SpaceX to livestream private BFR Moon mission “in high-def VR” with Starlink satellites
Following a detailed update to SpaceX’s BFR plans and the first privately contracted mission to the Moon, CEO Elon Musk has tweeted that the company intends to stream the entire six-day journey in “high def VR”, a plan that would demand unprecedented communications capabilities between the Moon and the Earth.
Musk further confirmed that “Starlink should be active by [2023]”, suggesting – at a minimum – that the SpaceX-built and SpaceX-launched internet satellite constellation will have reached what is known as ‘initial operating capability’, pegged for Starlink at roughly 800 satellites launched.
Moon mission will be livestreamed in high def VR, so it’ll feel like you’re there in real-time minus a few seconds for speed of light

No small task
To give some rough context for what Musk wants, streaming in high-enough quality for a good virtual reality (VR) experience on a deep space voyage around the Moon will demand a sea of bandwidth that’s difficult to find even on the surface of Earth, let alone in space. A 2017 estimate pegged the bandwidth requirements for 4K VR streaming around 300 megabits per second (Mbps), while a solution more fitting for five years of iterative improvement between now and 2023 might demand almost a magnitude greater bandwidth (~3000+ Mbps).
-->For context, the average American internet connection hovers around 15-20 Mbps while the average 4K YouTube video takes about 25 Mbps to stream, meaning that BFR’s communications link between the ~390,000 km (240,000 mi) Earth-Moon gap would need to be anywhere from 10 to more than 100 times faster than typical Earthly connectivity. While NASA has already completed a successful tech demonstration of laser communications from the Moon to the Earth, maxing out at a rather impressive ~620 Mbps in 2013, that one-off test concluded years ago, and there simply is no infrastructure available to achieve the sort of capabilities SpaceX will need to stream a lunar voyage in VR.
Starlink to the rescue
The only possible way SpaceX could accomplish this sort of technical feat is by having their own high-bandwidth satellite constellation at least partially operational, needs that mesh reasonably well SpaceX’s public planning schedule for their Starlink constellation. Speaking in late-2017, SpaceX VP of Satellite Government Affairs Patricia Cooper laid out a timeline that would see ~800 satellites launches sometime in the early 2020s, followed later by the remaining ~3600 spacecraft in the Phase 1 constellation. Those launches would take place between 2019 and 2024.
Since then, Musk has indirectly hinted that Starlink’s schedule has slipped or stretched 6-12 months, unsurprising for such a massive technical task at hand. This still leaves a fair amount of time for some sort of initial operational capability to be realized, even if it is little more than the skeleton necessary for Musk’s high-def VR-streaming ambitions. Although the tweet response that triggered it was deleted, Musk confirmed in the comments of his original tweet that Starlink would be the relay network of choice – having an Earth network already installed would certainly minimize the need for global ground stations to receive a BFR spaceship’s continuous lunar downlink.
Yeah, Starlink should be active by then
— Elon Musk (@elonmusk) September 18, 2018
Evidenced by previous comments from Musk and NASA execs expressing interest in developing a commercial communications relay between Earth and Mars, the thought is at least there that the Starlink satellite bus may sooner or later be called upon to serve as deep space communications relays throughout the solar system, beginning with the Moon and Mars.

It’s possible that those distinct space environments would necessitate changes to the spacecraft’s hardware and software, but the fundamental goal of mass-producing Starlink satellites at an unprecedented scale and cost means that a few off-the-shelf satellites could plausibly be placed in relay positions under the assumption that they will die faster than those in Earth orbit. At just a few hundred kilograms apiece, Falcon 9 would have no problems launching a handful to the Moon or elsewhere, and they could potentially be included as copassengers on BFR launches, acting as a sort of a la carte communications relay for the spaceship.
Time will tell, but SpaceX fans certainly have an incredible amount of things to look forward too from the last 48 hours alone, regardless of whether the #dearMoon BFR mission’s 2023 launch target slips (spoiler: it probably will).

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.
