SpaceX tests extra-fast ocean landing, celebrates 50th launch
The happy tragedy of 1044
SpaceX has successfully completed the 50th launch of Falcon 9 a bit less than eight years after its 2010 debut, and has done so in a fashion that almost perfectly captures the veritable tsunamis the company has begun to make throughout the global aerospace industry. After a duo of delays due to hardware issues and range conflicts, this evening’s launch successfully placed Hispasat 30W-6 into a geostationary transfer orbit (GTO), where the massive ~6100 kilogram communications satellite will now spend several months raising its orbit to around 36,000 km (22,000 miles) above Earth’s surface.
Falcon 9 flight 50 launches tonight, carrying Hispasat for Spain. At 6 metric tons and almost the size of a city bus, it will be the largest geostationary satellite we’ve ever flown.

Aside from becoming the heaviest commsat the company has yet to launch into GTO, the mission’s anticipated landing attempt stirred up quite a bit of intrigue and uncertainty in the spaceflight fan community. Stormy Atlantic seas, partially connected to the chaotic weather recently seen on the East coast, proved to be far too dangerous for SpaceX’s eastern recovery fleet and its drone ship, OCISLY, and they returned to Port Canaveral around 48 hours ago, under the watchful eyes of many anxious SpaceX followers. Tragically, this means that the brand new Falcon 9 booster (B1044) – originally expected to attempt perhaps the most difficult landing yet – had to be expended. Although the booster went through its paces as if it were preparing to land, it found no drone ship beneath it once it reached sea level, and subsequently dunked into the stormy Atlantic seas.
However, due to the last-minute nature of SpaceX and Hispasat’s decision to expend the booster rather than delay for better recovery conditions, launch technicians at Pad 40 simply did not have time to remove the rocket’s iconic landing legs and valuable titanium grid fins – the first time their titanium iteration has been chosen for a Falcon 9 to resist extreme reentry heating. Due to massive swells, recovery of even pieces of the expended booster – theoretically following a soft landing – will not be possible, as no SpaceX recovery vessels remained at the planned point of touchdown 400 miles off the Florida coast. Notably, following the successful inaugural flight of Falcon Heavy, CEO Elon Musk stated that upgraded titanium grid fins were “super expensive” and unequivocally “the most important thing to recover.” SpaceX’s decision to expend Falcon 9 B1044 without even sparing the time to remove the booster’s recovery hardware and titanium fins demonstrates just how focused the company is on its customers’ needs. In the case of geostationary communications satellites like Hispasat 30W-6, launch delays on the order of a few days can cause millions of dollars of financial harm to the parent company – each day a satellite spends on the ground orbit is also a day with no revenue generation, a less-than-thrilling proposition to shareholders.

B1044 sadly lost any hope at a second flight, but the data SpaceX gathered from its uniquely fast reentry and attempted soft-landing will hopefully pave the way for the recovery of Falcon 9 and Heavy boosters after all but the heaviest satellite launches. GovSat-1, a launch that saw its flight-proven booster famously survive a similarly hot landing in the ocean, was the first largely successful test of this new and experimental method of more efficiently recovering Falcons. By igniting three of its nine Merlin 1D engines instead of the usual single engine while landing, Falcon boosters can theoretically reduce the amount of fuel needed to safely land, fuel savings that can then be used to push its payloads higher and faster. However, the downsides of this approach are several. With three times as many engines igniting at landing, the margin of error for a successful landing becomes downright miniscule – the tiniest of problems with ignition, throttle control, or guidance could cause the rocket to smash into the drone ship at considerable speed. Additionally, triple the landing thrust would subject the booster to as much as 10Gs of acceleration (10 times the force of Earth’s gravity), forces that would almost instantaneously cause the average human (and even specially trained fighter pilots) to black out.
This rocket was meant to test very high retrothrust landing in water so it didn’t hurt the droneship, but amazingly it has survived. We will try to tow it back to shore. pic.twitter.com/hipmgdnq16

Regardless of 1044’s untimely demise, another successful mission for SpaceX is purely positive. Happy customers make for a happy company, and SpaceX has achieved an incredible consistency of success in the last year alone. The loss of a new, potentially-reusable Falcon 9 booster is sad, but it only serves to foreshadow the imminent introduction of Falcon 9 Block 5, an upgrade hoped to realize Elon Musk’s decade-old dream of rockets that can be reused as many as 10 times with minimal refurbishment, and 100 times with maintenance. That debut could occur as early as April, just a month away.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->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-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

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.
