(Update: scrubbed) SpaceX’s next Starlink launch to break rocket fairing reuse record
Update: SpaceX says that today’s Starlink-12 launch attempt was scrubbed due to a mysterious “recovery issue.” Liftoff from Kennedy Space Center Pad 39A is now scheduled no earlier than (NET) 1:57 pm EDT (17:57 UTC) on Friday, September 18th.
Prior to the announcement, fairing recovery ship GO Ms. Tree was spotted diverting to a North Carolina port for unknown reasons, leaving twin ship Ms. Chief to recover both fairing halves. Based on bouy data, conditions at the Atlantic Ocean fairing and booster recovery zones appeared to be moderately challenging but far from unreasonable and SpaceX has been happy to point to recovery weather for past launch delays.
SpaceX has revealed that its next Starlink launch will mark a new first for Falcon 9 payload fairing reuse, reaching a milestone that took booster reuse 18 months in less than a year.
Scheduled to lift off no earlier than (NET) 2:19 pm EDT (18:19 UTC) on Thursday, September 17th, the Starlink-12 (v1.0 L12) mission will be SpaceX’s 11th in 2020 alone and 13th overall. If things go according to plan, it could leave SpaceX’s nascent constellation just two or so months away from the beginning of the first public beta tests of Starlink internet service.
Meanwhile, Falcon 9 booster B1058 will be attempting its third launch less than four months after its flight debut, an unprecedented cadence of reuse for SpaceX. Aside from likely ensuring that B1058 becomes the proud holder of SpaceX’s first and second place records for booster turnaround (time between launches), the mission also continues an unexpected trend: the near-extinction of Falcon 9 static fire tests.
SpaceX’s first successful Falcon booster landing happened in December 2015, just a few months shy of five years ago. In March 2017, two years later, SpaceX reused a Falcon 9 booster on an orbital-class launch for the first time in history. Some 21 months after that historic milestone, SpaceX launched the same Falcon 9 booster for the third time, kicking off a relentless series of reusability firsts that continue to be made to this day.
Now, SpaceX says it’s about to launch the same Falcon 9 payload fairing half for the third time in a significant and unexpected first for fairing reuse. Constructed primarily out of a carbon fiber-aluminum honeycomb composite material, Falcon fairings are dramatically more fragile – and reaches much higher altitudes and velocities – than the boosters SpaceX has cut its teeth on recovering and reusing.
Compared to booster reuse, it’s quite the achievement. SpaceX first managed to launch the same Falcon 9 booster three times in December 2018, ~33 months after the first booster reuse. Measured from SpaceX’s first fairing reuse, completed in November 2019 as part of the first Starlink v1.0 launch (Starlink-1), the company will have managed to cross the three-flight fairing reuse barrier less than 11 months later – a full three times faster than SpaceX’s booster reuse program took to achieve the same milestone.
Additionally, prior to SpaceX’s September 16th reveal, it was purely up to speculation whether the company would be able to reuse Falcon fairing halves more than once, particularly when a given fairing half is only fished out of the ocean. If successful, Starlink-12 will prove that Falcon fairing halves can be reused at least three times regardless of whether SpaceX was/is able to catch said halve in a recovery ship’s net.
No more static fires?
Meanwhile, SpaceX appears to be turning a major corner on Falcon 9 launch operations. Of all 93 Falcon 9 launches since the rocket’s June 2010 debut, every single one has been preceded by a combined wet dress rehearsal (WDR) and static fire test a few days or weeks prior to liftoff. Effectively simulating a launch 1:1 up to the exact moment before liftoff, SpaceX has used static fires to verify vehicle health and firewall minor quality assurance lapses for as long as it’s been launching rockets.
In a major operational change that has almost flown under the radar, SpaceX appears to have killed the practice of universal prelaunch static fires beginning with Starlink-8 in June 2020. Including Starlink-8, of the seven launches SpaceX has completed in the last three months, just three (GPS III SV03, Starlink-9, and Starlink-10) included Falcon 9 static fire tests prior to liftoff. A step further, two of the four static fire-free launches were for major commercial missions – not retiring risk on SpaceX’s own Starlink launches, in other words.
As of today, Falcon 9 has completed 65 successful launches since the last catastrophic vehicle failure (Amos-6, September 2016) and 74 consecutively-successful launches if Amos-6 (which never lifted off) is excluded. As of 2020, it’s the most reliable US launch vehicle currently in operation, surpassing ULA’s Atlas V several months ago. In fewer words, it’s not actually surprising (in retrospect) that SpaceX has begun to relax its position on static fires – especially considering that there isn’t another launch provider on Earth that static fires rockets before every launch.
More likely than not, SpaceX will continue to static fire Falcon 9 and Heavy boosters at the launch pad before their flight debuts and upon customer request. If launch or post-flight inspection data offer reason(s) for concern, SpaceX may still choose to static fire boosters out of caution. Additionally, SpaceX shows no signs of ending the practice of performing full booster static fires in McGregor, Texas as part of acceptance testing, still leaving it a step beyond traditional rocket manufacturers, which only static fire individual engines.
Regardless, SpaceX’s 13th Starlink launch will be streamed live as usual, with coverage beginning around 15 minutes prior to liftoff.

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.
