Boeing, NASA attempt Starliner landing after missing intended orbit
During the early morning hours of Friday, December 20th, at Space Launch Complex – 41 at Cape Canaveral Air Force Station United Launch Alliance successfully launched a uniquely configured, rated for human spaceflight Atlas V rocket topped with the Boeing Starliner crew capsule to complete its inaugural Orbital Flight Test to the International Space Station (ISS).
However, following the stunning sunrise launch and successful spacecraft separation, Starliner experienced an anomaly with an automated mission event timer which hindered a crucial orbital insertion burn from being completed.
The missed burn and the resulting domino effect of consequences cut Starliner’s journey short. In a joint media teleconference held Saturday, December 21st including NASA Administrator Jim Bridenstine, Boeing senior vice president of Space and Launch Jim Chilton, and deputy manager of NASA Commercial Crew Steve Stich, it was confirmed that just 48 hours following launch Starliner is expected conclude the test flight and return for a controlled landing at White Sands Missile Range in New Mexico.
Initially, Starliner was expected to spend approximately 8 days docked on orbit with the ISS for a return journey tentatively scheduled to occur on December 28th. The lack of orbital insertion and consequential overuse of fuel consumed by smaller incremental burns performed throughout the day on Friday to place Starliner in a safe orbit all but guaranteed that the spacecraft would miss its opportunity to rendezvous and autonomously dock with the ISS, a pivotal objective of the orbital test flight. A fact that was later confirmed on Twitter by Bridenstine.
During the teleconference, Starliner was described as a healthy spacecraft that had in fact achieved circular safe orbit approximately 250km above sea level, lower than would have been achieved had the initial burn occurred as planned. As docking with the ISS was completely out of reach and Starliner remained under tight constraints of how long it could maintain free orbital flight, Boeing and NASA teams jointly decided to bring Starliner home as soon as possible.
While Starliner remained on orbit Friday and Saturday, flight controllers completed many OFT mission objectives. A number of the achievements were outlined in a statement posted to Boeing’s Starliner updates webpage.

“Entry, descent, and landing is not for the faint of heart.” – Jim Chilton
While many OFT mission objectives were successfully met during the dramatically cut short mission the entire goal of Starliner still remains. After all, Starliner is designed to ferry human astronauts safely to and from the ISS. A huge part of that is re-entering the Earth’s atmosphere and landing under survivable conditions.
Enough of Starliner’s fuel was preserved to afford multiple opportunities to safely land. Two opportunities to land at the planned site of White Sands Space Harbor on the White Sands Missile Range in New Mexico. This location may sound familiar as it is the same location where a different Starliner test capsule recently completed a pad abort test.
NASA and Boeing teams are targeting a landing attempt on Sunday 7:57 am EST (1257 GMT). Should it be needed a backup landing attempt at 3:48 pm EST (848 GMT) in the same location is also available. An anthropomorphic test dummy dressed in Boeing’s recognizable blue spacesuit inside the capsule nicknamed “Rosie the Rocketeer” is wired up with sensors to collect data reflecting the conditions a human astronaut would experience during descent.
NASA will livestream the landing attempt and recovery efforts on NASATV beginning at 5:45 am EST (1045 GMT).

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.
