SpaceX on track for biweekly launch cadence in the remainder of year
Weekly rapid reuse launches expected by 2019

Following a weekend of extraordinary accomplishments, seeing SpaceX flawlessly execute two missions – one with a reused first stage – in just over 48 hours of each other, the company has capitalized on a uniquely successful weekend and year and offered information about their future plans.
The launch of BulgariaSat-1 and Iridium-2 on Friday and Sunday respectively marked the eight and ninth launches of 2017 for SpaceX, and officials at the company are reportedly expecting to launch approximately 24 missions this year, meaning 15 more to come over the next 6 months. Given the recent demonstration of 48 hour launch cadence and a more regular schedule of biweekly launches in the past few months, an expectation of 15 more launches for 2017 lines up perfectly with a cadence of two launches a month from LC-39A Cape Canaveral and three Iridium launches from Vandenberg, which happens to be exactly what is currently manifested.
Originally manifested for up to 27 launches this year, successfully launching 24 missions, one of which might be the inaugural flight of Falcon Heavy, would be extraordinarily hard to ignore in an industry that has compared the launch industry to manufacturing beverage containers and argued that reuse is only sustainable with more than 20 launches a year on a company’s manifest.

SpaceX is now likely to undertake 24 launches this year, but the company also revealed this weekend that it intends to achieve a regular weekly launch cadence (52 launches per year) as soon as 2019. In a recent article, I speculated that we might begin to see regular weekly launches once both LC-39A and LC-40 were active, and that appears to be nearly correct. If SpaceX is to regularly conduct weekly launches by 2019, it is bound to begin shrinking its two week cadence as soon as is safe and possible. This will likely occur once Falcon Heavy has successfully flown several times from LC-39A, thus freeing SpaceX to deem the vehicle operational and less at risk of destroying one of their two Eastern pads.
There is also a tentative understanding that SpaceX is striving to construct and activate their planned Boca Chica, Texas launch complex by 2019. The successful reactivation of LC-40 and subsequent modification of LC-39A for Falcon Heavy will leave the brunt of SpaceX’s launch complex maintenance and construction teams free to focus entirely on the Texas facility sometime late this year or early next year, meaning that Boca Chica pad activation could certainly occur as early as 2019. This would leave the company with two fully operational all-purpose launch pads dedicated to Falcon 9 launches if they choose to retain LC-39A solely for Falcon Heavy and Commercial Crew launches, allowing them to reach weekly cadences even before the launches of Falcon Heavy, Commercial Crew contracts, and Vandenberg launches are accounted for.
One crucial factor playing into SpaceX’s ability to launch 52 times in a year is of course reusability, as it is hard to imagine SpaceX more than doubling their Falcon manufacturing capabilities in under a year and a half. Likely no coincidence, SpaceX simultaneously offered information to insurance underwriters about the increasing speed of their ability to launch, recover, and reuse first stages. More specifically, a spokesman of the company stated that the reuse of BulgariaSat-1’s Falcon 9 1029 took considerably less than half as long as the inaugural reuse of the stage that launched SES-10 earlier this year, implying that refurbishment and quality assurance checks for 1029 took something like four or five months total.
With SpaceX having debuted new titanium grid fins intended to speed up reuse on the Sunday launch of Iridium-2, the company is well on its way to transferring over to Block 4 (upgraded engine performance) and possibly Block 5 of Falcon 9 later this. Block 5 is expected to introduced major changes meant to replace aspects of the current Falcon 9 that require major refurbishment after recovery. Musk detailed these changes several months ago in a Reddit AMA (Ask Me Anything), mentioning that reusable heat shielding around the engines, improved landing legs, and titanium grid fins were the main aspects of a Block 5 of Falcon 9 meant to offer rapid reuse without refurbishment. In June 22nd interview on the Space Show, Gwynne Shotwell reiterated that this “final” version of Falcon 9 is expected to be able to launch, land, and relaunch with barely more than a thorough once-over, and ought to be capable of flying a dozen missions at least.

This final piece of the puzzle of weekly cadence fits in quite nicely. With a possible introduction date for Block 5 of late 2017 or early 2018, SpaceX will likely end production of Block 3 by the end of this year and transfer over entirely to the easily reusable Block 5. Assuming a continuing a trend of increasingly reuse-friendly customers, Hawthorne production capacity of approximately 20 Falcon 9s per year, and a plausibly significant reduction in launch costs due to more rapid and complete reuse, SpaceX could find themselves at the start of 2019 with a dozen or more launch vehicles that are each capable of conducting upwards of 10-12 highly affordable launches each.
Let there be no doubt: these are incredibly optimistic and difficult goals for the company to achieve on the timescale they have provided. However, given the number of beneficial changes likely to soon be made to both the launch vehicles and SpaceX’s manufacturing, launch, and refurbishment facilities in the next 6-12 months, those goals are realistically achievable, albeit with some likely delays. Regardless, things are beginning to get rather intense for SpaceX and for the launch industry in general.
Keep your eyes peeled for upcoming Teslarati coverage of SpaceX’s next July 4th launch and its static fire that is scheduled for as soon as this Thursday.

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.
