SpaceX’s first Falcon Heavy launch in two years is finally coming together
For the first time in more than two years, SpaceX’s next Falcon Heavy launch and dual-booster landing appears to be right around the corner – and it comes with a catch.
In February 2018, after years of anticipation, SpaceX successfully launched its triple-booster Falcon Heavy rocket for the first time in a spectacular show of force. Though the ‘center core’ booster got a little melty on its extremely high-speed reentry and was lost before it could attempt to land, the rocket’s twin side boosters performed an iconic near-simultaneous landing just a handful of miles away from where they lifted off.
Then Falcon Heavy took a good, long break. Ultimately, it would turn out that the debut vehicle was effectively a one-off and over the course of 14 months, SpaceX fairly quickly designed, built, and qualified an entirely new Falcon Heavy rocket based on Falcon 9’s new and improved Block 5 variant. In April 2019, after a few minor delays, that Falcon Heavy Block 5 rocket completed its own launch debut and first mission for a paying customer. This time around, all three boosters – two by land and one by sea – survived reentry and performed flawless landings on a drone ship and two Landing Zones.
A mere two months later, both of Falcon Heavy Block 5’s first two recovered side boosters flew again in support of the US Air Force’s STP-2 mission – a combined demonstration flight and rideshare mostly designed to push the rocket to its limits and help the military qualify it for high-value payloads. Once more, those side boosters successfully returned for a simultaneous landing at SpaceX’s Landing Zones but the mission’s Block 5 center core’s reentry was – as SpaceX itself partially expected – too hot, burning essential components and resulting in a hard ‘landing’ in the Atlantic Ocean. Otherwise, the mission was a spectacular success and gave the US military practically all the data it needed to qualify the world’s largest operational rocket to launch its payloads.
Shockingly, however, that June 2019 launch would end up being Falcon Heavy’s third and latest. In the almost 26 months since, the rocket hasn’t flown once. Originally scheduled to launch a fourth time as early as Q4 2020, the COVID-19 pandemic ultimately delayed the rocket’s next two launches (or gave the satellite manufacturer(s) perfect scapegoats for technical delays) into 2021.
-->Known as USSF-44 and USSF-52 (formerly AFSPC-44/52), both missions are scheduled to launch ethereal US military spy and/or communications satellites. USSF-44 is arguably the most important, as it will mark SpaceX’s first direct launch to geostationary orbit (GEO) for any customer – let alone one as exacting as the US military. USSF-52 is a much simpler and more traditional launch to an elliptical geostationary transfer orbit (GTO).
About a year ago, for unknown reasons, the two missions swapped positions, with USSF-44 taking the lead. Expected to launch in June 2021 as of early this year, SpaceflightNow first reported that USSF-44 had slipped further still to October – and USSF-52 into 2022 – this May. Since then, that’s where the mission’s schedule has tentatively lain.
Finally, on August 12th, SpaceX filed an FCC application for rocket communication permissions. While otherwise ordinary, this particular request stated that it was for Falcon Heavy recovery operations and, more specifically, for the simultaneous recovery of two Falcon Heavy boosters at sea. Out of an abundance of caution and conservatism and combined with the generally challenging nature of direct-to-GEO launches, Falcon Heavy’s first such mission for the US military will require SpaceX to expend the rocket’s center booster and recover both side boosters at sea with two separate drone ships.
Falcon Heavy’s USSF-52 GTO launch isn’t as demanding and its mission profile is expected to allow SpaceX to recover all three boosters. As such, an FCC filing for a dual-drone-ship Falcon Heavy side booster recoveries practically guarantees that it’s for USSF-44. Per the application, SpaceX expects the mission to occur no earlier than September 25th. Almost simultaneously, launch photographer Ben Cooper also updated a long-running list of upcoming East Coast launches, confirming that Falcon Heavy’s fourth launch (USSF-44) remains on track for October 2021.
Ultimately, while delays are possible and likely probable, there now appears to be a strong chance that Falcon Heavy will launch for the first time in 28 months before the end of 2021.

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.
