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.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion

Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.

The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.

But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.

Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.

However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.

Wireless for Operation, Wired for Downtime

It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.

The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.

In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.

Induction Charging Challenges

Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.

While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.

Production Timing and Potential Challenges

With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.

It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.

In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years. 

The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.

Dry cathode 4680 cells

In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.

The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”

Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.

4680 packs for Model Y

Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla: 

“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”

The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line

This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.

Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.  

Optimus 4 production

In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas. 

This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4. 

“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.

How big Optimus could become

During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world. 

“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP. 

“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
