SpaceX, NASA schedule back-to-back astronaut recovery and launch after delays
Poor winter weather on Florida’s East Coast and across the Atlantic Ocean has forced NASA and SpaceX to flip the nominal sequence of events for the imminent back-to-back launch and recovery of two Crew Dragons.
Contrary to preference, SpaceX and NASA’s four Crew-2 astronauts are now scheduled to undock from the International Space Station (ISS) and return to Earth before their replacements (Crew-3) launch to the station. As a result, there will be no on-orbit handoff, meaning that only one NASA astronaut – Mark Vande Hei – will be left alongside cosmonauts Anton Shkaplerov and Pyotr Dubrov to crew and operate the US segment of the ISS until Crew-3’s arrival.
After several delays from an initial October 30th target, Crew-3 astronauts Raja Chari, Thomas Marshburn, Matthias Maurer, and Kayla Barron are scheduled to ride Falcon 9 and Crew Dragon to orbit no earlier than (NET) 9:03pm EST, Wednesday, November 10th (02:03 UTC 13 Nov) – two days after Crew-2 is expected to splash down.
Save for a one-day delay from October 30th to October 31st needed to give SpaceX and NASA time to qualify a fixed plumbing leak for crewed spaceflight, all subsequent delays into November have been caused by poor weather – a rather common late fall and winter occurrence in the Atlantic Ocean and southern US. The weather isn’t entirely to blame, though. Crew Dragon, SpaceX, and NASA are also partly responsible due to the extremely strict and narrow range of weather conditions the spacecraft has been certified to operate in.
Worse, a large portion of Dragon’s weather constraints are for hypothetical abort scenarios rather than the nominal launch – not “is it safe to launch?” but “is it safe to launch if something fails catastrophically and Dragon aborts and has to splash down anywhere in a several-dozen-mile corridor stretching the entire length of the Atlantic?” In the case of Crew-3’s launch, the main condition making that vast abort zone a no-go for launch is surface winds.
While aborting an expensive, time-sensitive rocket launch due to ground winds might bring to mind some kind of storm with vast swells and torrential rain, the reality is that NASA has only rated Crew Dragon to splash down when surface winds are less than 8-11 mph (13-18 km/h). In other words, the conditions causing 10+ days of delays and leading NASA to leave a skeleton crew at the space station’s US segment amounts to a firm breeze. There are likely many reasons (most hopefully good) for that highly conservative limit but ultimately, it means that NASA’s Crew Dragon missions will almost always be at risk of weather delays both going up and coming down.

As if to emphasize that fact, winds in the Gulf of Mexico, on the opposite side of Florida, also caused NASA to delay SpaceX’s Crew-2 departure and splashdown from November 6th/7th to November 8th, raising the risk of more Crew-3 delays or another complex schedule conflict if conditions force another change. A minor issue with Dragon’s toilet discovered during Inspiration4 and fixed on Crew-3’s ride to space will preclude its use during Crew-2’s 11-hour trip home, but that change should be barely noticeable to professional astronauts that are required to wear diapers as a precaution regardless. Otherwise, throughout the delays, Falcon 9 B1067, Crew-3 Dragon C210, and Crew-2 Dragon C206 have all thankfully remained healthy and ready to go.
Crew-2 is scheduled to undock from the ISS around 2pm EST (17:00 UTC) on November 8th and could splash down as early as 10:33 pm (03:33 UTC) – less than nine hours later.

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.
