SpaceX’s twelfth launch and ninth recovery of 2017 ready for a Thursday liftoff
After conducting a successful static fire on Saturday, August 19, SpaceX is ready to undertake their 12th launch of 2017 and the 40th launch of Falcon 9.
The launch window begins Thursday, August 24, at 11:51 a.m. PST and lasts for approximately 40 minutes, allowing for flexibility in the event of a simple scrub or abort. It will see Falcon 9 carry Formosat-5 into a sun-synchronous orbit approximately 600-1000km above the surface of the Earth, where it will be able to best carry out its duties of remote sensing and Earth observation. Developed by Taiwan’s National Space Organization, the satellite will be the country’s first indigenous remote sensing platform in orbit.

Formosat-5 was originally contracted to launch aboard Falcon 1, SpaceX’s first orbital launch vehicle. Much smaller than Falcon 9, the original choice of launch vehicle made more sense given the satellite’s small mass of approximately 500 kilograms. After many years of delays, SpaceX had instead arranged for the satellite to be launched as a co-passenger alongside Spaceflight Industries’ first SHERPA launch, an orbital tug and dispenser that would have placed approximately 90 satellites of different sizes into unique orbits. However, after SpaceX experienced two catastrophic failures of Falcon 9 within a period of less than a year and a half, Spaceflight chose to rebook all of those passenger satellites on other launches. In spite of the apparent drama, Spaceflight and SpaceX still plan to work together in the future and SpaceX has several SHERPA launches scheduled over the next several years.
Given the size of Formosat-5 compared to Falcon 9, the satellite will be downright minuscule inside the vehicle’s cavernous payload fairing. While it has been reasonably argued that the dedication of an entire Falcon 9 for a 500 kg payload hints at a significant level of inefficiency in the launch industry, the small payload will allow Falcon 9 to attempt an unusually easy recovery on the ASDS Just Read The Instructions. The fifth West-coast mission for SpaceX, the Falcon 9 will lift off from Vandenberg Air Force Base, California before landing in the Pacific Ocean around ten minutes after launch. The choice to land in the ocean has sparked curiosity among fans after photos suggested that SpaceX’s West coast landing zone is complete and all necessary permits and environmental impact reviews have been successfully completed.

SpaceX’s only other West-coast missions, seven contracted launches of Iridium’s NEXT constellation, are understood to be too heavy to provide the fuel margins necessary for Falcon 9 to return to the launch site for a landing. As such, the company’s West coast pad may well remain unused well into the future, and SpaceX may simply have chosen to focus their pad engineers on the far more pressing and time sensitive work going on at SpaceX’s East coast launch facilities.

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.
