SpaceX private astronaut launch debut to reuse Crew-1 Dragon spacecraft
A former NASA astronaut now employed by Axiom Space says that SpaceX’s private astronaut launch debut will reuse the same Crew Dragon spacecraft currently supporting NASA’s Crew-1 mission in orbit.
Currently just a few weeks into a planned six-month stint in orbit, potentially marking the longest uninterrupted flight of an American spacecraft ever, Crew Dragon capsule C207 and an expendable trunk section arrived at the International Space Station (ISS) on November 16th. Known as Crew-1, the mission represents SpaceX and NASA’s commercial operational astronaut launch debut, carrying four astronauts to the ISS.
Crucially, the mission has been an almost flawless success so far and Falcon 9 has now completed four Crew Dragon launches without issue. On the Dragon side of things, the Crew-1 spacecraft performed a bit less perfectly than those tasked with flying Demo-1 and Demo-2, but SpaceX handled the minor issues that arose with the professionalism and composure of a team far more familiar with human spaceflight.
Early success aside, there is still some definite uncertainty ahead of Crew Dragon. While several Russian spacecraft have decades of experience spending at least several months at a time in orbit, a crewed US spacecraft has never spent more than 84 days in orbit. SpaceX itself actually beat out NASA to secure the second-place record with Crew Dragon’s 63-day Demo-2 astronaut launch debut, completed with a successful reentry and splashdown on August 2nd.
However, Crew-1 is expected to more than double that previous US record and almost triple SpaceX’s own second-place record, spending roughly 180 days (six months, give or take) in orbit. Barring an unprecedented space station or spacecraft emergency, Crew Dragon C207 will undock from ISS, reenter Earth’s atmosphere, and splashdown in the Gulf of Mexico or the Atlantic Ocean sometime in May 2021. Of course, as the first recoverable US spacecraft to spend anywhere close to that long in orbit, the Crew-1 Crew Dragon will be closely monitored to ensure the safety and reliability of its intricate reentry and recovery systems after some six months exposed to the extremes of space.
Still, success is by far the likeliest outcome. When Crew Dragon C207 splashes down, its four astronaut passengers will be carefully extricated and the inspection and refurbishment process will begin almost immediately thereafter. Crew-1 will technically be the second Crew Dragon spacecraft to be refurbished after an orbital spaceflight, following Demo-2 capsule C206’s inaugural Dragon 2 reuse perhaps just a month or two prior.
The Demo-2 Crew Dragon capsule is currently scheduled to fly a second time as early as March 31st, 2021 on SpaceX’s Crew-2 mission, ferrying another four astronauts to the ISS. If successful, Crew-2 will represent the first commercial astronaut launch ever to reuse both an orbital-class rocket booster and an orbital spacecraft, and the NASA-overseen process of refurbishment and re-flight will thus pave the way for future flight-proven astronaut launches. That includes private company Axiom Space’s first private AX-1 astronaut launch, which is currently scheduled to launch as early as Q4 2021.
AX-1 will be captained by former NASA astronaut Mike Lopez-Algeria and carry three other private astronauts, including Israeli multimillionaire Eytan Stibbe. SpaceX will thus be tasked with launching Israel’s second astronaut ever after Ilan Ramon was killed when a heat shield design flaw caused NASA Space Shuttle Columbia to break up during reentry in 2003.

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.
