SpaceX to launch secret “Zuma” payload same day as Tesla Semi event
SpaceX has completed preparations and is ready to launch the highly secretive “Zuma” satellite(s) at 5pm/8pm PST/EST on Thursday, November 16th, the same day Tesla will be holding its semi-truck unveiling event.
Updated: SpaceX has rescheduled the Zuma mission.

The Zuma launch campaign has been veiled in an extraordinary level of secrecy for SpaceX and the US launch industry in general, and this has piqued the interest of many.
In the last decade or two, the United States military apparatus has launched many dozens of satellites, and secrecy on the order of Zuma is unusual to say the least. Missions for the National Reconnaissance Office (NRO) typically feature some level of media presence and have developed a community of fans in the age of social media, taking advantage of cartoonish mission logos that can often be entertaining, if not vaguely disturbing.

However, no federal agency has yet to announce involvement in Zuma. The full extent of public information available can be found in a handful of tweets, with drastically less official info available from a leaky source on Reddit. Thus far, Northrop Grumman is known to have at least procured Zuma’s launch from SpaceX, and the same statement indirectly suggested that Zuma was in fact a government-related mission. NRO is the obvious option, with the Air Force or another branch of the US military or intelligence apparatus also a distinct possibility. It is entirely possible that the nature and parent of the mission will remain secret for the indefinite future, even after its launch.
Nevertheless, a handful of details allow us to speculate in greater detail. In May 2017, SpaceX launched NROL-76, a Department of Defense satellite that was intriguingly observed to have made very close passes to the International Space Station, far too close to have been a coincidence. Based on Notices to Airmen (NOTAMs) filed with the FAA and discussed earlier this week, it appears Zuma may be placed in an orbit very similar to that of NROL-76, suggesting that Zuma could be an iteration on NROL-76’s supposed orbit-to-orbit data gathering capabilities. This time, however, agency involvement has been completely shadowed. A blank fairing, sans any NROL-reminiscent logo, will be the tell-tale sign come tomorrow, when Teslarati’s launch photographer Tom Cross arrives at Kennedy Space Center for camera setup.
Northrop Grumman on #SpaceX Zuma launch: "This represents a cost effective approach to space access for government missions. Northrop realizes that this is monumental responsibility and has taken great care to ensure the most affordable and lowest risk scenario for Zuma."

Meanwhile, as has become shockingly routine, SpaceX’s Falcon 9 first stage, core 1043, will conduct a Return to Launch Site (RTLS), landing at LZ-1 just a few miles from its launch pad. Like NROL-76, we can expect live coverage of the second stage and payload to end immediately after stage separation; bittersweet but esoteric fans, but likely to result in a unique focus on the stage returning to Earth.
On the horizon
Possibly more exciting than the launch itself, Zuma is expected to be the last launch from SpaceX’s Kennedy Space Center LC-39A facilities until Falcon Heavy, currently aiming for an inaugural flight around December 29th. After a solid year of repairs and refurbishment, SpaceX’s LC-40 launch pad is anticipating a return to flight operations with the CRS-13 Cargo Dragon mission on December 4th. Located within the Cape Canaveral Air Force Station just a few miles south of LC-39A, LC-40 suffered widespread damage after a Falcon 9 catastrophically failed while preparing for a static fire test on the pad.
Despite the tragic loss of vehicle and the Amos-6 payload, SpaceX has maintained a strong relationship with the owner, Spacecom, and was recently chosen for both a contractual reflight in 2019 and an additional launch in 2020.
SpaceX has also made great strides since returning to flight after Amos-6 in January 2017, and has enjoyed a truly groundbreaking year of incredible progress towards the goal of rapid reusability. Quite fittingly, LC-40 is expected to return to action while hosting yet another commercial reuse of a Falcon 9 first stage, this time with the hugely significant approval of NASA. The space agency has yet to make this decision resoundingly public, but respected industry insider NASASpaceflight.com has stated that it is all but in stone at this point in time. In a sense, the disaster that severely damaged LC-40 acted as a since-heeded wake-up call for SpaceX, and the venerable pad will rise from those ashes into a new era of reusable rocketry, led wholeheartedly by SpaceX.

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 designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.

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.
