SpaceX seeks approval for Starlink internet tests on high-performance govt. planes
According to updated regulatory documents and recent Aviation Week interviews with the US Air Force Research Laboratory, it can be all but guaranteed that the USAF has begun working with SpaceX to test the feasibility of using the company’s planned Starlink satellite internet constellation for military communications purposes.
In early August, SpaceX updated regulatory documents required by the Federal Communications Commission (FCC) for the company to be permitted to experimental test its two prototype Starlink internet satellites, named Tintin A and B. Launched roughly six months ago as a copassenger on one of SpaceX’s own Falcon 9 rockets, the satellite duo has been quietly performing a broad range of tests on orbit, particularly focused on general satellite operations, orbital maneuvering with SpaceX’s own custom-built electric propulsion, and – most importantly – the experimental satellites’ cutting-edge communications capabilities.

Per a public summary of the application update, SpaceX is awaiting FCC permission to begin a new series of tests of its prototype satellite internet network, this time highlighting an intriguing interest in applying Starlink connectivity to moving aircraft in order to provide them an exceptionally flexible and powerful suite of communications capabilities.
-->“SpaceX seeks to modify its experimental authorization to allow testing of two different antennas, both of which will operate on the ground and one of which will also operate from a moving aircraft.”
In those same documents, the company states that it is “working with a manufacturer of conformal antennas for tactical aircraft” to design and build “a custom installation kit consisting of mechanical plates for the low-profile antennas and fairings reducing wind drag”, seemingly indicating that SpaceX itself intends to supply the phased array antennae itself. Normally, this sort of testing would be fairly mundane and expected for any global satellite network, as one of the largest markets for satellite internet connectivity happens to be commercial aviation, particularly airlines and passenger entertainment.

However, the plot thickens beyond that extent thanks to a few select phrases. Most tellingly, the company writes that it “will perform a series of tests with the integrated airborne prototype terminal … varying motion for representative roll and pitch rates of a high-performance aircraft“, later also describing the program the update as a request for permission for “additional test activities undertaken with the federal government.”
It just so happens that the US Air Force’s Research Laboratory (AFRL) spoke with Aviation Week earlier this year (just weeks after SpaceX’s first prototype satellites had launched, in fact) about a nascent program exploring the potential utility of a spate of commercial Low Earth Orbit satellite internet constellations proposed for launch in recent years.
“To explore the art of the possible, AFRL is planning to contract with at least one commercial internet provider for a set of antennas that can be mounted onto Air Force test aircraft, Beal says. The team will then fly the aircraft … directly under the associated satellites and establish a communications path.” – Lara Seligman/AviationWeek

As of publishing then (March 2018) and now, SpaceX is the only company in the world to have launched a pair of functional demonstration satellites as a part of its proposed megaconstellation, meaning that it’s the only company that has a (technically) operational network with which they can test inter-satellite connectivity, connection hand-offs between different satellites, and multi-satellite operations.
While it’s currently unclear how that series of tests transpired and if they were or are officially connected to the AFRL’s own program, the briefest thought of the USAF (and thus the Department of Defence) as a prospective anchor customer for SpaceX’s Starlink constellation is extraordinarily exciting, especially given the apparent difficulties and costs associated with actually deploying even the first wave (~900 satellites) of such a massive constellation (~4500 satellites total).

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.
