SpaceX Falcon 9 “fleet leader” returns to port after record reuse
SpaceX is well and truly 70% of the way to a longstanding rocket reusability target after successfully launching and landing the same Falcon 9 booster on seven orbital-class missions.
Known as Falcon 9 B1049, the record-breaking rocket booster and new “fleet leader” safely returned to Port Canaveral aboard drone ship Of Course I Still Love You (OCISLY) on Saturday, November 28th. Aside from a minor hiccup and 24-hour delay from a vague need for “additional mission assurance,” Falcon 9’s seventh-flight debut was as flawless as ever, simultaneously marking the rocket’s 100th launch overall and 99th success after a decade of operation.
Crystallized in May 2018 and floated many times before by CEO Elon Musk in years prior, SpaceX’s primary goal for Falcon 9 reusability has been ten flights per booster with near-zero refurbishment between launches for several years. As such, Falcon 9 B1049’s latest success means that SpaceX is just three flights away from crossing that partly symbolic but still spectacular milestone.
For as long as SpaceX and Musk have been transparent about their desire to implement reusability into orbital-class rockets, entrenched competitors like Arianespace and United Launch Alliance (ULA) have almost continuously responded with vague internal studies that conclude that changing their ways is counterproductive. Often, somewhat arbitrary figures arise, with ULA executives frequently falling back on the excuse that SpaceX-style reusability only makes financial sense if a booster fleet averages at least ten flights each.
Arianespace executives have echoed similar sentiments over the years and more recently implied that it would only ever make sense to invest in SpaceX-style reusability if the conglomerate could guarantee at least 30 launch contracts annually.
Instead of complaining and splitting theoretical hairs for the better part of a decade, SpaceX simply started working. After many tries, the first successful Falcon 9 booster landing came in December 2015. ~15 months later, SpaceX reused an orbital-class rocket booster on a commercial mission for the first time ever. Another 14 months after that, Falcon 9 Block 5 debuted with a bevy of upgrades focused on reusability and reliability, and that same Falcon 9 booster became the first to launch on three orbital-class missions just seven months later.
Falcon 9 B1049 debuted in September 2018. 26 months later, the rocket has completed its seventh successful launch and landing, averaging one orbital satellite launch every ~110 days – an impressive feat for the fourth Block 5 booster ever built. Newer boosters like Falcon 9 B1058 are already improving on the records of their predecessors, managing an average of one launch every 60-80 days.
Even if ten flights were to inexplicably become a permanent design limit for all Falcon operations, SpaceX’s current fleet of eight flight-proven Falcon 9 boosters would still be capable of singlehandedly supporting at least 54 more launches, with another 16 on top of that if two dormant Falcon Heavy side boosters are converted for single-core use. SpaceX is unlikely to stop producing Falcon boosters for at least another year or two, adding at least 6-10 more first stages to the fleet to support dozens of crucial Falcon 9 and Falcon Heavy launches over the next 5-10 years.
In simpler terms, it’s almost time for SpaceX’s competitors to move their goalposts again. If B1049 can mirror its 2020 average of one launch every ~80 days, the Falcon 9 booster could be ready for its tenth flight as early as Q3 2021 (with B1051 not far behind it).

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.
