SpaceX to attempt “hot” Falcon 9 landing at sea in spite of heavy payload
Although SpaceX’s launch of PAZ and two Starlink demo satellites has been pushed back to Thursday by weather concerns, work back on the East coast is continuing apace in preparation for the Sunday, February 25 launch of an exceptionally heavy communications satellite.
Updated February 24: SpaceX has postponed Sunday’s launch, as it attempts to conduct additional testing on the fairing’s pressurization system. “Once complete, and pending range availability, we will confirm a new targeted launch date”, notes SpaceX.
Eloquently deemed Hispasat 30W-6 (1F), the hefty 6000+ kg spacecraft will be sent to geostationary transfer orbit (GTO) atop a brand new Falcon 9 rocket, quite a rare occurrence in the last several months. Based on the satellite’s considerable mass and public understand of Falcon 9’s performance, it was reasonably assumed that the rocket would need to launch in an expendable configuration to lift its payload to the proper orbit. However, in an unexpected turn of events, local observers with access to Cape Canaveral Air Force Base (CCAFS) or Kennedy Space Center (KSC) have observed what unequivocally appear to be grid fins and landing legs attached to the fresh Falcon 9, Booster (B)1044.

Further corroborating this evidence of an imminent landing attempt, Notices to Airmen (NOTAMs) have been published that indicate a possible landing location for the SpaceX rocket. NOTAMs are used to instruct aircraft and boats of potentially hazardous areas that must be avoided within a certain time frame – for those of you with memories of scrubbed launches caused by wayward boats or aircraft, these notices are what those offending individuals were supposed to be cognizant of. NASASpaceflight.com forums user Raul has kindly maintained a custom Google Maps fork that is regularly updated with data provided in NOTAMs, and serves as an invaluable visualization for those of us that do not pilot boats or planes quite as frequently as others.
SpaceX drone ship Of Course I Still Love You (OCISLY) has taken quite a beating in the past few months – most recently she was nearly speared by Falcon Heavy’s 300+ mph center core. Nevertheless, the storied vessel has been relentlessly repaired and maintained by SpaceX’s crew of recovery fleet technicians and can be expected to leave its Floridan Port Canaveral berth within the next 24 hours – so long as the company intends to attempt recovery of Falcon 9 B1044.

As launch photographer Tom Cross works to acquire a license that would allow him to place remote cameras nearby the drone ship, viewers can capture the drone ship landings on SpaceX’s webcast. We’ll continue to provide on-the-ground coverage of both rocket launch and landings.
-->Meanwhile, back on the West coast, photographer Pauline Acalin is busy covering SpaceX’s launch of PAZ and two Starlink demo satellites. Due to slightly off-nominal upper level winds, just barely violating Falcon 9’s engineering margins for wind shear, the launch attempt earlier this morning was scrubbed and pushed back 24 hours, now NET 6:17am PST Feb. 22. Although the flight-proven booster flying with PAZ will be expended in the Pacific Ocean after launch, it appears likely that the launch will feature SpaceX’s first full-on attempt at recovering a payload fairing half intact.
SpaceX’s live coverage will begin at the livestream below approximately 15-20 minutes before launch.

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.
