SpaceX might launch first Starlink Gen2 satellites next week
Update: It no longer appears that SpaceX’s last Starlink launch of the year will carry true V2 or V2 Mini satellite prototypes for its next-generation Starlink constellation. That has only deepened the layers of mystery surrounding the mission.
SpaceX has told the US Federal Communications Commission (FCC) that it plans to begin launching its first next-generation Starlink Gen2 satellites before the end of 2022.
The FCC only just granted SpaceX partial approval of its Starlink Gen2 constellation, which has been under review since May 2020, in late November 2022. Just a week or two later, in several filings asking the FCC to expedite Special Temporary Authority (STA) requests that would allow it to fully test and communicate with its first next-generation satellite prototypes, SpaceX said [PDF] that it “anticipates that it will begin launching Gen2 satellites before the end of December 2022.”

In most of the main STA requests filed in early December, SpaceX appears to be asking the FCC to add Starlink Gen2 satellites as approved points of communication for user terminals and ground stations that are already licensed. Those include its new high-performance dishes, newer base-model dishes (both fixed and in motion), and first-generation (round) dishes. While the FCC’s recent actions on Starlink do not raise confidence in its consistency, objectivity, and rationality, these requests should be shoe-ins.
SpaceX also wants permission to activate Very High Frequency (VHF) beacons that are meant to be installed on all Starlink Gen2 satellites. Those beacons would serve as a backup to existing telemetry, tracking, and command (TT&C) antennas and decrease the odds of a total loss of control by ensuring that SpaceX can remain in contact with Gen2 satellites regardless of their orientation – an ability that would obviously improve the safety of Starlink orbital operations.
Given how unusually long it took the FCC to review SpaceX’s Starlink Gen2 applications and how arbitrarily strict it was with its partial Gen2 license grant, it’s hard to say if the FCC will grant these STA requests or how long it will take if it does. SpaceX finds itself in a strange position where the FCC has given it permission to begin launching up to 7500 Starlink Gen2 satellites, but has not granted SpaceX permission to use those satellites to communicate with user terminals.
To the FCC’s credit, a constellation operator has never been ready to launch satellites less than one month after launches were approved, and it’s likely that the processes to ensure those satellites can be properly used after launch are ongoing. Additionally, because of the FCC’s arbitrary license restrictions, SpaceX is not allowed to launch or operate any Starlink Gen2 satellites outside of a narrow range of altitudes (475-580 km). After launch, Starlink Gen2 satellites will likely take around two or three months to reach those operational orbits, only after which can SpaceX begin using them in earnest. As long as the FCC approves most of SpaceX’s December 2022 STA requests, the disruption to Starlink Gen2 deployment and on-orbit testing should thus be limited.
Next week?
While SpaceX’s schedule targets can often be easily dismissed for future projects, there is evidence that SpaceX will actually attempt to launch the first Starlink Gen2 satellites before the end of the year. Earlier this month, SpaceX received permission to communicate with a Falcon 9 rocket for a mission called Starlink 5-1. One of five orbital ‘shells’ that make up SpaceX’s first-generation Starlink constellation does technically have zero satellites and is awaiting its first launch. But that shell (Group 5) is polar, meaning that its satellites will orbit around Earth’s poles, and the STA license the FCC granted indicates that this launch will be to a more equatorial inclination, which would not make sense for a Group 5 launch.
It’s thus possible that SpaceX decided to repurpose the STA for its first Starlink Gen2 launch, which the company cannot currently launch to an inclination other than 53 degrees – roughly the same trajectory indicated by the document. Starlink Gen1 has two 53-degree shells, Group 1 and Group 4, and both are nearly complete and would likely be called Starlink 1-XX or 4-XX in FCC filings. Combined with SpaceX stating in its VHF beacon STA request that initial Starlink Gen2 launches will start in “late December 2022,” and unofficial manifests indicating that SpaceX has a Starlink launch scheduled as early as December 28th, it certainly appears that first Gen2 satellites will reach orbit later this year.
More likely than not, they will be Starlink “V2 Mini” satellites – a downsized variant created to maximize the efficiency of Falcon 9 Starlink Gen2/V2 launches while SpaceX’s next-generation Starship rocket remains stuck on the ground. The Starship-optimized Starlink V2 satellites SpaceX initially hoped would be the only version reportedly weigh about 1.25 tons (~2750 lb) and measure roughly 6.5 by 2.7 meters (21 x 9 ft). According to an October 2022 FCC filing, Starlink V2 Mini satellites will still be several times larger than today’s Starlink V1.5 satellites, weighing up to 800 kilograms (~1750 lb) and measuring 4.1 by 2.7 meters (13.5 x 9 ft).
SpaceX says Starlink V2 Mini satellites will also have a pair of massive solar arrays with a total array of 120 square meters (~1300 sq ft). Assuming V2 Mini satellites are roughly as power-efficient as V1.5 satellites and use similarly efficient solar arrays, that indicates that could offer around 3-4 times more usable bandwidth per satellite. Assuming SpaceX has again found a way to use all of Falcon 9’s available performance, each rocket should be able to carry up to 21 Starlink V2 Mini satellites to low Earth orbit.

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.
