SpaceX Falcon 9 rocket aces first launch of dozens planned this year
A SpaceX Falcon 9 rocket has aced the first launch and landing of dozens planned by the company in 2021, kicking off what could be an unprecedentedly productive year.
Lifting off at 9:15 pm EST around 45 minutes into a four-hour window, SpaceX’s first mission of the year was tasked with delivering the ~3500 kg (7700 lb) Turksat 5A communications satellite to an elliptical geostationary transfer orbit (GTO) measuring roughly 200 km (~125 mi) to 36,000 km (22,500 mi) above the Earth’s surface.* Designed and built almost entirely by Europe’s Airbus Defence and Space for Turkey, the satellite is meant to expand and upgrade communications services over wide swaths of Africa, Europe, the Middle East, and Turkey itself.
*SpaceX actually appears to have delivered Turksat 5A to what is known as a supersynchronous GTO, meaning that the apogee (furthest point from Earth) is much higher than geostationary orbit. In the case of Turksat 5A, thanks to its relatively low launch mass, Falcon 9 was able to deploy the satellite into a healthy ~290 km by ~55,000 km (180 mi x 34,000 mi) transfer orbit. In doing so, SpaceX will have substantially cut the amount of time and/or delta V (propellant) Turksat 5A will take to circularize into its operational orbit (35,786 km x 35,786 km).
It’s believed that Turksat 5A will be used to some extent for Turkish military communications, raising controversy in light of the country’s conscious decision to directly aid the aggressor responsible for igniting the brief but bloody 2020 Nagorno-Karabakh War. Controversy aside, Turksat 5A will now spend the next several months gradually raising its perigee (the lowest point of its orbit) until the satellite arrives at an operational geostationary orbit, where its health will be verified before entering service.
Although a key ground station used for telemetry, tracking, and communications (TT&C) was down during most of the second half of the mission, Falcon 9’s autonomous upper stage performed flawlessly. The orbital vehicle confirmed the completion of a successful orbit-raise maneuver once contact was made with SpaceX’s next ground station, followed by a smooth deployment of the Turksat 5A satellite around 33 minutes after liftoff.

For Falcon 9, Turksat 5A was booster B1060’s fourth launch in six months and represented the SpaceX’s 50th booster reuse since March 2017. B1060 performed as expected throughout the launch, shutting down and separating from the second stage two and a half minutes after liftoff traveling 2.3 km/s (1.5 mi/s), coasting to an apogee well above the Karman Line (100 km/62 mi), reentering Earth’s atmosphere, and touching down on drone ship Just Read The Instructions (JRTI) after 8.5 minutes in flight.
The Turksat 5A mission also marked the second time SpaceX has used a flight-proven Falcon payload fairing on a commercial satellite launch, while it was also the first time in several months that both twin fairing recovery ships Ms Tree and Ms Chief were deployed on the same mission. SpaceX says only Ms Chief was scheduled to attempt a fairing catch, while Ms Tree would instead try to scoop its assigned half out of the Atlantic Ocean.
SpaceX has three more Falcon 9 launches scheduled this month, including its first dedicated Smallsat Program mission – known as Transporter-1 – NET January 14th and two Starlink missions – V1 L16 and V1 L17 – sometime in the second half of the month.

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.
