SpaceX’s Starlink launch debut to orbit dozens of satellites later this month

SpaceX President and COO Gwynne Shotwell has revealed that the company’s first dedicated Starlink launch is scheduled for May 15th and will involve “dozens” of satellites.

Corroborated by several sources, the actual number of Starlink satellites that will be aboard Falcon 9 is hard to believe given that it is a satellite constellation’s first quasi-operational launch. Suffice it to say, if all spacecraft reach orbit in good health, SpaceX will easily become the operator and owner of one of the top five largest commercial satellite constellations in the world with a single launch. Such an unprecedentedly ambitious first step suggests that the perceived practicality of SpaceX’s Starlink ambitions may need to be entirely reframed going forward.

From 0 to 100

In short, it’s hard to exaggerate just how much of a surprise it is to hear that SpaceX’s very first Starlink launch – aside from two prototypes launched in Feb. 2018 – will attempt to place “dozens” of satellites in orbit. Competitor OneWeb, for example, conducted its first launch in February 2019, placing just six satellites in orbit relative to planned future launches with 20-30. To go from 2(ish) to “dozens” in a single step will break all sorts of industry standards/traditions.

Despite the ~15 months that have passed since that first launch, SpaceX’s Starlink team has really only spent the last 6-9 months in a phase of serious mass-production buildup. As of now, the company has no dedicated satellite factory – space in Hawthorne, CA is far too constrained. Instead, the design, production, and assembly of Starlink satellites is being done in 3-4 separate buildings located throughout the Seattle/Redmond area.

SpaceX’s Starlink team has managed to transition almost silently from research and development to serious mass-production (i.e. dozens of satellites) in the space of about half a year. The dozens of spacecraft scheduled to launch on SpaceX’s first dedicated mission – likely weighing 200-300 kg (440-660 lb) each – have also managed to travel from Seattle to Cape Canaveral in the last few months and may now be just a few days away from fairing encapsulation.

To some extent, the first flight-ready batch of “dozens” of satellites are still partial prototypes, likely equivalent to the second round of flight testing mentioned by CEO Elon Musk last year. This group of spacecraft will have no inter-satellite laser (optical) links, a feature that would transform an orbiting Starlink constellation into a vast mesh network. According to FCC filings, the first 75 satellites will be of the partial-prototype variety, followed soon after by the first spacecraft with a more or less finalized design and a full complement of hardware.

If this is just step one…

Meanwhile, Shotwell – speaking at the Satellite 2019 conference – suggested that SpaceX could launch anywhere from two to six dedicated Starlink missions this year, depending on the performance of the first batch. Put a slightly different way, take the “dozens” of satellites she hinted at, multiply that number by 6, and you’ve arrived at the number of spacecraft she believes SpaceX is theoretically capable of producing and delivering in the next 7.5 months.

“Dozens” implies no less than two dozen or a bare minimum of 144 satellites potentially built and launched before the year is out. However, combined with a target orbit of 450 km (280 mi) and a planned drone ship booster recovery more than 620 km (385 mi) downrange, 36, 48, or 60 satellites seem far more likely. Tintin A/B – extremely rough, testbed-like prototypes – were about 400 kg (~900 lb) each.

As an example, SpaceX’s eight Iridium NEXT satellite launches had payloads of more than 10,000 kg (22,000 lb), were launched to an orbit around 630 km (390 mi), and required a upper stage coast and second burn on-orbit. Further, Iridium missions didn’t get the efficiency benefit that Starlink will by launching east along the Earth’s rotational axis. Despite all that, Falcon 9 Block 5 boosters were still able to land less than 250 km (155 mi) downrange after Iridium launches. Crew Dragon’s recent launch debut saw Falcon 9 place the >13,000 kg (28,700 lb) payload into a 200 km (125 mi) orbit with a drone ship landing less than 500 km (310 mi) downrange, much of which was margin to satisfy safety requirements.

Starlink-1’s target orbit is thus a third lower than Iridium NEXT, while its drone ship will be stationed more than 2.5 times further downrange. Combined, SpaceX’s first Starlink payload will likely weigh significantly more than ~13,000 kg and may end up being the heaviest payload the company has yet to launch.

Assuming a payload mass of ~14,000 kg (~31,000 lb) at launch, a worst-case scenario with ~400 kg spacecraft and a 2000 kg dispenser would translate to 30 Starlink satellites. Cut their mass to 300 kg and the dispenser to 1000 kg and that rises to ~45 satellites. Drop even further to 200 kg apiece and a single recoverable Falcon 9 launch could place >60 satellites in orbit.

Of course, this entirely ignores the elephant in the room: the usable volume of SpaceX’s standard Falcon payload fairing. It’s unclear how SpaceX would fit 24 – let alone 60 – high-performance satellites into said fairing without severely constraining their design and capabilities. SpaceX’s solution to this problem will effectively remain unanswered until launch, assuming the company is willing to provide some sort of press release and/or offer a live view of spacecraft deployment on their webcast. Given the cutthroat nature of competition with the likes of OneWeb, Telesat, LeoSat, and others, this is not guaranteed.

At the end of the day, such a major leap into action bodes extremely well for SpaceX’s ability to realize its ambitious Starlink constellation, and do so fast. For those on Earth without reliable internet access or any access at all, the faster Starlink – and competing constellations, for that matter – can be realized, the sooner all of humanity can enjoy the many benefits connectivity can bring. For those that sit under the thumb of monopolistic conglomerates like Comcast and Time Warner Cable, relief will be no less welcome.

Stay tuned as we get closer to Starlink-1’s May 15th launch date. Up next is a static fire of the mission’s Falcon 9 rocket, perhaps just two or three days from now.

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).

Published

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.”

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.
