SpaceX confirms Starlink launch plans hours before Thursday liftoff
Update: Waiting longer than it ever has before, SpaceX finally confirmed it will attempt to launch Starlink 4-3 less than seven hours before the mission’s planned 6:12 pm EST (23:12 UTC), December 2nd liftoff. SpaceX has yet to publish any additional details or webcast links for the launch but should (in theory) do so within the next few hours.
SpaceX has raised Falcon 9 vertical for a record-breaking Starlink and rideshare mission known as Starlink Group 4 Launch 3 (4-3).
According to Spaceflight Now, Falcon 9 rolled out to SpaceX’s Cape Canaveral LC-40 launch pad and was expected to perform a static fire test as early as Monday, November 29th, briefly firing up the mystery flight-proven booster’s nine Merlin 1D engines to verify the rocket’s health. As of early Wednesday, that static fire has yet to happen, leaving SpaceX just ~36 hours to test the rocket before its current 5:57 pm EST (22:57 UTC), December 2nd launch target.
Despite its name, Starlink 4-3 will be SpaceX’s second Group 4 launch and is scheduled to deliver another 50-52 laser-linked Starlink V1.5 satellites to low Earth orbit. Normally, Starlink 4-3 would be carrying 53 Starlink satellites but SpaceX will instead swap out two or three Starlink satellites for two rideshare payloads from Earth observation company Blacksky.
Starlink 4-3 will be SpaceX’s fifth Starlink rideshare mission and second with Earth imaging satellites from Blacksky after Starlink V1 L9’s successful August 2020 launch. Each weighing around 60 kg (130 lb), Blacksky’s small ‘Gen2’ satellites are designed to capture images of Earth at resolutions of up to 0.9 meters per pixel. If successful, the launch will raise the number of operational Blacksky satellites in orbit from 8 to 10. Another two launches are expected to occur in the next two months for a total of 14 satellites.
Like past Starlink rideshares, SpaceX will likely launch Falcon 9 to a slightly higher orbit than usual – tailored to each customer’s needs. For SXRS-2, Spaceflight says Falcon 9 will deploy all Starlink and rideshare payloads in a (likely circular) 430 km (270 mi) low Earth orbit. In comparison, Falcon 9 deployed Starlink 4-1 in an orbit roughly 340 by 220 km.
For SpaceX, Starlink 4-3 will set at least two major spaceflight records. First, if all goes well, it will be SpaceX’s 27th launch of 2021 – a new record for annual launch cadence. Though CEO Elon Musk originally hoped for 40-48 launches this year, it appears that SpaceX will still manage around 29-31 by the end of December. However, if SpaceX managed to excise the apparent Starlink production gremlins that partly caused its launch cadence to plummet from 20 missions in the first half of 2021 to ~10 in the second half, 2022 could potentially meet Musk’s 2021 expectations.
Additionally, as pointed out by a Teslarati reader, Starlink 4-3 could also see Falcon 9 become the first American rocket in history to successfully complete more than 100 orbital launches in a row, narrowly beating out McDonnell Douglas’ retired Delta II rocket for the title. Earlier this year, many outlets already reported that SpaceX’s May 26th Starlink-28 launch was its 100th consecutive launch. While true in a very literal sense, it ignores SpaceX’s infamous Amos-6 Falcon 9 failure, which occurred well before liftoff but still destroyed both the rocket and payload. Following NASA’s DART mission earlier this month, which was Falcon 9’s unequivocal 100th launch success, Starlink 4-3 will be Falcon 9’s 101st orbital launch since Amos-6.
Only Russia’s R-7 (Soyuz) rockets – the most-launched rocket family in history – have successfully launched more times in a row. Since 1966, Soyuz rockets have launched more than 1900 times and the family has repeatedly completed 100 consecutively successful launches over its decades of operation. Eleven years after its debut, Falcon 9 currently stands at 127 fully successful launches – a lifetime away from matching Soyuz but still well on its way to a thoroughly impressive second place.
Stay tuned for official confirmation from SpaceX of Starlink 4-3’s pending static fire and December 2nd launch date.

Tesla Cybercab and Semi have more in common than you might think
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.

Elon Musk weather update tips Tesla Roadster speculation into Plaid Mode
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 snags $30B in fresh credit lines for expanding its biggest projects
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.
