Published as part of an August 2019 environmental assessment (EA) draft for Starship’s prospective Pad 39A launch facilities, SpaceX revealed plans for a truly mindboggling number of annual Falcon 9 and Falcon Heavy launches by 2024.

As environmental planning documents, the figures should be taken with a large grain of salt and be treated as near-absolute ceilings rather than practical goals. Nevertheless, SpaceX revealed plans for its two Florida launch sites (LC-40 and LC-39A) to ultimately support as many as 70 annual launches of Falcon 9 and Heavy by 2024, less than five years from now.

Simply put, even the most dogmatic fan would have to balk at least a little bit at the numbers SpaceX suggested in its Starship EA draft. More specifically, SpaceX apparently has plans to support as many as 20 annual Falcon 9/Heavy launches from Pad 39A and an incredible 50 annual Falcon 9 launches from LC-40 as early as 2024.

“SpaceX plans to increase the Falcon launch frequency to 20 launches per year from LC-39A and up to 50 launches per year from LC-40 by the year 2024. However, as Starship/Super Heavy launches gradually increase to 24 launches per year, the number of launches of the Falcon would decrease.“

Two obvious options

Given just how significant of an increase a 70-launch annual cadence would be for SpaceX relative to their current record of 21 launches, it’s entirely possible that these numbers are really just a pipe dream included in a pending environmental assessment to hedge bets just in case a similar launch frequency is achieved over the next five years.

On the other hand, it’s possible that SpaceX – just now coming into the ability to reliably achieve a much higher cadence – has coincidentally become payload-constrained at almost the same time, meaning that the company’s customers’ payloads just aren’t ready for launch. This would explain, for example, why SpaceX has only launched 10 times this year when the company had already completed 15 launches by August 2018.

Additionally, it can be almost unequivocally assumed that all but 15-20 of those supposed 70 annual launches would come from SpaceX’s own internal demand for Starlink launch capacity. Assuming no improvements between now and 2024, 50 Falcon 9 launches could place as many as 3000 Starlink satellites in orbit in a single year, equivalent to more than 25% of the entire proposed ~11,800-satellite constellation.

Barring regulatory changes to US Federal Communications Commission (FCC) and International Telecommunication Union (ITU) requirements, SpaceX must launch at least half of all Starlink satellites (~5900) by November 2024 and finish launching the remaining ~5900 by November 2027. If SpaceX fails to reach those deployment milestones, the company runs the risk of losing Starlink’s domestic and international licenses to operate.

This would help to explain why SpaceX says that it’s planning to reach a maximum cadence of 70 annual launches “by 2024”, given that 2024 will be a pivotal year in the eyes of regulations currently in effect for Starlink.

Starship confusion

As noted in the quote above, SpaceX plans to eventually phase out Falcon 9 and Heavy launches as the company’s next-generation Starship and Super Heavy launch vehicle gradually comes online, proves itself reliable, and begins operational launch activities. According to SpaceX, given just how much mass Starship can nominally launch relative to both Falcon 9 and Heavy, far fewer launches will be needed to accomplish the tasks that would otherwise require several times more launches of SpaceX’s smaller vehicles.

SpaceX’s initial Environmental Assessment for Starship launches from Pad 39A caps the rocket’s maximum cadence at 24 annual launches. Oddly, this directly contradicts the goals set for Starship (formerly BFR) by CEO Elon Musk and SpaceX more generally. By building a launch vehicle that is fully and rapidly reusable, the goal has long been to deliver cheap, aircraft-like access to orbit at a completely unprecedented scale.

Starship was never meant to lower SpaceX’s annual launch cadence. (SpaceX)

This would technically mean that SpaceX could actually dramatically increase its launch cadence without increasing costs, allowing the company to perform currently nonsensical missions where Starship might launch payloads weighing just 5-10% of its total payload capacity. Airline operations routinely do things of a similar nature, sometimes flying just a fraction of their maximum passenger load to destinations for a variety of reasons.

Additionally, SpaceX has consistently indicated that Starship will rely heavily on orbital refueling to accomplish its ultimate deep space ambitions. Previous presentations from Elon Musk have shown that launches to the Mars or Moon with significant payload would require no fewer than five separate tanker launches and orbital refuelings, all of which would classify as one of the 24 annual launches SpaceX has described in its August 2019 EA draft. On their own, launching two Starships to Mars with 100 tons of payload each would require no fewer than 10-12 launches.

Ultimately, it’s unwise to draw any substantial conclusions from an Environmental Assessment like the one the above information has been taken from. This 39A-specific EA also ignores the possibility of a similar launch facility being developed in Boca Chica, Texas, which SpaceX explicitly acknowledges.

This particular draft is also the first Starship-related EA ever filed by SpaceX, and the company may thus be treating it more as a bare minimum with the intention of eventually pursuing far more ambitious launch rates once Starship has been established.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Published

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion

Published

By

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.

Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”

The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.


The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.

Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.

Tesla plans big safety improvements for Full Self-Driving v15

Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.

Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
