NASA’s Psyche probe – scheduled to launch set to launch by August, with three of the four scheduled in H1 2022. A fifth mission – USSF-67 – is scheduled to launch in Q4 2022 and likely on another Falcon Heavy rocket, though the US military has yet to specify the Falcon variant.
Further, requiring the use of the same Kennedy Space Center (KSC) LC-39A pad, SpaceX also has at least six Crew and Cargo Dragon launches scheduled in February (Ax-1), April (Crew-4), May (CRS-25), Q3 (Ax-2), September (CRS-26), and October 2022 (Crew-5). In other words, in Dragon and Falcon Heavy missions alone, SpaceX already has 10-11 launches scheduled in 2022 – all of which require the use of Pad 39A. If SpaceX manages to pull that off on top of a myriad of other commercial and Starlink launches scheduled next year, it will be a feat to remember.
-->Barring additional delays, USSF-44 will be SpaceX’s first direct launch to geostationary orbit (GEO), requiring the Falcon upper stage to survive a multi-hour coast through and inside two radiation belts before reigniting for a circularization burn some 35,800 km (22,300 mi) above Earth’s surface. However, a rideshare payload transferred to SpaceX’s ViaSat-3 communications satellite launch recently revealed that SpaceX also intends to send those payloads directly to GEO in Q2 2022, meaning that another few months could force the company to leapfrog USSF-44.
For now, fans of the most powerful operational rocket in the world will have to wait at least another three months for its next launch.

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.
