SpaceX shows off largest window in space after spectacular Inspiration4 launch
SpaceX has revealed the first on-orbit view of the largest window every launched on a rocket – and provided an update on the status of its first private astronauts – after Wednesday night’s spectacular Inspiration4 launch.
Around 8:03 pm EDT on September 15th (00:03 UTC 16 Sept), Falcon 9 successfully lifted off from Kennedy Space Center, sending four private astronauts – the world’s first all-private crew on an orbital spacecraft – into low Earth orbit (LEO). In the 18 hours since, now twice-flown Crew Dragon spacecraft Resilience has successfully boosted its orbit from around 200 km (~120 mi) to around 580-590 km (360-365 mi) – the highest altitude ever reached by private astronauts and highest any human has traveled in approximately two decades (19 or 22 years).
Now safely in orbit on what’s expected to be a three-day journey in space, SpaceX also reports that Inspiration4 commander Jared Isaacman, pilot Sian Proctor, medical officer Haley Arceneaux, and specialist Christopher Sembroski are all “healthy, happy, and resting comfortably.” As early as this afternoon, the four private astronauts will wake up and potentially experience Crew Dragon’s cupola – the largest window by surface area ever flown to space or orbit – for the first time.
Following a spectacular post-sunset launch and a nearly five-hour webcast covering it, many have noted that SpaceX and Inspiration4 have practically gone silent after reaching orbit and that unlike Crew Dragon’s past three NASA astronaut launches, there has been no live coverage – and virtually no news at all – of the in-space cruise phase. It’s quite possible that one, several, or all of the four Inspiration4 crew members – all spaceflight rookies – are experiencing the common and uncomfortable “space adaptation syndrome,” referring to extreme nausea and discomfort as many as two-thirds of astronauts experience during their first hours or even days in microgravity.
If that’s the case, it would be no surprise that the crew might want privacy for the first 12-24+ hours and more generally to simply enjoy being in orbit – and higher than all but a few dozen humans have ever traveled – with some degree of peace. A great deal of photos and videos are still expected – but as part of Netflix’s Countdown documentary and only after the crew returns to Earth, rather than the live, immediate coverage SpaceX’s other Crew Dragon missions have had.

With another two days left in orbit, the Inspiration4 crew are scheduled to perform a few relatively minor experiments – mostly focused on health – but are mostly expected to simply enjoy being in space. Once they wake up and are able to open Dragon’s forward bulkhead hatch, they’ll get to experience the first-ever views out of the spacecraft’s cupola. A camera inside the nosecone cover will allow them to take some truly unique self-portraits with Earth, space, and even the Milky Way as backdrops – only really comparable to the occasional self-portraits taken by astronauts during spacewalks.
With any luck, SpaceX or Inspiration4 will share a few of those special photos later today. Barring on-the-fly changes, the four private astronauts are scheduled to return to Earth on Saturday evening. Stay tuned for further updates on the historic mission.

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.
