SpaceX’s Crew Dragon just became America’s longest-lived astronaut spaceship
SpaceX’s Crew Dragon has officially become the longest-lived American astronaut spacecraft ever built, beating an 84-day record set by the Apollo-era Skylab-4 mission almost half a century ago.
Crew Dragon was able to beat that record so quickly because NASA ultimately chose to cannibalize its existing Saturn rocket and Apollo CSM spacecraft expertise, production capabilities, and budget to go all-in on the Space Shuttle program. Meant to be quickly and cheaply reusable, a wide range of compromises, budget shortfalls, and design-by-committee missteps ultimately produced a Shuttle that was horrifically complex, unsafe, only partially reusable, suboptimal for most tasks, and more expensive to launch than Saturn V.
The Space Shuttle was ultimately a beast to refurbish and “reuse”, often requiring an almost complete disassembly and reassembly and extensive rework on most propulsive components. Partially due to those extreme shortcomings and a catastrophically fatal launch failure just five years after its debut, the Shuttle was never able to get anywhere close to realizing its limited but still strong potential, including a maximum orbital longevity of just two or so weeks.
As a result, NASA went from Saturn I, Saturn V, and CSM – a combination that enabled single-launch space stations, multi-month crewed spaceflights, and the Apollo Program – to the Space Shuttle, an anchor that yanked the space agency’s human agency ambitions back to low Earth orbit (LEO). In the Space Shuttle’s defense, NASA did eventually join an international initiative to build the International Space Station (ISS), a program the Shuttle supported with several dozen launches of crucial modules, components, and supplies.
However, had NASA been able to continue the Skylab program with Saturn and CSM, a space station with a habitable volume similar to the 2021 ISS could have been completed in a mere three launches, compared to no less than 30 launches to build the ISS.
Regardless, after an unfortunate and unnecessary 47-year pause, SpaceX – with NASA funding – has returned the space agency and the US to its legacy of envelope-pushing. On the heels of 20 successful uncrewed Cargo Dragon missions to and from the ISS over the last 9 years, all of which spent around a month in orbit, SpaceX’s third Crew Dragon launch has already beat the US record for crewed spacecraft longevity on orbit and is ultimately poised to double it before the mission’s end.
-->Crew Dragon’s Crew-1 astronauts even celebrated the milestone in orbit with (albeit virtually) Ed Gibson, one of the three astronauts that set Skylab-4’s record 47 years prior. Additionally, in a pleasing coincidence, Skylab-4 and SpaceX Crew-1 nearly launched on the same day, meaning that tomorrow (February 8th) is the true 47th anniversary of the Skylab-4 mission’s reentry and splashdown.
All told, all operational Crew Dragon missions – of which Crew-1 is the first – are scheduled to spend approximately 180 days in orbit between launch and reentry. As the first US spacecraft (and first private spacecraft) to attempt such a long spaceflight, there is obviously some uncertainty and no guarantee that this first try won’t be cut short, but odds are in SpaceX’s favor that Crew Dragon capsule C207 will depart the ISS without issue and safely return its four-astronaut crew back to Earth sometime in May 2021.

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.
