SpaceX’s internet satellite strategy faces possible setback (Correction: It’s actually in great shape)

Published

on

Correction: Upon further analysis of FCC filings and proposed updates to ITU regulations, SpaceX’s Internet constellation is on much steadier ground than it initially appeared to be, and the FCC decision made on September 26 2017 to update its NGSO FSS regulations is likely to help SpaceX far more than it might harm the company. 

The ITU has since 2015 taken a stance that aligns more with the FCC’s cooperative spectrum sharing policy and did not intend for Part 5 of its Radio Regulations to be interpreted as a “first come, first serve” attitude. Specifically, the ITU’s 2017 Rules of Procedure pointedly state in Article 9.6 (Word document download) that those rules were not intended “to state an order of priorities for rights to a particular orbital position” and that “the [interference] coordination process is a two way process”. An ex parte filed with the FCC (PDF download) by SpaceX on September 15 stated SpaceX’s support for these international and domestic policy adoptions, as well as the FCC International Bureau’s responsive consideration of SpaceX’s own suggestions. 

The company’s first two test satellites could still launch later this year

The U.S. Federal Communications Commission (FCC) responded September 7th to requests for modification to existing satellite communications regulations and FCC practices from a number of prospective constellation operators, including OneWeb, Telesat, and SpaceX.

The FCC ultimately decided to avoid one major rule change that could force SpaceX to completely reconsider its strategic approach to its proposed Low Earth Orbit broadband constellation.

To grossly oversimplify, SpaceX had requested that the FCC apply their non-interference rules for lower orbit communications satellites to internet constellations operating both inside and outside the physical United States. These rules require that communication satellites operating in non-geostationary orbits (NGSO) share the available wireless spectrum equally among themselves when two or more satellites pass within a certain distance of each other relative to ground stations. In simpler terms, consider your smartphone’s cellular connectivity. The FCC’s rule for satellites in lower orbits can be thought of like multiple smartphones using the same cell tower to access the internet: the cell tower simply acknowledges the multiple devices it needs to serve and allows each device a certain amount of bandwidth.

However, the FCC is admittedly a domestic Commission focused on administering communications rules and regulations in the United States, and an agency already exists for coordinating global communications needs, called the International Telecommunication Union (ITU). The ITU’s Radio Regulations are considerably more simplistic. Rather than the FCC’s more nuanced and reasonable methods of spectrum sharing, the ITU allows the first satellite operator actively using a certain orbit or spectrum to become the primary coordinator for all interference issues. Put more simply, it gives those who launch communications satellites first a “first come, first serve” advantage that lets those entities then set the rules for interference with their constellation.

Both OneWeb and Telesat, companies also interested in launching global broadband constellations, are licensed in countries other than the United States, meaning that the FCC has given the ITU precedent in deciding how to deal with SpaceX’s potential constellation interference. SpaceX’s proposed constellation of at least several thousand satellites ends up being at a distinct disadvantage simply because it would take far longer for SpaceX to even partially complete its constellation when compared with competitors like OneWeb, who expect to finish launching the first phase of their constellation several hundred satellites by the end of 2020. Under the ITU’s regulations, SpaceX could be forced by competitors to effectively step on eggshells around their constellations by avoiding interference to the furthest extent possible, rather than simply sharing spectrum in the brief periods where different satellites temporarily interfere with each other.

While the FCC’s choice to cede international interference coordination to the ITU is a huge blow to SpaceX’s proposed internet constellation efforts, the same September 7th report also eased a handful of other requirements that would have proven difficult for SpaceX’s massive constellation. For geostationary constellations, the FCC previously required that all satellites be launched within a period of six years, with failure to do so resulting in a revoked license for the company in question. In a small concession to SES, O3b, and SpaceX, the FCC now plans to require that 50% of lower orbit satellite constellations be launched within six years of receiving an FCC license. This would still be a massive challenge for SpaceX’s plan of 4,425 initial satellites and a follow-up constellation of more than 7,000 additional satellites (PDF download).

The FCC’s September 7th report will not become final unless it is passed by vote in a September 26th Open Commission Meeting. It is possible that SpaceX council will make a statement protesting the FCC’s decision, but it is nevertheless likely that the FCC’s report will be accepted and become official. While the LEO internet constellation has remained a low priority for SpaceX since it was revealed in 2015, the company has steadily continued work on the project and SpaceX has every reason to continue pursuing it given the potential profit margins it could produce. In spite of the now expanded difficulties lying ahead, SpaceX appears to be preparing for the first launch of two test satellites related to its internet constellation efforts. The move is seen as a likely attempt to tag along as passengers during SpaceX’s launch of PAZ, a Spanish earth imaging satellite, during the final three months of 2017.

Elon Musk is scheduled to reveal more details on SpaceX’s Mars exploration and colonization efforts on September 29th. He has stated that this presentation will focus more on the “how” of colonizing Mars, revealing how exactly SpaceX thinks it can fund the development of its Interplanetary Transport System. Musk also confirmed several weeks ago that SpaceX had reduced the size of the ITS rocket to a still-massive diameter of 9 meters, and sources inside the company have also indicated that the company is thinking about modifying its LC-39A Florida launch pad to support both Falcon and ITS vehicles. SpaceX recruiters revealed earlier this week that SpaceX also intends to have their Boca Chica, Texas launch pad, which is currently under construction, be capable of eventually launching ITS-sized vehicles once it comes online in 2019 or later.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.

Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”

The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.

Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.

Configuration Seats 0 to 60 mph
Performance 2 under 1.6 s
Thrust 2 under 0.9 s
Rocket 1 under 0.59 s

Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Tesla Roadster Highlights

  • Aero and suction: a multi-mode fan and ground sealing system pulls air from under the car and can hold it upside down even when stationary. There are also active wings and a Track Mode that lowers the car.
  • Controls and thrusters: steer-by-wire with a yoke. The cold gas thrusters use all-electric actuators for micro adjustments that stabilize the car in flight.
  • Weight: magnesium, titanium and carbon fiber, manual controls and a fixed seat position.
  • Design: hidden headlights, a full-length taillight, Ano White paint inspired by aerospace coatings, and gold tinted glass modeled on spacesuit visors.

  • Road use: Tesla notes the car is not approved for public road use, and that Rocket isn’t available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store

Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.

Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.

The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.

The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.

The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.

The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.

Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.

So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
