A SpaceX Falcon 9 rocket has successfully launched 51 upgraded laser-linked Starlink satellites from its Vandenberg Space Force Base (VSFB) – the first mission of its kind out of the company’s west coast launch facilities.
Known as Starlink Group 2-1, the mission debuted the operational design of new V1.5 Starlink satellites with laser interlinks that will eventually let the constellation route its own communications almost anywhere on Earth – regardless of ground station locations. Aside from potentially allowing SpaceX to flout local regulations in countries with oppressive communications restrictions, firewalls, or censors, those lasers will also give Starlink the ability to easily deliver internet to moving vehicles – including aircraft traveling over oceans – and in even the remotest locations with no ground infrastructure for hundreds of miles.
Independent of its main purpose, the Starlink 2-1 mission also saw SpaceX tie its internal Falcon booster reusability record. Following in the footsteps of younger booster B1051, Falcon 9 B1049, which debuted in September 2018, successfully completed its tenth orbital-class launch and landing with Starlink 2-1. Originally scheduled to launch as early as July, apparent hiccups mass-producing new Starlink V1.5 satellites and their laser interlinks delayed the mission by about two months, causing SpaceX to launch just once in 11 weeks preceding the mission.
In comparison, Falcon 9 B1051 debuted in March 2019 and became the first booster to cross the ten-flight mark in May 2021, just 26 months later. B1049 took almost exactly 36 months to accomplish the same feat – almost 40% slower but still faster than any of the four NASA Space Shuttles that successfully reached similar milestones.
SpaceX also says that Starlink 2-1 is the 24th time the company has successfully launched a flight-proven Falcon 9 payload fairing, reusing a normally expendable component that CEO Elon Musk once likened to a pallet of $6 million in cash. Ultimately, the company gave up on efforts to catch parasailing fairing halves out of the air with giant ship-based nets and has instead refocused on perfecting the reuse of fairings that gently land in the ocean. For the most part, that’s been accomplished by designing Starlink satellites themselves to tolerate a much dirtier, louder launch environment than most other spacecraft, letting SpaceX remove sponge-like foam sound suppression tiles normally found inside fairings and worry less about needing to deep-clean the giant nosecones.
Nevertheless, SpaceX has technically launched 150+ commercial payloads – and one major geostationary commsat (SXM-7) – over three launches with flight-proven fairings, suggesting that there is a path to wider commercial acceptance of the brand new technology and the direct cost savings it brings.
With Starlink 2-1 safely in orbit, SpaceX now likely operates more space-based laser interlinks than the rest of the world combined. Eventually, once enough satellites with laser links are in orbit, SpaceX will be able to dramatically expand Starlink coverage almost independent of the construction of new ground stations – a heavily bureaucratic process that has proven to make for agonizingly slow progress in a number of the 15+ countries with active service. Instead of requiring that the satellite a given user terminal (dish) is communicating with be in direct line of sight of a ground station dish to route a user’s communications, thus connecting them to the internet, a constellation with widespread lasers will allow a dish’s active satellite to relay that connection through other satellites.
As a result, ground stations can be significantly further away from the users they end up supporting. Further, given that SpaceX has no plans to stop building new ground stations despite the bureaucratic hell it can involve, a well-linked Starlink constellation will ultimately be able to beat most wired connections by using lasers to route user communications to the ground stations closest to the real-world servers or services they’re trying to access.
Stay tuned for updates on SpaceX’s next polar Starlink launch(es) with ‘space lasers.’

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.
