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.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
