SpaceX Crew Dragon aces third autonomous space station docking
Update: A SpaceX Crew Dragon has successfully performed an autonomous rendezvous and docking with the International Space Station (ISS) for the third time in a row and the first time with four astronauts aboard.
Near-flawless space station arrival now behind it, Crew Dragon has effectively kicked off what could be the longest continuous spaceflight of a crewed US spacecraft in the history of American space exploration. Barring surprises, Crew Dragon capsule C207 (deemed “Resilience” by its first crew) and its expendable trunk section will spend roughly 180 days in orbit, crushing the previous US record of 84 days set by an Apollo Command and Service Module spacecraft in 1973.
Crew Dragon’s first successful operational space station arrival also marks the beginning of a small but significant new era for the ISS, enabling a crew of seven astronauts – up from six – to continuously live and work aboard the 20-year-old orbital outpost. Thanks to the station’s well-quantified needs for regular maintenance and operational expertise, that new seventh crew member will ultimately be able to dedicate almost every working moment to doing science in orbit.
Meanwhile, ISS NASA astronaut Kate Rubins hinted to SpaceX and NASA ground control that a range of photos she took of Crew Dragon’s third ISS arrival were likely to be spectacular. A ground controller took no time to respond with the quip that “[Crew Dragon] is known objectively to be a very good-looking vehicle.” Stay tuned for another update when those approach photos go live.
Approximately two hours after Crew Dragon’s third successful docking, Rubins successfully completed an array of tasks and opened the spacecraft’s hatch, allowing NASA astronauts Mike Hopkins, Shannon Walker, Victor Glover, and JAXA astronaut Soichi Noguchi to officially depart Dragon and join the International Space Station’s existing crew of three.
A SpaceX Crew Dragon is set to rendezvous and dock with the International Space Station for the third time later tonight and its four-astronaut crew took some time during their 27-hour flight to give live viewers a tour of the brand new spacecraft.
Emphasizing just how much space Crew Dragon offers its astronaut passengers once in orbit, the tour also included a minor tradition for NASA astronaut Victor Glover’s first orbital spaceflight. Astronauts Soichi Noguchi, Mike Hopkins, and Shannon Walker – all spaceflight veterans – commemorated Glover’s milestone with the gift of a small, golden pin, continuing a decades-old tradition.
-->If Crew Dragon remains in good health, the four astronauts will officially kick off the first ISS docking attempt with a 90-second thruster burn shortly after 9 pm EST (02:00 UTC).
Quite similar to Crew Dragon’s flawless Demo-2 astronaut launch debut, the Crew-1 spacecraft is scheduled to arrive at what is known as the ISS keep-out sphere around half an hour after its final major course-change thruster burn. Dragon will pause approximately 400m (~1300 ft) from the space station and wait for ground and station teams to give it the go-ahead to continue to another stopped point 20m (65 ft) out.
Altogether, the Crew-1 Dragon docking process will take about 55 minutes after the spacecraft enters the keep-out sphere and will culminate with a ‘soft’ capture around 11pm EST (04:00 UTC) and a ‘hard’ capture – signified by the docking port firmly bolting Dragon to the ISS – a bit less than 15 minutes later.
Orbital sunset is expected roughly 10 minutes before docking, meaning that Crew Dragon’s Crew-1 docking should be sunlit from a distance of ~1000 to 20 meters (3300 to 65 ft) from the ISS. Tune in below to watch the historic docking live.

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.
