Russia quietly shelves development of sole SpaceX Falcon 9-competitive rocket
Russian space agency Roscosmos has indefinitely suspended development of the Proton Medium rocket, once expected to help the country compete with the meteoric rise of SpaceX and the growing field of interested entrants in the commercial launch industry.
As Russia makes a greater push toward Angara rockets, it is sidelining development of Proton Medium, a vehicle ILS hoped would compete head on with SpaceX's Falcon 9. https://t.co/BD6AOusalK

The (probable) death of a rocket
In an extraordinary feat of double-speak, freshly appointed Roscosmos director general Dmitry Rogozin – likely a primary source of Proton Medium’s paused development – explained that Russia’s national rocket program would likely experience the “financial collapse of [its] enterprise” if it chose to build “both old and new heavy-duty rockets” simultaneously. Rogozin clearly implied that Angara – a Russian rocket that has flown once (successfully) in 2014 and has a commercial demand about as close to near-zero as possible – was the “new” rocket that Roscosmos ought to solely pursue.
Indeed, upon analyzing the public specifications of Angara A5 and Proton Medium, the two rockets have near-identical theoretical performance characteristics, with higher geostationary transfer orbit payload capabilities (5-6 tons) roughly comparable to Falcon 9 in the SpaceX rocket’s drone ship recovery configuration. As a result, it certainly would make very little sense for Russia to fund and build two rockets with nearly indistinguishable utility – Rogozin certainly is correct in that regard.
-->However, the space agency director is dumbfoundingly off-base in his suggestion that Angara – not Proton Medium or other proposed alternatives – is the way forward to a financially sustainable Roscosmos. As he himself notes, “eternal state support [of launch vehicles] is impossible and inefficient,” seemingly indicating that he believes any viable state-funded rocket must eventually become a serious commercial competitor, a necessity for a launch vehicle if it’s to sustain itself beyond subsidies (i.e. guaranteed government launch contracts).

The “old” versus the “new”
The Proton family of rockets – past and present – may not have the most reliable track record or a consistent launch cadence, but nearly any rocket on Earth can lay claim to a more storied launch career when placed next to Angara. Despite the fact that the Russian government itself has funded the development and production of Angara rockets, just a single orbital mission has been launched, and only with a mass simulator (dead weight) as its payload. Since that one-off 2014 launch debut, not even the Russian government itself has chosen to fly state satellites on Angara, instead siding with other successful vehicles in the country’s fleet, including Proton Breeze M and Soyuz-2.
This is almost without a doubt because Angara A5 is the most expensive rocket Russia currently operates, reportedly 30-40% more expensive than Proton M, estimated in 2017 by the US Government Accountability Office to cost roughly $65 million per launch. At roughly a third more than that, an Angara A5 launch presumably costs ~$90 million in a best-case scenario, given that the manufacturing apparatus required to construct the rocket has been maintained on a manifest of exactly zero launches since 2014. In fact, the vehicle was estimated by Russia itself to cost roughly $95 to $105 million per launch back in 2015.

-->In an interview with SpaceNews in late 2017, the president of the commercial wing of Russia’s space launch program (known as ILS) frankly stated that “[ILS] needs to target something between $65 [million] and $55 million as the price point [for Proton Medium], and the Angara 5 vehicle will not be able to do that.” In the same interview, the ILS president even went so far as to imply that “Proton Medium was being designed as a purely commercial competitor to SpaceX’s Falcon 9.”
While there is a very slim chance that Proton Medium’s development will be revived after Roscosmos’ internal review, it’s far safer to presume that the vehicle is dead, thus killing Russia’s only tenuous hope of fielding a rocket capable of competing with the likes of SpaceX and Blue Origin. While Roscosmos’ goal is to make Angara (an entirely expendable rocket, might I add) more affordable, it anticipates that the rocket would become cost-competitive with Proton no earlier than 2025.

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.
