SpaceX’s historic private astronaut launch debut gets its own Netflix documentary
Netflix has announced plans for a documentary that will dive deep into SpaceX’s historic Inspiration4 private astronaut launch.
Headed by billionaire and Shift4 CEO and founder Jared Isaacman, Inspiration4 was first announced in February 2021 as SpaceX’s first private Crew Dragon mission. More importantly, the mission – if successful – will make history as the first fully private astronaut launch in the history of spaceflight when it sends four private citizens into orbit later this year.
Set to launch as early as September 15th, perhaps just two months after Virgin Galactic and Blue Origin’s (in)famous dueling crewed suborbital debuts, SpaceX will hopefully show the world what space tourism really is. Unlike Blue and Virgin, which have been working for a decade to develop suborbital tourist vehicles that will never stray more than ~20% of the way to useful spaceflight, SpaceX’s Crew Dragon is an orbital spacecraft and will spend a minimum of several days orbiting the Earth with its Inspiration4 astronauts.
In the process of preparing for their roles on the world’s first privately-crewed orbital spacecraft, all four Inspiration4 crewmembers have been training for months to ensure that they’re reasonably knowledgeable and comfortable with true spaceflight. That includes operating and living in Crew Dragon – a nominally autonomous spacecraft that nevertheless could require manual intervention in the event of an emergency.
Though Virgin Galactic or Blue Origin tourists are undoubtedly faced with significant danger on their suborbital jaunts, as evidenced by a fatal SpaceShipTwo test flight in 2014, they’re generally just a few minutes away from help throughout. Virgin’s SpaceShipTwo vehicle is carried to its launch point on an aircraft and is technically a glider itself, while Blue Origin’s New Shepard capsule can abort at any point during the rocket’s relatively relaxed trip to ~100 km (~62 mi) and Mach 4 (~3000 mph). Save for the pilots flying SpaceShipTwo, none of the passengers are in any position to influence the outcome of a flight in the event that something goes wrong.
-->In orbit, however, the sheer altitude and velocity at which astronauts and their spacecraft are traveling means that “help” is either hours away, limited to a remote “mission control,” or – in worst-case scenarios – contained exclusively inside the vehicle itself. Put simply, an orbital spacecraft with minimally trained tourists as “crew” will always raise the risk of a scenario where something goes wrong and something could have been done on-orbit to avert catastrophe but those aboard have too little training to save themselves.
As such, even though Crew Dragon is designed to fly with zero human intervention, the spacecraft has only completed three crewed launches and two crewed reentries – not exactly the kind of sample size one might gamble their life on. Of course, Falcon 9 is an extraordinarily reliable rocket and Crew Dragon has proven itself well over its two-year career. The spacecraft also has a built-in abort system that can feasibly whisk its crew to safety at any point from the launch pad to orbit.
But given the low price of a few months of hard work and inconvenience for a shot at saving one’s own life in an admittedly unlikely emergency, it’s likely that private astronauts (orbital space tourists) will go through significant training for years to come.

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 upgrade follows earlier phases of Tesla’s self-funded shuttle 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.
