SpaceX COO says Starlink is just five launches away from “full global connectivity”
The day before SpaceX aced its eighth Starlink launch in three months, President and COO Gwynne Shotwell implied that the company’s constellation of satellites could achieve “full [global] connectivity” just a handful of months from now.
Speaking at Satellite 2021’s “LEO Digital Forum” on April 6th, Shotwell revealed that SpaceX hopes to cross that milestone a few months after a total of 28 operational Starlink launches have been completed. Around 25 hours after her panel appearance, SpaceX launched its 490th Starlink satellite of the year, more or less wrapping up the first quarter of 2021.
SpaceX’s April 7th Starlink launch and booster landing was the 23rd successful launch of operational ‘v1.0’ satellites since they began flying in November 2019. All told, of the 1383 operational satellites launched by SpaceX in those 17 months, some 1369 are still in orbit, at least 1356 are functioning as expected, and more than 900 have reached their final orbits and are operational. Another 400 appear to be in long-term parking orbits dozens to hundreds of kilometers below their operational 550 km (~340 mi) ceiling, the purpose of which is unclear.
Once the 400-500 satellites now in low parking orbits reach whatever orbital parameters they’re waiting on, it’s unlikely to take more than two or three months for them to boost up to an operational altitude. Starlink-23 added another 60 around 250 km (155 mi). All told just the satellites SpaceX has in parking orbits are several times larger than the next largest constellations.
Given Shotwell’s 28-launch comment and a general idea of SpaceX’s 2021 launch cadence targets, it’s possible to extrapolate to a reasonably accurate timeline for the constellation to reach a point of “full connectivity globally” – albeit with a few caveats. First, it’s unclear what exactly the SpaceX President and COO meant with that phrase, given that SpaceX will require a substantial number of polar orbit satellites before Starlink can truly cover every single inch of Earth’s surface.
If Shotwell is including one or more dedicated polar Starlink launches in her rough 28-launch estimate, Starlink’s global connectivity timeline is effectively a complete mystery until SpaceX offers more information on its plans to build out that segment of its constellation. If she isn’t accounting for total polar coverage and means something akin to “full connectivity” for ~99% of the global population, though, it’s a simple task to estimate when Starlink might reach that milestone.
While SpaceX appears to be standing down Starlink launches for around two weeks to focus fully on Crew Dragon’s second operational astronaut launch (Crew-2), the company is expected to jump right back to rapid-fire Starlink launches in the last week or so of April. If, from that point on, SpaceX matches its Q1 2021 average and manages one Starlink mission every ~12 days, Starlink-28 could launch in late-June – and possibly even earlier. From then on, it’s just a matter of verifying each satellite’s health in space before allowing the spacecraft to boost up to their operational orbits.
In other words, barring unprecedented numbers of early satellite failures or unusually long orbit-raising periods, it’s likely that SpaceX will have enough operational satellites – around 1700 – for near-total, uninterrupted Starlink coverage of the inhabited world by the end of Q3 (September) 2021.

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.
