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

Tesla shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
