SpaceX Starlink Gen2 mission marks Falcon 9 rocket’s 200th successful launch
A day and a half after its 200th launch overall, SpaceX’s Falcon 9 rocket has successfully launched for the 200th time.
Falcon 9 has only suffered two mission-related failures in flight: one partial failure in 2012 and a catastrophic failure in 2015. Falcon 9’s 2015 failure entirely destroyed the rocket and its cargo-carrying Dragon spacecraft before they reached orbit. Its 2012 failure only doomed a secondary Orbcomm satellite payload, while the primary mission – a Cargo Dragon supply delivery for NASA – was technically successful.
Excluding partial failures, Starlink 5-3 was SpaceX’s 200th successful Falcon 9 launch since the rocket debuted in June 2010. Indicative of the company’s aggressive launch cadence as of late, Falcon 9 completed its 200th launch overall (199th success) less than two days prior, on January 31st.

Starlink 5-3 was SpaceX’s third launch for its Starlink Gen2 constellation, though the mission carried 53 ordinary Starlink V1.5 satellites. Oddly, the Starlink 5-2 mission carried 56 Starlink V1.5 satellites and set a new record for the heaviest SpaceX and Falcon 9 payload on January 26th. Just a few weeks prior, Falcon 9’s Starlink 5-1 launch carried 54 satellites – a curious amount of variability for three missions launching the same type of satellite to similar orbits.
As previously discussed on Teslarati, perhaps the single most important upgrade meant for SpaceX’s Starlink Gen2 constellation was a move to larger V2.0 satellites with almost a magnitude more usable bandwidth. But full-size Starlink V2.0 satellites can only be efficiently launched on SpaceX’s next-generation Starship rocket, which is likely at least 6-12 months away from its first satellite launch. SpaceX also told the FCC that it was building a mid-sized Starlink V2.0 satellite that could be launched on its existing Falcon rockets, but those compromised satellites have yet to appear.
Instead, SpaceX is launching Starlink V1.5 satellites under its Gen2 constellation license, which currently allows the company to launch and operate 7,500 of the almost 30,000 satellites it requested permission for. SpaceX’s Starlink Gen1 constellation is still ~1100 satellites away from completion. One possible explanation is that nearly all of the missing Gen1 satellites are headed to polar or semi-polar Earth orbits. Those polar satellites will spend far more time over regions of Earth with few to no Starlink customers, making them less capital-efficient than their mid-latitude siblings.
In other words, polar Starlink satellites – while necessary to ensure truly global coverage – effectively add less capacity to SpaceX’s network than they would if launched to midlatitude orbits. That appears to be exactly what SpaceX is currently doing with Starlink Gen2. The mid-latitude ‘shells’ of its Gen1 constellation are close to full, so the company is launching Starlink V1.5 satellites under its Gen2 license to increase the capacity of the overall network as quickly as possible.
Eventually, SpaceX will almost certainly replace those smaller, less capable V1.5 satellites with V2.0 satellites. In the near term, though, SpaceX has concluded that an inefficient gap-filler is better than waiting for a more optimal solution. It should not take long for the impact of Gen2 launches to be felt. Once the 163 ‘Gen2’ satellites launched in the last five weeks reach operational orbits, they will increase Starlink’s mid-latitude capacity by more than 5%.

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.
