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.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
