Rocket Lab briefly catches Electron booster with a helicopter on first try
In a significant achievement, public launch provider Rocket Lab has – with a few caveats – successfully used a helicopter to catch the booster of its Electron rocket out of mid-air on the very first attempt.
The company began working on ways to recover and reuse the booster of its tiny Electron rocket in 2019, going back on a promise repeatedly made by founder and CEO Peter Beck in the years prior. Due to just how small the Electron rocket is, it was generally assumed that Beck wasn’t wrong to avoid attempting to recover or reuse its parts of it. However, that attitude quickly changed when the need to ramp up launch cadence became a leading priority. Soon after, Beck revealed that Rocket Lab engineers had looked more carefully at the problem and concluded that Electron booster recovery was more feasible than assumed.
Once the problem was no longer deemed insurmountable, the allure of reuse – intrinsically multiplying the effectiveness of any given production line if done right – was irresistible.
While the change in attitude made Rocket Lab the second company after SpaceX to begin seriously developing the ability to recover and reuse orbital-class liquid rocket boosters, the approach it would need to take for a rocket as small as Electron was almost nothing like that used by Falcon boosters. Instead of multiple in-flight engine ignitions, supersonic retropropulsion, steerable fins, and a propulsive landing, Electron would rely on several parachutes to slow itself down, use small thrusters (not unlike Falcon) for attitude control, and be actively captured out of mid-air by a crewed helicopter.
Ironically, demonstrating the sheer size gap between Electron and Falcon 9, Electron booster recovery more closely resembles Falcon 9 fairing recovery. Weighing in at around one ton (~2200 lb) per half, or about as heavy as an entire Electron rocket booster, each fairing half mainly just controls its attitude with cold-gas thrusters while passively reentering Earth’s atmosphere. Fairing halves then deploy a GPS-guided parafoil and gently splash down on the ocean surface before being fished out of the water by a waiting ship.
That is exactly how Rocket Lab trialed Electron recovery on several prior attempts, fishing intact boosters out of the Pacific Ocean after gentle ocean landings. For a while, SpaceX even attempted to catch fairings out of mid-air – albeit with a highly-modified ship and net instead of a helicopter and hook. However, when the company realized it could easily reuse fairing halves that landed in the ocean, it fully abandoned catch attempts.
-->In Electron’s case, it’s no surprise that Rocket Lab still pursued catch-based recovery while SpaceX was simultaneously giving up on the practice. Put simply, it would be incredibly difficult to reliably and affordably reuse a liquid rocket booster – and liquid rocket engines especially – after dunking them in saltwater.
That’s also why the success of Rocket Lab’s first operational catch attempt has caveats. While the company did successfully catch the booster out of mid-air, the pilot – who holds final authority for the sake of safety – observed unusual behavior not seen during testing after hooking Electron and chose to release the booster early. Thankfully, it still managed a soft landing in the ocean and was recovered by ship, but despite statements from Beck to the contrary, that seawater exposure will almost certainly make it impossible to fully reuse. To call the attempt a total success, the helicopter would have needed to drop the booster off on the recovery ship’s deck, fully avoiding a bath.
Above all else, even if the catch didn’t last, Rocket Lab successfully launched 34 small satellites and payloads into orbit for several paying customers and briefly caught the booster that launched them with a helicopter. The attempt was arguably far more successful than not and likely leaves Rocket Lab just a little more practice and a few small optimizations away from a perfect recovery. Then the company can shift its focus to the next goal: the first Electron booster reuse.

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.
